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

Lightly-camouflaged Alfa Romeo Stelvio snapped testing

With the Alfa Romeo Stelvio's expected reveal date at the Los Angeles Auto Show quickly approaching, we're not surprised to see prototypes testing in broad daylight with less and less camouflage. But even these latest spy shots make it difficult to determine details about the upcoming SUV. Just like before the headlights are disguised by heavy tape, but appear to be nearly identical to the ones found on the Giulia sedan. There's also a small v-shaped grille at the front with two rectangular ones on the bottom of the front fascia. The hood has three oddly-shaped ridges, but those are probably more camo to disguise actual creases. Previous SUVs were spotted with much smaller ruffles on the hood. The overall profile of the prototype remains the same as the ones we've spotted earlier with a design that mimics the Porsche Macan. The bulbous rear end of the SUV hasn't changed much either. The familiar taillights are still taped off, but appear to be taken straight from the Giulia. The massive exhaust tips, though, are new and would be more at home on a sports car. With the Stelvio expected to get the same gasoline and diesel powertrains as the Giulia, the weapon-sized exhaust tips on the prototype hint towards the possibility of the SUV getting the 2.9-liter V6 from the Giulia Quadrifoglio.

Marchionne threatens to move Alfa production out of Italy

Fiat CEO Sergio Marchionne was unsurprisingly frank when asked by reporters about potential investments in Italian manufacturing for Alfa Romeo and Maserati, giving the Italian government the ultimatum, "Italy should decide if they want [Alfa Romeo's relaunch] to happen here or not as Fiat and Chrysler have several alternatives." Them's fightin' words.
Fiat's issue with the government stems directly from its courtroom clashes with the Fiom labor union. The two are currently embroiled in proceedings over longer shifts and shorter breaks, as Fiom has so far refused to sign a new contract citing revised labor laws that it says are anti-union.
According to Bloomberg, Fiat will be spending over $2.5 billion on development of eight new Alfas and six new Maseratis, in a bid to wrest some of the luxury pie away from BMW, Mercedes-Benz and Audi. But that's only going to happen if the government is willing to play ball and make life easier on Fiat.
