Lamborghini’s third major Countach revision came in March of 1985 at the Geneva Motor Show. The model was named after its new cylinder head which featured four valved per cylinder and it was known either as the Quattrovalvole or QV.
Unfortunately, the QV was a different beast in America and Europe. Emissions and safety regulations meant that the American-spec cars got a hideous rubber bumpers that spoiled Marcello Gandini’s original Countach lines more than anything else. Furthermore, the engine used a Bosch K-Jetronic Fuel Injection that sapped around 35 bhp from the standard Weber setup.
The European QV was much more inline with the stepwise evolution of the Countach. The rocker panels incorporated new staked ducts for the rear brakes and the engine cover was new with a buldge to clear the Weber carburetors.
