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.

Watch the Dodge Charger SRT Hellcat verify its 204-mph top speed

The industry is producing some ridiculously fast four-doors these days, from the Porsche Panamera and Maserati Quattroporte to the Mercedes E63 AMG and BMW M5. But the fastest of them all doesn't cost six figures. It doesn't even come from Europe. It's made right here in North America, by a US automaker. And it starts at under $64k. We're talking about the Dodge Charger SRT Hellcat, the Pentastar muscle sedan with the 6.2-liter supercharged V8 and its 707 horsepower. Dodge claims it's the "quickest, fastest, most powerful [production] sedan ever," and they're not just blowing smoke... or smoking tires. During the final stages of development, engineers from Auburn Hills took a bone-stock, Hellcat-powered Charger out to a seven-mile oval for a top speed run and they filmed the occasion for posterity. The result? 206.9 miles per hour with the wind, 202.2 against it, for a two-way average top speed of 204.55 mph. Chew on that, imports.

2013 Dodge Challenger R/T Redline revs into Chicago

When Dodge released the Challenger Rallye Redline last year, it brought a new dimension of styling to the car's classic muscle car lines, but it was only available in V6 form lacking the oomph to back up its sinister appearance. To remedy that situation, Dodge is unveiling the Challenger R/T Redline, powered by a Hemi V8 engine, at the Chicago Auto Show.
Other than the extra cylinders, most of the R/T's Redline package carries over from the Rallye model including the custom-look 20-inch black chrome wheels with red paint accents, but the R/T version of the package gets more of a retro look to the side stripes with graphite graphics featuring Redline lettering. Cars equipped with the six-speed manual transmission will get a performance-tuned, low-restriction exhaust allowing the engine to produce 375 horsepower and 410 pound-feet of torque; cars with the five-speed auto are rated at 372 hp and 400 lb-ft, but they do offer a bright chrome Mopar t-handle shifter and steering wheel paddle shifters.
The R/T Redline Group is offered only on cars painted in Billet Silver, Granite Crystal, Bright White and Pitch Black, and it adds just $1,995 to the MSRP of the Challenger R/T (starting at $31,990) and the Challenger R/T Plus (starting at $33,990), which adds features like Nappa leather and Boston Acoustics speakers.
