The Geneva Salon of 1971 saw the unveiling of the Lamborghini Countach, sanctioned by Nuccio Bertone , and launched to an extraordinary world. Early production cars were the LP400 from 1974 with 3929cc V12 engine, and this had been given large air scoops to cure cooling difficulties not forseen on the show car. In 1978 the LP400 S was launched, acquiring wider tyres and added on wheel arches, plus an optional rear wing. In 1982 the LP500S was produced, changed mainly by getting the larger 4754cc V12 engine. A 5167cc quattrovalvole engine was given to the Countach 5000QV in 1985, and finally in 1988 the 25th Anniversary model was announced with many styling changes. Production ceased in 1990 when the Lamborghini Diablo replace the Countach.
