In a surprise move, the company was bought by the Chrysler Corporation in 1987 with the acquisition being driven by Lee Iacocca, Chrysler's chairman at the time. Lamborghini was then working on the Countach's successor, the Diablo. The basic design of the Diablo was by Marcello Gandini, who designed the Miura and the Countach while at Bertone. The design was further developed by Chrysler, which brought its resources, including design input, pollution controls, and new manufacturing techniques, into this development. Chrysler's experience with the design of mass market vehicles improved areas of practicality and comfort that had been neglected earlier, including noise, vibration, and harshness (NVH), engineering, and ergonomics..
Post-Chrysler: Megatech and Audi
In 1971, Lamborghini produced the LP500 Countach prototype. The Countach was named after an Italian dialect term uttered in surprise by Nuccio Bertone upon seeing the car for the first time. The production LP400 Countach was introduced three years later. The prototype was the first car to sport Lamborghini's now-traditional scissor doors, along with vertically mounted rear air intakes.
The Countach's V12 engine initially had the same 4-litre capacity as the Miura, but this was enlarged to five litres upon the introduction of the LP500S Countach in 1982. The Countach was one of the first cars to use the Pirelli "P-Zero" tires. Lamborghini's test driver would often demonstrate the Countach's abilities to journalists. A detail noted by journalists was the manner in which a Countach was reversed; the driver would raise the door and sit on the door sill.
