Porsche is set to release its most powerful factory-built street car ever, the GT2 RS. Possibly. Here are the spy shots.
So, how powerful is it? The twin-turbocharged GT2's flat six is rumored to be getting output rated in the 600-horsepower range (it could even more than the V10 Carrera GT's 605 horsepower) and is targeting a 7:22 lap time at the 'Ring. Value shoppers, on the other hand, will probably still want to stick with the ZR1.
Exterior differences to keep an eye on are mostly GT3 in nature: center-lock alloys, a hood-forward nose intake, mild front fender flares, a stripped interior with door pulls instead of handles, and a full roll cage.
