To ensure that the FIA motorsport governing body would homologate its new 3-litre RSR race car for the 1974 season, Porsche developed the road-going 911 Carrera RS 3.0. Shortly after completing some 1,580 examples of the fabled RS 2.7, the Stuttgart factory produced just 55 units of its brawnier successor. Not only were they far scarcer, and over twice the price, but the model was a true homologation special brimmed with technology developed directly for the track. The engine was a detuned RSR motor featuring a Silumin crankcase, single-plug ignition, and a road-legal exhaust system. Meanwhile, the four-piston callipers and drilled discs were lifted directly from the all-conquering, 24 Hours of Le Mans-winning 917 sportscar. The prominent new front air dam helped keep brake temperatures under control while also feeding the oil cooler for the flat-six, which was rated at 230 horsepower. Helping achieve a remarkable weight of only 900 kilograms, the Carrera RS 3.0 was fitted with lightened glass, had all sound deadening removed, and used composite bonnet and engine cover panels. Given the clear link to Porsche’s thoroughbred racers, the example offered here appropriately boasts competition pedigree. Finished in Grand Prix White, this Carrera RS 3.0 was sold new in Stuttgart on 10 January 1974 and supplied to Mr Byker of Düsseldorf. The following year, it was acquired by keen Italian clubman racer Antonino Guagliardo. In July 1975, having found a faster replacement for his Lancia Fulvia and 911 S, Mr Guagliardo fielded the car in the Targa Florio. Entered by Cefalù Corse with second driver Libero Marchiolo, it was resplendent in its Grand Prix White but featured red bumpers. Unfortunately, the Porsche failed to finish. While Mr Guagliardo eventually switched to forced induction in the form of a Porsche 930, he retained the Carrera RS 3.0 for three decades. The car was then sold to France before, in 2014, it was acquired by a Belgian Porsche dealer. It joined The Stuttgart Legends Collection in January 2015. Presented in its factory colour and wearing dished wheels, a Carrera stripe, and Porsche script all finished in gold, this Carrera RS 3.0 benefits from a February 2025 inspection by marque expert Andy Prill (available to view on file). He noted the original chassis stamping and production number, plus several other authentic 3.0 RS features such as the chassis reinforcements and double-skin rear crossmember. While the current engine has been built around a magnesium crankcase, this car is supplied with its matching-numbers original Silumin crankcase. Please note that this Porsche will require mechanical recommissioning prior to driving following a period of static display. Among the most scarce and sought-after of all road-going 911s, this Carrera RS 3.0 boasts period competition history in the Targa Florio and known ownership from new. The opportunity to acquire such a revered homologation special is not to be missed.
