“Inspired by, and created for, Roger Penske, the 963 RSP is a special, one-off car based on the Porsche 963 racing prototype used in the WEC and IMSA series. It has been modified extensively inside and out by the Sonderwunsch department, with unique bodywork and a bespoke interior – inspired by a Porsche 917 (Chassis 30) which featured very similar changes when it first took to the public roads 50 years ago.

“Like the 917, the 963 RSP features a custom paint finish (in exactly the same Martini Silver color worn by the 917) as well as a bespoke leather and Alcantara interior. Beyond that, adjustments were made to the dampers, ride height and engine control unit to make the car more suitable for driving on the road and even enabling it to run on standard fuel. The car was also fitted with turn signals, wet weather tires and even a horn,” Porsche said.
