Chevrolet’s exciting new Corvette E-Ray marks several important milestones for the marque, most notably the Corvette’s first application of hybrid technology and its first use of all-wheel-drive. It’s also expected to be the quickest Corvette ever with projected 0-60 acceleration in just 2.5 seconds. The E-Ray will be replacing the Gran Sport trim option in the Corvette lineup, with Chevrolet offering three trim levels for the E-Ray including the entry-level 1LZ, mid-range 2LZ, and top-line 3LZ.
The E-Ray will use Chevrolet’s 6.2-liter LT2 crossplane crankshaft V-8 producing 495 horsepower and 470 lb-ft torque. The midship LT2 is augmented by a magnesium and carbon fiber-encased 160 horsepower electric motor mounted at the front, with energy supplied by a 1.9 kWh lithium-ion battery. The E-Ray’s combined 655 horsepower and 595 lb-ft torque is channeled through a Tremec eight-speed dual clutch automatic transmission. All this provides enough muscle to earn the E-Ray a quarter-mile time of 10.5 seconds at 130 mph.
Handling all this muscle is well-covered. Brembo Carbon-Ceramic brakes and Chevrolet’s Magnetic Ride Control 4.0 are standard equipment, along with staggered 20-inch front and 21-inch rear wheels employing wide, Z-rated all-season tires. Chevrolet also gives drivers plenty of options when it comes to applying the E-Ray’s lean and green power with six selectable driving modes. These include Tour, Sport, Track, Weather, My Mode, and Z-Mode.
Plenty of sustainable and eco-friendly functions are also built in. Active Fuel Management allows the LT2 V-8 to shut down half its cylinders during times of low power demand to conserve fuel. Drivers can select a Charge+ mode to maximize battery life when high performance is not needed. An E-Ray-specific Stealth Mode is also standard that enables driving silently on battery power up to 45 mph for limited distances, a welcome function for drivers and neighbors alike.
A Corvette is meant to look lean as well as quick, and the E-Ray is no exception. The E-Ray’s front end retains the C8 Corvette look, with a couple of unique styling cues. A body-colored grille surround is present around the wide-mouthed opening, along with a pair of large and functional air induction ports sitting beneath chiseled, aggressive headlights. The classic Fleur-De-Lis emblem, synonymous with the Corvette name since its introduction in 1953, is seen center stage.
At both sides of the E-Ray are a pair of imposing side scoops that guide air over the rear wheels to enhance better grip. These side scoops are outlined with a three-pronged, gloss black design that’s yet another styling cue unique to the E-Ray. Aggressive haunches sit atop both the front and rear wheels, a look that is ironically Corvette.
Looking rearward, those wide haunches slope back into the E-Rays slightly pointed rear end and impart a familiar and decidedly athletic look. A pair of functional air exit ports sitting above a quad-tailpipe exhaust system are surrounded by a large, race-inspired rear air diffuser finished in gloss black. Looking down through the rear window allows viewing the LT2 V-8 on full display.
Inside is an interior designed to completely immerse occupants in the driving experience. A squared, Formula 1-inspired carbon fiber steering wheel sits in front of the driver with an 8-inch infotainment screen angled directly towards the driver’s position. A 12-inch digital gauge cluster in front of the wheel displays the usual functions along with battery life and torque readings unique to the E-Ray. A large pillar angling downward from the dash features climate and seat warmer controls, among others. Twin stitching and tone-on-tone colors are used throughout the passenger space, along with carbon fiber-accented seatbacks. Chevrolet made sure to include a front trunk, or frunk, seen on regular C8 models as research indicated it was an important feature for prospective E-Ray buyers.
The E-Ray contains plenty of brains to go along with all its brawn. Chevrolet’s Infotainment 3 Plus system is present, offering Bluetooth audio streaming and wireless CarPlay and Android Auto capability.
Chevrolet’s Corvette E-Ray is a very big deal for the performance automotive world. It is the first hybrid V-8 sports car made domestically for the consumer market, as well as the quickest Corvette ever produced. All eyes will be on the E-Ray, and time will tell if it can live up to the hype. Pricing starts at $104,295 for the 1LZ coupe version, with deliveries of the E-Ray expected to begin in late 2023.
Everyone is familiar with Tesla these days. In its early years, though, Tesla was just another aspiring automaker with big dreams and enormous challenges, and at times, seemingly insurmountable financial hurdles. That’s all changed and Tesla is now viewed as a serious competitor by the world’s legacy automakers. Today there’s the Tesla Model 3, Model S, Model X, Model Y, and Tesla Semi. Coming up will be a second-generation Tesla Roadster and Tesla's highly-anticipated Cybertruck. Sixteen years ago, Green Car Journal featured the company’s original electric Roadster and shared the emergence of Tesla as a potential competitor in the electric vehicle field. We present this article just as it ran in Green Car Journal’s Fall 2006 issue to lend context to the ever-unfolding Tesla story.
Excerpted from Fall 2006 issue: Only giant corporations have the resources to develop competent, competitive automobiles, and only internal combustion-powered cars offer the performance and practicality required by today’s drivers. The team at Tesla Motors is tasked with turning these conventions onto their respective heads…and they’re doing it.
From its founding in 2003, most of the company’s efforts have gone into developing the heart of the car, the Energy Storage System (ESS). Some 6,831 lithium-ion cells – each slightly larger than a typical AA battery – are contained inside a large enclosure that fits neatly behind the Roadster’s two seats. The batteries are liquid cooled and attached to an elaborate array of sensors and microprocessors that maintain charge balance between the cells. Tesla chose a commonly used lithium-ion cell so that battery development will continue to drive down the cost and improve performance.
Also developed internally is the motor, which features remarkably high output for its small size: 248 hp and 180 lbs-ft of torque. The motor acts as a generator whenever the driver lifts off the throttle, providing an ‘engine braking’ effect similar to conventional cars, while also recharging the batteries.
The Roadster’s chassis is based on that of the Lotus Elise sports car, but lengthened and beefed up to handle the Roadster’s roughly 350 pounds of extra weight, largely attributable to the battery pack. The body design was penned by the Lotus Design Studio, and final assembly is completed at the Lotus manufacturing facility in England.
Along with a top speed of 130 mph, the company claims a zero to 60 mph time of four seconds, on par with some of the world’s top supercars. But the real test for an electric car is range. Tesla says the batteries will last for 250 miles of pure highway driving, and can be recharged using Tesla’s home-based charging system in under four hours. The batteries are expected to last five years or 100,000 miles, after which time they’ll have 80 percent of their original capacity. In terms of real-world practicality, these are some of the most impressive numbers we’ve seen from an electric car.
There’s one more crucial number: price. The Tesla Roadster starts at $89,000 and tops out at $100,000. That’s steep, but not wholly unrealistic given the level of performance the car achieves.
Tesla Motors thinks there’s plenty of demand for their car, and early signs look good: the first 100 Roadsters were snapped up right away. It will be interesting to see if that kind of buying fervor continues as Tesla opens its direct sales and service centers, first in Northern and Southern California, followed by Chicago, New York, and Miami. The company begins the first production run of 600 to 800 cars next spring, maxing out at 2500 per year after three years if demand holds.
Plans are already in the works for the next model, a 4-door sedan in the vein of Toyota’s Prius. Tesla’s Mike Harrigan thinks that in five to six years, the cost of batteries will have been cut in half – the Roadster’s pack costs about $25,000 today – and will be capable of providing a family sedan with a range of 500 miles, double that of the Roadster.
The Tesla Roadster may be the perfect weapon to launch the Tesla brand. It’s eye-catching and fast and targeted at a segment that can realistically command high prices, thereby helping to absorb the high cost of the batteries and high-tech control system. The next step, and perhaps the greater challenge, is to drive this high concept down to the mainstream. We’ll be watching intently.
Part of Honda’s Clarity triple-play – along with the hydrogen-powered Clarity Fuel Cell and more mainstream Clarity Plug-In Hybrid – the Clarity Electric is a model that clearly cuts its own path.
It does not aim to be part of the ‘200 mile club,’ the latest generation of uber-electrics that claim a battery electric driving range greater than 200 miles between charges. It also does not cultivate efficiencies through a compact form designed to eke the most from every electron. Nor is it exceptionally lightweight, another common nod to the need for making the most of the battery power carried on board. In fact, there is little about the Clarity Electric that makes us think of other all-electric vehicles…save for the fact that it runs exclusively on zero-emission battery power, of course. This mid-size, five-passenger battery electric vehicle aims to be in a league of its own.
First of all, let’s discuss driving range, which is EPA rated at 89 miles between charges while delivering a combined 114 MPGe (miles-per-gallon equivalent). Yes, that’s more limiting than that of the 200+ mile club, but there’s a reason. Honda designed the Clarity Electric with the needs of commuters in mind…those who want their daily drive to be in a highly-efficient, zero-emission electric car with a sophisticated look and premium feel. And they designed it so it was significantly more affordable than premium competitors offering higher-end electric models with features similar to those of the Clarity. Currently, the Clarity Electric is offered at a $199 monthly lease in California and Oregon where this battery-powered model is available.
Honda figures that an approach focused on commuters is a sweet spot for the Clarity Electric. Its range fits the needs of most commutes and its price is certainly justifiable for a commuter car, and a luxurious one at that, with fuel costs substantially less than conventionally-powered models. Plus, most households have two cars at their disposal, sometimes more. Having a Clarity Electric as a primary commuter car with a conventional gasoline or hybrid vehicle also in a household’s stable covers all bases.
Honda gave a lot of thought to the cabin design with welcome touches throughout. We especially like the ‘floating’ design of the center console with its array of integrated controls and flat storage tray beneath, with 12-volt and USB outlets. The dash features a handsome suede-like material and an 8-inch touchscreen display elegantly integrated into the dash. Deep cupholders feature flip-up stays for holding smaller drinks. Side door pockets are large enough to accommodate water bottles. The trunk offers plenty of room and is illuminated when the trunk lid is remotely or manually unlatched. At night this allows you to immediately note what’s inside through the trunk lid’s clear back panel before opening…something we’ve really come to appreciate over time.
Driving the Clarity Electric is a satisfying experience, with this sedan both well-mannered and responsive. Power is delivered by a 161 horsepower electric motor energized by a 25.5 kWh lithium-ion battery that can be charged in about three hours with a 240 volt charger, or in as little as 30 minutes with a public DC fast-charge system to an 80 percent state-of-charge. While its primary job may well be to handle everyday driving needs and negotiate traffic, it also delivers plenty of fun on twisty canyon roads with flat cornering and confident steering. It’s quick, like almost all electrics are because of instant torque delivered at launch, providing very satisfying acceleration.
Also appreciated is the Clarity’s handy Apple CarPlay integration and its Honda Sensing suite of driver-assist technologies. Among these are important features like adaptive cruise control with low-speed follow, forward collision warning, collision mitigation braking, lane departure warning, and road departure mitigation.
The Clarity Electric has served us well on our daily drives over the course of Green Car Journal’s ongoing long-term test. Its use supports what Honda envisioned for this efficient electric car. It has been ideal for around-town duty, area trips within its range, and daily commutes. Its thoughtful and sophisticated – dare we say futuristic – design and very satisfying drive experience are appreciated every day we’re behind the wheel.
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.
Toyota is now selling its all-new RAV4 EV at select California dealerships. This all-electric SUV was jointly developed by Toyota and Tesla Motors, combining a Tesla designed and produced battery and electric powertrain with Toyota’s most popular SUV model. No interior space was lost due to EV components
Our editors who have driven the RAV4 EV have found it to be an excellent small SUV that performs seamlessly, with an intelligent approach to electric motoring. You’re not left wanting for power, comfort, or the kind of driving experience expected of a Toyota product…it’s all there, but without the inherent drawbacks of burning gasoline. At nearly fifty grand, though, it’s likely not for everyone.
The RAV4 EV’s 154-horsepower AC induction motor drives the front wheels via a fixed-gear, open-differential transaxle. There are two drive modes, ‘Sport’ and ‘Normal.’ In the Sport mode with 273 lb-ft of peak torque brought to bear, the vehicle reaches 0-60 mph in 7.0 seconds and has a top speed of 100 mph. In the Normal mode with 218 lb-ft at the ready, acceleration to 60 mph takes 8.6 seconds and top speed is 85 mph.
Its liquid-cooled lithium-ion battery is a first for Toyota. Battery thermal management systems provide consistent performance in a variety of climates. The battery pack is mounted low and to the center of the vehicle, contributing to a more sedan-like ride. Two charge modes are available, with a Standard Mode charging up to 35 kilowatt-hours for an EPA-estimated range rating of 92 miles, optimizing battery life over range. An Extended Mode charges the battery to its full capacity of 41.8 kilowatt-hours to provide an anticipated range of 113 miles. The battery is warranted for eight years or 100,000 miles.
A drag coefficient of 0.30, the lowest of any SUV in the world, is an improvement over the conventional gas powered RAV4’s Cd of 0.35. To achieve this, Toyota restyled the front bumper, upper and lower grill, side mirrors, rear spoiler, and underbody design to optimize air flow. The Toyota/Tesla designed regenerative braking system increases driving range by up to 20 percent. A tire repair kit replaces the spare to reduce weight.
An innovative climate control system offers three modes. In the NORMAL mode, it operates just like that of a conventional vehicle for maximum comfort, drawing the most power and resulting in the least range. The ECO LO mode balances comfort with improved range through reduced power consumption by the blower, air conditioning compressor, or electric heater. In cold weather, ECO LO automatically activates and controls seat heaters to optimal levels. ECO HI further reduces blower, compressor, and heater levels and also automatically activates the seat heaters as necessary. Efficiency achievements are notable. ECO LO can reduce power consumption by up to 18 percent compared with NORMAL, while ECO HI offers up to a 40 percent reduction. Remote Climate Control – set by a timer, by the navigation display, or by using a smart phone – pre-cools or pre-heats the interior while the vehicle is plugged into the grid to save on-board battery power.
Driving efficiently is assisted with an all-new instrument cluster that includes a power meter, driving range display, battery gauge, speedometer, shift indicator, and multi-information display. The latter has six screens that provide information on driving range, efficiency, trip efficiency, CO2 reduction, and ECO coach and AUX power functions. Trip efficiency displays the average power consumption in intervals of five minutes. Eco coach evaluates the level of eco-sensitive driving according to acceleration, speed, and braking and displays an overall score. CO2 reduction, displayed graphically via a growing tree, is compared to a conventional gasoline vehicle.
Premium Intellitouch Navigation features EV system screens that help maximize driving range. The EV Charging schedule lets customers schedule when the vehicle will charge and activates pre-climate conditioning based on departure time. A Range Map shows how far the car can travel on available battery charge. A Charging Station app displays nearby charging stations.
For the shortest charge time of about six hours, Leviton offers a custom 240 volt, Level 2 charger with 40 amp / 9.6 kilowatt output. The RAV4 EV comes equipped with a 120 volt Level 1 charging cable operating at 12 amps for use when the recommended Level 2 charging is not available.
The RAV4 EV comes standard with the STAR Safety System that includes enhanced vehicle stability control, traction control, anti-lock brake system, electronic brake-force distribution, brake assist, and smart stop technology. While the RAV4 EV is pricy at $49,800, that price decreases a bit since it qualifies for a $2,500 rebate through California’s Clean Vehicle Rebate Program as well as a $7,500 federal tax credit. Toyota plans to sell about 2,600 units through 2014.
