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

FCA adds 88k Dodge Challengers to Takata inflator recall

The Takata airbag inflator recall from FCA US is growing 88,346 vehicles larger in the US after the company's discovery of the faulty parts in the 2008-2010 Dodge Challenger. The affected examples have production dates between September 19, 2007, and October 29, 2010, and the coupes need the replacement components on the driver's side. According to chronology posted by the National Highway Traffic Safety Administration (as a PDF), the automaker was auditing the models covered under the campaign in July and "identified a population of vehicles that was inadvertently excluded." Initially, FCA believed these cars were using an unrecalled Takata inflator. The audit revealed that the affected cars indeed used a recalled version. As with the rest of the faulty parts, exposure to moisture can cause them to ignite too quickly during an airbag deployment and spray shrapnel at occupants. The problem has been linked to at least eight deaths worldwide and a vehicle fire in Japan. The Challenger wasn't previously part of FCA's 3.3-million unit national campaign or the subsequent expansion. According to FCA US the parts to complete the repairs in these Challengers aren't currently available. However, owners will be notified of the issue by mail starting August 14. They will receive a second notice when the parts become available.

The affected vehicles are equipped with a dual-stage driver frontal air bag that may be susceptible to moisture intrusion which, over time, could cause the inflator to rupture. CONSEQUENCE: In the event of a crash necessitating deployment of the driver's frontal air bag, the inflator could rupture with metal fragments striking the driver or other occupants resulting in serious injury or death. REMEDY: Chrysler will notify owners, and dealers will replace the driver's frontal air bag inflator, free of charge. Parts to remedy the vehicles are not currently available. Interim notices will be mailed to owners beginning August 14, 2015.

Old vs. New: 2014 SRT Viper takes on upgraded 16-year-old Dodge Viper

It's easy to play the "Would you rather have a New X or an Old Y with a bunch of upgrades?" game more often than we care to admit, but the crew at Car and Driver have taken bench racing to the next level with their latest video. In it, the magazine pits a brand-new 2014 SRT Viper against a highly modified 1997 Dodge Viper GTS. There are 16 years between the time this particular GTS rolled off the production line and when the new car bowed, but that doesn't mean the old snake's owners have been sitting on their hands.
Thanks to a spate of modifications, the GTS offers up a better power to weight ratio than the new machine, but is that enough to overcome the technological leap forward represented by the 2014 Viper? We won't spoil it for you. You'll just have to check out the full clip below for yourself.
