Lamborghini Countach LP400
The Countach entered production as the LP 400 with a 4.0-litre (3929 cc) 375 PS engine. The first production Countach was delivered to an Australian in 1974. Externally, little had altered from the final form of the prototype except at the rear, where conventional lights replaced the futuristic light clusters of the prototype. The styling had become rather more aggressive than Gandini's original conception, with the required large air scoops and vents to keep the car from overheating, but the overall shape was still very sleek. The original LP 400 rode on the quite narrow tires of the time, but their narrowness and the slick styling meant that this version had the lowest drag coefficient of any Countach model and possibly the highest top speed. The emblems at the rear simply read "lamborghini" and "Countach", with no engine displacement or valve arrangement markings as is found on later cars. By the end of 1977 the company had produced 158 Countach LP 400s.
