Dodge Challenger spied exercising supercharged Hellcat Hemi V8

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.

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.

Will Dodge limit 2015 Challenger SRT Hellcat to 1,200 units?

With over 700 horsepower on tap and a price tag barely over $60k, Dodge appears on paper to have a winner on its hands with the new Challenger SRT Hellcat. But if you want to get your hands on one, you may have to act quicker than this most powerful of muscle cars covers the quarter-mile.
That's because, according to our compatriots over at Edmunds, Dodge may limit production - in the first year, at least - to just 1,200 units. That would amount to barely a quarter of the Challengers that Dodge moves each month, and would also mean only one Hellcat for every two Dodge dealers in the US - which could lead to some serious contention over which stores and which customers can get their hands on the ultimate Challenger.
Reached for comment, SRT spokesman Dan Reid told Autoblog that "there is no plan to limit production of the Challenger Hellcat," echoing the words of Dodge CEO Tim Kuniskis who told Edmunds: "We don't know what the market demand is." Which doesn't mean that it won't restrict production, but doesn't mean that it will, either. It just hasn't decided yet - or announced any such decision, at any rate - over what will be the final allocation strategy for what could be a game-changing muscle car. That is, at least, until new versions of the Mustang and Camaro come along in pursuit of Dodge's bragging rights...
