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 Challenger spied exercising supercharged Hellcat Hemi V8

One of the prime complaints against the Dodge Challenger is that, even in SRT8 guise, its 470 horsepower is responsible for hauling over 4,200 pounds of vehicle. For comparison, the 420 hp in the Ford Mustang GT only has to deal with 3,618 lbs. Things only get worse from there, as the higher-performance variants of both the Mustang and the Chevrolet Camaro are far more powerful than an SRT8 without adding on much heft.
So what is Chrysler to do? The correct answer is add a whole lot more grunt to its hefty two-door and even the odds. That's where the all-new Hellcat engine comes into play. We reported on this engine in May, and suggested that the Hellcat, a supercharged powerplant based on a 6.4-liter V8, would easily generate 500 to 570 hp and could likely arrive boasting more than 600 ponies.
Chrysler's ace in its sleeve has now been spied testing, with a number of Hellcat-equipped Challengers running the potent new engine both in more urbanized areas and under the sun of Death Valley. The hoods on these testers have been raised to accommodate the engine, and that camouflage over the fascias of these prototypes is there to hide a larger air intake. We also note what appears to be a new split grille under wraps. As for power output, our spies are now suggesting a Viper-equalling 640 hp from the Hellcat-equipped cars.

China's Great Wall confirms its interest — in Jeep, or all of FCA

HONG KONG/SHANGHAI — Chinese automaker Great Wall Motor reiterated its interest in Fiat Chrysler Automobiles NV on Tuesday, but said it had not held talks or signed a deal with executives at the Italian-American automaker. China's largest sport utility vehicle manufacturer made a direct overture to Fiat Chrysler on Monday, with an official saying the company was interested in all or part of FCA, owner of the Jeep and Ram truck brands. Automotive News first reported the news, quoting Great Wall Motor President Wang Fengying as saying she planned to contact FCA to discuss acquiring the Jeep brand specifically. Those comments sent FCA shares higher but also raised questions over the ability of China's seventh-largest automaker by sales to buy larger Western rival FCA, or even Jeep, which some analysts value at as much as one-and-a-half times FCA. Great Wall sought to dampen speculation on Tuesday. It confirmed it had studied Fiat Chrysler, but said there was "no concrete progress so far" and "substantial uncertainty" over whether it would eventually bid. "The company has not built any relationship with the directors of FCA nor has the company entered into any discussion or signed any agreements with any officer of FCA so far," the company said in an English-language stock exchange filing. It did not give further detail. Fiat Chrysler stock dipped on the statement on Tuesday. Great Wall said trading in its Shanghai-listed shares would resume on Wednesday after having been suspended. Fiat Chrysler declined to comment on Great Wall's statement. On Monday, it said it had not been approached and was fully committed to implementing its current business plan. FLUSHING OUT RIVALS? Great Wall Motor, which was early to spot China's love of SUVs, had revenue of $14.8 billion last year and sold 1.07 million vehicles - but that compares with FCA's 2016 revenue of 111 billion euros ($130.6 billion). Analysts said Great Wall would need to raise both debt and equity to complete any deal, meaning its chairman Wei Jianjun could lose majority control. One possible scenario, according to analysts at Jefferies, would see Wei keeping a roughly 30 percent stake, while Great Wall would raise $10-$14 billion in debt and $10 billion in equity - hefty for a group currently worth just $16 billion. Ultimately, politics could be the clincher.
