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

The Dodge Demon's massive torque wrinkles its massive tires

Horsepower doesn't mean a damn thing if a car can't properly put the power down. That's why Dodge has fitted the upcoming Demon with some of the stickiest road-legal rubber available. Those Demon-branded Nitto NT05R drag radials skirt by regulations with just the smallest of margins, and in order to maximize the potential of the 315/40R 18 size tires Dodge increased the car's torque multiplication with a higher stall speed for the torque converter and a 3.09 rear axle. The 12.6-inch-wide tires are fitted to 18x11-inch wheels at all four corners, and they're fatter than those 305-section front tires on the Camaro Z/28 that we raved about years ago. Dodge says the combination of soft, gooey rubber and the new gear ratio gives the Demon about a 15 percent larger tire contact patch, more than twice as much grip, and roughly an 18 percent increase in both converter torque and rear-axle torque multiplication. Simply put, the Dodge Demon moves. You can see the results in the teaser video above, which is titles "Multiplication" and shows the crazy wrinkling of the sidewall that results from putting that torque to the road. We wouldn't be surprised if the inner rim of the wheel needs some grip to keep the tire seated, something Chevy had to do on the last Z/28. There is something wonderful about Dodge's approach to performance cars. While the Ford Mustang and Chevrolet Camaro have moved on from their muscle car upbringings with proper track-focused models, Dodge has stayed true to its roots by developing a machine that's sole intent is traveling a quarter-mile quicker than anything else on the road. Twisty roads may be fun, but there is something wholly and deeply satisfying about going deep into the accelerator with a comical amount of power at your disposal. We can't wait.

Dodge Charger SRT Widebody spied filming a commercial

The voice you hear in the video just below appears to be from Instagram user eviil_srt, and as you can tell, he's quite the Mopar superfan. Thing is, the car you see in that video appears worthy of such a fan's adoration. It's clearly a Dodge Charger Widebody, a vehicle that we've been anxiously awaiting ever since it was revealed in prototype form by Mark Trostle, head of design for Dodge and SRT, at Spring Fest 14. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Actually, we've been seeing hints of the wide Charger far longer than that – it was spotted testing on public roads before its officialish debut, and even prior to that, the car's rumored existence had the Internet rumbling with the force of a 700-plus-horsepower supercharged Hemi V8 for months. All that preamble brings us back to the present and the aforementioned Instagram post, in which this upcoming production Widebody was spotted presumably filming for an official television commercial debut. Note the body-color license plate on the Charger Widebody in the video, which indicates it's probably being used for an official purpose by Dodge. It's a short clip, but just long enough that we can clearly make out a big rear wing, vented bumper cover, and deep diffuser punctuated by large dual exhaust tips. We also see some extremely wide tires front and rear, which makes sense considering that there's very likely a whole corral's worth of ponies underhood. The current Dodge Challenger Widebody style is offered on the 485-horsepower R/T Scat Pack trim level, the SRT Hellcat trim level that bumps horsepower all the way to 717, and, for buyers who really hate their rear tires, the 797-hp Hellcat Redeye trim level. Dodge hasn't yet extended the excessively powerful Redeye engine to the Charger line, but the other two levels seem likely. And who knows – the Widebody's introduction might be the perfect opportunity to build a Charger Redeye. In any case, the fact that Dodge is filming commercials indicates that we won't have to wait much longer to find out for sure.
