Hellcrate 6.2-liter V8 delivers plug-and-play Hellcat hype to SEMA

SEMA just provided another entry for the folder marked "What A Time To Be Alive," with Mopar's announcement of the "Hellcrate" 6.2-liter supercharged Crate HEMI engine. Enthusiasts have been desperate to upgrade their vintage rides with the woozy thrills provided by Dodge's Hellcat motor, so Mopar answered. The Hellcrate engine assembly ships in plug-and-play configuration, in specially designed packaging with "Hellcrate" logos. The assembly sells separately from the Hellcrate engine kit, the kit adding a powertrain control module, power distribution center, engine wiring harness, chassis harness, accelerator pedal, ground jumper, oxygen sensors, charge air temperature sensors, and fuel pump control module. The PCM comes programmed with the production-car engine's 707 horsepower and 650 pound-feet of torque. An optional front-end accessory drive kit contributes peripherals like alternator, power steering pump, belts, and pulleys. Don't bother trying to lash up a sleeper 1997 Chrysler Sebring, though; Mopar tuned the Hellcrate for pre-1976 vehicles and manual transmissions. The engine assembly retails for an MSRP of $19,530, and the kit wants a further $2,195. Mopar didn't announce pricing for the accessory drive kit. The engine and kit come with a three-year, unlimited-mileage warranty when bought together. The Mopar Hemi Crate website will be happy to take your orders as of now. For help envisioning the possibilities, stop by Fiat Chrysler's 15,345-square-foot SEMA booth to check out the Limelight Green, Hellcrate-powered 1970 Plymouth Superbird clone worked up by Mark Worman of Velocity's " Graveyard Carz." While you're there you might as well peep Worman's encore, a 1968 Plymouth GTX stuffed with Mopar's 392 Crate HEMI in place of the original 440 big block, and the 1937 Dodge pickup that swallowed a Mopar 345 Crate HEMI. Mopar's come a long way from its original product: antifreeze products. Tomorrow it'll be Jeep's turn to ring the SEMA bells, once the noise dies down from the Mopar-jacked Wrangler Switchback, CJ66 and Jeep Shortcut. You can watch the brand's presentation online at 7:26 p.m. ET/4:26 p.m. PT. Until then, we're going to work the angles on a Hellcrate-powered Plymouth Volare. The sedan, naturally. Because we're practical. Related Video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

Tier 1 suppliers call GM the worst OEM to work with

Among automakers with a big US presence, General Motors is the worst to work for, according to a new survey from Tier 1 automotive suppliers, conducted by Planning Perspectives, Inc.
The Detroit-based manufacturer, which has been under fire following the ignition switch recall and its accompanying scandal, finished behind six other automakers with big US manufacturing operations. Suppliers had issues with trust and communications, as well as intellectual property protection. GM was also the least likely to allow suppliers to raise their prices in the face of unexpected increases in material cost, all of which contributed to 55 percent of suppliers saying their relationship with GM was "poor to very poor."
GM's cross-town competitors didn't fare much better. Chrysler finished in fifth place, ahead of GM and behind Dearborn-based Ford, which was passed for third place this year by Nissan. Toyota took the top marks, while Honda captured second place.

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
