The new 911 GT3 R, which will be campaigned by customer teams in the GTD class of the IMSA SportsCar Championship, celebrates its race debut at Daytona mounted with the new ultra-modern four-litre flat-six engine with direct fuel injection. Porsche built the 500 hp racing car, based on the 911 GT3 RS production sports car, for GT3 series worldwide. In developing the vehicle, the engineers at Weissach paid special attention to consistent lightweight, better aerodynamic efficiency, reducing consumption as well as improved handling.
In addition, the wheelbase of the 911 GT3 R is now longer. The safety features underwent further optimisation and the costs of servicing and spare parts are now lower. From its 911 RSR big brother, the GT3 R has adopted the concept of the centrally-positioned radiator. By eliminating the side radiators, the position of the centre of gravity was improved, the venting of hot air through louvers in the front cover was enhanced, and the radiator is better protected against collision damage.
Sorry if I cannot express myself correctly, but I don't know English as good as I want, so my answers will probably be the same in many cases.
