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

Alfa Romeo Zagato-designed Giulia-derived coupe previewed

Alfa Romeo's long-awaited return to the coupe segment may be imminent. The company published an enigmatic preview image on its social media channels that shows the rear end of what's labeled the "Giulia SWB Zagato," and it pledged to release more details in the near future. While there's not much we can glean by looking at the dark teaser, we can at least say with near-certainty that the coupe won't look much like the Giulia when viewed from the back. The photo depicts a thin strip of LEDs that seemingly stretches across the entire rear end, and the basic silhouette is vaguely reminiscent of the Giulia TZ (Tubolare Zagato) and TZ2 coupes built in very limited numbers during the 1960s. Beyond that, your guess regarding what we're looking at is as good as ours. The name strongly suggests that the coupe will be Giulia-based, shorter than the sedan, and designed jointly with Zagato. Company boss Jean-Philippe Imparato has previously confirmed that the two-door model will make its debut at some point in 2023 and he clarified that it will be "very exciting, very selective, and very expensive." To us, it sounds like the coupe will land as a limited-edition model rather than as a regular-production addition to the company's range. What the coupe will be powered by is up in the air as well. Given the Giulia-derived platform, we wouldn't be surprised if power comes from a version of the 2.9-liter, twin-turbocharged V6 that powers the range-topping Quadrifoglio. The six develops 505 horsepower and 443 pound-feet of torque in Alfa Romeo's BMW M3 fighter but those figures could increase in the coupe. Rear-wheel-drive should come standard. Alfa Romeo will publish additional details about the Giulia SWB Zagato in the coming weeks, and we'll see the coupe by the end of 2023.

Alfa Romeo Tonale will finally be revealed in February

Following a couple of delays, the Alfa Romeo Tonale compact SUV will finally, officially be shown to the public. The big reveal date is February 8, 2022, at 9:00 a.m. eastern time. The Tonale was first shown in concept form at the 2019 Geneva Motor Show. The production model was expected to be shown sometime last year, but a couple issues prevented that. Reportedly, Alfa's CEO wasn't happy with how the plug-in hybrid system was working. Then, the same chip shortages that have affected almost every manufacturer of high-tech equipment further delayed the SUV. The photos you're looking at above come via a supposed leak at a design clinic from a couple years ago. We're expecting the Tonale to be fairly closely related to the Jeep Compass, and it will use versions of the plug-in hybrid system that's available on the Jeep in Europe. Two different output variants will probably be offered, one with 190 horsepower and the other with around 240. The model will be an important addition to Alfa's small lineup, particularly in a popular SUV form factor. Related Video:
