Spied! Porsche 911 GT3 RS Prototype Caught Cold Weather Testing

A prototype for the 991-generation Porsche 911 GT3 RS has been spotted cold weather testing in the snow. Slotting above the current 911 GT3, the upcoming 911 GT3 RS will offer even higher performance potential including a more powerful engine and aerodynamic tuning.

Where the standard 911 GT3 is powered by a naturally aspirated 469-hp 3.8-liter boxer six-cylinder, the Porsche 911 GT3 RS will use an updated version of the 997-generation 911 GT3 RS 4.0 ’s 4.0-liter flat-six engine. That engine made 493 hp in the previous model, but is said to make 513 hp in the upcoming model. However, previous rumors suggested the RS might be turbocharged.

Porsche has updated the 911 GT3 RS with more scoops and vents compared to the standard GT3. The front fenders feature vents above and to the rear of the front wheels and a deeper front chin spoiler. It also adopts the 911 Turbo models’ air intakes ahead of the rear wheels, while an even larger rear wing has been fitted.

The upcoming Porsche 911 GT3 RS is expected to debut at the 2015 Geneva auto show in March. Check out the images below.
