Designed to be the more comfortable and drivable of the 911 range, and fitting in between T (Touring) and the S (Super), the designation ‘E’ came simply from the German for injection. The mechanical fuel injection system (MFI) was used on the 911E and the 911S, and developed jointly between Bosch and Porsche. The benefits were better power and drivability with a cleaner running engine. The interior had a few more comfort features, better brakes and gold script on the engine cover. The 911 2.2 E were called “The secret weapon from Zuffenhausen”. Despite the lower power output compared to the 911 2.2S, the 911E actually accelerated more quickly.
