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

This Alfa Romeo Giulia shows why its owner scored a job at Singer Vehicle Design

The original Giulia may not have been the most beautiful Alfa Romeo ever built, but it was one of the coolest. It was built at two different locations in Milan from 1962 through 1978, and as squared-off as it is, it still has an enduring sense of style. No wonder Alfa is planning on reviving the nameplate, just as it did with the Giulietta. It's just the kind of car that a video series like Petrolicious was born to profile, and that's why it's the subject of this latest episode. This particular 1970 Giulia 1300 Ti belongs to one Dorian Valenzuela, who bought it on Craigslist and modified it just the way he wanted – and to beautiful effect, we might add. In fact, we weren't the only ones who were impressed with Dorian's work, either: the job he did on the Giulia lead him to land a job with Singer Vehicle Design, purveyor of spectacularly reimagined Porsche restomods.

2015 Alfa Romeo 4C Spider doffs its cap in Detroit

With the debut of the 2015 Alfa Romeo 4C Spider the Italian company's US lineup has officially doubled. Cosmetically, it makes most of its changes up top and out back, starting with its exposure to the sky. The 4C's 236-pound carbon-fiber monocoque was already engineered for open-air duty, so the Spider only needs an aluminum rollbar underneath the CF roll hoop - called a "halo" - as well as some new upper body brackets and a crossbeam in the engine compartment to maintain stiffness. The CF windshield frame is both bolted and glued to the monocoque. When it's time to close the cabin off, a stowable cloth roof or, later after launch, an available carbon-fiber hardtop will do the job. We've already had the chance to affix and remove the former, and it's a simple job that's good for a full 160 mph, unlike some rival's similar toupees that aren't approved for top-speed runs. When we saw spy shots of the 4C Spider on a photo shoot recently, we thought the center-mounted exhaust from the concept car had been retired, but that's not the case. Buyers will have the option of a center-set Akrapovic titanium dual-mode exhaust, with a carbon-fiber body surround. The aural sensations will be boosted further with three air extractors in the new decklid. The cockpit comes standard with cross-stitched leather in either black, red or Tobacco, depending on package. Details include CF vent surrounds, and an Alpine stereo with plenty of media input options (we're hoping it's better than the absolutely terrible head unit we've already experienced in the 4C coupe). Exterior touches will be enhanced by four new wheel designs in silver or dark finish, with four choices of brake caliper. How much performance will you give up to go topless? It doesn't look like much, if any. The 4C Coupe has been run from standstill to 60 miles per hour anywhere from 4.1 seconds to 4.3 seconds. Alfa gives the estimated time for the Spider as 4.1-seconds, to go along with 1.1 g of lateral acceleration, and says the car only weighs 22 pounds more than its fixed-head sibling. It looks like the Spider is out to earn all the attention it's going to get when it launches this summer. You can turn your attentions now to the mega gallery above and the lengthy press release below, and we'll have live shots of it from the Detroit Auto Show shortly.
