MERCEDES BENZ SLC

No one really knows what's underneath the elongated aluminum hood but speculation reveals that a turbocharged version of AMG's 6.3-liter V8 might be it. The cab-backwards stance, short rear overhangs and makeshift spoiler all hint at the Merc's pavement punishing potential, and the raised driver's side door -- still far from complete -- appears to remain true to the original 300SL.
