The RCT (abbreviation of "Ruf Carrera Turbo") came into production in 1992.

At the time, the Ruf workshops had spare parts for the Porsche 964, Carrera 2, Carrera 4 and Carrera RS; the dismantling of these models resulted in components for the creation of the Ruf BTR III and BTR 3.8.

To accommodate the turbocharger, several original parts had to be replaced.

It offered performance similar to that of its predecessor, the BTR.

[1] The later model developed a similar design, the RCT EVO.
