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.

Recharge Wrap-up: Mercedes stationary batteries, 2015 E-Mazing Race

Mercedes-Benz is following Tesla's Powerwall in selling stationary batteries for home, business, and industrial solar energy storage. The lithium-ion batteries will come in 2.5- and 5.9-kWh capacities, and can be linked together. Daimler's vehicle battery technology, "has proven to work for millions of driven kilometers in the toughest environments of heat and cold, which makes it the best candidate also for stationary use," says Harald Kroeger of Mercedes-Benz. Pricing is unavailable as of yet, but Mercedes promises "competitive" pricing when the batteries go on sale at the Intersolar trade fair (June 10 through 12) in Munich, Germany.

The race challenges drivers to earn the most points by charging at Sun Country Highway charging stations in a month. Contestants needn't have been at the official starting point nor cross the finish line; they just needed to sign up and download the race app to participate. More remote charging stations offer more points when charging, and participants can also win prizes for photos and using social media. The 2015 E-Mazing Race, which began May 27 and ends June 24, is meant to raise awareness of electric vehicles. Sun Country is working on expanding its EV charging infrastructure in the US, so don't be surprised to see the race encompassing most of North America in the future. Read more at Green Car Reports. Linde has opened a new hydrogen fueling station in Innsbruck, Austria. The station, located in the popular destination city that has twice hosted the Winter Olympics, will allow hydrogen-powered vehicles to cross the Alps and travel between Italy and Germany. The station is capable of 700-bar refueling and can fuel six cars per hour. It was built as part of the HyFive project to create hydrogen fueling infrastructure across Europe to facilitate the rollout of fuel cell vehicles. It is the second public hydrogen station in Austria. Read more at Green Car Congress, or in the press release below from Linde.

Mercedes gets handy with Apple Watch app

Whether you yourself have been caught up in Apple Watch fever or not, automakers have been embracing the new wearable device one after the other. The latest is Mercedes-Benz. The MB Companion App for the Apple Watch initially focuses on seamless navigation. Punch in your destination on your watch or iPhone and it'll port over to the onboard navigation system in your Merc. Park the car, get out and the directions will switch back over to the Apple Watch to guide you from your parking spot to your destination on foot. It's similar to the app Mercedes had designed for Google Glass, only in this application it actually stands a chance of catching on. Designed by Benz's Silicon Valley R&D center, the Apple Watch app is being rolled out this fall in the new C-Class and S-Class equipped with the COMAND Online navigation system. It's earmarked to to spread to other models as well, with further updates to the app planned to allow it to display the vehicle's fuel level, range, odometer and maintenance code. Of course, Mercedes isn't the first automaker to release an app for the Apple Watch. It's not even the first German automaker to do so: BMW previewed its app for the device back in September, and Volkswagen got on board earlier this month. Mercedes-Benz to introduce new App: Guided all the way: Mercedes-Benz is one of the first to introduce Door-to-Door Navigation with Apple Watch May 15, 2015 Stuttgart/Sunnyvale. Mercedes-Benz creates an intelligent integration between Apple Watch and Mercedes-Benz vehicles with its new MB Companion App. The MB Companion App allows Mercedes-Benz costumers to search for directions on the Apple Watch or on iPhone initiating a complete door-to-door experience. A seamless integration unfolds: giving walking directions to the car on the Apple Watch, driving directions on the vehicle navigation system and again walking directions on the Apple Watch from the car to the final destination. The destination that the driver selects on Apple Watch is passed to Mercedes-Benz COMAND Online once the driver starts the vehicle. He then receives safe and non-distracting driving directions to his selected destination from Mercedes-Benz navigation. When the driver parks and leaves his car, Apple Watch gives him walking directions to the final destination making it the perfect guide for "Last Mile Navigation".
