In 1982 at the Paris Salon Ferrari replaced the 308 GTBi with the 308 GTB Quattrovalvole. The car remained into production until 1985, with 748 examples produced, in both right and left hand drive versions. Alsoo, all US market examples were fitted with catalytic convertors.
The Quattrovalvole part of the model name referred to the four valves per cylinder heads on the engine, which provided increased power over the preceding model.
The Ferrari 308 GTB Quattrovalvole was very similar to the outgoing one, but could be recognised by the addition of a slim louvre panel in the front lid to aid radiator exhaust air exit, paired electrically operated door mirrors with a small enamel Ferrari badge on the shell, a revised radiator grille with rectangular driving lights at the extremities, and rectangular (instead of round) side repeater lights.
The car received a few minor changes on the interior also: cloth seat centres became available as an option to the standard full leather, whilst the leather rim satin black three spoke steering wheel featured a triangulated section around the horn push.
The options list included: metallic paint, a deep front spoiler, air conditioning, wider wheels, 16" Speedline wheels with Pirelli P7 tyres, and a rear of roof satin black finished aerofoil.
Under the hood Ferrari placed a V8 engine, in 90 degree configuration, with belt driven twin overhead camshafts per bank, having a total capacity of 2926cc. The engine developed a total of 240bhp at 7000rpm for the European models, and 235bhp at 6800rpm for US market variants. It was mated to a transversely mounted in unit with the all synchromesh five speed transmission assembly, which was below, and to the rear of the engine’s sump.
The 308 GTB Quattrovalvole could hit a top speed of 158 mph.
