Originally introduced in 1978, the RUF SCR is back this year with a timeless 911-shaped carbon fiber body shell. Yes, that's not a Porsche under there. The carbon fiber body shell is wrapped around a carbon fiber monocoque chassis with an integrated roll cage that's built in-house at RUF. And just like the original, the new SCR is all about power. A naturally-aspirated 4.0L six-cylinder boxer engine and push-rod suspension on both axles help to maximize the SCR's performance potential. Paired with a six-speed manual, the engine produces 510-hp and can hit a top speed of 198 mph.
