Mopar unveils Dodge Challenger Drag Pak [w/video]

Dodge is going drag racing, and it's doing it with an all-new version of the Challenger for NHRA's Sportsman class. FCA's Mopar parts and performance arm announced the new Challenger Drag Pak Friday, showing off a version with a 354-cubic-inch (that's a 5.8-liter, by the way), supercharged V8 and a 426-ci (7.0-liter), naturally aspirated V8 – both Hemis, of course – that can get the big coupes through the quarter-mile in "the eight-second range." While the two engines deliver similar performance, at their base, they're quite a bit different. The supercharged model uses a cast-iron block, while the 426 has aluminum for both the block and head. That said, both models get customized engine calibrations, and are mated to unique, race-spec automatic transmissions. But drag racing is about far more than just outright power. Mopar significantly updated the four-link rear suspension, adding a four-inch rear axle from Strange Engineering, along with an aluminum, nine-inch third member, while the rear-axle housing has been strengthened in general. Both the rear shocks and front struts can be adjusted for rebound and compression, too. Lightweight 15-inch wheels, meanwhile, are shod in super-sticky Hoosier drag radials, with nine inches of tread in back and 4.5 inches in front. The new Challenger Drag Pak should run the quarter-mile in "the eight-second range." In the cabin, there's an NHRA-spec roll cage, a Racepak gauge cluster, and a handsome pair of Sparco racing seats. Outside, supercharged models get blue decals, while naturally aspirated varieties get black stickers, although there's more to the new Challenger dragster's exterior than just its decals. Mopar tweaked the big-scoop hood, promising it's easier to get up to check on the engine, and the designers also added trailer tie-down straps in both the front and rear. While the dragster was the big news today, Mopar officials also announced the two enhanced Scat Pack kits for both the Dodge Charger and Challenger R/T. The 5.7-liter Hemi models gain an extra 56 horsepower and 30 pound-feet of torque in the Scat Pack 2 thanks to a new cam, valve springs, pushrods, and gaskets. The Scat Pack 3, meanwhile, adds 75 hp and 44 lb-ft, on top of the gains from the lower packages. That should be perfect for drivers who wish to snort in the face of their SRT 392-driving friends. The third stage adds a ported cylinder heads, as well as high-flow manifolds and catalysts.

The final-year Viper special editions sold out so fast Dodge is adding more

Viper collectors don't mess around. After Dodge opened ordering for its 25th anniversary 2017 Viper models – some of the last ones that will be built – all of the cars were spoken for in just five days. The company managed to sell 206 cars, an average of about 41 per day. Compare that to the 241 Vipers sold through May of this year and you can see why special editions make good business sense. Demand was so strong that Dodge will add a sixth special-edition for the Viper's last year of production. Within the group of five initial special packages, the winner was the 1:28 Edition ACR; all 28 went in 40 minutes. Dodge sold the 31 VooDoo II Edition ACRs in two hours, while 25 Snakeskin Edition GTCs and 100 GTS-R Commemorative Edition ACRs took two days to sell out. The 22 Dodge Dealer Edition ACRs took five days – apparently the dealers were too busy taking orders for the other 184 cars they didn't have time to order their own. The additional anniversary car is called the Snakeskin ACR. Dodge will build "up to" 31 of them, which we're pretty sure means exactly 31 if the previous demand is any indicator. The count matches the 2010 run of Snakeskin ACRs and will take the final-edition total to 237. We don't have any photos of that one yet, but you can get a good idea of what it will look like from the Snakeskin GTC. This one features Snakeskin Green paint, obviously, with a custom snakeskin-patterned SRT stripe, the ACR Package, the Extreme Aero Package, carbon-ceramic brakes, the ACR interior, a serialized Snakeskin badge on the instrument panel, and a custom car cover with the owner's name by the door. It will be available to order in the middle of this month, which means it will be sold out well by the end of the month. Chances are these and many of the others will go to mega-collectors like Wayne and D'Ann Rauh of Texas, who, at last count, owned 79 Vipers. Seventy-nine. Like we said, Viper collectors don't mess around. Related Video:

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
