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

Dodge Hornet supposedly snapped inside Alfa Romeo Tonale factory

It appears that someone in Stellantis' Pomigliano d’Arco Assembly Plant in Italy couldn't keep their cellphone to themselves. Video uploaded to the Alfa Romeo Club Italia Facebook page, then quickly removed, purports to show Dodge's brand-engineered version of the Alfa Romeo Tonale in the same factory where the Alfa will be built. The Dodge is expected to be called the Hornet, and there are a few differences between it and and Alfa Romeo, which is understandable. But if the screenshots on Twitter are accurate, then the Dodge looks a lot closer to the Alfa Romeo than perhaps anyone expected. The front fascia and hood fall in line with Dodge's design language. The Alfa grille is replaced by a narrow, stepped upper grille, and the hood is one of the vented units similar to those available for Dodge's R/T performance trims. And as Mopar Insiders noticed, the silhouette of this car's front end matches a vehicle silhouette Dodge showed during Stellantis' 2021 EV Day.   Inside, the Italian brand's crest in the steering wheel center cap is replaced by Dodge's twin slashes, and the steering wheel has been stripped of the large, curved paddle shifters the Tonale showed on its debut. There's still a start/stop button on the steering wheel, but where the Tonale has a driving mode dial on its dash, this supposed Hornet has another start/stop button. Dodge's push-to-start buttons are usually on the instrument panel, so our guess is that the wheel is a holdover for testing. On the center tunnel, the parking alert buttons and Italian Tricolore flag on the Alfa Romeo are replaced by three different buttons.   We've known Dodge has two electrified vehicles on the way, and the Hornet name has been low-key buzzing for two years. Fiat Chrysler applied to trademark the name in the U.S. in March 2020; at the time, it was thought a vehicle with that name could replace the Journey. In 2021, a July rumor out of Italy was the first whisper of the Hornet name being attached to the Alfa Romeo Tonale. In August, when Stellantis CEO Carlos Tavares said Dodge would get a PHEV in 2024, watchers pegged that model as the Hornet. That hybrid powertrain would show a year after the vehicle's launch, the Hornet anticipated as a 2023 model with the Tonale's turbocharged 2.0-liter four-cylinder. That engine could get the same 256 horsepower and 295 pound-feet of torque as the Tonale, or be boosted to satisfy Dodge's performance credentials.

Alfa Romeo's Giulia Quadrifoglio gets the GTA treatment

Alfa Romeo will celebrate 110 years of building some of the world's most emotional driving machines with a brand-new Giulia Quadrifoglio GTA. GTA, which stands for "Gran Turismo Alleggerita," is a throwback to the 1965 Giulia Sprint GT, which first got the treatment. The new GTA and GTAm will elevate the Giulia's already driver-friendly formula to a whole new level.  If the plain-Jane Giulia Quadrifoglio is a BMW M3 or Mercedes-AMG C63 competitor, the GTA is your Competition or "S" variant, respectively. It boasts more power, less weight, enhanced aero, a revised suspension, and a reworked chassis and interior designed to keep the driver in place and focused on one task and one task alone: driving fast.  The wick on the GTA's 2.9-liter twin-turbocharged V6 has been turned up a bit, resulting in a new peak rating of 540 horsepower (up 30 from the base car). To reduce weight, Alfa replaced a host of exterior panels with carbon fiber equivalents. The carbon treatment extends to some other components, such as a the drive shaft. Alfa says the net reduction works out to 220 pounds.  Outside, the aero has been completely revised with technical know-how provided by Sauber Engineering (of F1 renown). It also boasts 20-inch center-locking wheels and a titanium exhaust system. Alfa replaced many of the suspension bushings, the shocks and the springs with performance-friendly hardware. The GTAm pushes the formula even farther. We hesitate to compare a sport sedan to a GT Coupe, but the relationship between GTA and GTAm is quite similar to that between the Porsche 911 GT3 and GT3 RS. Both are fundamentally the same car, but the latter compromises a great deal more of its daily drivability for the sake of improving its on-track feel and performance.  With the GTAm, this included a set of carbon-backed front bucket seats with six-point harnesses, Lexan window inserts for the side and rear windows, and a rear seat delete. In place of the rear bench, you get a harness bar attached to a structural roll hoop, plus a handy little cubby for storing your custom Bell helmet in Alfa's GTA livery (which comes with the car, as well as an Alpinestars race suit, gloves and shoes, and a personalized Goodwool car cover). Checking in at just 3,350 pounds, the GTAm boasts a power-to-weight ratio of 6.2 pounds per horsepower, which Alfa says is the best in the class, enabling a 0-60 run in just 3.6 seconds.
