Lamborghini Countach LP5000 Quattrovalvole

Introduced in 1985, the Lamborghini Countach LP5000 Quattrovalvole (QV) was the definitive evolution of the iconic supercar. The QV's name comes from the new 4-valve cylinder heads fitted to its 5.2L V12, boosting output to 455 hp in European-spec carbureted form. To accommodate the six massive downdraft Weber carburetors, the engine cover was given a distinctive power bulge, creating an even more aggressive profile than its LP500 S predecessor. For the US market, Bosch K-Jetronic fuel injection was used to meet emissions regulations, resulting in a slightly lower output of 420 hp.

Collectors prize the QV as the ultimate carbureted Countach, offering the most power combined with the raw, unfiltered driving experience the model is known for. It represents the final stage of development before the 25th Anniversary model, which featured significant stylistic revisions by Horacio Pagani and is often seen as a step toward the more civilized Diablo. The QV retains the pure, dramatic lines penned by Marcello Gandini while offering peak performance for the era. Its status as an 80s icon makes it a cornerstone for any serious supercar collection.
