In the 911 G-Series, Porsche fitted a turbocharger in the 911 for the first time in 1974. The Turbo would become synonymous with extreme performance, especially once an intercooler was added to the mix in 1977. From 1975, hot-dip galvanised sheet metal for the body and floorpan offered greater durability and resistance to rust. With the 911 Carrera 3.2 for the  1984 model year, Porsche introduced digital engine electronics.
