1993 Porsche 911 Carrera RSR 3.8-Litre ‘Strassenversion’ Coupé
The RSR, designed for privateers to compete in international GT racing, marked a significant evolution of the Porsche 911 Type 964. Introduced in 1989, the Type 964 represented a major advancement in the Porsche sports car lineage. It offered two versions, the Carrera 4 and Carrera 2, with the former featuring four-wheel drive for the first time in a series-production model.
Lessons learned from the 959 supercar influenced the new Carreras’ chassis and suspension. Both versions shared a 3.6-liter flat-six engine, with standard features such as power-assisted steering (a first for the 911), anti-lock brakes, and a five-speed manual transmission, while the Tiptronic automatic gearbox was an option for the Carrera 2.
In 1992, Porsche harkened back to the legendary 2.7 and 3.0-liter RS and RSR ‘homologation specials’ of the 1970s with the Type 964 Carrera RS. This lightweight variant, based on the ‘Carrera Cup’ competition model, was exclusively available in Europe and featured a 3.6-liter engine with 260bhp.
The subsequent Carrera RS ‘3.8’ in 1993 increased the bore size to 3,746cc, producing 300bhp. This M64/04 engine was installed in a wider, Turbo-style body, also used for the more powerful and lighter RSR competition version, estimated to have between 325 and 350hp. Approximately 50 of these 3.8-liter RSRs were produced when the Type 964 production concluded in December 1993, with only two being street-legal versions.
