Porsche 911 S 2.4 Coupe 1972Following the stricter emission regulations in 1971, Porsche was forced to make changes to 911’s engine. However, Porsche was not willing to make any concessions in terms of engine power.

Only possible way to achieve smaller emissions and still deliver the same performanc as before, was to increase the engine displacement. Porsche decided not not to increase engine bore, but rather piston stroke. The result was the Porsche 911 2.4.

The Porsche 911 2.4 was available in three versions. The power output of the Porsche 911 T, E and S models were increased, to 130, 165 and 190 bhp. All engines were able to run on regular fuel. By increasing the engine capacity to 2341 cc and decreasing the compression, even the Porsche 911 2.4 S was able to run on regular fuel and still deliver the engine output of 190 bhp at 6500 rpm.

Porsche 911 2.4 was available as a Coupe and Targa models. Porsche introduced the Targa model in response to increased safety requirements for open-top vehicles in the USA. Thanks to the fixed bar, the occupants were protected from injury in the event of the vehicle overturning.
