A handful of specially prepared lightweight 911s were fabricated by the Porsche factory and called the Carrera 4 RS Lightweight. These employed the same six-cylinder 3600cc boxer engine as the 260hp “regular” RS, but produced some 40 more horsepower due to the exclusion of catalytic converters and mufflers.

The RS Lightweight earned its name thanks to the combined use of an aluminum front lid, aluminum doors, Plexiglas side windows and a fiberglass rear engine lid. Its overall weight was pared down to 1100kg thus making for an exceptional power to weight ratio.

The list of features included an aluminum safety cage, two Recaro race seats with five-point safety belts, sport steering wheel coupled to a power assisted steering rack and a type 953 Paris-Dakar transmission.
