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

2018 Dodge Challenger GT Drivers' Notes Review | The right car for the season

Associate Editor Joel Stocksdale: Dodge uses the Challenger GT trim to denote its V6 all-wheel-drive model, but it seems apt for reasons besides that. The Challenger, even with a V6, is an excellent, affordable American grand tourer. It's still extremely stylish, despite barely changing looks since Dodge introduced it for the 2008 model year. The solid gray on this one was particularly attractive. It also seemed appropriate considering the Challenger's battleship size. This thing is truly massive. That's beneficial in the sense that it has an enormous trunk (perfect for touring), but not so much for maneuvering. But thankfully, it's easy to spot the corners, which helps a lot. The Challenger GT is a pretty able handler, too. It feels composed in corners, not too heavy, only mild body roll, and steering that weights up very naturally. The ride is relatively comfortable. It takes the edge off of most pavement imperfections, but you feel more than you might expect. So the Dodge Challenger GT has the style, space, and a decent balance of sportiness and comfort — which just leaves one thing left to address, the powertrain. And as it turns out, the V6 actually works quite nicely in the big Dodge. Under full throttle, you get an angry, throaty honk from the intake that, while not as smooth and classic as a V8, is still fairly satisfying. It also has more than adequate acceleration, if not exhilarating. It's a combo that makes not only a fun affordable GT car, but just a solid commuter with an extra dose of style. The only caveat is that if you need something more truly sporty, you may still want to look at a Camaro or Mustang. Associate Editor Reese Counts: I spent the latter half of last week in Idaho and Wyoming driving a pretty sweet Nissan 370Z in the snow. That car was equipped with tracks and skis and allowed me to do some pretty dumb things with few repercussions, though it was one of the loudest and most uncomfortable cars I've ever driven. Coming home to Detroit and a Destroyer Grey Challenger GT was a very nice change of pace. The thing is, this car is still plenty capable in the snow. I like the Challenger quite a bit, especially in the bonkers Hellcat and Demon guise. But not everyone needs a 700-plus horsepower brute that guzzles gas with a nearly unequalled thirst. The Challenger GT checks a lot of boxes. It looks good, it's comfortable, roomy and thanks to all-wheel drive, genuinely usable year round.

2019 Dodge Challenger SRT Hellcat is getting a meaner hood

Though we weren't really worried Dodge would discontinue it, we're glad to hear the Dodge Challenger Hellcat will continue into the 2019 model year. It's also getting some updates for the new year, as shown in these teasers from Dodge. The biggest one we can see is the hood, which trades the relatively subtle center scoop and dual heat extractors for a pair of big angry nostrils. Dodge says the twin hood scoops are a throwback to past Dodge performance models, take the Dart Swinger, for example. They also bring to mind some mid- to late-2000s Pontiacs, but we'll try to focus on the classic Mopars. A little bit of Photoshop work helps highlight some other aspects of the 2019 Challenger Hellcat. The Hellcat Widebody will clearly continue for the new year, too, as the vehicle in the teaser image has the bulging arches found on that Challenger as well as the one-year-only Demon. We can also make out five-spoke wheels that may have split spokes. Most of the body looks like the current model, too, so we don't expect any major changes to the chassis or powertrain. The only other information Dodge revealed about the 2019 Challenger is that more information will come this summer. So expect to hear more in just a few months.
