With a view to further improving weight distribution for the Countach, the design team used the same engine but relocated it to mid-rear position and rotated it an additional 90 degrees, basically 180 degrees compared to the first 350 GT. They mounted the gearbox in front of the engine, practically “in the cockpit”. In its final iteration, the Countach’s engine capacity had increased to 5.2 liters. With the model year 1986, the V12 mounted in the Countach was also homologated in the U.S. market. This milestone was achieved using electronic fuel injection, which replaced carburetors in markets where anti-pollution regulations were more stringent.
