Kyosho 1:18 Lamborghini Countach, Red: Walter Wolf Racing

In 1975, Walter Wolf, a wealthy Canadian businessman and owner of the Wolf F1 Racing team in the 1970s, purchased an LP400; however, he was not satisfied with the LP400'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 L (310 cu in) engine from the original 1971 LP500 prototype, which generated 333 kW (453 PS; 447 hp) at 7,900 rpm and enabled the car to attain a theoretical maximum speed of 315 or 324 km/h (196 or 201 mph). This model also featured upgraded wheels, Pirelli P7 tyres, flared arches, and front and rear spoilers, all features that would become integrated on future Countach's starting with the LP400 S. Wolf's car was painted red with black flared arches, was designated "LP500 S" like the standard Countach model from the 1980s, and was the key stepping stone that led to the development of these later production models.

Two subsequent Wolf Specials were produced, the first, painted Bugatti blue, No. 1120202 was kept by the factory, and the last, a darker navy blue, No. 1121210 was the very first LP400 S and presented at the 1978 Geneva Motor Show. Both of the later Wolf cars used the original 5.0-litre engine commissioned by Wolf, transplanted to each car in turn.
