Porsche 911 3.0 RS (1974)

Built to homologate the 3.0-litre RSR for the 1974 season, Porsche’s 911 Carrera 3.0 RS wonderfully toed the line between street-legal and competition-bred 911s. Considered by many to be one of the most collectable and desirable 911s ever produced, only fifty-six 3.0 RS’ were built, a minuscule number in comparison to the 1,580 Carrera RS 2.7s that left Stuttgart in 1973.

Updates on these cars were numerous and included not only increasing displacement to 3.0-litres in its type 911/77 engine, but also new cylinder heads with larger inlet ports, revised valve heads with larger inlets and exhausts and a more durable aluminium crankcase. All four wheels were widened by an inch and ventilated disc brakes developed from the 917 helped rein in its performance. As a result of the wider wheels, the bodywork was also widened alongside the fitment of a deeper front bumper to house a larger oil cooler, and the 2.7 RS’ iconic ducktail spoiler was replaced with a larger ‘whale tail’ rear spoiler.
