Hyundai, part of a very exclusive club offering hydrogen fuel cell vehicles in the U.S., has followed its initial Tucson FCEV with the all-new Nexo. It’s available only in California where hydrogen fueling opportunities, while limited, exist in greater numbers compared to other states.
The Nexo represents a step forward for FCEVs in that Hyundai is selling the 5-passenger hatchback and not just leasing it, as is typically the case with hydrogen vehicles. It also uses a purpose-built platform rather than being based on an existing model like the Tucson FCEV.
As a hydrogen fuel cell vehicle, the Nexo’s fuel cell takes in hydrogen and oxygen to create electricity for powering an electric motor, with zero emissions. The heart of the Nexo is its 95-kW proton-exchange membrane fuel cell stack and 1.6-kWh lithium-ion battery pack. These supply electricity to a 161-horsepower, 291 lb-ft AC induction motor located beneath the hood. Power is transferred to the road through a single-speed, direct-drive gearbox. Hydrogen is stored in three 10,000 psi tanks with a total capacity of 156 liters, delivering an EPA estimated driving range up to 380 miles.
Hyundai reduced the size and weight of the fuel cell compared to that used in the earlier Tucson FCEV. The new fuel cell uses only 56 grams of expensive platinum rather than the Tucson’s 78 grams. Hyundai also improved cold-weather performance so the fuel cell starts in temperatures as low as -22 degrees F. Like the Tucson and other fuel cell vehicles, refueling with hydrogen can be done in as little as five minutes.
Audi's new 2019 e-tron electric SUV joins Jaguar and Porsche in giving Tesla some serious competition. The automaker’s first-ever all-electric vehicle looks much like the rest of the Audi lineup, foregoing the temptation to go too futuristic or quirky in an effort to stand out as an electric. Its iconic Audi grille reinforces the sense of normalcy even as it handles the distinctly-electric job of directing cooling air to pass under the battery pack. Some electrification cues are provided, though, as the e-tron features slats running across the rear bumper that highlight the lack of tailpipes. Lights in the front are also designed to look like the bars of a charge status indicator. A dark colored section along the sides show battery pack location.
Efficient aerodynamics and other efficiency-enhancing touches were important in designing the e-tron, which features a drag coefficient of just 0.30. Features include cooling ducts for the e-tron’s front brakes and its adaptive, speed-dependent air suspension. Standard ultra-low rolling resistance 20-inch wheels are aerodynamically optimized. Full underbody cladding incorporates an aluminum plate to help protect the battery and also lower drag.
The e-tron's electric quattro all-wheel drive uses two asynchronous motors, each driving one set of wheels. Single-stage transmissions transfer torque to the axles via differentials. At moderate cruising speeds, the e-tron is powered mainly by the rear motor. The battery pack's location between the axles plus the low positioning of other drive components results in low center of gravity. Weight distribution is approximately 50:50. A driver can select from seven different driving modes, from comfortable to sporty, that alter suspension stiffness, steering responsiveness, and how aggressively the SUV accelerates.
Two electric motors accelerate the e-tron from 0-60 mph in 5.5 seconds with a top speed of 124 mph. It can tow up to 4000 pounds when equipped with the optional tow package. While EPA has yet to provide driving range numbers, testing in Europe resulted in 248 miles from the 95 kWh battery pack. EPA's testing here tends to yield somewhat lower range numbers.
Audi put heavy emphasis on recuperating as much energy as possible. Depending on driving conditions, terrain, and driving style, regenerative braking can provide as much as 30 percent of the e-tron’s range. The driver can select how aggressively the car uses this system, allowing for "one pedal" driving where taking the foot off the throttle will bring the car to a full stop using only regenerative braking.
The e-tron is available with a full range of standard or optional driver assistance packages including adaptive cruise assist, intersection assist, rear cross traffic assist, lane change and vehicle exit warning, and park steering assist. It comes in three trim levels - Premium Plus, Prestige, and First Edition. A panoramic glass sunroof is standard.
The popular Toyota RAV4 was fully-redesigned this model year to meet the requirements of today's ever-expanding SUV market. Now in its 5th generation, the 2019 RAV4 is built on the Toyota New Global Architecture (TNGA-K) platform and engineered to be more efficient. Both conventionally-powered and hybrid versions of the RAV4 are offered, with blue accents on the Toyota logo and hybrid badges the only visual cues that set the RAV4 Hybrid apart from its non-hybrid counterpart.
Power in the hybrid is delivered by Toyota’s Hybrid System II, which in this model uses a 2.5-liter, four-cylinder Atkinson cycle engine producing 176 horsepower and 163 lb-ft torque. The system’s two electric motors deliver 118 horsepower and 149 lb-ft torque to the front wheels, with 54 horsepower and 89 lb-ft torque to the rear wheels. Combined hybrid system output is 219 horsepower. All-wheel drive is a standard feature on the hybrid, and the RAV4 Hybrid is very capable off-roading as we proved during our time driving off-road trails and in challenging conditions.
The RAV4 Hybrid’s electronically-controlled, continuously variable transmission (ECVT) comes with sequential shift modes. Sport mode changes throttle mapping and the way the transmission operates for a more responsive feel. An Eco mode optimizes fuel economy. EV mode provides an extremely limited all-electric range using light throttle.
The hybrid’s nickel-metal hydride battery pack is located beneath the rear seat so interior space is not compromised. In fact, there is a bit more cargo room compared to the previous generation RAV4 since the battery pack is more compact. An 8.0-inch touchscreen displays the hybrid powertrain’s battery activity.
New to the 2019 RAV4 HV models, Predictive Efficient Drive essentially reads the road and learns driver patterns to help optimize hybrid battery charging and discharging operations, based on actual driving conditions. The system accumulates data as the vehicle is driven and ‘remembers’ features such as hills and stoplights, for example, and adjusts hybrid powertrain operation to maximize efficiency.
The 2019 RAV4 Hybrid is equipped with the second generation of Toyota Safety Sense (TSS 2.0), which includes a Pre-Collision System with Pedestrian Detection, Full-Speed Range Dynamic Radar Cruise Control, Lane Departure Alert with Steering Assist, Automatic High Beam, Lane Tracing Assist, and Road Sign Assist. Blind Spot Monitor with Rear Cross Traffic Alert and Rear Cross Traffic Braking are standard on XLE grade and above, and optional for the LE. Limited grade adds standard Intelligent Clearance Sonar, which is available on XLE and above.
Other available safety technologies include a panoramic backup camera with customizable dynamic grid lines. The Limited grade adds a Bird’s Eye View Camera with perimeter scan, overhead 360-degree view, and curb view. Every model is equipped with Entune 3.0 multimedia, including Wi-Fi Connect powered by Verizon, Amazon Alexa, Google Assistant capability, and Apple CarPlay compatibility.
The RAV4 Hybrid achieves an admirable 41 mpg in the city and 38 mpg on the open road, at an entry price of $27,700.
Tesla’s Model 3 was promised from the beginning to be an advanced electric sedan at an affordable $35,000 entry price. That, as anyone who has followed Tesla with any kind of regularity, has been an elusive goal as only higher-end and much more expensive versions of the Model 3 have been offered. And now…the $35,000 Model 3 is finally a reality.
Model 3 is a stylish and high-tech sedan offering a signature Tesla look and lots of advanced technology. Tesla’s third all-electric vehicle, the Model 3 follows in the footsteps of the well-regarded Model S sedan and Model X crossover SUV. Like these vehicles, the Model 3 is fast and fun to drive. Importantly, it does what Teslas are known to do – offer all-electric driving from about 220 miles up to 310 miles before requiring a recharge, which does a lot to ease range anxiety.
Just as Tesla’s approach to being an automaker is different, so too are its cars. Compared to the Model X, which the company packed in as many ‘firsts’ as possible – a crossover with gullwing-like ‘falcon’ doors and the industry’s largest windshield – the Model 3 is more aligned with the needs of mass production. In fact, Tesla describes the Model 3 as ‘smaller and simpler’ than its predecessors to make it more affordable than the Model S.
The $35,000 entry price tag is important since the Model 3 has been widely-promoted as a $35,000 ‘everyman’s electric vehicle’ affordable to the masses, even as the cheapest model available was initially $49,000, then $46,000, and ultimately $43,000 before Tesla finally made the leap to its recently-announced $35,000, slightly decontented base model. At that price it’s doubtful that Tesla will make money, and in fact it wasn’t long ago when Tesla CEO Elon Musk said the company would lose money on the Model 3 at that price point. An array of industry experts agree with that assessment. But that’s another story.
If not an exercise in simplicity, then perhaps the Model 3 is a statement that ‘less-is-more,’ even as it delivers desired levels of performance, range, technology, and safety. For example, rather than more costly aluminum construction like the Model S and Model X, the Model 3 uses both aluminum and less-costly steel. Its interior is also a model of simplicity devoid of instrumentation and external controls, knobs, or switches, with everything – including the speedometer – incorporated into its 15-inch center-mounted touchscreen display.
Buyers have a choice of battery packs and motors that deliver varying levels of performance and range. The lowest motor output currently available is estimated to offer 220 horsepower and rear-wheel drive, with a range of 220 miles. The dual motor model features 450 horsepower with all-wheel drive and a range of 310 miles.
Like all Tesla models, the Model 3 includes the hardware needed in the future for full self-driving, although this capability is dependent upon extensive software validation and local regulatory approval. Model 3 offers forward radar, eight cameras, and 12 ultrasonic sensors that enable an array of safety and driver-assist functions including automatic emergency braking, collision avoidance, and side collision warning. Over-the-air software updates are part of the package and Tesla’s AutoPilot semi-autonomous driving system is an available option.
Tesla now offers two levels of Connectivity: Standard that is free and Premium that comes at a modest annual cost. Standard Connectivity offers basic maps and navigation, music and media over Bluetooth, and software updates over Wi-Fi. Both receive maps and navigation functionality, traffic-based routing, trip planner, and Supercharger stall availability. All cars with Standard Connectivity will simply need to connect to a Wi-Fi network to receive software updates. Premium Connectivity adds satellite-view maps with live traffic visualization, in-car streaming music and media, and over-the-air software updates via Wi-Fi and cellular.
In an interesting twist to the $35,000 Model 3 saga, Tesla shuttered some of its stores and galleries in an effort to save money in tandem with the lower-cost Model 3 availability, with the intention of potentially closing all of them and exclusively selling online. The company then changed its mind and kept most of its Tesla stores and galleries open. Again, another story…so stay tuned.
The Nissan LEAF benefits from early electrics like the circa-1998 Nissan Altra EV, the first model to use lithium-ion batteries. The Altra EV was one of many electrics explored during Nissan’s decades-long electric vehicle development program, including the Future Electric Vehicle (FEV), FEV II, Prairie Joy EV, Nissan Hypermini, Altra EV, and of course the LEAF. To lend insight into the early years of Nissan’s electric vehicle development, we present the following article from the Green Car Journal archives, as it was originally published in June 1998.
Excerpted from June 1998 Issue: The Nissan Altra EV, an electrified iteration of the all-new R’nessa minivan, an internal combustion model sold only in Japan, created quite a stir at its official North American debut at this year’s 1998 Greater L.A Auto Show.
The reason? It’s the first time any production electric vehicle has used lithium-ion batteries, scaled-up versions of the batteries found in the highest-end notebook computers and video cameras. Just as lithium-ion allows these portable devices to operate longer on battery power, this advanced battery technology also provides an EV with a longer single charge driving range – 120 miles in the case of this minivan.
It could have been more. Nissan chose to go with a minivan because of its universal appeal and functionality. However, there was a desire on the part of some Nissan executives to go with a smaller, lighter EV because the Li-ion batteries could have provided a stunning 200 mile single-charge driving range in a smaller platform. Instead, the automaker chose a platform that weighs in at just over 100 pounds more than Honda’s EV Plus.
The Altra EV’s Li-ion battery pack consists of 12 modules of eight cells connected in series, or a total of 96 cells, each measuring 2.6″ in diameter and 16″ in length. A Hughes-type inductive charging system, the same as GM’s EV1, is used on the Altra EV. A full charge from empty takes about five hours.
The decision to integrate Sony Li-ion batteries represents substantial vision on the part of Nissan, and also, it seems, an ability to absorb significant short term losses. While Nissan sources will not officially comment on the actual cost of the Li-ion battery pack, insiders say that early versions cost somewhere between $50,000 to $70,000 each. Obviously, these costs will drop dramatically and quickly as the technology advances and greater numbers of these batteries are produced. In the meantime, high costs for early EVs used in limited demonstrations are to be expected.
Power is provided by a 83 horsepower permanent magnet synchronous motor and a 32-bit high-speed RISC motor controller processor. The motor features a compact design that weighs just 85 pounds. This electric powertrain achieves a high overall energy efficiency lf approximately 90 percent under ordinary driving conditions.
Green Car Journal editors had the opportunity to put the Altra EV through its paces at the automaker’s Tochigi test track in Japan. This test drive proved the Altra EV to be quite a capable performer, with good acceleration and handling characteristics. In fact, no apparent shortcomings were detected other than some slight gear whine, not a surprising occurrence since this vehicle’s operation is otherwise silent, with no internal combustion engine or exhaust noise to mask normal mechanical sounds.
Inside, an innovative, titanium-colored digital instrument panel displays performance and charge status that was easy to read during our test drive. Comfortable seating for four is provided with front and mid-section bucket seats. A good amount of cargo area is provided at the rear.
This four-place seating configuration, rather than the six- or seven-place seating found in conventional minivans, is simply a concession to the need to keep total gross vehicle weight within certain limits to ensure optimum driving range. Everything, from vehicle weight to aerodynamics to rolling resistance, is crucial in electric vehicles that carry a very finite amount of energy onboard. This is an especially important consideration since the Altra EV carries an 800 pound battery pack mounted beneath the floorboard.
Nissan is bringing 30 Altra EVs to the U.S. for testing this year, mostly within its own employee fleet and in the fleets of several electric utilities. Nissan sources tell Green Car Journal that delivery of the first 15 Altra EVs from Japan is slightly behind schedule, but they are expected imminently. After the initial 30 examples arrive, an additional 90 Altra EVs are scheduled to be brought to the U.S. for placement with fleets by 2000.
Of course, the Altra EV represents but one highly visible part of this automaker’s electric vehicle program. By all accounts there’s also a hybrid electric variant coming, possibly based on the efficient Nissan Avenir developmental hybrid platform that Green Car Journal editors had the opportunity to test drive at the automaker’s Tochigi track in late 1997.
While this hybrid vehicle was clearly still in the development stage – much of the interior was devoted to battery placement and instrumentation – it was far enough along to prove the viability of Nissan’s hybrid work.
Tadao Takei, Nissan’s executive vice president, has been quoted as predicting a January 1999 launch of a Nissan hybrid EV in Japan. This follows the late-1998 launch of Toyota’s Prius hybrid EV in the Japanese market. Takei expressed doubt that Nissan would reach the current 3,000 unit-per-month production of the Prius, which was recently ramped up to meet unexpectedly high demand for the Toyota hybrid.
Still, the fact that Nissan is moving forward with a hybrid launch signals an important commitment to what promises to be an exciting and growing segment of the auto industry.

Along with models like the 2019 Jaguar I-PACE, Audi e-tron, and upcoming Porsche Taycan, we're seeing a new generation of high-tech battery-powered vehicles that bring an exciting new direction to legacy automakers. These models also have something important in common: They aim to disrupt Tesla, the industry’s de-facto electric car leader.
Disruption is a word thrown about with abandon these days as veritable institutions of business and commerce fall from grace, or at least profitability, at the hands of an ever-changing and disruptive world. Think Sears, Borders, and Kodak. The list of major companies disrupted – either gone, a shadow of their former self, or on the ropes – continues to grow. While the auto industry has largely escaped this same fate, change is definitely in the wind. And its bogeyman in recent years has clearly been Tesla.
We’ve seen the auto industry disrupted before, not by innovators but rather by geo-politics, circumstance, and a lack of long-term vision. The Arab Oil Embargo of 1973 and the 1979 Oil Crisis that brought serious gas shortages were a result of political disruption. It was a time when stations ran out of gas, lines of cars snaked for blocks as drivers tried desperately to keep their tanks full and their car-dependent lives on track, and consumers looked for more fuel-efficient vehicles to ease their pain. The problem, however, was there were few fuel-efficient models being produced since there had been no particular demand for them. The auto industry had to adapt, but with typically long product cycles it would take years to adequately fill this need.
Segue to 2003 and the launch of Tesla Motors, an occurrence that seemed interesting but hardly a threat to legacy automakers. Its high-tech Tesla Roadster introduced in 2008 – based on engineless ‘gliders’ produced by Lotus – proved that electric cars could be sporty, fun, and go the distance in ways that all other electrics before it could not, to the tune of 250 miles of battery electric driving on a single charge. Then came the Tesla designed-and-built Model S, Model X, and the new-to-the-scene Model 3. Clearly, the battle for leadership in electric cars was underway.
The auto industry’s penchant for innovation has always characterized its giants. Over its long history, this is an industry that brought us the three-point safety belt, airbags, anti-lock braking, cruise control, direct fuel injection, electronic ignition, and near-zero emission gasoline engines. And let us not forget Kettering’s invention of the electric starter that first saw use in 1912 Cadillacs, an innovation that tipped the scales – and history – in favor of internal combustion over electric cars of the era and helped lead to the combustion engine’s dominance to this day.
While Tesla may have established its role as the industry’s electric car innovator, that’s not to say that legacy automakers haven’t made tremendous progress. GM’s short-lived EV1 electric car of the 1990s proved that exciting and fun electric cars were possible, but not necessarily affordable to make at the time. The technologies developed by GM through the EV1 program live on to this day with evolutionary electric-drive technology found in its acclaimed Chevrolet Bolt EV and other electrified models. Advanced battery electric production vehicles have also been a focus at Audi, BMW, Ford, Honda, Hyundai, Jaguar, Kia, Mercedes-Benz, Nissan, Smart, and VW, with others like Porsche set to enter the market with long-range battery EVs.
So here’s the lesson of the day: If a business model no longer works, as was the case with General Motors and Chrysler during the financial meltdown in the late 1990s, you restructure. A brand no longer resonates with consumers? You drop it, like GM did with Oldsmobile. And if a class of vehicles is falling out of favor in lieu of more desired ones, you move on, as Ford is doing by phasing out almost all of its passenger cars in coming years in favor of more desired crossover/SUVs and pickups.
A paradigm shift is also occurring as automakers grapple with changing consumer preferences, regulatory requirements, and the projected demand for future vehicles and technologies. Enter the age of electrification. Over the past decade, Tesla has set the bar for innovative battery electric propulsion, advancements in near-autonomous driving technology, over-the-air vehicle software updates, and more. It has achieved a real or perceived leadership position in these areas and that’s a threat to legacy automakers. Now automakers are responding in a serious way and Tesla itself is under siege.
GM fired the first volley with its 2017 Bolt EV, beating Tesla’s long-touted Model 3 to market with an affordable long-range EV capable of traveling 238 miles on battery power. While Tesla is now delivering its well-received Model 3 in increasing numbers after a series of production challenges, the race with GM to produce an ‘affordable’ mainstream EV with 200-plus mile range was not much of a race to affordability at all. GM won that one handily, holding the line with a $37,500 price (after destination charges), while Tesla’s $35,000 Model 3 has yet to materialize. As Tesla did with its earlier model launches, the automaker is delivering uplevel, high-content, and higher-performance versions first, in the case of the Model 3 from a recently-lowered base price of $42,900 to $60,900, depending on configuration. The Bolt EV’s MSRP has moved in the other direction, dropping slightly to $36,620 for the 2019 model.
Nissan’s all-new, next-generation LEAF that debuted in 2018 improved its range to 150 miles, with a recently-announced LEAF PLUS model joining the lineup with a bigger battery and a range of 226 miles. Hyundai’s 2019 Kona Electric and Kia’s 2019 Niro Electric offer a battery range of about 250 miles, although these offer availability only in California and perhaps a few other ‘green’ states.
Jaguar’s 2019 I-PACE, a fast and sporty crossover with a 234 mile battery electric range, is now available and priced to compete with Tesla’s Model S and X. We'll soon be seeing Audi e-tron and Porsche Taycan long-range electrics on U.S. highways, with others like Aston Martin and Maserati developing high-end electric models as well.
It will be interesting to see how this all plays out over the coming months and years. To be sure, legacy automakers will not cede their leadership positions and market share without a terrific fight… and that fight is intensifying. Tesla doesn’t fear risk and has shown it will go in new directions that others will not, unless they must.
But Tesla doesn’t operate like legacy automakers that have been around for a long time, some more than a century. Those companies have mastered mass production, fielded extensive model lineups, developed widespread and convenient service networks, and have a history of successful worldwide distribution. Tesla is still learning this game, although it is making headway with its intense and successful efforts to deliver increasing numbers of its Model 3 to customers.
Importantly, legacy automakers are immensely profitable, while Tesla has had but a few profitable quarters since its launch and its losses have been in the billions. Tesla’s well-documented difficulties in ramping up mass production of the company’s 'entry-level' Model 3 – and its initial deliveries of only up-level Model 3 examples at significantly higher cost than its widely-publicized $35,000 base price – have added to its challenges.
That said, it would be a mistake to count Tesla out for the long haul based on its current and historic challenges including missed financial and vehicle delivery targets, serious Model 3 production challenges, and a number of high-profile Tesla crashes while driving on its much-touted Autopilot. Regardless of all this, in 2018 Tesla’s Model 3 was the best-selling luxury model in the U.S.
Legacy automakers will have Tesla directly in their sights and Tesla will continue to innovate. A veritable race-to-the-finish!
Volvo’s smallest crossover features an aggressive design that’s a bit of a departure for the automaker, even as it retains the fundamental styling cues that say ‘Volvo.’ The first model built on the automaker’s Compact Modular Architecture, the new XC40 is offered as either a T4 front-wheel drive or T5 all-wheel drive and in three trim levels. The XC40 looks deceptively small but has plenty of cargo and passenger capacity for longer trips. A plug-in hybrid and possibly an all-electric model are likely in the future.
Inside, the stylish cabin aims for an uncluttered look while still providing all the amenities SUV buyers desire. Functionality is a top priority, which the XC40 provides in intelligent ways with features like spacious door bins that accommodate a laptop or tablet, easily accessible under-seat drawers for stashing wallets or other necessities, and even a trash bin for cleaning up clutter. The front storage compartment holds a wireless charge pad for smartphones. Other welcome features include a standard 9-inch Sensus Connect touchscreen and an available panoramic sunroof that provides loads of available light.
All XC40s are powered by a 2.0-liter, turbocharged four-cylinder Drive-E engine. In the T4 this engine is rated at 187 horsepower and 221 lb-ft torque. Engine output increases to 248 horsepower and 258 lb-ft torque in the all-wheel drive T5. Both connect to an eight-speed automatic transmission. Manual gear shifts are possible with the Volvo’s shift lever or, alternatively, via steering wheel shift paddles on the R-Design model.
Standard on all XC40s are Automated Emergency Braking with Pedestrian Detection, Forward-Collision Warning, Lane-Keeping Assist with Lane-Departure Warning, Automatic High-Beam Headlamps, Driver-Attention Monitor, and Traffic-Sign Detection. A self-parking feature, front and rear parking sensors, and Blind-Spot Monitoring with Rear Cross-Traffic Alert can be added as part of the Vision package.
Volvo offers Pilot Assist as a part of a Premium package. This is essentially adaptive cruise control with a semi-autonomous driving mode. It keeps the XC40 within its own lane and maintains a set speed and distance behind the vehicle ahead. Unlike some other near-self-driving systems, Pilot Assist requires the driver to keep his hands on the steering wheel at all times…perhaps not a surprise considering Volvo’s longstanding focus on safety.
The 2019 XC40 serves up 23 city and 33 highway mpg, at a starting cost of $33,700. Another option is Care by Volvo, an innovative subscription service that includes use of a new XC40 Momentum ($600 per month) or R-Design ($700 per month) for a maximum of 15,000 miles per year. Insurance, maintenance, and road-hazard protection are included, plus the opportunity for the lessee to upgrade to a new XC40 each year for the same all-inclusive monthly payment. A subscription lasts for 24 months.
In today's all-cars-look- alike world, the Cadillac’s 2019 XT4 takes exception. This upscale compact crossover features distinct features like sharp angles, a wide mesh-textured grill with a floating wreath and crest, prominent standard LED daytime running lights, plus unique headlights and large vertical taillights that will not be mistaken for another brand. The XT4 comes in Luxury, Premium Luxury, and Sport trims. The Sport trim gets a black mesh grille, body-color door handles, and black window trim, features that are chrome on other trims.
The XT4 is the first Cadillac to be powered by the brand’s new 2.0-liter turbocharged 4-cylinder, which uses what Cadillac calls a ‘tripower’ system featuring variable valve lift and cylinder deactivation. The smooth and refined engine produces 237 horsepower and 258 lb-ft torque, so this four-cylinder is quite capable of handling the two-ton XT4. A nine-speed automatic transmission is standard. It achieves an EPA estimated 30 highway mpg.
An available twin-clutch, all-wheel-drive system like that used on the XT5 is able to decouple the rear axle to improve fuel economy. This part-time all-wheel-drive system requires a double tap on a button to activate. Electro-hydraulically assisted brakes also help fuel efficiency by reducing parasitic losses from one crankshaft-driven belt. EPA numbers are 24 city and 30 highway with front-wheel-drive and 22 city, 29 highway mpg with all-wheel drive.
Optional Sport trim gets an Active Sport Suspension with adaptive dampers that react quickly to road conditions without being too stiff. The other models retain struts up front and a multilink setup at the rear. Eighteen inch wheels are standard, with 20 inch wheels optional on Premium Luxury and Sport trims, each with their own design.
Standard equipment includes blind-spot monitors, a rearview camera, and traction control systems. Optional are forward-collision warning with low- and high-speed automatic emergency braking, adaptive cruise control, automatic headlights, active lane control, and reverse automatic braking. A surround-view camera system, automatic parking assist, and a camera-based rearview mirror are also available. Cadillac’s highly advanced SuperCruise driver-assistance features are not offered on the XT4.
The XT4’s dash is dominated by an 8-inch touchscreen for infotainment and features Apple CarPlay and Android Auto compatibility. Cadillac’s CUE interface for its infotainment system adds a new dial-type controller. A near-field communication system simplifies the process of phone pairing, while wireless inductive charging pads boast faster charge times. The XT4 has 22.5 cubic feet of cargo room with both rows of seats in place. The back seat folds down for 48.9 cubic feet of storage.
The cost of entry for the base Luxury XT4 is $34,795, with the Luxury AWD trim level beginning at $37,295 and the Sport at $39.295.
The technology sector of the auto industry is advancing at a rapid pace. So fast, in fact, that if you blink something might be missed. New high-tech features are a key selling point in many higher-end or luxury vehicles today. It’s only logical that these new technologies launch in more expensive vehicles, because they are costly to engineer, develop, and produce. Premium platforms can more readily absorb the higher costs because they have greater profit margins.
That said, many of the advanced systems that were new to market just a year or two ago are working their way into more mainstream models. It’s simply the natural evolution of the car market. Coincidentally, many of these sophisticated on-board systems are now standard or optional features in electric, hybrid, and plug-in hybrid vehicles. Some of the latest electronic wizardry is targeting future autonomous transportation, or at least partial autonomous mobility. We are already seeing the first steps today. Some current production models feature automatic emergency braking to avoid an imminent collision or warn s driver if their car is drifting out of their lane. Some driver assistance systems also provide gentle steering input to keep a car centered in its lane if drifting occurs when a turn signal is not engaged.
Self-parking technology allows vehicles to parallel or head-in park without a driver touching the steering wheel, accelerator, or brakes. To accomplish this, a vehicle is equipped with sensors in the front, rear, and on the sides to determine distances to nearby objects. With that information, a car’s on-board computer can provide accurate control inputs to accomplish the parking sequence. Parking is done efficiently on the first shot, clearing the lane while saving both time and fuel.
The evolution of adding exterior cameras on vehicles began with rear-facing backup cameras. These transmit a real-time rear view to a dash-mounted display, allowing a driver to more accurately see what’s behind the vehicle. This very useful technology has filtered down to just about any car or truck with an LCD display. More advanced systems show the path a vehicle will take as the steering wheel is turned.
That was just the beginning. Cameras now proliferate in other locations on vehicles as well. The latest development places cameras on the sides of a vehicle, with some integrating eight cameras placed all around the vehicle perimeter. These provide information used in lane departure mitigation by reading lane markers and other side threats. When a lane departure is detected without a turn signal, some manufacturers alert a driver audibly and visually while others vibrate or pulse the steering wheel or seat to get a driver’s attention.
Another advantage of having cameras mounted all around the vehicle is the ability to show a birds-eye view of a car or truck on its LCD display. All camera views are stitched together to provide what can best be described as an image from a drone hovering above the vehicle. A top view image of the vehicle is superimposed in the middle. This takes back-up camera safety to a whole new level since a driver can check for pedestrians, small children, and other obstructions that might otherwise be missed from the driver’s seat. It is especially helpful in taller vehicles like trucks and SUVs.
Enabling much of the latest technology is the proliferation of LCD screens in the dash. Most of these displays are touch screen, providing increased control over various electronic functions. The goal is to provide the information and interface without it becoming a distraction to the driver, so eyes and attention aren’t diverted from the road for too long. To solve this, many systems now have a voice interface that allows the driver to push a steering wheel-mounted button and tell the car what they would like it to do, much like Apple’s Siri.
Of course, one of the first electronic functions to be integrated into LCD displays was GPS navigation. This handy function assists in driving more efficiently by suggesting the most direct or quickest route, thereby saving fuel. We’re all familiar with the way these systems adjust on the fly, redirecting a driver if you wander from the designated route by providing audible navigation prompts for getting back on track. This intelligent operation means eyes can stay on the road, an operating strategy that other ‘smart’ on-board systems would be wise to follow. Electric cars and plug-in hybrids can also find the nearest public charging station using most nav systems, a handy thing if you are driving in unfamiliar territory.
Traction control, a system that detects drive wheel spin and adjusts power and braking accordingly to keep a vehicle moving forward, has been with us for many years now. While not connected to the road in the ‘smart’ sense like the newest driver assist technologies, manufacturers are taking this concept another step with vehicle rotation and wheel speed sensors at all four wheels to keep the vehicle from spinning-out and losing control. Though there are different names for this technology, it is commonly referred to as yaw control since it detects rotation of the vehicle and applies power or braking to individual wheels as needed, thus preventing the potential for spin.
Technologies facilitating communication between vehicles and the surrounding environment hold great promise and are already being deployed to a degree. With car-to-car interaction, a driver could be alerted in advance to slippery conditions if a car ahead experiences wheel slip or traction control is activated. Two-way communication between vehicles can also be used to warn of road hazards, or by emergency vehicles to alert nearby drivers to proceed with caution or give way.
One of the most useful technologies to come out in the past few years is adaptive cruise control. This feature gauges distance to the vehicle in front when cruise control is set. If that vehicle is going slower than the set cruise speed in your vehicle, cruise speed will be reduced to match the vehicle ahead and keep a safe distance. Adaptive cruise control systems typically allow a driver to select the distance they feel is safe. Most systems will also bring your car to a complete stop and apply braking if necessary to avoid a collision or an object in the road.
This is made possible by the integration of forward-facing radar. The radar sends a signal out that bounces off vehicles or objects and is returned to the vehicle’s receiver. An on-board computer then calculates distance and closing speed to determine what appropriate actions are required. More advanced adaptive cruise control detection incorporates LIDAR (Light Detection and Ranging). LIDAR works much like radar but uses lasers to read distance.
In the not-too-distant future, cars will communicate with smart city infrastructures in addition to other vehicles on the road. Greater use of cellular signals for this communication plus satellite information will also be required. Work on this front is already well underway as it will be necessary for implementing both semi- and fully-autonomous vehicle operation.
All of this new and future connected technology requires considerable computing power inside the vehicle, which will add weight and require a very stout electrical system. The connected car trend has considerable momentum and is sure to advance at a rapid pace in the future. So don’t blink…or you may well mist the next big breakthrough in this fast-paced field!
Our drive of the 2019 Lexus ES 300h, the hybrid variant of this automaker’s all-new, seventh-generation ES sedan, was accommodating as expected from this luxury brand with welcome performance. During our drives we found turn-in sharp and precise. Considering front-to-rear weight distribution is heavy over the front wheels, the suspension compensates well and the car feels well-balanced.
Built on Lexus’ new Global Architecture-K platform, the ES enjoys a 2.6-inch increase in length, 1.8-inch increase in width, and wider front and rear tracks compared to the model it replaces. It also offers a two-inch longer wheelbase at 113 inches and a more spacious rear compartment.
The luxury sedan’s most striking angle is its profile that shows low hood and roof lines. From the front it’s the automaker’s unmistakable spindle grill that dominates, enhanced by slim L-shaped LED projector headlights.
The ES 300h layout is front engine, front wheel drive with power derived from a 2.5-liter 4-cylinder engine, plus an electric motor mated to an all new hybrid transaxle. This delivers 215 total system horsepower. A six-speed automatic transmission with paddle shifters is electronically controlled and continuously variable.
Powering the electric motor is a nickel-metal-hydride battery that's more power dense and compact than its predecessor, allowing it to be relocated from the trunk to beneath the rear seat, thus adding welcome trunk space. This fourth-generation Hybrid Drive System enables accelerating from 0-60 mph in 8.1 seconds and provides a nearly 600-mile driving range, plus excellent combined 44 mpg fuel economy.
Inside is a well-appointed cabin that’s tranquil and free of exterior noise. New suction-type ventilated cooling seats kept us as comfortable and entertained as any in the new movie theaters. There are lots of choices for interior personalization with three color schemes available, four trims, and three material options for the seats. The car’s standard audio has 10 speakers, and to please audiophiles there’s the optional Mark Levinson audio with 1800 watts and 17 speakers.
Of course, the ES 300h offers all the latest driver assistance systems plus an array of convenience features like Apple CarPlay, and it will be Amazon Alexa-enabled for Android phones and iPhones. Outstanding fuel consumption, a striking design, and first-class amenities make the new Lexus ES 300h a real contender for today’s premium car buyers.
The price of entry for the conventionally powered 2019 Lexus ES is $39,500, with the ES 300h hybrid just $1,810 more at $41,310.
Green Car Journal’s 2019 Green Truck of the Year™, the new RAM 1500, is lighter, more efficient, and higher tech than ever. Of special interest is that the RAM integrates electrification for increased efficiency by offering two mild hybrid powertrains, exclusive to the segment. It features more hauling and towing capacity than the generation before it, with the ability to tow up to 12,750 pounds and carry a payload of up to 2,320 pounds. RAM 1500 rides on a wheelbase about four inches longer with a larger cab. Efficiency has been enhanced by shedding up to 225 pounds through the use of high-strength steel, aluminum, and composites.
RAM 1500 is offered in four-door quad cab and crew-cab body styles, with 67.4- and 76.3-inch beds, and in seven trim levels. Three headlamp variations are available including Halogen, full LED, and an all-new full LED adaptive front-lighting system. A robust 4x4 off-road package is available. The pickup’s most notable exterior feature is its new grille, which replaces the RAM’s iconic grille that’s been used since the Dodge days.
Contributing to the RAM 1500’s aerodynamic efficiency are grille shutters that help smooth airflow and a front air dam that automatically lowers by 2.5 inches at speeds above 35 mph. A new venturi roof design directs air back to the rear spoiler. Bed rails raised by 1.5 inches and a new spoiler on the aluminum tailgate reduce drag. A lockable tri-fold tonneau cover improves fuel economy while adding security and weather protection. The RAM’s optional air suspension system lowers the truck 0.6 inches at speed to further improve aerodynamics.
Power is delivered by a 305 hp 3.6-liter V-6 or 395 hp 5.7-liter HEMI V-8, each mated to a new TorqueFlite eight-speed automatic transmission. A new-for-2019 eTorque mild hybrid system replaces the RAM 1500’s alternator with a motor/generator that uses regenerative braking to charge a lithium-ion battery pack Standard on V-6 and optional on V-8 engines, eTorque provides stop-start operation and a brief torque boost of 90 lb-ft in V-6 RAMs and 130 lb-ft in V-8 models. An interactive deceleration fuel shut off system also saves fuel.
Among the RAM 1500’s advanced technologies is a fourth-generation Uconnect system and 12-inch, fully reconfigurable touchscreen display. SiriusXM Guardian Connected Services delivers advanced in-vehicle connected services including a 4G Wi-Fi hotspot. Android Auto and Apple CarPlay are standard.
An available 360-degree surround view camera system provides a birds-eye view via four cameras positioned around the vehicle. Uconnect 4 with an 8.4-inch display and Uconnect 3 with 5-inch display are also offered. Driver assist systems include forward collision warning, advance brake assist, blind-spot monitoring and lane departure warning, and adaptive cruise control with stop, go, and hold. SiriusXM Traffic/Travel Link is available.
There’s a lot of talk these days about self-driving cars and their place in our driving future. While we are likely to see autonomous vehicles plying our highways in the years ahead, in the meantime many of the advanced technologies integral to self-driving cars are available in vehicles you can buy today, making them smarter and safer. Focusing on accident prevention and driver convenience, their appearance is usually in higher-end vehicles first before they filter down to more affordable models, driven by popularity, major cost reductions, and government mandates. Fortunately, many new capabilities can be added easily by writing software that uses sensors, cameras, and other hardware already installed on a vehicle. Automakers can use the Internet of Things (IoT) to add this software over the air without requiring owners to take vehicles back to the dealer, just like Windows and Apple update your computer and smartphone. Yes, it’s a brave new world.
DRIVER DROWSINESS DETECTION helps prevent accidents. Fatigue can be measured by monitoring eye activity, changes in driving style determined by steering input, or a lane departure alert system showing a driver is often drifting from his lane. In more sophisticated systems drowsiness could be identified with sensors monitoring brain activity, heart rate, skin conductance, or muscle activity. A visual or audible warning may be issued or the driver’s seat may vibrate. More sophisticated monitoring techniques may also detect a medical emergency and call 911.
BLIND ZONE ALERT systems typically use radar or ultrasonic sensors on both sides of the vehicle to “look” for cars, trucks, and motorcycles in side blind zones. These systems alert a driver with a flashing light in the side view mirrors and often with an audible sound or vibration of the steering wheel. If the turn signal in not activated to indicate you’re planning to change lanes, the mirror warning light glows to show there’s a vehicle in your blind spot but does not flash.
ADAPTIVE CRUISE CONTROL augments a vehicle’s standard cruise control system to enhance safety. Once selected, it automatically adjusts vehicle speed to maintain a safe distance from vehicles ahead. The system’s radar, laser sensors, and/or cameras detect if you will be overtaking a vehicle in the lane ahead and automatically slows your speed if necessary. Your set cruise control speed resumes when traffic ahead allows.
COLLISION AVOIDANCE SYSTEMS can prevent or reduce the severity of a collision by using cameras, radar, and sometimes LIDAR to detect an imminent crash. Once detected, the system provides a warning if a collision is imminent and can autonomously activate braking or steering, or both. If a driver does not react to a warning, the system pre-charges brakes and increases brake assist sensitivity to maximize braking performance. Most manufacturers plan to include automatic emergency braking as standard equipment on cars in the U.S. by 2022.
LANE DEPARTURE ALERT uses a specialized camera to detect painted lane markings and alert a driver that inadvertently strays out of their lane. An audible warning and indicator light on the instrument panel is typically used to warn wayward drivers, and sometimes a steering wheel vibration. In more sophisticated systems, Steering Assist will initiate corrective steering to help keep the vehicle in its lane if a driver does not take corrective action.
OBSTACLE AVOIDANCE SYSTEMS scan the road ahead with radar, ultrasonic sensors, and/or cameras for pedestrians, motorcycles, large animals, or other objects that are stopped or moving slowly. Initially, visual and audio warnings are given when a potential collision is detected by the sensors. If necessary, automated steering and braking maneuvers the vehicle to avoid a collision.
ANTICIPATING THE ROAD AHEAD is possible with GPS navigation data integrated with on-board systems. For example, navigation data can be used to control a transmission or set up suspension for a winding road ahead, or adjust for sporty driving, fuel economy, or comfort. In plug-in vehicles data can be used to identify sections of a route best suited for electric drive or for charging the battery.
REAL TIME TRAFFIC INFORMATION supplied by a traffic information service identifies accidents and other traffic delays by presenting this information on a navigation screen. The navigation system can calculate and recommend alternate routes to a destination that bypass the location causing a delay.
PARKING ASSIST enables hands-off automated parallel and often also perpendicular parking by controlling throttle, steering, and braking. The system scans to assure there is sufficient space and often locates vacant parking spots. Advanced systems may work with a real-time traffic information system to predict the odds of finding an open parking spot in a particular area, since looking for a parking space is a major contributor to traffic congestion in urban areas.
PRE-SENSE SYSTEMS detect potentially unavoidable crashes with sensors from electronic stability and collision avoidance systems, blind spot detection, adaptive cruise control, and rear cameras. A pre-sense event occurs in phases with a visual and/or audible warning so the driver can take evasive action, then brief automatic braking tells a driver to apply braking with brake assist enhancing deceleration. If a collision can’t be avoided maximum braking is applied, seat belts are pre-tensioned, hazard lights are activated, windows are closed, and airbags deployed to mitigate injuries.
REMOTE PARK ASSIST allows your car to autonomously park in a tight spot or a narrow garage. With this system, driver and passengers exit the vehicle once it is aligned with a parking spot. The vehicle is then slowly and autonomously moved forward using a remote control fob or smartphone. This capability is made possible by surround-view sensors that enable precise movement and positioning of the vehicle amid other cars or objects, using the same sensors and controls as those used by more familiar parallel and perpendicular park assist systems. Once parked, the car can also be turned off and locked remotely. The process is reversed to fetch the car when you want to leave.
VEHICLE-TO-VEHICLE COMMUNICATION allows vehicles to “talk” with one another to exchange information like speed and GPS-derived location. The main benefit is accident avoidance, but once implemented this sophisticated network could also reduce traffic congestion. Vehicles share safety data 10 times per second to identify risks and provide warnings to avoid crashes. This kind of information can inform a driver in advance whether it is safe to pass on a two-lane road, make a left turn across the path of oncoming traffic, or if a vehicle is approaching at a blind intersection. Vehicle-to-infrastructure communication enables the transfer of data between vehicles and elements of the roadway infrastructure including speed limits and traffic lights. With advanced V2V and V2I systems, vehicles could autonomously take necessary actions to avoid a potentially serious incident or collision.
