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 4C will be refreshed for the 2019 model year

Alfa Romeo Chief Technical Officer Roberto Fedeli said at a launch event for the Stelvio Quadrifoglio that an updated version of the 4C is coming next year as a 2019 model. "We are coming back to Formula 1," he said, "and we need the 4C to be our halo car," Fedeli told Autocar. But don't expect to see the refresh bring with it a manual transmission. No future high-performance models from Alfa, Maserati, or even Ferrari will be getting clutch pedals anytime soon, a decision reportedly made after Ferrari spent 10 million euros developing a manual gearbox for the California a few years back only to see exactly two customers choose the option over an automatic. We'd hazard a guess that Alfa will tone down its carbon-fiber 4C for the next generation. As fun as the little sportscar is on a race track, it's equally jarring to drive on regular roads. A revised suspension and perhaps power steering may be on the menu. Related Video:

Alfa Romeo drops its Giorgio platform as it electrifies for the future

Alfa Romeo, a storied Italian automaker with a tremendous amount of goodwill from the automotive enthusiast crowd, is about to go through yet another major transformation. According to reports, including this one from Automotive News Europe, newly appointed Alfa Romeo CEO Jean-Philippe Imparato told Italian journalists during a roundtable event that all future vehicles from the company would be electrified and built on a new platform known internally as the STLA large-vehicle architecture that will be shared across brands under the Stellantis umbrella. "We are working on the Large platform of Stellantis and we will no longer use the Giorgio,” Imparato said. “We must take advantage of the volumes to take all possible opportunities and bring an EV range to Alfa Romeo, but always with the touch of Alfa Romeo.” That means the well-regarded Giorgio platform that currently underpins Alfa Romeo's only two mainstream products, the Giulia sedan and the Stelvio crossover, will come to an inglorious end. That's a shame. The Giorgio platform didn't just cost Alfa's previous parent company Fiat Chrysler Automobiles millions of dollars to engineer, it also gave the company a duo of vehicles that arguably drive better than anything else in their segments. Forbes reports that the Giorgio platform won't be entirely abandoned, as it will reportedly be integrated into the rest of the Stellantis portfolio in some way. We don't know exactly what that means, but perhaps it lives on in heavily modified form as the basis of crossovers and SUVs like the upcoming Jeep Grand Cherokee, which Jeep calls a completely new platform but one we believe shares engineering with the Giorgio. We also think it will underpin the upcoming Maserati Grecale. As for the future of Alfa Romeo, the next model coming from the brand is the Tonale, which was delayed by Imparato in order to get its plug-in hybrid powertrain just right. Tonale will use a platform shared with current Jeeps. Rumors suggest an even smaller crossover called the Brennero is on the way, also using a hybrid drivetrain. Past that, we'll just have to wait and see — Imparato says new 5-year and 10-year plans are currently being finalized. In any case, we doubt there will be any significant updates to the Giulia or Stelvio as the brand moves all its resources to its electrified intentions. Related video:
