This thing is so awesome.
For those who want a muscle car that offers in excess of 700 horsepower but don't want a Dodge, the pickings are mighty slim. And for those who want a really massively powerful version of the current generation, there isn't even a new GT500 yet. But this is what we have Hennessey for, the tuner's HPE700 kit for the 2015 Mustang bumps power up to 717 horsepower and 632 lb-ft of torque. It'll hit 60 mph in 3.6 seconds and run the quarter mile in 11.2 seconds.
And here was have a video of it hitting its top speed of 195 mph. Not bad at all.
