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 Tonale will finally be revealed in February

Following a couple of delays, the Alfa Romeo Tonale compact SUV will finally, officially be shown to the public. The big reveal date is February 8, 2022, at 9:00 a.m. eastern time. The Tonale was first shown in concept form at the 2019 Geneva Motor Show. The production model was expected to be shown sometime last year, but a couple issues prevented that. Reportedly, Alfa's CEO wasn't happy with how the plug-in hybrid system was working. Then, the same chip shortages that have affected almost every manufacturer of high-tech equipment further delayed the SUV. The photos you're looking at above come via a supposed leak at a design clinic from a couple years ago. We're expecting the Tonale to be fairly closely related to the Jeep Compass, and it will use versions of the plug-in hybrid system that's available on the Jeep in Europe. Two different output variants will probably be offered, one with 190 horsepower and the other with around 240. The model will be an important addition to Alfa's small lineup, particularly in a popular SUV form factor. Related Video:

Alfa Romeo Giulia, Stelvio Quadrifoglio get louder and — literally — greener

Alfa Romeo made several small improvements to the Quadrifoglio variants of the Giulia and the Stelvio as part of its 110th birthday celebrations. The changes make both models safer, more stylish, and quite a bit louder. Outside, the design tweaks are largely limited to new-look LED rear lights with darker lenses and 21-inch alloy wheels for the Stelvio. The color palette grows with the addition of three new hues called 6C Villa d'Este Red, GT Junior Ocra, and Montreal Green, respectively. They're heritage-laced colors that dyed-in-the-wool Alfisti will immediately recognize; the green is a tribute to the V8-powered Montreal released in 1970, for example. Step aboard, and you'll notice there's a redesigned center console that stylists carved additional storage space into, a new steering wheel, plus additional upholstery choices. Sparco sport seats built around a carbon fiber shell are waiting on the list of options along with red and green seatbelts. The updated infotainment system we've already experienced in the standard Giulia has found its way to the Quadrifoglio, too. It's displayed on an 8.8-inch touchscreen and Alfa Romeo added a feature called Performance Pages that shows a wealth of drivetrain-related parameters like the turbo pressure, the amount of power generated in real-time, and a chronometer. If these digital features sound familiar, it's likely because some Dodge models — including the Challenger — are already available with the Performance Pages app. We like it there, and we'll certainly enjoy Alfa's spin on it. Bosch helped Alfa Romeo add a panoply of electronic driving aids to the Giulia and Stelvio. The list includes lane-keeping assist, adaptive cruise control, active blind spot assist, traffic sign recognition, and traffic jam assist. The suite corresponds to level two on the SAE scale so it doesn't turn either model into an autonomous car. There are no mechanical changes to report, meaning power still comes from a 2.9-liter V6 that relies on a pair of beefy turbochargers to make 505 horsepower and 443 pound-feet of torque. It spins the rear wheels via an eight-speed automatic transmission, and pelts the Giulia from zero to 60 mph in 3.8 seconds before sending it to a 191-mph top speed. The same six powers the bigger, heavier Stelvio, but it channels its power to the four wheels. Enthusiasts who want to be heard before they're seen are in luck.
