COUNTACH LP 400
Because of fast changes in tire-technology, the faults of the Miura chassis showed up, so it was time for something new, that was not easy, it had to be faster, better and more outrages than the Miura. Paolo Stanzini and his team started from scratch, and designed a completely new car. Their ideas were based on the use of the new Pirelli tyres who promised incredible cornering speeds. The engine and gearbox design was completely different, the gearbox was in front of the engine and the drive shaft went right through the oil pan. This construction was heavier and the center of gravity was higher, but it had the advantage of more weight on the front-wheels, which was an improvement in road holding, and the gear change was almost in place so gear change was much better then in the Miura. The Miura engine was changed to 4971 cc. and delivered 440 Hp. at 7400 Rpm. The chassis was a space-frame of steel tubes, and Bertone's Marcello Gandini styled the car. As the Countach LP 500 prototype it first appeared on the 1971 Geneva Motor show. Everybody was completely outrages about the car, but it was far from production, the 5 liter engine was blown, and further testing was performed with the standard 3,9 Ltr. engine. Like the Miura, the car had cooling problems, and many more things had to be sorted out. The second prototype, this time called LP 400 appeared in Geneva in 1972, and was a red car, the third (a green one) was shown in 1973 in Paris. The first real production LP 400 was introduced in 1974 in Geneve, at that moment Ferruccio Lamborghini had sold his company to two Swiss man : Rosetti and Leimer, the future for the Lamborghini concern wasn't bright.(not as bright as the yellow LP 400)

COUNTACH LP 400 S
In 1978 the Pirelli P7 tyres came available, the Countach was originally designed for this tyre but they were not available when the first Countach was produced, and the new S version was the first to use them, they appeared on the famous telephone-dial wheels. An all new parallel arm rear suspension was mounted, the roof line was raised to give more headroom, and the periscope mirror from the first model disappears. The wider wheels, the flaired wheel arches and the new skirts gave the car an even more aggressive look then the normal LP 400

COUNTACH LP 5000 S
The real name for this model is LP 500 S, however the cars were badged 5000, why ?, nobody knows. The car was fitted with a bigger engine ( as was the original plan), and had electronic ignition to meet the american emission standards, this was why the bigger engine didn't deliver more power than the engine's from the 400 (s). The pick-up points for the front-suspension were changed again to induce mild over steer, and the dashboard was renewed. Rims were now from Oz racing.

COUNTACH LP 5000 S QV
Again this model was badged 5000. 14 years after the introduction of the LP 500 model the original specs were available (even a little more) due to the new 4 valve per cilinder head = QV = Quatro valve. The engine was enlarged, and due to its QV head it could meet the emission demands while delivering 455 Hp. A large rear wing was introduced as an option, it looked great, but added only weight to the car, with wider skirts and the wing the car was even more outrages then all his predecessors.

COUNTACH 25 ANNIVERSARY
To celebrate the 25 th anniversary this model was introduced, it is the most spectacularly of all, the body was heavily revised with very wide skirts, NACA ducts, big air intakes at the rear and boxed arches to support the new rims with Pirelli P Zero tyres. Due to the new tyres the suspension was changed again. This was the last Countach.... the work on his big brother was started: the Diablo.
