Porsche took the opportunity at the 2016 Paris Motor Show to unveil the updated 911 GT3 Cup race car for the 2017 season. The new 911 GT3 Cup now gets the 4.0l flat-six naturally aspirated direct-injection engine with a 485PS tune. The 911 GT3 Cup also gets a revised bodywork with new front and rear aero bits to improve downforce.
Porsche also claims to have improved the reliability of the 4.0l engine which, in turn, reduces costs for its customers. The improvements include more rigid mounts for the valve drive rocker arms, a new central oil feed, more rigid crankshaft and an integrated oil centrifuge to optimise oil defoaming in the engine.
