Here’s how 20 popular EVs fared in cold-weather testing in Norway

Electric vehicles are known to suffer diminished performance in cold weather, but some do a better job than others hanging onto their range capacity while cabin heaters and frigid outdoor temperatures sap power from their batteries. Recently, the Norwegian Automobile Federation put the 20 of the best-selling battery-electric vehicles in the country to the test, to see not only how winter weather affected their range but also their charging times. The major findings: On average, electric vehicles lost 18.5% of their official driving range as determined by the European WLTP cycle. Electric vehicles also charge more slowly in cold temperatures. And interestingly, the researchers learned that EVs don’t simply shut down when they lose power but instead deliver a series of warnings to the driver, with driving comfort and speed levels maintained until the very last few miles. Because itÂ’s Norway, the worldÂ’s top market for electric and plug-in hybrid vehicles by market share, the test included many EVs that arenÂ’t available here in the U.S. But there are many familiar faces, among them the Nissan Leaf, Tesla Models S, 3 and X, Hyundai Kona (known here as the Kona Electric) and Ioniq, and Audi E-Tron. In terms of range, the top-performing EV was the Hyundai Kona, which lost only 9% of its official range, which the WTLP rated at 449 kilometers, or 279 miles, compared to its EPA-rated range of 258 miles on a full charge. It delivered 405 km, just enough to nudge it ahead of the Tesla Model 3, which returned 404 km. Other top performers included the Audi E-Tron, in both its 50 Quattro (13% lower range) and higher-powered 55 Quattro (14% lower) guises; the Hyundai Ioniq (10% lower); and Volkswagen e-Golf (11% lower). At 610 km (379 miles) the Tesla Model S has the longest WLTP range of all models tested and went the furthest, but still lost 23% of its range, though it also encountered energy-sapping heavy snow at the end of its test, when many cars had dropped out. The Model 3 lost 28% of its range. The worst performer? That goes to the Opel Ampera-e, better known stateside as the Chevrolet Bolt. It traveled 297 km (about 184 miles) in the test, which was nearly 30% lower than its stated WLTP range. We should also note that Opel, now owned by Groupe PSA, is phasing the car out in Europe and that Chevy recently upgraded the Bolt here in the U.S.

Audi SQ7 TDI packs 48V electric compressor, 664 lb-ft

Take a look at the new Audi SQ7 TDI. It's the first time Audi has done an S performance version of its flagship sport-ute, and packs under the hood a 4.0-liter V8 turbo diesel engine mated to an eight-speed automatic and all-wheel drive. It produces a potent 435 horsepower, and an absolutely bonkers 664 pound-feet of torque. The Audi SQ7 TDI produces a massive 664 lb-ft of torque. Impressive as it is, though, that doesn't even tell the full story. That's enough to make us forget it wasn't there in Geneva. It's also more torque than just about anything the Volkswagen Group makes – short of the Bentley Mulsanne Speed and the new Bugatti Chiron. Not even the Lamborghini Aventador SV or Bentley Continental GT Speed can touch that torque figure. Nor can competition like the Porsche Cayenne S Diesel (with its 385 hp and 627 lb-ft) or the BMW X5 M50d (381 hp and 546 lb-ft). It may not surpass the old twelve-cylinder Q7 6.0 TDI (with its 493 hp and 738 lb-ft), but still trounces the VW Touareg V10 TDI (309 hp and 553 lb-ft) – which was strong enough to tow a jet airplane, while the new SQ7 is fast enough to out-drag one (as you can see from the video below). Impressive as it is, though, that headline-grabbing torque figure doesn't tell the full story. To get there, Audi employed two conventional, sequential turbochargers and a third compressor that – in an industry first that's been a long time coming – is powered electrically. The engineers in Ingolstadt installed a beefier 48-volt electric subsystem to power the electric compressor (among other systems) and its latest valvetrain tech for the first time in a diesel. The result, Audi says, is a lack of any perceptible turbo lag – and a 0-62 time quoted at 4.8 seconds, en route to the typical electronically limited top speed of 155 miles per hour. As if that weren't enough, Audi also equipped the SQ7 TDI with an optional suspension package that coordinates the activities of three systems. There's a differential, a four-wheel steering system, and a clever electromechanical roll stabilization system that employs an electric motor (made possible once again by that 48-volt system) and a three-stage planetary gearbox to keep it all level and improve ride quality over rough surfaces. The sum total is an impressive technological tour de force on Audi's part, but one that we may just have to admire from afar.

Meet the first of four Audi A4s coming to our long-term fleet

Yes, you read that right, this is the first of a quartet of A4s we'll be looking at over the course of the year. We're kicking things off with an Audi A4 Premium Plus sedan, and we'll be looking at other iterations of the A4 line later on: the A4 Prestige, Allroad, and S4. What we hope to do is provide you with a thorough examination of each variation, and hopefully give you some guidance on what's worthwhile and what isn't. But first, let's introduce you to the A4 Premium Plus. What we got The A4 Premium Plus is the middle child of the standard A4 line, fitting between the entry-level Premium and the top level Prestige. Stepping up to the Premium Plus adds 18-inch alloy wheels, LED headlights, an S Line body kit, Bang & Olufsen sound system, parking sensors, aluminum window trim, and heated power seats with memory. The model we received from Audi has a number of upgrades that bring it quite close to the Prestige trim level. Most notable is the Technology package, which adds the Audi Virtual Cockpit instrument panel, which replaces the physical gauges with a big LCD screen. It also comes with rear cross traffic alert. A First Edition package was added, too, which adds cooled sport seats, a three-spoke steering wheel, and unique wheels and aluminum interior trim. Our favorite part, is the sport package, which adds sportier suspension, a black headliner, and the aforementioned sport seats. What we skipped Really, we didn't skip much here – this particular A4 Premium Plus is pretty loaded. The only packages not included were the Cold Weather package, which includes heated rear seats and steering wheel, and wheel and tire options. The heated steering wheel isn't necessary since winter is almost over (at least we hope). The cost of these packages added up fast, too. Moving up to the Premium Plus trim over the standard Premium added $3,800. The Technology package was $3,250, the First Edition package was $1,100, and the Sport package tacked on $750. Along with the white paint at $575, our Audi has over $9,000 in options. That brought our tester up to $49,825 from a base MSRP of $40,350. We like everything that's been added. If we were to pick packages we could live without, though, we'd probably pick the Technology and the First Edition packages. As slick as the LCD instrument panel is, there's nothing wrong with physical needles and dials.
