The Carrera RS is a lightweight variant of the Carrera. It features a naturally aspirated 3.8 liter engine generating a maximum power output of 300 PS (221 kW; 296 hp). The exterior is easily distinguishable from a normal Carrera by a large fixed rear wing, small front flaps and 3-piece 18 in (457 mm) aluminum wheels. The headlight washers were deleted for weight saving reasons. On the interior, the rear seats were removed, and special racing seats along with spartan door cards were installed. Sound proofing was also reduced to a minimum. The Carrera RS Clubsport (also referred to as the RSR or RSCS in some countries) was a track-oriented iteration of the Carrera RS with relatively limited road usability. The Clubsport came equipped with a welded roll cage. Certain comfort features such as carpets, power windows , air conditioning and radio were deleted. Exterior wise, it sports a larger rear wing and a deeper chin spoiler than the standard RS. The Carrera RS was produced in model years 1995 and 1996. It was street legal in European and many other countries around the world, but was not approved for export to the United States.
