1979 RUF 3.4 CR (based on Porsche 911 SC)
- Engine
- Naturally aspirated 3.4L flat-six with limited-slip differential

A 1979 Porsche 911 SC converted by RUF Automobile at their Pfaffenhausen works in 2014 into a 3.4 CR specification — the naturally aspirated sibling to the turbocharged CTR 'Yellow Bird'. The transformation included Yellow Bird bodywork, RUF wheels, a five-speed RUF gearbox, a 3.4-litre flat-six with limited-slip differential, and a bespoke interior with Porsche 968 Club Sport seats retrimmed in monogrammed jacquard. Documented by the original factory invoice, the car has remained under specialist care in Germany and subsequently the United States.
