Ferrari 308 GTB Quattrovalvole (1983 to 1985)

In late 1982 the Ferrari 308 would evolve yet again into the 308 GTB Quattrovalvole (QV). A GTS Quattrovalvole (spider) was also introduced. The main change from the 308 GTBi and 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 emissions control equipment. In 1985 the Ferrari 328 was launched, which replaced the Quattrovalvole. Between 1982 and 1985 a total of 748 GTB QV examples were produced.
