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.

Almost Jeffersonian | 2017 Kia Optima Plug-In Hybrid Second Drive

On a drive of Kia's new Optima Plug-In Hybrid (in showrooms since April), we visited Thomas Jefferson's Monticello, our third president's sprawling estate in central Virginia. Even in the absence of Twitter, Jefferson enjoyed a restless curiosity about an array of subjects. While his day gigs – declaring independence and consummating the Louisiana Purchase – occupied much of his life, he always made time for intellectual pursuits and making daily life better, so we think he'd grasp the rightness of the Optima. In the science of the plug-in hybrid, there's little new. The combination of gas and electric motors is intended to reduce the carbon footprint of a conventional drivetrain. Add a motor, install more battery capacity and enable that battery to be recharged over a long lunch or overnight, and you have a plug-in hybrid with up to 29 miles of electric-only operation. With the gas tank included, you get roughly 600 miles of combined driving range. (That's DC to Atlanta, had Jefferson wanted to visit Atlanta.) Visually, there's little to distinguish this PHEV from a conventional Optima. Its alloy wheels are aerodynamically cleaner and front fascia less disruptive - and includes an active air flap, no less. The exterior design, though dated, still impresses. A spacious interior is what you'd expect from Kia. And so, regrettably, are some hard plastic surfaces. That plastic is appropriate in a $20,000 Soul, less so in a $40,000 Optima Plug-In. Nothing here is completely off-putting, and we've always liked Kia's integration of audio and A/C controls. But so much is good about the Optima that you expect something nicer as you slide behind the wheel. The front seats are both supportive and accessible. Our test vehicle, equipped with $5,250 of EX Technology, offered a panoramic sunroof, heated and ventilated front seats, a power front passenger seat with adjustable lumbar, and heated outboard rear seats. That same package also includes a bundle of safety technology, including a forward collision warning system, advanced smart cruise control, blind spot detection, lane departure warning, and rear cross traffic alert. A modern hybrid generates a lot of info, and learning to access it all will require more than the few hours we had in the car. Your economy – the Optima's innate efficiency and your driving style – is available at the push (or two) of a button. And you can choose from all-electric EV or hybrid mode by using Kia's Mode Select control.
