2015 Dodge Challenger SRT Hellcat with '600-plus horsepower' officially unveiled [w/video]

Dodge has officially unveiled the most powerful vehicle to ever wear the Challenger name - the SRT Hellcat - complete with over 600 horsepower courtesy of a supercharged, 6.2-liter Hemi V8. It will be offered alongside the 485-hp Challenger SRT.
The new, force-induced V8 isn't just the most powerful ever fitted to the Challenger, it's the most powerful eight-cylinder Chrysler Group has ever built. Power figures aren't finalized, so expect to see "over 600 hp" bandied about quite a lot. That fury will be channeled through either a six-speed manual or eight-speed automatic. Yes, over 600 ponies through an eight-speed auto. So far, the only vehicle we know of that delivers more output through that many gears is the as-yet untested Chevrolet Corvette Z06. Sadly, we don't have performance metrics just yet, although if this thing can't crack four seconds to 60 miles per hour, we'll be pretty surprised.
As is the theme nowadays, the 2015 Challenger SRT features a number of driving modes, governing power output, shift speeds for the 8AT, steering effort, traction control settings and suspension settings. There are three pre-programmed options - Default, Sport and Track - and a Custom mode that allows drivers to mix and match to their heart's content.

Plymouth Rapid Transit System muscle car concepts going to auction

Over the past decade, Chrysler has built a reputation for amazing custom concept cars based on production vehicles for the SEMA Show and the Easter Jeep Safari. But the company's customization tradition has much deeper roots that include this collection of muscle car concepts headed for Mecum's Indianapolis auction this May. The collection includes three Plymouths that were featured in the traveling display called the Plymouth Rapid Transit System, and a Dodge that appeared at the 1969 Chicago Auto Show. The possible crown jewel of these cars is the 1971 Plymouth Road Runner, and that's simply because the car is completely unrestored with just 1,300 miles on the odometer. Apparently the owner of the shop that built the car for Chrysler got it back after the Rapid Transit System tour ended and took care of it until he later sold it to the late Steven Juliano, whose estate is now selling this collection of cars. Like all of these cars, modifications were mainly visual, but they were extensive. A custom nose and headlight lenses were fitted that added six inches of length, according to Mecum. The car's bumpers were removed completely, as were the external door handles. Recessed hood scoops were added to the hood, and the trunk lid was lowered by four inches to create a rear wing. The taillights were given red, yellow and green lenses like traffic lights. But the best additions were molded Road Runner head marker lights. The interior is mostly unchanged, and the engine is a stock 383-cubic-inch V8 with an automatic transmission. It also has power steering and brakes and the Plymouth Road Runner horn, which makes a "Beep! Beep!" sound like the cartoon the car is named after. 1970 Plymouth Duster View 12 Photos Then there's the 1970 Plymouth Duster in the collection with arguably the best paint scheme. It's bright green with groovy "DUSTER" lettering on the hood and various contrasting panels. It's actually the second scheme the car used, as according to Mecum, the car was built for the 1970 tour and then redesigned for the 1971 tour. The paint is matched with color-coordinated wheels and blue and green floral pattern floor mats. There are unique body changes, too, such as the custom headlight housings, functional brake air ducts up front, fake extractor vents above the rear window, racing-style fuel cap and rectangular exhaust. Mechanically, it has a stock 275-horsepower 340-cubic inch V8 and four-speed manual transmission.

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."
