It will be hard to spot the difference between the new and the old as the images reveal. This is because most of the planned changes will be taking place under the sheet-metal.
Power levels should receive a slight boost over the 405hp (302kW) output courtesy of a new direct-injection system. In line with the changes in the facelifted Carrera range, the engine in the updated GT3 RS will also sport bigger combustion chambers, a new crankshaft and an upgraded oil and water pump.
The GT3 RS will also once again based on the Carrera 4 body and should feature the same widened track, carbon-fiber interior and plastic rear window as the current model.
