The Lamborghini Countach is a rear mid-engine, rear-wheel-drive sports car produced by the Italian automobile manufacturer Lamborghini from 1974 to 1990. It is one of the many exotic designs developed by Italian design house Bertone, which pioneered and popularized the sharply angled “Italian Wedge” shape.

The style was introduced to the public in 1970 as the Lancia Stratos Zero concept car. The first showing of the Countach prototype was at the 1971 Geneva Motor Show, as the Lamborghini LP500 concept.

The “Countach” nameplate was reused for the Sián-based limited-production hybrid-electric model called the Countach LPI 800-4 in 2021.

The first production cars used a 3.9-litre engine as durability issues with the new 5-litre engine could not be resolved in time. As equipped to the 1974 Countach LP400, the engine was rated at 276 kW (375 PS; 370 hp) at 8,000 rpm.

The stated power output was less than that of the Miura SV, which was blamed on the use of side-draft Weber 45 DCOE carburetors instead of the down-draft carburetors used on the Miura.

Later engine development eventually increased the engine displacement to 4,754 cc (4.8 L) in the 1982 LP500S, and then to 5,167 cc (5.2 L) with four valves per cylinder in the 1985 LP5000 Quattrovalvole.

All variants of the Countach were equipped with six Weber carburetors until the arrival of the LP5000 QV model, some of which used Bosch K-Jetronic fuel injection to meet US emissions regulations. European-specification cars continued to use carburetors until the arrival of the succeeding Diablo.
