We already know everything about the stock 707 Horsepower Challenger Hellcat.
So what did Hennessey do to this particular 2015 Ford Mustang GT? Oh Not much, except they put their 2015 Hennessey HPE750 package on the car. It even has more horsepower then the beastly Challenger Hellcat – 774 horsepower vs. 707 horsepower – and has been clocked at and incredible 207.9 miles per hour top speed. from a standing start this beast will do do 0 to 60 in 3.4 seconds and cover the quarter-mile in a blistering fast 10.9 seconds with a mind-boggling trap speed of 133 mph.
Hennessey has been working on this Mustang package for quite some time now, and we’ve posted about it on numerous occasions. Essentially, this huge 2.9-liter supercharger kit takes the Coyote 5.0 eight cylinder engine into the supercar performance levels.
