In the 1970 Porsche 911′s engine capacity was increased from 2.0 to 2.2 litres. The new 2.2-litre engine was used in all versions of the 911. With a bigger displacement, the engine produced more power and better top performance, but the torque gain also improved driveability at lower speeds. The 911 T delivered 125 horsepower, 911 E 155 hp and the 911 S 180 hp. Porsche 911 E and S had a five-speed gearbox fitted as standard and it was available as an optional extra for the T model. Even the 911 T with a four-speed gearbox could reach 205 km/h, while the 911 S with the five-speed had a top speed of 230 km/h.
911 T now had internally ventilated disc brakes and Zenith or Weber carburettors while multi-point injection was standard for the higher-end versions. The two multi-function stalk switches on the steering column for washer/wiper and indicator/headlight functions were a practical detail. The Porsche designers hadn’t just considered increased performance, they also made the vehicle particularly light to handle.
The 1971 models, known internally as the D-series, were introduced with only minor modifications. To comply with new exhaust laws in some European countries the engineers at Porsche had to modify some parts of the fuel injection system. Otherwise the 911 stayed the same. The 2.2-litre engine had only a short history, as it was replaced by a new 2.4-litre engine already in 1972.
