CORRECTION: The below text is incorrect, as it appears that this is actually a WC-997GT3. Sorry about that!
Porsche 911 GT2 RS modified by Global Motorsports Group (GMG Racing). Not certain what the specifics for this car is, but I know other WC-GT2RS’s have something like 690 horsepower and 630lb-ft of torque with a top speed of around 210mph and a 0-60mph time of right around three seconds flat.
