Good night! Dodge has finally revealed the talked-about-in-whispers 2015 Challenger SRT Hellcat, and – if you haven’t sat down already, please do so – it chucks out a staggering, unimaginable 707-horsepower. That puts this big daddy at the top of the list: the most powerful muscle car ever, according to Chrysler at least.

But don’t think that Dodge just shoehorned a whopping 6.2-liter supercharged HEMI Hellcat V8 into the Challenger and shipped it out the door. No, no. To handle its monstrous horsepower and 650 lb-ft of torque, the Hellcat shuttles power to the rear wheels through a heavily upgraded TorqueFlite eight-speed automatic gearbox. We’ll have to get back to you on 0-60mph times, but expect them to be…uh…fast.

To complete the track-terrorizing package, Dodge provides drivers with two keys – one red and one black. The red key unlocks the full 707hp potential of the car, while the black key limits output to a still-very-significant 500hp.
