Supercars require a delicate balance blending brute force, a refined suspension and eye-popping design. For the moment, Saleen isn't revealing all the details, but when it comes to power, we're told this bird boasts a 650-horsepower version of Saleen's own 5.0-liter V-8. The supercharged powerplant will launch the S5S Raptor from 0- 60 in well under 4 seconds, we're told.

Expect to see a production version of the Saleen S5S Raptor reappear at the New York Auto Show in about two years.
