2015 Dodge Challenger SRT Hellcat has 707 glorious horsepower [w/video]

Hold onto your butts. "600-plus horsepower" is what we were told to expect from the 2015 Dodge Challenger SRT with its 6.2-liter supercharged Hellcat V8 engine. But as we've just learned, those were incredibly conservative numbers. Dodge has officially announced that the range-topping Challenger will hit the asphalt with 707 - seven hundred and seven - horsepower, making it the "most powerful muscle car ever."
Of course, 707 hp is only part of the story, as the Hellcat has also been confirmed to produce 650 pound-feet of torque. All that power will run exclusively to the rear wheels through an eight-speed automatic transmission that differs from other Challengers. The new gearbox, 8HP90 (rather than the 8HP70) is "upgraded to handle the extra power and torque," says Dan Reid, SRT's manager of product design and motorsports.
We certainly hope you're prepared to spend a ton of money replacing tires.

Speedkore AWD twin-turbo Carbon Charger, best birthday gift ever

The backstory the Speedkore Performance AWD twin-turbo Carbon Charger teased a couple of weeks ago might be cooler than the car itself. Alan Palermo commissioned the carbon-fiber-bodied Dodge Demon Speedkore brought to SEMA last year, the one that supplanted the 6.2-liter Hellcat V8's supercharger with twin 6875 Precision Billet T4 turbos. That blasted the Demon's usual 840 horsepower up to 1,400 hp at the flywheel, 1,203 hp at the rear tires, good for an 8.77-second quarter-mile time at 162 miles per hour. Palermo's older brother remarked, "He liked the car but was more of a four-door guy," so Alan commissioned the AWD Carbon Charger as a 65th birthday gift for his sibling. Speedkore worked with Magnaflow on the sedan, starting with a 2019 Charger Pursuit as a base. The Wisconsin tuner secured a 2020 widebody Charger from Dodge, then 3D-scanned the bodywork to create the molds reproducing most of the sheetmetal in pre-preg carbon fiber. The hood, bumpers, fenders, rockers, rear spoiler, and rear diffuser are all fashioned from the lightweight stuff.  Beyond those Precision turbos laid in by Gearhead Fabrications, Speedkore installed a custom upper plenum, Boost Leash C02 progressive boost controller, custom Thitek heads, a Fore Innovations triple-pump fuel system feeding Injector Dynamics 1,700-cc injectors, and custom HP Tuners engine software calibration. Test results showed 1,525 hp at the crank when running 26 pounds of boost.  Hellraiser Performance engineered a new transmission working an FTI torque converter at one end and a carbon fiber driveshaft at the other. Instead of fortifying an off-the-shelf AWD system, Traction Products supplied a custom transfer case machined from billet shunting power to a set of Bogart Competition Series wheels wearing Mickey Thompson ET street rubber.  Speedkore fitted last year's Demon with a front-exit twin exhaust, with a single opening on each front fender, and left the rear bumper cutouts for the traditional exhaust empty. With the Carbon Charger sedan more of a family guy, Magnaflow sorted out a quad-pipe front-exit exhaust with two openings on each front fender, and ran a three-inch stainless steel Competition Series exhaust to the rear. The driver can switch between the two, the latter version providing a "moderate interior sound."  The folks at Speedkore say they'll keep tweaking the Carbon Charger after the show to get it right for the senior Palermo. We say, "Happy birthday, sir. Enjoy."

2019 Dodge Charger SRT Hellcat is getting a facelift

The Challenger Hellcat won't be the only Mopar muscle car getting an update for the new model year. One of our spy photographers caught an updated 2019 Dodge Charger SRT Hellcat testing near the SRT office. It appears that the car will continue on mostly unchanged, since everything behind the fenders is uncovered and unchanged. But the fascia must be getting some noteworthy changes considering how well it's hidden. And it's really, really well-hidden. It's extremely difficult to see through this covering. Whatever changes have been made still aren't going to be massive. It looks like the basics remain the same, including the large center grille in the bumper flanked by two outboard inlets that lack fog lights. The grille appears to still connect with the headlights, and the grille is pinched in the middle. Odds are, the front fascia is the only major difference on the 2019 Charger Hellcat, just as the twin-scoop hood on the Challenger Hellcat is the only major difference on that model. Under the hood will likely be the same 707-horsepower supercharged V8. This Charger prototype also sports the same Brembo brakes as the current model. The full reveal will probably come this summer along with the Challenger. Related Video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.
