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

2022 Alfa Romeo GTV leaked image shows high performance coupe

Update: Turns out, the image came from the School of Design Milan and is not a leaked image of the upcoming Alfa GTV. We have since learned the image was of a rendering presented during a class. Alfa Romeo declared it was going to bring back the GTV name with a high-performance hybrid car last summer at its five-year plan conference. We got a teaser then, but now this image has surfaced online, initially appearing on the Italian Club Alfa website. It does indeed have the coupe bodystyle we surmised before. We're getting a grand tourer vibe from the styling right now, especially in knowing Alfa plans on giving the GTV 600 horsepower. The power will most likely come from the 2.9-liter twin-turbo V6 hooked up to some form of hybrid electric system. We've been told to expect all-wheel drive, torque vectoring and a 50/50 weight distribution for the GTV, along with a short electric-only range. Alfa's Giorgio platform was designed with electrification in mind, so this car will certainly ride on those underpinnings. That's great to hear, because the Giulia and Stelvio are both dynamic standouts in their respective classes. This car's looks looks set to take on other luxury grand tourers like the Lexus LC500 and BMW 8 Series. The GTV is set to be joined by a new 8C supercar with even more horsepower in 2022. That vehicle will also be using a hybrid powertrain. Both these cars are still a few years from production, but we may just see a concept or two at auto shows leading up to their eventual reveals.

Leno samples Corvette Z06, steam cars, supercars and the wonders of Pebble Beach

While Jay Leno's Garage was conceived to highlight the wonders of The Big Chin's eponymous storage facility, Leno does occasionally get out an into the larger world. Pebble Beach and the festivities around Monterey recently provided a great excuse for a road trip, and Leno seemingly had a pretty full dance card.
In an episode aptly dubbed The Ultimate Car Week, our host takes us through a pretty representative selection of great things to see in and around Pebble. Starting with a ride-along in a steam car, Jay manages to check in on the latest McLaren supercar and drive the Alfa Romeo 4C along the way. Oh, and he takes a good look at the all-new Corvette Z06 (next to the original Z06) before hitting the Concourse d'Elegance, too.
