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

Dodge Charger Hellcat makes 1,032 hp with Hennessey help

Sometimes you just want four doors. Earlier this week we brought you Hennessey's riff on the Dodge Challenger Hellcat. Now comes the Charger. Much like its two-door sibling, the Charger gets boosted to as much as 1,032 hp and 987 lb-ft of torque (at the crank) thanks to the addition of a twin-turbocharging setup that works with the factory supercharger. The turbo headers and downpipes are stainless steel, and there is a high-flow air-to-water intercooler and dual-turbo waste gates. Hennessey also beefs up the fuel injectors, fuel pump, and the rest of the fuel system. The engine management system and chassis are recalibrated to accommodate all of this. You also get numbered plaques signed by John Hennessey, the boss of the Texas tuning outfit, and the technician who does your build. Hennessey's additions result in zero-to-60 mph sprints in 2.7 seconds, and the big sedan can run the quarter mile in 9.9 seconds at 142 mph. Like the Challenger, the Charger has the same disclaimer: the lofty horsepower figure comes from an engine dyno, and it will be a 15-to 20-percent lower at the rear wheels.

Dodge celebrates big B-day with 100th Anniversary Editions muscle cars

Being in business for 100 years is a HUGE milestone, so we hope Dodge has more in mind to celebrate its centennial than just a special edition package for the 2014 Charger and Challenger. Called the 100th Anniversary Edition package, this collection of cosmetic enhancements will be available in limited quantities for both cars at a cost of $2,500.
Ordering a Charger or Challenger with the 100th Anniversary Edition package means starting with either a V6-powered SXT Plus or V8-powered R/T Plus model. They can each be ordered in many colors, but only the High-Octane Red Pearl Coat above is an anniversary exclusive. Each car also comes with an anniversary-exclusive set of 20-inch, five-spoke wheels with what Dodge calls "Granite Crystal pockets," a texture that's also mirrored on each car's grille.
Of course, there are commemorative badges galore affixed to the exterior of each car, including "Dodge Est. 1914" fender badges and "100" logos on the center caps of each wheel. The styling theme of each car's interior is a bit more interesting, with Dodge designers trying to evoke "the patina and machinist legacy of John and Horace Dodge," the company's founders. To that end, the leather interior can be had in Molten Red or Foundry Black Nappa, and each features a custom cloud overprint that makes the hide look like a working man's dirty dungarees. Designers also used brass-colored accent stitching on the interior's leather trim pieces, and affixed more "Dodge Est. 1914" badges to the front seat backs and floor mats. We do like the flat-bottomed steering wheel, and the Challenger 100th Anniversary Edition gets exclusive white gauges faces and the Charger black. The "100" on each car's speedometer is also highlighted in red.
