The Porsche 911E continued as the midrange 911 model for 1972 and 1973, fitting between the contemporaneous 2.4L 911T and the 2.4L 911S. As with the T and S variants, Porsche would upgrade the 911E to a new, larger 2,341 cc (2.3 L) engine, commonly known as the "2.4 L" engines. The 911E version, designated 911/52 was rated at 165 hp (it was designated 911/62 with Sportomatic). With the power and torque increase, the 2.4-liter cars also got the newer and stronger transmission.
The Porsche 911E continued as the midrange 911 for the 1970 and 1971 model years, fitting between the contemporaneous 2.2L 911T and the 2.2L 911S. It produced 155 bhp and featured all the upgrades that came with C-Series production including longer wheelbase, Fuchs alloy wheels. Both the E and S model 911 had an aluminium engine-lid and aluminium bumpers. The 911 E 2.2 was once again available as either a Coupe or Targa body. For model year 1972, the 2.2L 911E was replaced by the 2.4L 911E.
The Porsche 911 E was designed to fall nicely between the 911 T touring model and the top of range high-performance 911S. The Porsche 911 T would continue for its second year in Europe, and newly introduced into the United States market, as the entry level offering for the 911, sitting below the 1969 911E and the 1969 911S. The 1969 911E was powered by engine Type 901/09 (Type 901/11 with Sportomatic) featuring mechanical fuel injection (MFI). The 2.0 L Aircooled Flat 6 was good for 140 bhp at 6500 rpm.
