Images: Porsche C- and D-Series 911 Coupe (1969-71)
Production of the Porsche C-Series 911 Coupe commenced in August 1969 at Porsche’s Zuffenhausen factory in Stuttgart, Germany. Compared to its B-Series predecessor, the C-Series 911 introduced a 2.2-litre horizontally-opposed (or flat) six-cylinder engine which had better low-end power and a broader torque curve.

Produced from August 1971, the Porsche E-Series 911 introduced a 2341 cc engine as its stroke was extended from 66.0 mm to 70.4 mm. Due to air pollution and low-octane fuel requirements, compression ratios were lowered to 7.5:1 for the 911 T, 8.0:1 for the 911 E and 8.5:1 for the 911 S. The Porsche E-Series 911 Coupe was fitted with a new five-speed 915 manual transmission which had a conventional H-I gearshift pattern rather than the racing-style shift pattern of its predecessors. The Porsche E-Series 911 could be identified by its repositioned oil tank which had an oblong hatch behind the passenger door. For the F-Series 911 (produced from August 1972), however, the oil tank was returned to its original position in the engine bay to avoid confusion with the fuel tank.
