Exclusive: Porsche 991 GT3 RS spy shots

The Porsche 991 GT3 RS has been spotted testing at the Nürburgring Nordschleife and Total 911 can bring you exclusive spy shots of the latest 911 to carry the iconic Rennsport moniker.

The 991 GT3 RS will use the 991 Turbo’s wide body, as does the 991 RSR raced by Porsche in the FIA WEC and TUSCC. This makes it 28mm wider than the 991 GT3, a car that uses the slightly less-wide Carrera 4 shell.

This test mule keeps the Turbo’s rear arch air intakes however, the 991 GT3 RS will continue to be naturally aspirated, using the 991 GT3’s 3.8-litre engine, with a power output rumoured to be around 500bhp.

If the air intakes remain on the production model, it is likely they would be used to cool 991 GT3 RS’s rear brakes, in the same fashion as the original arch vents found on the 964 Turbo models.

Aerodynamically, the Porsche 991 GT3 RS will be the closest to a racing car Porsche has ever gone with a production model. The rear wing looks to be straight from the latest GT3 Cup racer, with the dive planes on the front bumper mirroring those used on the 997 GT3 RS 4.0.

There appears to be a lot of camouflage tape stuck centrally along the 991 GT3 RS’s roof. This could be to hide a roof-mounted cooling duct however, this would be unusual, especially for a road car. As a comparison, the 991 RSR takes its cockpit ducting from the front of the car.

The Porsche 991 GT3 RS is likely to retain the GT3’s PDK-only transmission, though the possibility of even faster shifts from the dual-clutch gearbox cannot be ruled out.

From these spy shots, the latest 911 GT3 RS appears to sit lower than its ‘warm’ 991 GT3 brother and, to make this into the ultimate track weapon, its likely new spring rates and damper settings will be utilised in order to work with the increased aerodynamic grip.

Rumour has it, the 991 GT3 RS is scheduled for a 2014 launch so Total 911 wouldn’t be surprised to hear an announcement around the back end of this year, possibly in time for the Paris Motor Show in September. Is this the most eagerly anticipated 991 yet?
