The Best of the Best 2003: Aftermarket - Ruf Rturbo
Take a narrow-body Porsche 911, insert heavily modified turbochargers, replace the exhaust and intakes with deeper breathing units, remap the engine management system, graft on more efficient and aerodynamic bodywork, upgrade the suspension, and call it complete. The result? A $200,000 Ruf Rturbo with four-wheel drive and Porsche Stability Management (PSM). This is a Porsche 911 that develops 550 hp, sprints from zero to 60 in 3.7 seconds, and tops out at 218.5 mph.
