RUF CTR3 Clubsport
The RUF CTR3 Clubsport represented a fundamental evolution for the Pfaffenhausen-based manufacturer. While RUF had previously modified Porsche-built cars, the CTR3 was built on RUF's own carbon fiber and steel tubular chassis, making it an entirely independent creation that happened to use a Porsche-derived flat-six engine. The Clubsport variant took the standard CTR3's already impressive 700 horsepower and pushed it to 777 hp, while adding track-focused suspension calibration and lightweight components. The mid-engined layout was a departure from Porsche's traditional rear-engine configuration, providing better weight distribution and more predictable handling at the car's extraordinary speed capabilities. The flat-six engine, expanded to 3.8 liters and fitted with larger turbochargers, produced its power with the characteristic flat-six wail that only a horizontally-opposed engine can deliver. Inside, the RUF featured a purposeful but well-appointed cabin with leather, carbon fiber, and RUF's signature green instruments. With only approximately 30 CTR3s built in total, and fewer still in Clubsport specification, this is among the rarest and most capable supercars of the 21st century.
Extreme rarity makes finding one the biggest challenge. Verify provenance through RUF directly. Service should be performed at RUF in Pfaffenhausen or authorized RUF specialists. The flat-six engine, while Porsche-derived, has RUF-specific components. Carbon-ceramic brakes need monitoring.
The CTR3 was built on RUF's own chassis, not a modified Porsche. This makes RUF a manufacturer in its own right, similar to their CTR Anniversary and SCR models. The Clubsport upgrade was available as both a factory option and a retrofit to existing CTR3s. The Ricardo sequential gearbox was a race-derived unit.
