Lamborghini Countach LP5000 Quattrovalvole

The Lamborghini Countach LP5000 Quattrovalvole, or 5000 QV, appeared in 1985 when the engine was bored and stroked to 5,167 cc and given four valves per cylinder, quattro valvole in Italian. The carburettors moved from the sides to the top of the engine for better cooling, which created a hump on the engine cover that reduced the already poor rear visibility, and some body panels became Kevlar. The fuel injected engine was rated at 313 kW and 461 newton metres, while the European carburettor versions with six Weber carburettors made 335 kW. 610 cars were built to this specification, 66 of them with fuel injection, and a US specification model was produced by the factory.
