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

The new Alfa Romeo Giulia needs to be a BMW beater

The introduction of the Alfa Romeo Giulia as a BMW challenger is a claim that historically has meant that it will not be as good as a BMW. Mercedes, Audi, Lexus, Infiniti, Cadillac, and a few others have tried to loosen BMW's grip on the sports sedan market with little success. It was BMW that was doing the copying when in the early sixties they looked to Alfa Romeo's sport sedans for inspiration. Alfa Romeo's pre-war racing pedigree was second to none, and series production Alfas were sporting twin cam engines, and fuel injection years before BMW. What the post-war Alfa cars did not offer was reliability and an North American dealer network that knew how to service or sell their products. Consequently in 1995 Alfa abandoned the US market. Now it is the Alfa Giulia taking aim at the BMW 3-series. The Fiat/Chrysler group has a lot of resources (think Ferrari), and the engineering chops to beat BMW at its own game, but it will take a long time to build a reliable dealer network, not to mention the quality issues that have dogged them for decades. Alfa will follow what has become a familiar recipe to challenge the 3-series. With 3 sets of trim available, the most affordable model, the Giulia, and further upscale, Giulia ti, both with a turbocharged 4-banger and 276 HP compares favorably with the BMW 328i and the Audi A4. The 505 HP Giulia flagship is shooting for the M4/3. Good luck with that, Alfa. A delayed introduction hints of troubles to come. Unfortunately for Alfa both the Audi A4 and BMW 3-series have millions of dedicated fans, most of whom do not have to be reminded about their automobile's pedigree. Millennial have never had the chance to aspire for an Alfa, and the older generations that still remember them are only a very small share of the market. Alfa has to avoid joining the automotive graveyard of models that have tried to attain BMW's status. Just to be cruel I will mention the Cadillac Cimarron. If you are too young to remember, it was the cheapest Chevy front wheel drive platform with a Cadillac badge. Panned by both GM management and the automotive press, it was a spectacular flop. I hope that the executives of the Fiat/Chrysler group remember it well. We do not need a Fiat in a stylish suit.

Alfa Sprint Speciale racer looks fantastic, sounds even better

Nothing quite sounds like a vintage Alfa Romeo four-cylinder engine at full gallop, especially in motorsport trim. With a combination of low-frequency burbling played over a high-pitch scream, they really know how to sing. This week Petrolicious takes a look at a truly unique Alfa Sprint Speciale that's just as adept at competing in the wide-open La Carrera Panamericana vintage race in Mexico as it is snaking through some undulating, tree-lined back roads. Ostensibly, this is a 1965 Alfa Romeo Giulia Sprint Speciale, although it's really much more the creation of Alfa-restorer Conrad Stevenson. The roof section, including the holes for the windshield and rear glass, is original to one of these fantastic-looking coupes. But everything below that is Stevenson's handiwork. To shape the styling, he combined the original Bertone design with his own ideas to purpose build the car for the challenges of the Mexican race. As usual, Petrolicious nails every aspect of the production, especially the handheld camera work inside the cabin as the car negotiates the curves. It really communicates the connection between this swoopy Alfa and its builder. Plus, the sound mix lets the engine play its glorious tune.
