As the name may suggest the amount of muscle in a muscle car is an important characteristic. This week Dodge announced the door slamming 707bhp 2015 Challenger SRT Hellcat just to remind us what muscle really is. Then there is the sound, the Challengers HEMI always sounded good but the Hellcat is a whole other level, its evil good.

The Hellcat features the first HEMI to use a factory installed supercharger which sits atop the 6.2 litre V8, together they produces an incredible 707 brake horsepower and 650 foot pounds of torque. There are two gearboxes to choose from, the Tremec TR6060 six speed manual or eight speed TorqueFlight auto.

Presented for your viewing pleasure are the videos that have captured the amazing growl of the Hellcat. Sit back relax and prepare for the rumble that will make you grin ear to ear.
