“While retaining the typical 911 design, this is the biggest evolution by now in the history of our top GT model,”
says Head of Porsche Motorsport Dr Frank-Steffen Walliser.
The new 911 RSR is a completely new development: the suspension, body structure, aerodynamic concept, engine and transmission have all been designed from scratch. The engine concept has enabled the designers to install a particularly large rear diffuser. Combined with a top-mounted rear wing adopted from the LMP1 race car, the 919 Hybrid, the level of downforce and the aerodynamic efficiency were significantly improved.
For the first time, a Porsche GT race car features state-of-the-art assistance systems: the new 911 RSR is equipped with a radar-supported collision warning system, the so-called “Collision Avoid System”.
Even in the dark, the faster LMP prototypes are detected early enough and misunderstandings can be avoided. A new safety cage concept and a new, rigidly-mounted racing seat enhance driver safety. With the seat fixed to the chassis, the pedalry can now been moved and adjusted to fit the driver.
In the 2017 season, the factory is expected to run the new 911 RSR at 19 outings which equates to more than 140 hours of racing. With two factory-entries, Porsche will tackle the FIA World Endurance Championship (WEC) including the 24 Hours of Le Mans as well as the American IMSA Weathertech Championship. The new racer will celebrate its debut under the toughest conditions at the IMSA season opener in Daytona on 28-29 January. “We’re very well prepared for this,”
says Marco Ujhasi,
Head of GT Works Sport. “Since its first rollout in Weissach in March this year we’ve covered 35,000 test kilometres on racetracks in Europe and North America – that’s more than in the development of any other Porsche GT racer.”
