On this episode of Head 2 Head, presented by Tire Rack (http://www.tirerack.com), host Jonny Lieberman puts the quickest sedan in the world up against the fastest sedan in the world. Unlike most "this versus that" competitions, the object of this match up is to figure out which family sedan is the bigger badass. In the red corner, making 691 electric horsepower and 687 pound-feet of torque, is the dual-electric motor, all-wheel drive Tesla Model S P85D. And in the blue corner, packing a supercharged 6.2-liter V-8 that’s good for 707 hp and 650 pound-feet of torque. As you can gather from the power figures, these two are evenly matched. But one’s a bigger badass than the other. Watch and find out which!
