Dodge Charger Hellcat makes 1,032 hp with Hennessey help

Sometimes you just want four doors. Earlier this week we brought you Hennessey's riff on the Dodge Challenger Hellcat. Now comes the Charger. Much like its two-door sibling, the Charger gets boosted to as much as 1,032 hp and 987 lb-ft of torque (at the crank) thanks to the addition of a twin-turbocharging setup that works with the factory supercharger. The turbo headers and downpipes are stainless steel, and there is a high-flow air-to-water intercooler and dual-turbo waste gates. Hennessey also beefs up the fuel injectors, fuel pump, and the rest of the fuel system. The engine management system and chassis are recalibrated to accommodate all of this. You also get numbered plaques signed by John Hennessey, the boss of the Texas tuning outfit, and the technician who does your build. Hennessey's additions result in zero-to-60 mph sprints in 2.7 seconds, and the big sedan can run the quarter mile in 9.9 seconds at 142 mph. Like the Challenger, the Charger has the same disclaimer: the lofty horsepower figure comes from an engine dyno, and it will be a 15-to 20-percent lower at the rear wheels.

2016 Dodge Challenger and Charger Hellcats see doubled production

The launch of the Hellcat supercharged V8 in the Dodge Challenger and Charger for the 2015 model year was a massive success. The one-two punch of muscle cars probably grabbed the brand more headlines than it had seen in ages by offering a world-beating 707 horsepower from the growling engine under the hood. The only real wrench in the works was keeping up with all of the orders. For 2016, Dodge might have fixed that little problem with plans to make more than twice as many of these mean machines Despite production seeing a massive boost, a few customers with orders for 2015 examples will need to wait just a little longer to experience those 707 ponies. The automaker will cancel any unscheduled, sold orders for the current model, but those buyers will receive a discount on the 2016. Similar to last year, dealers will earn their allocation of the muscle cars based on Dodge sales and how long the Hellcats stay on their lots. There are some very tiny changes for any buyers who are holding out for the 2016 Hellcats, too. Mechanically, they are identical to the 2015s with a 6.2-liter supercharged V8 and eight-speed automatic. The interiors see some improvements, though. Both the Challenger and Charger now receive standard Laguna Leather upholstery and an improved 8.4-inch Uconnect system with navigation, an HD radio, and five years of SiriusXM Travel Link and Traffic. Orders for both open in the second week of August, and production actually begins in September in Brampton, Ontario, Canada.

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
