Background
The much-anticipated replacement for the Dino 246 GT and GTS, the Ferrari 308 was introduced in 1975, following the now-familiar mid-engine, v8-powered template that had proven to be - and would continue to be - the basis for almost all iconic Ferraris of the century.
Available in both GTS (from 1977) and GTB formats, the 308 was constructed around a tubular frame, a belt-driven, DOHC V8 engine and a transaxle transmission setup, with a five-speed ‘dog leg’ gearbox and LSD.
Early models (until 1980) were equipped with four twin-choke Weber 40DCNF carburettors and single coil ignition, producing 252bhp for EU-delivered models and a lower 237bhp for US-delivered cars, due to tightening emissions regulations. Post-1980, cars were offered with mechanical fuel injection in the form of the Bosch K-Jetronic system, with these cars being designated the 308 GTBi and GTSi respectively.
The other major feature that separates the really early cars is that the body for the 308 was initially made of GRP, with a kerb weight of only 1,050kg. Post June 1977, however, the bodywork was changed to a conventional steel construction, with an additional 150kg added to the weight as a result.
It should be noted that all GTS models are steel-bodied, and also used a wet sump engine, whilst EU GTB models retained the dry sump setup until 1981.
In total, 3219 GTS’ and 2897 GTBs were made between 1975 and 1980, of which only 808 were GRP-bodied GTBs.
