The development of the new Porsche 911 RSR
At the ten-hour Petit Le Mans race contested on the tradition-steeped Road Atlanta racetrack last Saturday, the new 911 RSR scored the first two championships. There, Patrick Pilet (France) and Dirk Werner (Germany) won the prestigious North American Endurance Cup with the 510 hp GT racer from Weissach. The long-distance classics that count towards this performance and reliability competition in international GT racing are Petit Le Mans, Daytona, Sebring and Watkins Glen. The Porsche GT Team also won the team classification at the series’ four premier races, where teams and drivers had to underline their consistency and reliability over a total of 52 hours. The first highlight of the new 911 RSR’s maiden season came on 22 July, scoring its first victory at the Lime Rock round of the IMSA SportsCar Championship.
“Winning the North American Endurance Cup has shown that we were always at the front at the right time at the major endurance races and, above all, we’ve also underlined the reliability of our new 911 RSR over the season. For a maiden season with a completely new car, this was a good performance,” said Dr Frank-Steffen Walliser, Vice President Motorsport and GT Cars. For Marco Ujhasi, Director GT Factory Motorsports, the first race victory for the new 911 RSR was “a particularly emotional moment. We’ve all worked towards this day with total commitment and absolute passion.”
Completely new development
The 911 RSR, which the Porsche GT Team also campaigned in this year’s Sports Car World Endurance Championship WEC, is a completely new development. The key new feature is the positioning of the engine in front of the rear axle. Thanks to this, the weight distribution improved and at the same time more space was freed up to fit a larger diffuser at the rear which generates significantly more downforce.
The development of the new 911 RSR began in early 2015. Initially, a small team with representatives from individual divisions was engaged in analysing the “lessons-learnt” potential of the predecessor model as well as studying the sporting and technical regulations. From their findings, a new vehicle concept was then tailored to the requirements of modern long-distance racing. And race drivers were included in the development process earlier than ever before. “The drivers have to feel comfortable in the car,” said Marco Ujhasi. “Only a driver who still feels fresh at the end of a gruelling stint will be able to give the top performance that is needed to be successful in such a tough competitive environment.”
