Xcar Films is taking an even deeper look into the FourSixteen's creation in its latest video with interviews with Saleen and other principles of the tuned Tesla's creation. According to Steve in the video, the company's focus is still on tuning pony cars and building supercars, but "electric vehicles are here to stay."
While Saleen leaves the Model S electric motor and batteries alone, it touches nearly every other part of the Tesla. The FourSixteen feature a new final-drive ratio and tweaked suspension, plus lighter wheels and carbon ceramic brakes to shed quite a few pounds. Of course, the most obvious change is its contentious body kit, especially at the rear, but Saleen claims that it's completely functional by channeling air more efficiently around the car. Like it or not, the FourSixteen might be the future of auto tuning.
