The mid-1970s was a tough time for Porsche. The 914 stopped production, and the 911 was going through a slump, with little relief on the horizon but for the front engine, VW-produced 924, which ended up being a great car but that many still resented it being called a Porsche. What the German manufacturer needed was a hit, something to stir passions, and with the 1975 Porsche 911 Carrera RS 2.7, it found it. Still regarded today as one of the greatest sports cars ever produced, the Carrera RS 2.7 represented everything that’s awesome about the 911, multiplied ten-fold. The weight was reduced by over 325 pounds, and a duck-tail spoiler was added, which greatly improved stability at high speed, and metal bumpers were replaced with integral plastic ones for a sleek, modern look.
What really changed, however, was the engine. Displacement was boosted to 2.7 liters by over-boring it by 6mm, to 90mm; a new coating process was used inside the cylinders to reduce friction (Nikasil coating), and Bosch fuel-injection was added, bringing the power available to this little supercar to 210 horsepower. Needless to say, performance followed: top speed of 149 miles per hour, and 0-60 acceleration in 5.7 seconds.
Very rare today, the Carrera RS gave the 911 the boost it needed, and proved very popular indeed. Another version of the 1975 Porsche 911 Carrera RS 2.7, called the RS Touring was also produced, minus the rear spoiler, for a more discreet look.
