Porsche 911 S

The vehicle in detail

The bodywork for the 911 was redesigned from the beltline down, keeping the familiar 911 silhouette. The most dramatic change was the large aluminum impact bumpers with collapsable rubber bellows and shock absorbers integrated into the redesigned fenders and hood. In late 1975, Porsche addressed the issue of corrosion by galvanizing the body panels on both sides. Not only did the galvanizing process ensure longevity, but it also preserved the overall rigidity and crash safety characteristics of the body.

The 2.7 liter 911S engine received Continuous Injection System (CIS) in place of the mechanical injection of previous years as well as a new, quieter exhaust system and an air pump to heat the exhaust gases for reduced emissions. By the 1977 model year, all engines complied with the California emissions standard. The engine fan was revised to be quieter while the engine was in operation by reducing the number of vanes from 11 to 5. All models in the G-platform lineup received larger fuel tanks and batteries, along with a space-saver spare tire beneath the front hood. In the cabin, defroster and center air vents were added along with an electronic blower for the heating system. An electronic speedometer sensor allowed for the addition of cruise control.
