Lime Rock Park hosts round seven of the most important and popular sports car series on the North American continent on 22 July. With a length of just 2.414 kilometres, the racetrack in the idyllic rural region of the US state of Connecticut is the shortest on the championship calendar. The Porsche GT Team fields two 911 RSR in the GTLM class. The racer is based on the seventh generation of the iconic 911 sports car and was a completely new development of Porsche Motorsport in Weissach. Two Porsche customer teams tackle the GTD class with the 911 GT3 R, the winning car of the Daytona 24-hour race. This year at Lime Rock only these two categories with a total of 24 cars will compete, hence the overall winner will definitely be a GT vehicle.

The 911 GT3 R

The 911 RSR fielded in the IMSA SportsCar Championship, which posted its first pole position recently at Bowmanville, is a completely new development. Depending on the size of the restrictor, the motor, which is now positioned in front of the rear axle, puts out around 375 kW (510 hp). The level of downforce and the aerodynamic efficiency were significantly improved. The 911 GT3 R, mounted with the ultra-modern four-litre, flat-six engine with direct fuel injection, was designed by Porsche for worldwide GT3 series on the basis of the 911 GT3 RS production sports car. The more than 368 kW (500 hp) customer sports racer celebrated a class victory at this year’s 24 Hours of Daytona.
