Two years later, at the 1982 Paris Motor Show, Ferrari launched the 308 quattrovalvole, in GTB and GTS form. The main change from the 308 GTBi/GTSi it succeeded were the four valves per cylinder—hence its name, quattrovalvole, literally "four valves" in Italian—which pushed output back up to 240 hp (179 kW) restoring some of the performance lost to the emission control equipment. The new model could be recognized by the addition of a slim louvred panel in the front lid to aid radiator exhaust air exit, power operated mirrors carrying a small enamel Ferrari badge, a redesigned radiator grille with rectangular driving lights on each side, and rectangular (in place of round) side repeaters. The interior also received some minor updates, such as a satin black three spoke steering wheel with triangular centre; cloth seat centres became available as an option to the standard full leather. Available options included metallic paint, a deep front spoiler, air conditioning, wider wheels, 16-inch Speedline wheels with Pirelli P7 tyres, and a satin black roof aerofoil (standard on Japanese market models). Apart from the DOHC 32-valve cylinder heads, the V8 engine was essentially of the same design as that used in the 308 GTSi model. Total displacement was 2,927 cc ( L; cu in), with a bore x stroke of 81 mm × 71 mm ( in × in). Output on European specification cars was 240 PS (237 bhp; 177 kW) at 7000 rpm and 260 N⋅m (192 lb⋅ft) at 5000 rpm of torque, while for US specification variants were 233 PS (230 bhp; 171 kW) at 6800 rpm and 255 N⋅m (188 lb⋅ft) at 5500 rpm of gear and final drive ratios were altered to suit the revised characteristics of the 4 multivalves per cylinder engine. One other significant benefit of the QV four valve heads was the replacement of the non-QV models sodium valves which have been known to fail at the joint between the head and the stem.
