2015 Dodge Challenger Drag Pak previewed

Dodge and Mopar have never strayed far from success in drag racing, be it on run-what-you-brung nights at the local strip or at the highest levels of the sport. Hoping to both add to that heritage and capitalize on some of the media spotlight that's shown so brightly on the brand of late, Dodge has given us our first look at the 2015 Mopar Challenger Drag Pak test car.
Though this first iteration doesn't make use of the 707-horsepower Hellcat engine, it seems to be a pretty formidable racing package. Starting with a stock '15 Challenger, Mopar adds a full roll cage built to National Hot Rod Association specs. Rubber front and back is drag racing-ready as well, with 28x4.5-inch tires in the front, and fat 30x9-inch tires out back - all from Hoosier.
Powering the beast is a massive 426-cubic-inch (7.0-liter) Hemi Race V8, with output levels that are still unspecified. A Chrysler 727 automatic transmission connects up to a racing style shift lever, with integral line lock.

One of the prime complaints against the Dodge Challenger is that, even in SRT8 guise, its 470 horsepower is responsible for hauling over 4,200 pounds of vehicle. For comparison, the 420 hp in the Ford Mustang GT only has to deal with 3,618 lbs. Things only get worse from there, as the higher-performance variants of both the Mustang and the Chevrolet Camaro are far more powerful than an SRT8 without adding on much heft.
So what is Chrysler to do? The correct answer is add a whole lot more grunt to its hefty two-door and even the odds. That's where the all-new Hellcat engine comes into play. We reported on this engine in May, and suggested that the Hellcat, a supercharged powerplant based on a 6.4-liter V8, would easily generate 500 to 570 hp and could likely arrive boasting more than 600 ponies.
Chrysler's ace in its sleeve has now been spied testing, with a number of Hellcat-equipped Challengers running the potent new engine both in more urbanized areas and under the sun of Death Valley. The hoods on these testers have been raised to accommodate the engine, and that camouflage over the fascias of these prototypes is there to hide a larger air intake. We also note what appears to be a new split grille under wraps. As for power output, our spies are now suggesting a Viper-equalling 640 hp from the Hellcat-equipped cars.

The horsepower wars are tightening among the Detroit Three, as the Ford Mustang, Chevrolet Camaro and Dodge Challenger are getting bigger, more powerful, and yes, more fuel efficient.
That came into sharper focus this week as more information was revealed about the most insane Challenger ever - the 707-horsepower Hellcat - followed quickly by Ford's in-depth showcase of the 2015 Mustang in Dearborn.
It's shaping up to be a golden age for enthusiasts, and what's under the hood is becoming more important than ever.
