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

2023 J.D. Power Initial Quality Study shows there's less quality than last year

Vehicle inventory, vehicle pricing, and the supply chain are finally showing improvement. Vehicle quality, on the other hand, is still going the wrong way. That's the takeaway from the 2023 J.D. Power Initial Quality Study that found overall problems exceeded last year's record high. The study surveyed owners of 2022-model-year vehicles to assess the average rate of problems per 100 vehicles (PP100) during the first 90 days of ownership. The average figure for the 32 ranked manufacturers in 2020 was about 166 problems per 100 vehicles. In the 2021 IQS, that dropped to an average of 162. For 2022, the average jumped to 180 problems. For 2023, the PP100 is up to an industry average of 192 — an increase of 30 problems per 100 vehicles in just two years. Let's get to the good news first: Dodge reclaimed the crown of having the lowest number of problems per 100 vehicles at 140. Buick won last year with 139 PP100, falling to third this year. Dodge was the first American automaker to top the IQS in 2021. Its return as the least problematic gives parent company Stellantis three wins in four years after Ram was crowned in 2021. It also gives U.S. brands a four-peat after Buick topped the chart in 2022 by having owners report the fewest problems. This year's top 10 is Dodge, Ram, Alfa Romeo, Buick, Chevrolet, GMC, Porsche, Cadillac, Kia, and Lexus. Stellantis gathered a few feathers for its cap, in fact. Maserati showed the largest improvement year-on-year, followed by Alfa Romeo, and Alfa Romeo posted the lowest PP100 among the premium class, beating Porsche and Cadillac. Alfa Romeo has been vocal about working to improve quality, mentioning Lexus as a target. Last year the Japanese brand finished sixth, the Italians finished near the bottom, between Jaguar and Mitsubishi. This year Alfa jumped to third, Lexus dropped to tenth. Ram was the third-best on the list of improvers from 2022 to 2023.   The individual model with the lowest PP100 is the Nissan Maxima. Now for the troublesome bits. In the words of Frank Hanley, senior director of auto benchmarking at J.D. Power, "The industry is at a major crossroad and the path each manufacturer chooses is paramount for its future.

2024 Alfa Romeo Giulia and Stelvio Quadrifoglio Super Sports close the book

Alfa Romeo is hitting the gas on limited-edition special-edition models of late, as the Italian outfit prepares to get rid of gas entirely. Last year we got the Giulia and Stelvio Quadrifoglio 100th Anniversario editions celebrating the centenary of the four-leaf clover trims, then came Quadrifoglio Carbon Editions celebrating that resin weave, then came Tributo Italiano Editions lauding the home country. Now that the world is closer to the end of the internal combustion Quadrifoglio lineup, Alfa's launched the 2024 Giulia and 2024 Stelvio Quadrifoglio Super Sport models. The Giulia Quadrifoglio Super Sport is limited to 275 units worldwide, 72 coming to the U.S. The Stelvio Quadrifoglio Super Sport is even more limited, rolling out just 175 examples for the world, 52 slated for U.S. purchase. Both are powered by the brand's twin-turbo 2.9-liter V6 making 505 horsepower and 443 pound-feet of torque, shifting through an eight-speed automatic to both axles. It would have been wonderful to get the upgraded engine making 520 hp and the mechanical limited-slip differential offered on the 100th anniversary models, especially since the Super Sports are only priced $140 (Giulia) and $660 (Stelvio) below the centenary editions, but it's not to be. Instead, the Super Sports are enhanced outside with a black Quadrifoglio badge, carbon fiber mirror caps, carbon fiber accents in the grille shield, black Brembo calipers, and dark five-hole wheels that are 19 inches on the Giulia, 21 inches on the Stelvio. Inside, special trim includes red carbon fiber on the instrument panel, center console, and door cards, embroidered headrests, and a steering wheel wrapped in leather and Alcantara.  Designers prepped three exterior color options for the Giulia: Bianco Alfa, Metallic Nero Vulcano, or "Three-layer" Rosso Etna. The Stelvio can be had in one of the latter two, not the Bianco Alfa. The 2024 Giulia Quadrifoglio Super Sport starts at $88,365 after the $1,595 destination charge, representing a $5,400 premium over the standard model. The $95,965 Alfa Romeo Stelvio Quadrifoglio Super Sport runs a stiff $7,000 above the standard four-leaf SUV. Orders are open now, deliveries expected in the fall of this year.
