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

How fracking is causing Chrysler minivans to sit on Detroit's riverfront

It's fascinating the way that one change to a complex system can have all sorts of unintended consequences. For instance, there are hundreds of new Chrysler Town and County and Dodge Grand Caravan minivans built in Windsor, Ontario, sitting in lots on the Detroit waterfront because of the energy boom in the Bakken oil field in the northern US and parts of Canada.
The huge amount of crude oil coming from these sites mostly use freight trains for transport, and that supply boom has resulted in a shortage of railcars to carry other goods. According to The Windsor Star, North American crude oil transport by train has gone from 9,500 carloads in 2008 to 434,032 carloads in 2013. Making matters worse, some North American rail infrastructure is still damaged because of this year's harsh winter, and that's slowing things down even further.
Chrysler admits to The Star that it has had some delivery delays due to the freight train shortage. In the meantime, it's using more trucks to deliver its vehicles. Trucking is a far less economical solution, partially because a train can carry so many more units at one time, but alternatives are slim. The Windsor plant alone has a deal for 33 trucks to distribute the minivans around Canada and the Midwestern US.

MotorWeek remembers a better time for Mitsubishi performance

Dodge still knows how to create an capable performance car – look at the Hellcats, for example – but the same isn't true for Mitsubishi. With the Lancer Evo's demise, we don't expect driving enthusiasts to clamor for any of the Japanese automaker's other products. Things used to be different, though. As MotorWeek found in its new Retro Review, the 1991 Mitsubishi 3000GT VR4 and its sibling, the Dodge Stealth R/T Turbo, were impressive sports coupes in their day. Dodge and Mitsubishi packed a bevy of cutting-edge tech into the coupes. In these trims, both sported all-wheel drive, four-wheel steering, an adjustable suspension, active exhaust, and automatic climate control. The 3000GT VR4 upped the ante even more with active aero parts at the front and rear. Their 3.0-liter twin-turbo V6 was good for 300 horsepower and 307 pound-feet, which were good numbers at the time. This pair put all their gizmos to good use, too. MotorWeek compares the all-wheel-drive system's grip levels to a Porsche 911 Carrera 4. When was the last time you heard any favorable similarity between a Mitsubishi and a Porsche? The Stealth R/T Turbo and 3000GT VR4 came from a special time for Japanese sports coupes, when every brand had a halo model. Whether you were looking at Nissan 300ZX, Mazda RX-7, Toyota Supra, or even the Acura NSX, there was a lot to like on the market. MotorWeek's latest Retro Review offers a great reminder of that period.
