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.

Stanford goes from Pikes Peak to Thunderhill with autonomous Audi TTS

In the years since Stanford University engineers successfully programmed an Audi TTS to autonomously ascend Pikes Peak, the technology behind driverless cars has progressed leaps and bounds. Back then the Audi needed 27 minutes to make it up the 12.42-mile course – about 10 minutes slower than a human driver. These days, further improvements allow the vehicle to lap a track faster than a human. The researchers recently took their autonomous TTS named Shelley to the undulating Thunderhill Raceway Park, and let it go on track without anyone inside. The Audi reportedly hit over 120 miles per hour, and according to The Telegraph, the circuit's CEO, who's also an amateur racing driver, took some laps as well and was 0.4 seconds slower than the computer. To make these massive technological advancements, the Stanford engineers have been studying how racers handle a car. They also hooked up drivers' brains to electrodes and found the mind wasn't doing as much cognitively as expected. It instead operated largely on muscle memory. "So by looking at race car drivers we are actually looking at the same mathematical problem that we use for safety on the highways. We've got the point of being fairly comparable to an expert driver in terms of our ability to drive around the track," Professor Chris Gerdes, director of Stanford's Revs Program, said to The Telegraph. With progress coming so rapidly, it seems possible for autonomous racecars to best even elite drivers at some point in the near future. Related Video:

Audi A3 E-Tron goes carbon neutral with German green electricity deal

Audi is proving that the fresh water flowing through the European Alps isn't just for bottling and drinking anymore. The German automaker struck a deal with Hamburg-based LichtBlick to offer buyers of the Audi A3 Sportback E-Tron a chance to get their electrical juice from all renewable-energy sources. That means all the power going into charging stations can come from hydroelectric power from Germany, Austria and Switzerland. The nuts and bolts part of it is that users pay the equivalent of about $12.30 a month plus 37 cents per kilowatt hour for the service. And LichtBlick is indeed legit, as it has been certified by TUV Nord for having at least one third of its power come from hydroelectric plants that are were built less than six years ago. Audi is looking to boost sales from a model it unveiled at last year's Geneva Motor Show. The car pairs a turbocharged 1.4-liter four-cylinder engine with an electric motor that combines for 250 horsepower. Most importantly, the A3 E-Tron gets a combined fuel economy rating of 157 miles per gallon. And while that figure comes from the more generous European driving cycle, it's impressive nevertheless. Check out Audi's press release below and read the Autoblog Quick Spin here. Audi and LichtBlick offer green electricity CO2-neutral mobility with Audi energy TUV-certified green electricity from the energy provider LichtBlick As an accompaniment to the market launch of the A3 e tron*, Audi is offering customers in Germany green electricity – Audi energy. The cooperating partner is the Hamburg energy provider LichtBlick SE. With Audi energy, the A3 e tron is totally emission-free when operated electrically. The power all comes from renewable energy sources and is generated exclusively at hydro-electric power stations in Germany, Austria and Switzerland. The Audi A3 e-tron can be recharged when parked at your home with Audi energy. At the same time, the entire household is supplied with eco-friendly electric power. Audi energy is currently available for a basic monthly fee of EUR 8.95 and 26.76 cents per kilowatt-hour. The origin and quality of the green electricity are certified by TUV Nord. The "OK power" seal of quality also confirms the expansion of power generation from renewable sources: at least one-third of the electricity comes from hydro-electric power plants less than six years old. Providers of this green electricity do not make use of federal subsidies pursuant to the German Renewable Energy Act (EEG).
