Lamborghini Countach LP 400S

Named to honor the company's twenty-fifth anniversary, in 1988, the 25th Anniversary Countach was mechanically very similar to the 5000QV but sported much changed styling. The rear "air boxes" were restyled and enlarged, while the vents behind them were changed so that they ran front to back instead of side to side. In addition, a new air dam and side skirting, both with air intakes, were fitted, and the taillights were restyled to be narrower, with body-colored panels replacing the upper and lower parts of the previous large taillights. The styling changes were unpopular with many, particularly since the intakes had strakes in them that appeared to mimic those on the Ferrari Testarossa, but they improved the engine's cooling, a problem the Countach had always struggled with. It also featured 345/35R15 tires; the widest tires available on a production car at the time. The Anniversary was produced through 1990 when it was replaced by the Lamborghini Diablo.
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.
