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.

We check out Hyundai's HRL exoskeleton, a robotic mobility suit for paraplegics

Hyundai makes some of the largest vehicles in the world – to wit, 185,000-ton ships with 56-foot high engines making power at 84 rpm – but its R&D division has found enough human-factor synergy with autonomous vehicle development that they're now working on robotic exoskeletons. We were recently introduced to two of these devices: the HRL designed to increase mobility and therefore quality of life for paraplegics; and the WEX, designed to assist in repetitive-motion lifting. Both of these machines are powered by replaceable lithium-ion battery packs with a 4-hour run time and 40-minute recharges. The HRL robotic legs are designed for people 64 to 71 inches tall and less than 250 pounds. The aluminum segments are adjustable in centimeter increments over a 10-cm range, and the 22.4-inch width means it would fit in many long-haul aircraft forward seats. With the 4.4-lb battery pack, the HRL weighs about 41 pounds. There are six 50:1 reduction-gear actuators, two pelvic actuators rated at 224 pound-feet of peak torque with 60-degree range of motion, and two hip and knee with 112 lb-ft peak, 180 degrees and twice the rotational speed of the pelvic motors. Twenty sensors control it all with default speed of just under a mile per hour and a top speed of 1.5 mph, and step length can be adjusted by smartphone via Bluetooth. One of the accompanying crutches has four thumb buttons much like a video-game controller, though they're experimenting with simpler inputs including a joystick. The crutch communicates with the leg unit over a few feet of distance via Zigbee wireless protocol, with security layers added for both obvious reasons and to ensure two users in the same vicinity won't transmit to the other's unit. An HRL can help you sit, stand, walk or climb and descend stairs; it will also stand on its own, simplifying the process of putting it on. Your correspondent is outside the design height limits so rather than do any impromptu CG research we deferred to colleague Chris Davies of Slashgear for impressions wearing it: "It grips tightly, the support would be comforting, and it delivers good posture. It does take some getting used to – when it first lifts up a leg to move it forward you do feel like you're going to fall over – but once you establish a gait and stop over-thinking it becomes much easier." Indeed, he never fell over and most who tried established a rhythm within a few minutes, if not a 1.5-mph sprint.

2017 Hyundai Santa Fe and Sport reveal facelifts in Chicago

Hyundai needs crossovers. With the national average cost of gas at just $1.71 as of this writing, (short-sighted) consumers are charging back to dealers demanding new high riders. That's bad news for car-heavy manufacturers like Hyundai, and good news for brands that have embraced CUVs, like Subaru. Consider this: Hyundai sold 181,725 crossovers from its roughly 800 dealers in 2015. In that same period, the Subaru Forester alone racked up 175,192 sales, and that's with a dealership network 25 percent smaller than Hyundai's. At the 2016 Chicago Auto Show, Hyundai is showing off updated versions of its two-tier Santa Fe range. There's a new, more pronounced and rectangular grille; sharper, less organic headlights, and LED running lamps in front. But there are also a bunch of new gizmos and gadgets that Hyundai expects to elevate the Santa Fe's safety rating. A backup camera is now standard and you can now snag adaptive cruise control with a stop-start mode. There's also a raft of new safety features, including lane departure warning, automatic high beam assist, and auto emergency braking with pedestrian detection. It's partially because of that last item that Hyundai thinks the new Santa Fe will score an IIHS Top Safety Pick+ rating. The company hasn't explained what changes will allow it to improve on 2016's Moderate rating in the small-overlap test, though. But if Hyundai is correct, it'd be a serious coup – the Santa Fe hasn't been honored by the IIHS since its redesign for model year 2013. It'd also put the Santa Fe in a rarefied class of ultra-safe mid-size CUVs. Only the Honda Pilot and Nissan Murano have scored TSP+ ratings. Prices increase by $400 on naturally aspirated models and $450 for the top-of-the-line turbocharged trims. The new Santa Fe is arriving at dealers now.
