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

Chrysler's next-gen minivans will get more expensive

Chrysler introduced the value-oriented Great American Package on the base model Chrysler 300 in 2005. That morphed into the American Value Package available as an option on the Dodge Grand Caravan in 2012, which made it the lowest-priced minivan in the country, now with an MSRP of $21,395. Automotive News reports that Chrysler is going to kill the value package when the new Town & Country arrives for 2017, because the new platform and technology of the coming minivan make it "a difficult price point to get to." AN says the next-generation haulers will come in around $26,000 and can go beyond $45,000 with options; clicking every "Add" button we could find on the Town & Country build page, we couldn't get past $43,000 for today's model. That entry pricing in 2017 would eliminate the first three trims on the Dodge option, the American Value Package, the SE that starts at $24,195, and the SE Plus that starts at $24,995. This makes us think the next-generation haulers will take a sizable step upscale in terms of feel, content, and trim, a la the Chrysler 200. In this writer's opinion, if they do as good a job as they've been doing recently, the extra money will be worth it. There have been spy shots and a lot of rumors about it, like the Caravan minivan going away and becoming a crossover, but we'll see it revealed at the 2016 Detroit Auto Show.

Dodge Viper ACR reportedly green lit [w/video]

The Dodge Viper might be getting a little more venomous in the near future thanks to a return of the performance-honed ACR trim. According to an anonymous source leaking the info to Allpar, the version would go into production in July as a 2016 model year vehicle. FCA US showed a concept for a future ACR (pictured above) at the 2014 SEMA Show that sported carbon fiber parts for the front splitter and dive planes, plus a picnic-table-sized rear wing. The body also received ducts at the rear to shoot cool air to the differential. A set of 15.4-inch carbon-ceramic brake rotors also brought things to a halt in a hurry. The company promised all the aero pieces were sculpted in the wind tunnel to give the coupe even more downforce. To shed weight, engineers chucked the radio, speakers, carpet and sound deadening out of the interior, and they replaced many bits with even more carbon fiber. All of the tweaks are necessary because the ACR moniker carries serious cachet for the Viper at the track, especially at the Nurburgring. One reportedly did a 7:22 lap around the 'Ring in 2008, and another improved that further to 7:12 in 2011. Autoblog reached out to FCA US for comment about the possibility for the hotter Viper, but the company wasn't willing to comment about any possible, future projects. Related Video:
