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

2019 Dodge Challenger SRT Hellcat Redeye Drivers' Notes | Wide awake

Editor-in-Chief Greg Migliore — I've always wondered how Dodge would evolve the Challenger. There was only one real generation, not counting the rebadged Mitsubishi. Past and present, it's always looked the same. With the Hellcat, Demon, and now my personal favorite, the Hellcat Redeye Widebody, it makes total sense. There's no need to redesign it every few years. Just tweak it and add cool features — like flared fenders and the 797-hp Hellcat engine. It's all you need. This thing makes a statement. The Redeye is the car your neighbors want a ride in. I parked in our office building's basement, and co-workers heard me gunning the engine — two stories up. It's a growl. It has bass. It's angry. It gets a little metallic sometimes, depending on how and when you lay on the gas. I launched fairly hard at every traffic light. Sometimes I'd rev at idle. The Monroney that came with our test car lists the fuel economy as zero (it actually gets 13 city and a respectable 22 highway). But still. You get the point. I've always liked how the Challenger drives. It's big. It's heavy. The hood looks like the deck of an aircraft carrier. It's not trying to be a track rat. Go fast in a straight line. That's what you do. Take a hard left and maybe you skid a little bit. Maybe that's the idea. You don't eat cheeseburgers because they're good for you. You eat them because they taste good. Hey, cheeseburgers have protein. And vitamins. Healthy isn't the right description, but there are some benefits. The same reasoning applies to this Challenger. The interior is attractive, well-furnished and comfortable. The leather-trimmed seats are supportive. I love the saddle brown color. I used to say the coupe's low roof and bulky A-pillars were a problem. Then I got over that. You're driving nearly 800 hp, so sit up and be on your toes. The trunk is huge, too. I could have put a car seat in the back, had I needed to. You can live with the Challenger. And the Redeye is perhaps the best version yet. The starting price is about $60 grand. That's a steal. The price of our tester is $92,290. That's insane. The $6,000 widebody pack is the thing I'd recommend most out of all the options. Get the nice leather, too. This content is hosted by a third party.

China-FCA merger could be a win-win for everyone but politicians

NEW YORK — Fiat Chrysler boss Sergio Marchionne has said the car industry needs to come together, cut costs and stop incinerating capital. So far, his words have mostly fallen on deaf ears among competitors in Europe and North America. But it appears Marchionne has finally found a receptive audience — in China. FCA shares soared Monday after trade publication Automotive News reported the $18 billion Italian-American conglomerate controlled by the Agnelli family rebuffed a takeover from an unidentified carmaker from the Chinese mainland. As ugly as the politics of such a combination may appear at first blush, a transaction could stack up industrially, and perhaps even financially. A Sino-U.S.-European merger would create the first truly global auto group. That could push consolidation to the next level elsewhere. Moreover, China is the world's top market for the SUVs that Jeep effectively invented, so it might benefit FCA financially. A combo would certainly help upgrade the domestic manufacturer; Chinese carmakers have gotten better at making cars, but struggle to build global brands, and they need to develop export markets. Though frivolous overseas shopping excursions by Chinese enterprises are being reined in by Beijing, acquisitions that support the modernization and transformation of strategic industries still receive support, and the government considers the automotive industry to be strategic. A purchase of FCA by Guangzhou Automobile, Great Wall or Dongfeng Motors would probably get the same stamp of approval ChemChina was given for its $43 billion takeover of Syngenta. What's standing in the way? Apart from price (Automotive News said FCA's board deemed the offer insufficient) there's the not-insignificant matter of politics. Even as FCA shares soared, President Donald Trump interrupted his vacation to instruct the U.S. Trade Representative to look into whether to investigate China's trade policies on intellectual property. Seeing storied Detroit brands like Jeep, Chrysler, Ram and Dodge handed off to a Chinese company would provoke howls among Trump's economic-nationalist supporters. It might not play well in Italy, either, to see Alfa Romeo and Maserati answering to Wuhan instead of Turin — though Automotive News said they might be spun off separately. Yet, as Morgan Stanley observes, "cars don't ship across oceans easily," and political considerations increasingly demand local manufacture of valuable products.
