The CTR2, based on the Type 993 Porsche 911 Turbo, featured a 3.6-litre engine tuned by Ruf to deliver 520bhp and 505ft/lb of torque, with later versions reaching 580 horsepower. With a top speed of 217mph, the CTR2 continued the legacy as the world’s fastest production car at its debut. It was available in both two-wheel and four-wheel drive versions.

Ruf also enhanced the car with a custom suspension system, larger brakes, Kevlar body panels, lightweight glass, an integral roll cage, a redesigned rear wing, and Recaro racing seats with Simpson five-point harnesses.

The car featured here is one of two special wide-body CTR2 Sport prototypes entered in the 1997 Pikes Peak International Hill Climb. Built to comply with FIA and Pikes Peak regulations, these 702bhp machines were street legal, unlike most competitors.

The engine’s linear torque curve peaked at 5,000rpm, ideal for the hill climb’s demands. Features include a multifunction rear spoiler for increased downforce and airflow to the intercoolers, a high-mounted main rear wing, Ruf six-speed manual transmission, lightweight carbon fiber doors, and a 100-liter fuel cell.
