Even five years after its final production, the Porsche Carerra GT lives on in the hearts and minds - and often driveways - of Porsche loyalists, supercar enthusiasts and plain old gearheads. And now Porsche is rumored to be working on a successor based around the RS Spyder American Le Mans Series (ALMS) race car.
With 485-503bhp from its 3.4L V8 and just 775kg, the LMP2-class RS Spyder has taken class or overall victories at the 12 Hours of Sebring and 24 Hours of Le Mans, in addition to numerous other races and the 2006-2008 LMP2 ALMS manufacturer's championships.
That kind of track cred is a solid foundation on which to build, but so far we can't confirm any plans to take the RS Spyder to the street. The rumors has a hint that a slight downgrade in power and rise in weight for street-trim will be in order.
If the RS Spyder does go road-legal, it will probably be in the neighborhood of 400bhp (298kW) and 1,000kg - right on par with the outgoing Carerra GT in power-to-weight ratio, but ultimately higher-performing due to its lighter weight. A production engine from Porsche's existing lineup will also likely be sourced to replace the race-spec model.
The carbon fiber tub chassis and running gear are expected to carry over from the race car, though the suspension will be detuned for bumpy city streets and the body and cockpit will be similarly relaxed to allow for more creature comforts. The two-seat roadster layout would be retained, however.
