Porsche 911 Targa
Model year 1974 saw three significant changes. First, the engine size was increased to 2687 cc giving an increase in torque. Second, was the introduction of impact bumpers to conform with low-speed protection requirements of US law, these bumpers being so successfully integrated into the design that they remained unchanged for 15 years. Thirdly, the use of K-Jetronic CIS Bosch fuel injection in two of the three models in the line up— the 911 and 911S models, retaining the narrow rear arches of the old 2.4, now had a 2.7-liter engine producing 150 PS (110 kW; 150 hp) and 175 PS (129 kW; 173 hp), respectively.
