Chevy Corvette Stingray defeating rivals where it matters most

Everything is coming up roses for the award-winning Chevrolet Corvette Stingray, as new data from the North American Dealers Association dissected by GM Authority reveals that America's sports car is handily outselling two of its more expensive rivals.
Through June of 2014, the NADA notes that the Corvette has rung up 17,744 sales, handily besting the Porsche 911 and positively spanking the SRT Viper. Of course, you're sitting there thinking, "Corvette is outselling the much more expensive Porsche and Viper. Sky blue, water wet." But what's impressive here is just how thoroughly the Chevrolet is beating its two rivals, with this data serving as a testament to just how popular the seventh-generation sports car has become.
So far this year, Porsche has managed to move 5,169 911s, according to NADA. Considering that the base model starts at nearly $15,000 more than the most heavily optioned Stingray, and that Porsche owners have a vast, expensive options catalogue to select from, Stuttgart's sales are still plenty impressive in relation to the nearly 18,000 Corvettes sold.

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 performance trio thrashed on Roadkill

Of all the shows that Motor Trend does, Roadkill is probably the last one we'd pick to evaluate the latest performance automobiles. That's not a slight against David Freiburger or Mike Finnegan, who host the show: they're certified gear-heads and the go-to guys when it comes to hot rods, rat rods and anything grungier than it is shiny. But as exemplary as they are of Detroit muscle, the Charger Hellcat, Challenger Hellcat and Viper are also shiny new pieces of metal. Still, since it will now be sponsoring the show, someone at Dodge apparently thought it would be a good idea to hand Freiburger and Finnegan the keys to the company's top performance models. So to ring the best out of them, they solicited help from some of their colleagues at MT, gained access to a closed-down air strip, devised as many ways as they could to destroy the tires, and proceeded to set about doing exactly that. Watch the grin-inducing mayhem unfold in the half-hour clip above. Related Video:
