Lamborghini Countach LP 400S

The 25th Anniversary Edition was the most popular, most refined, and possibly the fastest Lamborghini Countach: 0–60 miles per hour (0–97 km/h) in 4.7 seconds and 183 miles per hour (295 km/h) all out.
• Walter Wolf Countach
In 1975, Walter Wolf, a wealthy Canadian businessman and owner of the Wolf F1 Racing team in the 1970s, purchased an LP 400; however, he was not satisfied with the LP 400's engine and asked Gianpaolo Dallara, the chief engineer of Lamborghini at that time, to create a special high-power version of the Countach. It was the "code No. 1120148" Walter Wolf special with an engine identical to the 5.0 litres (1.1 imp gal; 1.3 US gal) engine from the Countach LP500 prototype, which produced 447 horsepower (333 kW) at 7900 rpm and reached a supposed maximum speed of 315 or 323.6 km/h (195.7 or 201.1 mph). This model also featured the upgraded wheels, Pirelli P7 tires, large fender flares, and front and rear spoilers of the LP 400S model. It was painted red with black fender flares, and was designated "LP 500S" like the standard Countach model from the 1980s, and was the stepping stone that led to this later production model. Two other Wolf Countaches were produced, one painted blue, No. 1120202 (currently in Germany) and one navy blue, No. 1121210. (This machine was owned by Wolf for a long time, but was eventually sold.) Both of the later Wolf Countaches used the original 5.0 litres (1.1 imp gal; 1.3 US gal) engine commissioned by Wolf, transplanted to each car in turn.
