The 911 – The 2.2 Liter Cars

2.2-litre / C and D series (1969–1971)
For MY 1970 the engines of all 911s were increased to 2,195 cc (2.195 L; 133.9 cu in). Power outputs were uprated to 125 PS (92 kW; 123 hp) in the 911T, 155 PS (114 kW; 153 hp) in the 911E, and 180 PS (130 kW; 180 hp) in the 911S.

The 912 was discontinued, thanks to the introduction of the Porsche 911T as an entry model.

The 2.2 L 911E was often called “The secret weapon from Zuffenhausen”. Despite the lower power output of the 911E compared to the 911S, the 911E was quicker in acceleration up to 160 km/h (99 mph).
