Tesla's Model S P85 can vault from zero to 60 MPH in 4.2 seconds or so -- pretty good for a luxury car with no pistons. Tuning outfit Saleen thought it could top that, though, and has come up with a new version called the Foursixteen. The company also bestows 700HP to Mustangs, but it thinks the Model S "is an entirely new class" of American car equally deserving of such treatment. To that end, Saleen started with the P85 performance variant of the Model S with 416 horsepower and 443 foot-pounds of torque, and changed the final drive ratio for better acceleration. It also added aerodynamic updates, a new suspension, 22-inch wheels, carbon ceramic brakes, a "supercar" interior and a new rear spoiler. The result? A quicker, slicker Tesla Model S that we're guessing won't hit the original EPA range of 265 miles. Oh, and the price: $152,000 instead of around $94,570. Despite its hot-rod status, though, the Foursixteen qualifies for all Federal and state EV rebates -- meaning that depending on where you live, it could be up to $15,000 lower.
