The midsize Polestar 3 SUV, the latest Polestar model to hit U.S. shores, is distinguished with sculpted styling, a minimalist interior, and loads of tech. It also features a good amount of real-world range and, living up to the automaker’s sporty performance goals, great handling and plenty of power.
The rub: The 2025 Polestar 3 starts at almost $69,000 and can edge close to $100,000 in top performance trim with all the available options. It’s not for the multitudes who live on tight budgets.
Likely rivals for shoppers’ attention include electric SUVs from the likes of Audi, BMW, Mercedes-Benz, and Volvo. You could toss in models such as the Cadillac Optiq, Tesla Model Y, and Genesis Electrified GV70, but they really play in a different segment as compact SUVs.
Polestar offers the 3 in three “long range” powertrain choices with option packages to increase the tech, driver assist and comfort, and “gee, look at me” content. The base single-motor, rear-wheel drive version delivers, per the EPA, up to 350 miles of range. None of the competing high-end electric SUVs can match that, although none offer single-motor version, opting instead for 100 percent all-wheel drive lineups.
More powerful but less efficient dual-motor, all-wheel drive versions of the Polestar 3 come in two flavors. The base dual-motor trim boasts a segment-leading 315 miles of range, per the EPA’s rating system. Adding the Performance Pack option drops the Polestar 3 Dual Motor’s rated range to between 279 and 300 miles, depending on tire and wheel size. That’s in the ballpark with the 300-mile Audi Q8 e-tron, 307-mile Mercedes-Benz EQE SUV, 309-mile BMW iX xDrive50, and 310-mile Volvo EX9.
Sizewise, the Polestar 3 sits near the bottom of it pack. While its passenger cabin is roomy, the 3 overall is as much as 5.5 inches shorter than other premium and luxury mid-size electric SUVs. It sits mid-pack in cargo capacity, though, bested by the BMW iX and Audi but leading the EQE SUV and the Volvo EX90. Pricewise, the Polestar starts lower than any likely competitor.
The Swedish EV maker started life as an independent tuning shop for Volvo racers, then was absorbed by Volvo Cars, which has been owned by China’s Zhejiang Geely Holding Group since 2010. In 2017 Geely decided it wanted a stand-along EV makers in its stable to market performance-oriented but premium-level vehicles globally. Polestar was spun off from Volvo to be that company.
It is publicly traded, but a majority of its shares are held by Geely and Geely founder and CEO Li Shufu’s private PSD Investment. Volvo Cars also holds a stake.
Polestar’s first model, the limited production Polestar 1, was a sport coupe with a 600 horsepower plug-in hybrid powertrain and 52 mile all-electric range, the best in the business. It was sold globally, though in very small numbers, from 2019 through 2021 and won praise for its styling and performance. Only about 1,500 of the $150,000 cars were built and just 250 of them made it to the U.S.
The Polestar 2, a compact sedan-styled hatchback, launched in 2019 and still is sold in Asia and Europe. U.S. sales of the sporty 2 were curtailed this year in the face of stiff tariffs on vehicles imported from China, where it is built.
Polestar 3 went on sale in the U.S. earlier this year in dual-motor trim, with the single-motor version launching in April. Models sold in the U.S. are built alongside the Volvo EX90 at Volvo’s South Carolina assembly plant. The 3 will be followed later this year by the Polestar 4, a tall sedan styled midsize SUV that shares most of its powertrain, suspension, and interior with the 3. It will be built in South Korea.
A Polestar 5 sport sedan – the brand’s new flagship model – is slated for 2026 and will be built in South Carolina and/or South Korea. The Polestar 7 compact SUV aimed mainly for the European market and slated to be assembled there is scheduled next, to be followed by the Polestar 6, a 2+2 performance roadster with head-turning design.
Don’t expect to consistently get EPA estimated range from any Polestar 3 variant unless your accelerator foot is feather light, your driving style rather timid, and you avoid hilly or mountainous terrain and highway driving. Real-world range for most EVs runs 10 to 15 percent below EPA estimates with the variance depending largely on tire size, the weight of cargo (including people) on board, driving style, terrain, and the amount of high speed driving involved. We tested both the single-motor and dual-motor performance versions of the Polestar 3. Our experience is that it manages to stick pretty close to the estimates, running 10 to 12 percent short in most driving conditions.
In in our range test of a single-motor Polestar 3 with 21-inch wheels – the variant EPA rates at 350 miles – our 250-mile round-trip ride covered 140 miles of fast freeway driving in light traffic, plus 70 miles of ambling country lanes and 40 miles of mountain roads. We tried to keep within 10 mph of posted speed limits.
Per EPA’s estimate, we should have been draining the battery pack at a rate of 3.27 miles per kilowatt-hour (350 miles/107 kWh usable battery capacity). But country and mountain driving on the first leg of the trip was uphill most of the way, cutting efficiency to just 2.4 miles per kWh. That would have resulted in just under 266 miles of range had we kept going at that pace. We benefitted from an equal amount of downhill motoring on the way back, though, and improved efficiency for that part was a relatively thrifty 3 miles per kWh. For the entire round trip, average consumption was 37.3 kWh per 100 miles. That’s the equivalent of 307 miles of range – 12.2% under the EPA estimate.
We tested the dual-motor performance version of the Polestar 3 last fall on rain-slicked roads in the area around Jackson, Wyoming. An abundance of caution with someone else’s vehicle kept speeds down, but we did climb about 2,200 feet from Jackson’s 6,240-foot elevation to hit the pass through the Tetons into neighboring Idaho. Overall, we found real range on that trip was pretty much what EPA estimated for the performance version with 22 inch tires.
All versions of the 2025 Polestar 3 are two-row, five-seat electric crossovers. There’s a lot of Volvo under the skin and in the interior, but Polestar DNA is dominant in the 3’s design and chassis, suspension, and powertrain development.
Its aerodynamic looks derive from the Polestar Precept electric sedan concept that was unveiled in 2020. It’s built on an EV-specific platform developed by Volvo.
The rear-drive Polestar 3 starts at $68,900 under pre-tariff pricing. It has its own powertrain and suspension but otherwise is almost identical in looks and features to the dual-motor trims.
Standard features include 20-inch alloy wheels, panoramic glass roof, acoustic laminated windshield and rear window, auto-extending flush door handles, power rear liftgate with foot sensor, power adjustable and heated, auto-dimming, and folding frameless side mirrors. Inside are standard heated and power adjustable front seats with extendable thigh bolsters, ambient interior lighting, tri-zone heat-pump climate control, rear touchscreen for climate and seat heating controls, and a 10-speaker audio system.
If your regular driving conditions don’t require all wheel drive and you don’t mind taking a couple of seconds longer to hit 60 from a standing stop, the single-motor version makes a lot of sense.
The dual-motor Polestar 3 starts at $74,800. It includes all the single-motor variant’s standard features and adds more power, electronic all-wheel drive with torque vectoring, and air suspension with active dampers. The dual motor AWD with Performance Pack jumps to $80,800 and includes everything on the standard dual motor but adds a performance software upgrade that boosts horsepower and torque. It also gets 22-inch alloys with performance tires, special chassis tuning, and gold-color seatbelts, valve caps, and brake calipers.
The Plus Pack, priced at $5,500, adds a head-up display, power adjustable steering column, soft-close door mechanism, heated rear seats and steering wheel, heated windshield wiper blades, and a foldable rear cargo bay floor. Also provided is a 25-speaker Bowers & Wilkins audio system with surround sound, Dolby Atmos capability, and active road noise cancellation.
Available only with the Plus Pack at an additional $5,500 is a combination of animal welfare certified Nappa leather upholstery in three color choices and dark ash wood trim. The Performance Pack, at $6,000 and available only for the dual-motor variant, adds 22-inch alloy and performance tires, a software upgrade that boosts horsepower and torque, sport and performance tuned chassis, and gold-colored seatbelts, brake calipers, and valve caps. A $2,100 Pro Pack option for the single-motor and base dual-motor variants adds specially designed 21-inch wheels, gold-colored valve caps, and black seatbelts with a gold center stripe.
All Polestar 3 variants use a 111-kilowatt-hour battery pack (107 kWh usable capacity) installed under the floor in a so-called skateboard EV platform. For the single-motor version, the battery supplies a rear-mounted motor rated at 299 horsepower and 361 lb.-ft. of torque. Dual-motor variants get an additional motor for the front axle. Combined, they produce a total of 489 horsepower and 620 lb-ft torque. The Performance Pack boosts that to 517 hp and 671 lb-ft.
Polstar says the standard dual-motor version can zoom from zero to 60 mpg in 4.9 seconds. Adding the Performance Pack cuts that to 4.6 seconds – at a cost of $2,000 per tenth of a second. The single motor Polestar 3 get to 60 in a more leisurely but perfectly acceptable 7.5 seconds, per Polestar’s estimate.
In any configuration there’s a decent amount of power, which is good because the Long-Range Dual Motor Polestar 3 weighs in at more than 2.5 tons in its lightest configuration, and is just 120 pounds short of 3 tons at its heftiest. The single motor version is some 200 pounds lighter than the base dual-motor Polestar 3.
The single motor version gets steel coil springs, passive dampers, and a rear motor without torque vectoring. Steering calibration is also a little softer in the single motor model. In our test drive we found it to deliver a comfortable ride and compliant handling, but its suspension couldn’t compensate for rough roads and high-speed corners quite as well as the dual moor variants’ more sophisticated system.
Dual motor Polestar 3s get adaptive air suspension and a rear-biased, electronic all-wheel drive system with torque vectoring that lets the Polestar 3 put its power to the road quite effectively and sure-footedly. All versions get four-piston Brembo front brakes with single-piston Brembos in the rears and they handle the vehicle’s weight with aplomb. A one-pedal drive setting for the Polestar 3’s multi-stage regenerative braking reduces brake-foot fatigue in crowded traffic and can mimic a downshift when turning or carving up a twisty country road.
We didn’t find either version of the Polestar 3 to be unwieldly or unbalanced when tossed around mountain corners or while carving winding roads, but our preference was for the double-motor variants’ air springs and adaptive dampers.
The single motor Polestar 3 with optional 21-inch wheels and all-season tires is EPA-rated at up to 350 miles of range, dropping to 342 miles with the standard 20-inch tires and 333 miles with 22-inchers. Dual-motor versions are rated at 315 miles with 21-inch wheels, 310 miles with the standard 20-inch wheels, and 287 miles with 22-inch wheels.
Adding the performance pack gets up to 300 miles of range. The Performance pack with its standard 22-inch alloys and sticky performance tires drops the estimated range to 279 miles. While the smaller 20-inch tires should deliver less rolling resistance and thus more range than the 21-inchers, the 20-inch wheels are made of cast aluminum, which makes them heavier and thus slightly less energy efficient than the forged aluminum wheels used with the 21 inch rubber.
At a DC fast charger, the Polestar can replenish its battery pack at up to 250 kilowatts per hour, good for a 10 to 80 percent recharge in 30 minutes. For home charging, the Polestar, like its competitors, uses an 11 kW Level 2 charging system. With properly sized 240-volt equipment, the Polestar can take a battery from 10 to 100 percent in 11 hours. Both DC and Level 2 charging speeds are competitive in the segment.
Polestar 3 has a Scandinavian minimalist interior that would have been avant-garde had it been rolled out a few years ago, before the Hyundai Motor Group set the standard for modern minimalism with its Hyundai and Kia small crossover interiors.
In the Polestar 3, the dashboard is divided into a padded textile-covered upper section with a textured plastic or optional aluminum or wood-trimmed lower face, divided by a thin strip of LED lighting. The dash houses a 9-inch-wide digital driver information screen and a centrally mounted, vertically oriented 14.5-inch infotainment touchscreen that also serves as a control center for almost all vehicle settings and functions. The only physical switches and knobs are vehicle function and driver display control buttons – unlabeled - on the steering wheel, the shifter, and turn signal stalks on the steering column. A rotary controller for the audio system is located on the center console’s floating bridge.
Power-adjustable, sports-styled front bucket seats are set low to maximize headroom and are both supportive and comfortable. The 60/40 split rear seat sits higher than the front seats for improved lines of sight for rear occupants. The bench is divided into three molded seating positions, and while the middle position is narrow, there’s decent rear legroom even for center-seat occupants since below-floor batteries allow a flat floor with decent legroom.
The Polestar 3 has a small-for-the-segment primary cargo bay providing 17.1 cubic feet behinds the rear seats, which we’re told allows carrying along about 15 grocery bags or five airline carry-ons. In contrast, the BMW iX features more than twice the Polestar’s capacity at 35.5 cubic feet with the Mercedes-Benz EQE SUV offering 20 cubic feet. Things improve when the Polestar 3’s rear seat back is folded down as this boosts total interior cargo capacity to 49.8 cubic feet. That’s still the least of the competitive set, though, with the iX boasting 77.9 cubes of maximum interior cargo space that takes the lead.
There’s also a 1.1 cu.-ft. storage area, or “frunk,” under the hood. It’s not large enough to be of much use but will hold a portable charging cord that otherwise would take up open cargo space in the rear. Among likely competitors, the Audi Q8 e-tron has a 2.1-cu.-ft. frunk while the BMW iX and Mercedes EQE SUV do without.
Polestar says the “3” can haul up to 220 pounds on its roof and dual-motor versions can tow up to 3,500 pounds. That tow rating is adequate for a small utility trailer but comes in less than the 5,500 pound rating of the BMW iX or the 4,000 pound rating of the Audi Q8. The Mercedes isn’t tow-rated in the U.S. The single-moor Polestar 3 is rated to tow up to 2,000 pounds.
Polestar uses an Android Automotive operating system for its infotainment centers. We’ve found it to be one of the most user-friendly interfaces around, especially for those who prefer to use voice commands, which are executed in everyday language after a “Hey Google” wakeup call. The built-in Google Play Store makes downloading new apps to the system easy. There’s 5G connectivity available, along with Google Maps with a 3-year constant internet connectivity plan at no charge.
Connectivity is enhanced with four USB-C ports – two for each seating row – and a 120-volt outlet in the rear cargo bay. Wireless phone and Bluetooth phone connectivity are standard as are Android Auto and Apple CarPlay compatibility. If there’s a drawback to the infotainment setup it’s that it is also control central for almost all vehicle adjustments and functions. This requires drivers who like to adjust drive modes, cabin temperature, and the like while underway to shift their eyes from road to screen far too often.
Audio is handled with a 10-speaker system. A 25-speaker Bowers & Wilkins sound system with Dolby Atmos surround sound and headrest speakers is an option. Three external speakers broadcast a warning tone at low speeds so that pedestrians, cyclists, and others can hear the otherwise silent EV as its draws near.
As a new model on a new platform, the Polestar 3 hasn’t yet been crash-tested by the National Highway Traffic Safety Administration (NHTSA) or the nonprofit Insurance Institute for Highway Safety (IIHS). It has received a 5-star safety rating in the European NCAP crash test program.
Polestar 3 is equipped with an impressive array of advanced safety and driver assistance technologies, all integrated via a centralized computer running on software developed by Volvo Cars. The driver assistance and safety systems use a variety of imaging systems to monitor external surroundings and conditions, monitor driver alertness, and even report in-car movement to help prevent accidentally leaving pets or children in a parked car.
Standard safety and driver assist features on the 2025 Polestar 3 include front collision avoidance and mitigation with braking and steering assist, pedestrian and cyclist detection, blind spot and rear cross traffic alert, rear collision mitigation, and driver alertness monitoring. Adaptive cruise control featuring full stop-and-go functionality along with lane keeping and centering with lane departure warning are also standard fare.
The Polestar 3 stands out for its unfussy good looks, user-friendly operating interface, and sporty ride, though its cargo bay isn’t as useful as some because of the rearward sloping roofline.
We certainly hope Polestar’s challenges don’t prove fatal. It has lost money every year since it was spun off from Volvo, had to delay production of the 3 for almost a year because of software issues, and hasn’t yet managed to achieve widespread name recognition in the U.S. Still, its vehicles are world-class EVs and the Polestar 3 belongs on any premium performance SUV shopper’s must-test list.
While performance is a given at any level, it’s been Tesla’s highest-end, dual-motor models that really set the bar for the ultimate in electric drive thrill seekers. While Tesla has pretty much had a lock on this for some time, serious competition has been in the pipeline. Audi’s new-for-2022 e-tron GT not only considerably extends the reach of Audi’s unfolding all-electric e-tron lineup, it presents a compelling option to those who would otherwise consider a Tesla.
Sleek and sinewy, the e-tron GT is what electric performance should be about. If Audi’s 610 horsepower, V-10 powered R8 supercar screams performance, then the more luxury-oriented electric e-tron GT simply exudes it in a refined and luxurious sort of way, without making a fuss. The e-tron GT is beautifully designed with a sloping roofline, a long wheelbase, wide stance, and large 20-inch alloy wheels as standard fare, with the uplevel RS variant offering available 21-inch alloys.
And performance? As expected. Front and rear permanently excited synchronous motors in the GT – 235 horsepower at the front and 429 at the rear – offer a net combined output of 469 horsepower for exhilarating acceleration. A greater 522 horsepower with overboost and launch control is delivered for a brief 2 1/2 seconds as needed. This delivers a 3.9 second 0-60 mph sprint and a top speed of 152 mph. The RS e-tron GT uses the same front motor but integrates a more powerful 450 horsepower motor at the rear, offering 590 horsepower overall and 637 horsepower with overboost. It reaches 0-60 mph in just 3.1 seconds, matching the breathtaking performance of Audi’s V-10 R8.
Power in both versions is delivered to the road via a two-speed transmission that accentuates quick acceleration while providing a second taller gear for extended highway driving. All-wheel steering, available in GT models and standard in the RS e-tron, provides a maximum of 2.8 degrees of opposite direction in the rear to increase low-speed agility at speeds up to 30 mph, and in the same direction at higher speeds to aid stability. Three-chamber air suspension is standard to enable tuning for comfort or performance.
Energy is delivered to the motors by a 93.4 kWh lithium-ion battery pack housed within an aluminum frame. Audi estimates a 238 mile range for the GT and 232 miles for the RS GT based on its own testing approximating EPA test cycles. Both are standard and fast charge capable, with the latter bringing the e-tron’s battery from 5 to 80-percent charge is just over 22 minutes.
Arriving this year, the Audi e-tron GT quattro Premium Plus carries an MSRP of $99,900, with the GT quattro Prestige upping the ante to $107,100 and the RS e-tron GT to $139,900.
When Audi introduced its all-new A3 generation in the U.S. in 2014, only the sedan was offered with the promise that the popular Sportback version would be coming. That follow-up is the A3 e-tron, the exclusive A3 Sportback choice here in the 2016 model year. This exclusivity makes this $37,900 A3 e-tron all the more special.
The A3 e-tron plug-in hybrid makes use of the same 150-horsepower, 1.4 liter TFSI gasoline engine and six-speed S tronic transmission as conventional Sportbacks available in offshore markets. The e-tron adds a liquid-cooled, 102 horsepower electric motor to deliver a satisfying 7.6 second 0 to 60 mph launch and the kind of spirited driving experience expected of an Audi.
The car’s lithium-ion battery pack is located beneath the rear bench seat, allowing fold-flat seats and the hatchback utility of a Sportback since there’s no battery intrusion in the cargo area. This battery allows up to 17 miles of all-electric driving to handle typical around-town driving chores.
Driving on battery and hybrid power delivers an overall driving range of just under 400 miles. Fuel economy is an EPA estimated combined 89 MPGe when running on battery power and 35 mpg in hybrid mode.
Audi likens its A3 Sportback as kind of a Swiss Army Knife of hybrids because of its four selectable driving modes. EV mode provides pure electric driving, the default mode at every start. Hybrid mode chooses the most efficient power and is ideal for long distances. Hold Battery mode preserves charge and saves EV power for later use. Charge Battery mode charges the battery during highway driving to ensure plenty of electric range when returning to an urban area.
With the A3 Sportback e-tron, Audi set out to prove that efficiency and performance can co-exist in a premium vehicle, without sacrifice. By all measures it has accomplished this goal.
Coinciding with the release of symposium co-sponsor Alcantara’s fifth annual Sustainability Report, the International Symposium on Sustainability brought together leaders in the automotive field including manufacturers, NGOs, and academics from leading universities.
Staged at the prestigious Venice International University in Venice, Italy, the symposium’s purpose was to share ideas and, at times, argue salient points from varying perspectives to redefine sustainability as it impacts global welfare. Green Car Journal was in attendance to hear first-hand the divergent perspectives.
Presenters and panelists included top industry executives from Alcantara S.p.A, Audi AG, BASF Group, Formulec Co., General Motors, and PSA Peugeot Citroen. On the academic side there were directors and leaders from Aarhus University, Ca' Foscari University's Center for Automotive and Mobility Innovation, Ecole Politechnique de Paris, Kedge Business School, University of Lausanne, and Venice International University. The World Bank and Connect4Climate were also represented.
As a buzzword, the term ‘sustainability’ has been overused and is rarely consistently defined in standard conversation. For some it is simply a financial term used for keeping profitability high enough for production to move along at a healthy pace. For others, it is keeping product lines fresh and appealing to draw sufficient consumer interest and maintain long-term existence. Regardless of perspective or intent, today sustainability has become an initiative of strategic importance in conducting business around the world.
Throughout the course of the two-day symposium, discussion netted some solid resolutions for change in addition to opening a dialogue for future consideration. It was perhaps the conflicting perspectives that generated the most interesting results and demonstrated some of the voids between academic perspectives and practical applications by major manufacturers. This is not unique to a single symposium and, in fact, the disparity in viewpoints between automakers and academia was previously noted by Green Car Journal at its Green Car Summits on Capitol Hill in the States.
The International Symposium on Sustainability was conceived to explore three fundamental topics for better understanding the challenges that the automotive industry will face in years to come, focusing on consumer perceptions, sustainability indicators, and products technology. In addition, its goal was to explore the possible trajectories and development paths the industry could take to achieve its sustainability goals.
A belief that current products and technologies are not sustainable was a common thread in symposium discussions, even as there was recognition that much has been done in recent decades to curb the auto industry’s negative impacts. It was also recognized that not only products but also the processes implemented to produce them need to be greener, with an inclusive focus on the entire value chain and not exclusively on automakers.
No one was more outspoken about corporate infractions to the environment and supply chain worker conditions in poor countries than Professor Guido Palazzo, Director of the Strategy, Globalization, and Society Department at the University of Lausanne. Kicking the symposium into high gear right from the start, Palazzo called for major change by what he referred to as ‘global business actors.’
“We have unclear or non-existent rules of the global game, which generates a growing negative impact on multinational business activities,” said Palazzo. “There are direct political struggles between corporations and the civil society, which will ultimately create changes leading to corporate engagement in filling global regulatory gaps and self-regulation. This is a compound agenda that will not change overnight.”
Professor Palazzo shared the perspective that a ‘radical transparency’ change is long overdue with regard to production processes and the inclusion of workers and unions in formulating policies that achieve environmentally friendly production. Manufacturers do not believe that such radical change is possible if profitability – and their very own corporate sustainability – were to be maintained, said Palazzo. While there is no conflict with regard to the need to achieve carbon neutrality, he pointed to the corporate orientation as one of taking smaller steps to work towards the common good. Investing time to research supply chain policies to ensure that products are created in more environmentally responsible ways is a given as part of this.
In his presentation, Frank Figge, Professor of Sustainable Development and CSR at Kedge Business School, noted that the world is 90 percent dependent on petroleum today and this handcuffs the market to an “environmentally damaging source of power.” Indeed, there was a clear consensus among those attending that dependence on oil was the most significant hurdle.
Also supporting this was GM Director of Sustainability David Tulauskas, who said that moving away from petroleum and toward alternative sources of power is needed for vehicles, with safe and cost-effective transportation systems created to support sustainable lifestyles. He added that consumers are at the center of what automakers do and they increasingly want advanced vehicles that address this.
Thorsten Pinkepank, BASF Group Director of Corporate Sustainability Relations, shared that companies not only need to do good but need to know how to do good, pointing out that driving sustainable solutions to current challenges is both a major growth initiative and a responsibility for all.
Consumer behavior is co-determined by motivation, ability, and opportunity, said John Thøgersen of Aarhus University. He added that the gap between motivation and behavior is rooted in many causes with no magic bullets to solve this problem, and in fact a wide range of techniques are needed to facilitate willing participation and make ‘sustainable choice’ the easy choice for consumers. According to Thogersen, energy labels like those indicating fuel economy and CO2 emissions on new cars can be effective tools for change, but improvements in the clarity of labeling and education of consumers is still warranted.
Alcantara Business Development Leader Eugenio Lolli shared that his company was pushed on creating quality product by its Japanese competition. But he also noted it was the edict laid down by management to achieve 100 percent sustainability that allowed Alcantara to reach its goals, with this sustainability not only achieved through the production of materials but also with suppliers through self-assessment and audits.
“We need to improve the quality of our lives and modify the way we use our cars,” stated Andrea Boragno, CEO and Chairman of Alcantara as he summarized how the nature of the car is changing. His conclusion was that we need to push for a better understanding and sharing of sustainability technology to achieve the goals and standards being set for manufacturing and consumer goods.
Simply stated, current products and technologies are not sustainable, although much has been done in recent decades to curb the negative impacts of the industry. Importantly, not only products but also the processes implemented to produce them need to be greener, with specific focus on the entire value chain and not only on carmakers.
According to Professor Palazzo, the challenge can be summarized by the following: The way we produce products in the world is not sustainable at the current rate. Even if a company ‘greens up’ its supply chain, that may not be enough to have an impact on a company’s sustainability. There is current concern for the ability to market ‘green’ initiatives on their own. Importantly, there is a need to understand that change is required by those running corporations today. He also added that consumers have routines that are deeply entrenched, thus there is a duty to educate the consumer and transform their mindset for sustainable product creation and a preference for companies that have sustainable production.
Concluded Professor Palazzo: “We cannot continue at our current mode for two billion cars. It is unrealistic. We need a different system…the current one makes us sick. We need to change the way we live today.”
Illuminating the road ahead is a crucial element in driving. It’s also one that has long benefitted from technological innovation. To this end, Audi celebrates the evolution of automotive lighting with its Sport quattro laserlight concept car. The high performance, two-door, Plasma Red coupe harkens back to the iconic 1983 Sport quattro even as it’s abundant advanced technology and design cues point to the future.
The laserlight concept is named for its future lighting technologies. Two low-profile trapezoidal elements are visible within the headlights. An outer one generates low beam light using matrix LEDs and an aperture mask, while an inner element produces laser light for the high-beam.
Laser diodes are significantly smaller than LED diodes, only a few microns in diameter. They can illuminate the road for a distance of nearly 1,640 feet, approximately twice the lighting range with three times the luminosity of LED high beam lights. This technology is finding use in the 2014 R18 e-tron quattro for track duty.
Motivating the laserlight concept is a 4.0-liter, bi-turbo V-8 TSFI (turbo stratified fuel injection) engine and a disc-shaped electric motor located between the engine and transmission. The V-8 produces 560 horsepower and 516 pound-feet torque, with the electric motor contributing an additional 148 horsepower and 295 pound-feet torque. A modified eight-speed Tiptronic transmission is mated to the quattro drivetrain with a sport differential at the rear axle.
Electrical energy is stored in a 14.1 kilowatt-hour lithium-ion battery, sufficient for 31 miles of all-electric driving. When the V-8 and electric motor are working together, the Audi Sport quattro laserlight concept can accelerates from 0 to 62 mph in 3.7 seconds. Top speed is 189 mph. This impressive performance comes with an equally impressive 94 US mpg fuel economy. This is achieved in part through its electric plug-in operation in addition to a cylinder on demand system that deactivates four cylinders of the V-8 under partial load. Also helping is a start-stop system and several levels of regen braking to enhance driving dynamics.
Drivers can switch between three different modes. In EV mode, just the electric motor operates with sufficient high torque power, even outside the city. The active accelerator pedal indicates the transition by a change in pedal resistance so a driver can intentionally influence the mode selection. The Hybrid mode provides optimal interplay between the V-8 and the electric motor for best fuel-savings, and additionally incorporates environmental and route data. A driver can choose the Hold and Charge modes to ensure sufficient electrical energy is available for electric-only driving at their destination. There are different levels of regenerative braking to enhance the driving experience.
The laserlight’s multifunction sport steering wheel has buttons to control the hybrid drive, start-stop function, vehicle handling system, and the car’s virtual cockpit. Key information is shown on the large Audi TFT display in high-resolution 3D graphics. A cutting-edge Nvidia Tegra 30 processor handles the graphics.
Nearly all functions can be controlled from the further-developed MMI mounted on the center console. Its large rotary pushbutton, which also serves as a touchpad, can be pushed in four directions. It’s surrounded on three sides by four buttons that control the main menu, submenus, options, and a back function. The intuitive layout is similar to a smart phone with all frequently used functions accessed lightning fast.
Lightweight design plays a major role in the Audi laserlight concept’s dynamic performance. A combination of ultra high-strength steel sheet and structural elements of cast aluminum is used in the occupant cell. The doors and fenders are made of aluminum, with the roof, engine hood, and rear hatch and other components made of carbon fiber reinforced plastic (CFRP). Thus, the concept weighs 4,079 pounds including the weight of the large battery pack.
It’s hard not to wear a broad grin while driving Audi’s 2014 A6 TDI. One of a growing array of upscale TDI models in the Audi stable, the $57,500 A6 TDI presents a compelling case for premium mid-size sedan buyers to go clean diesel. Time behind the wheel illustrates the well-balanced nature of the A6 TDI, which artfully blends luxury, comfort, performance, and efficiency in a very desirable package. Plus, it’s just fun to drive.
The A6 TDI’s 3.0-liter turbocharged direct injection V-6 is surprisingly quiet and smooth, dispensing with the two inherent challenges that diesel as a whole has faced in attracting U.S. buyers in the past. Ride quality, handling, and overall driving characteristics are excellent. The A6 TDI is powerful, with strong low-end torque pressing you back in the seat with ease while delivering 240 hp and an impressive 428 lb-ft torque. All this power is channeled to the highway via an 8-speed tiptronic transmission and quattro all-wheel drive. Acceleration from 0-60 mph is achieved in a quick 5.5 seconds.
This level of power-at-the-ready does not sacrifice efficiency as one might expect, particularly in highway driving as the model achieves a rather impressive 38 mpg. Total driving range of over 700 miles is possible. The TDI clean diesel’s inherent efficiency is bolstered with other efficiency measures including a relatively lightweight chassis and aluminum body panels, plus a start-stop efficiency system that shuts the engine down under specific conditions such as extended idling or at stoplights. The engine restarts instantly when a driver releases the brake pedal.
Driving performance and efficiency are just part of the story with the Audi A6. This model makes a point of enveloping driver and passengers in a luxurious and accommodating interior, paying great attention to detail throughout the cabin with a curved wraparound dash, fine leather, and high-end materials. Instrumentation and controls are well placed and intuitive.
Infotainment and connectivity features are extensive with MMI Navigation plus and Audi connect, which offers Google Earth mapping and in-vehicle Wi-Fi connectivity for up to eight wireless devices. Available are an array of sophisticated features including night vision assistant, heads-up display, and Audi pre sense plus, the latter system helping to detect imminent collisions and initiate protective measures.
The A6 TDI presents a very upscale exterior with sharp lines and unmistakable Audi design cues, among these Audi’s signature LED lighting technology. Add in efficient and responsive TDI power and the package gets even more compelling.
We are all enamored by the advanced technologies at work in vehicles today. And why wouldn’t we be? The incredibly efficient cars we have today, and the even more efficient models coming in the years ahead, are testament to a process that combines ingenuity, market competitiveness, and government mandate in bringing ever more efficient vehicles to our highways.
It’s been a long and evolutionary process. I remember clearly when PZEV (Partial Zero Emission Vehicle) technology was first introduced in the early 1990s, a breakthrough that brought near-zero tailpipe emissions from gasoline internal combustion engine vehicles. That move was led by Honda and Nissan, with others quickly following. Then there were the first hybrids – Honda’s Insight and Toyota’s Prius – that arrived on our shores at the end of that decade. Both technologies brought incredible operating efficiencies that drastically reduced a vehicle’s emissions, increased fuel economy to unexpected levels, or both.
Of course, there were first-generation battery electric vehicles in the mid-1990s that foretold what would become possible years later. That first foray into EV marketing was deemed by many a failure, yet it set the stage for the advanced and truly impressive EVs we have today. Those vehicles may not yet be cost-competitive with conventionally powered vehicles due to very high battery costs, but that doesn’t diminish the genius engineering that’s brought them to today’s highways.
Even conventionally-powered cars today are achieving fuel efficiency levels approaching that of more technologically complex hybrids. Who would have imagined popular cars getting 40 mpg or better, like the Dodge Dart, Chevy Cruze, Mazda3, Ford Fiesta, and many more in a field that’s growing ever larger each year?
VW and Audi have proven that clean diesel technology can also achieve 40+ mpg fuel efficiency while providing press-you-back-in-your-seat performance, and importantly, doing this while meeting 50 state emissions criteria. That’s saying something considering diesel has historically had a tough go of it meeting increasingly stringent emissions standards in California and elsewhere. Yet, with elegant engineering by these automakers and their diesel technology supplier Bosch – plus this country’s move to low-sulfur diesel fuel late last decade – ‘clean’ diesel was born.
I would be remiss if I didn’t mention natural gas vehicles. There was a time when quite a few automakers were exploring natural gas power in the U.S., but that faded and left Honda as the lone player in this market with its Civic Natural Gas sedan. Now others are joining in with dual-fuel natural gas pickups and vans, benefitting from advanced engine technologies, better natural gas tanks, and a sense that with increasing natural gas reserves in the U.S., demand for natural gas vehicles will grow. As Honda has shown with its Civic, it’s possible to operate on this alternative fuel while also netting admirable fuel efficiency.
All this advanced powertrain technology is important. It makes air quality and petroleum reduction goals achievable, even ones like the ethereal 54.5 mpg fleet fuel economy average requirement that looms for automakers by 2025. There’s no doubt that advanced technologies come at a cost and reaching a 54.5 mpg average will require the full range of efficiency technologies available, from better powerplants and transmissions to greater use of lightweight materials, aerodynamic design, and answers not yet apparent. But I’m betting we’ll get there in the most efficient way possible.

Audi is fielding four LMP1 cars at the upcoming 24 Hours of Le Mans this coming June. Importantly, two of these will feature hybrid powerplants for the first time.
The pair of Audi R18 e-tron quattros recover kinetic energy during braking and feed this back as electricity to a flywheel accumulator, which powers an electric motor at the front wheels to aid acceleration at speeds above 75 mph. The car’s 510 hp V-6 TDI powerplant drives the rear wheels.
Audi Motorsport head Dr. Wolfgang Ullrich points out that developing its hybrid technology for Le Mans is at least as ambitious and challenging as its diesel racing project was in its early stages. That said, results have been very encouraging and the motorsports team is eager to see how the R18 e-tron quattro’s hybrid systems perform in concert with their ultra-lightweight technology.
Innovating its way to wins is nothing new to Audi, which achieved the first win for a TFSI (Turbocharged Fuel Stratified Injection) engine in 2001 and for a TDI (Turbocharged Direct Injection) diesel-powered car in 2006. The automaker is the most successful brand in the race’s recent history with 10 wins at the 24 Hours of Le Mans since 2000.
