Lamborghini Countach 5000 Quattrovalvole Downdraft

Perhaps the most iconic supercar of the last 30 years, the most powerful variant of Lamborghini’s Countach never officially made it to North America. The original was certainly a flamboyant creation when it was introduced in 1974, an instant poster classic which adorned many a teenage bedroom wall. The Bertone-designed supercar grew ever more extravagant as engineers sought various measures aimed at keeping it pinned to the road in response to the ever-increasing power output from its refined V12 powertrain.

Bored-out to 5.2 liters for 1985, the V12 was also given four valves per cylinder, for a total of 48, hence the moniker “Quattrovalvole”. European-specification Countach models gained six Weber downdraft carburetors located on the top of the engine, rather than from the side, while North American models received Bosch's K-Jetronic fuel injection system in order to comply with more stringent emissions laws. About a dozen Quattrovalvole Downdrafts, as they are known, made their way to North America via the then-burgeoning gray market, where original owners quickly paid a hefty premium for the roughly eight percent jump in horsepower to an impressive 455.

This car was auctioned off by RM Auctions in August 2009 at the Portola Hotel & Spa and Monterey Conference Center, Monterey, California.

455 bhp, 5,767 cc four overhead cam alloy block and head solid lifter V12 engine with six Weber downdraft carburetors, five-speed manual transmission, four-wheel independent suspension and four-wheel disc brakes. Wheelbase: 98.4".
