Stellantis aims to eliminate separate inverter, charger to improve EV efficiency

Stellantis has announced that, in collaboration with French battery company Saft and French National Center for Scientific Research, has made significant progress in eliminating two major components of an electric vehicle powertrain: the on-board charger and the power inverter for the motor. The company claims that doing this will allow for better space use in vehicles, as well as improvements in efficiency, cost and reliability of components. As a quick primer, also explained in the below video, the on-board charger and power inverter are sort of translators to get the right current to different parts of the electric powertrain. The on-board charger takes AC power from the grid and converts it to DC to charge the batteries. Then when power goes from the batteries to the electric motor, the power inverter converts that DC power back to AC. These components aren't exactly small. Frequently you'll find them packaged somewhere under the hood. What Stellantis and its cohorts have developed, and have been using on a test vehicle since last summer, are small power inverter boards that can be mounted very closely to the battery packs. They can handle both conversion needs, for charging and discharging, instead of needing two separate devices. The most obvious perk to this is that you can do away with those traditional components and free up more space, either for making smaller vehicles without losing interior volume, or adding space to a vehicle that wouldn't have had it otherwise. There's the additional benefit of reduced weight, something that EVs struggle with. Stellantis also claims improvements in efficiency, reliability, and cost, however, it didn't go into detail as to how this setup would do that exactly. We'll try to get in touch with representatives from Stellantis in order to get more information. We're still a ways out from seeing this technology in production Stellantis vehicles. The company said it aims to apply it to vehicles by the end of the decade. Saft is also looking at using it on stationary battery systems as well. So maybe we'll see it on a 2029 Ram 1500 REV, but for now, we'll be living with traditional chargers and inverters. Related Video: Green Alfa Romeo Chrysler Dodge Fiat RAM Technology Electric

Tesla leads and Infiniti bleeds in Consumer Reports' satisfaction survey

According to Consumer Reports, Tesla owners are more likely to rave about their vehicles than any other brand. And we're not surprised — Tesla has performed very well in past customer satisfaction surveys, despite the fact that the electric cars themselves tend to have more problems than most other automobiles. Second place went to Lincoln, which interestingly had a higher cumulative score than Tesla in individual category measurements like comfort and storage space. Ram, a truck-only brand, rounded out the top three. The consumer-focused magazine bases its owner satisfaction score on responses to a very simple question: Would you buy this exact car again? The higher percentage of owners who answer "definitely yes" to that question, the higher the satisfaction score. Further breakdowns are scored for other parts of the ownership experience, which is why brands that rank poorly in Consumer Reports' own reliability charts — like Tesla and Lincoln, for example — can still earn top marks for satisfaction. The lowest-ranked brands for satisfaction are Cadillac, Nissan and Infiniti. Interestingly, Cadillac performed better than average in Driving and Comfort and middle-of-the-road in the In-Car Electronics and Cabin Storage, but like most other brands, scored poorly in Value. In fact, only Subaru, Mazda and Volkswagen scored better than average in Value. Nissan and especially Infiniti earned comparatively low marks across the board to go along with the bottom-of-the-barrel satisfaction score. Here's the full list of automakers from Consumer Reports' satisfaction survey, ranked in order from best to worst: Tesla Lincoln Ram Chrysler Subaru Hyundai Porsche Dodge Mazda Toyota Kia Mini BMW Ford Audi Honda Volvo Volkswagen Lexus Jeep GMC Chevrolet Mercedes-Benz Buick Cadillac Nissan Infiniti It's worth diving into the individual category scores in addition to the official finishing order for a full look at the results. For instance, despite the fact that automakers like Lincoln and Ford use similar infotainment systems, their In-Car Electronics scores don't quite match up. Also, some automakers have full lineups with multiple cars, trucks and SUVs while others offer just a couple of nameplates. Head on over to Consumer Reports for all the details.

2017 Ram 2500 Power Wagon demos off-road abilities in Chicago

In today's world, big budget auto show debuts involve lots of music and video, with a car docilely rolling onto the stage. Practical demonstrations of abilities are few and far between. Ram didn't get that memo, though, and decided to give attendees at the 2016 Chicago Auto Show a taste of just what the new Power Wagon can do off road, showing some extreme suspension articulation before crawling the big pickup down a flight of stairs. It was an impressive display for the facelifted pickup, which retains all the things that made the Power Wagon such a monster while improving on its overall aesthetic. The two-tone styling looks great in person, and even the controversial grille – which many of our readers cited as being a problem in our debut post – looks nicer in the flesh than in static shots. The upholstery, too, with its tire-tread imprints looks better in real life, and we're digging the Power Wagon and Ram logos sprinkled around the high-riding thrones. You can read a deeper dive into the new new truck in our introduction post from early this morning. We've also got a smattering of images of the new Power Wagon on the show floor and a video of the flashy debut in Chicago. Have a look.
