For 2018, the Dodge Challenger Hellcat is wider & faster. They call it the Widebody because they fattened up the front end with the addition of the fender flares and lip spoiler used on the Dodge Demon. And by also adding width to the front tires, aerodynamics are improved. The 707-horsepower supercharged V8 is now faster on the straights and grippier in the corners, giving it a 0-60 time of 3.4 and a 10.9 second quarter mile.
