More about the car

One of the priorities in the development of the 991 RSR was an evenly balanced weight distribution. The centre of gravity is also significantly lower than that of its predecessor. Carbon fibre played a crucial role in the new design. The front and rear mudguards, front and rear lids, doors, underbody, wheel arches, rear wing, dashboard and centre console are made of the very light and strong material. Moreover, all windows are made of particularly thin and light polycarbonate. Also contributing to the weight reduction is the lightweight lithium-ion battery known from the GT road-legal models.

Ongoing improvements have been made on the 911 RSR for the 2014 season. The revised front end and the new rear wing provide an optimised aerobalance, which allows greater stability in fast corners. Through optimising the front axle kinematics, a more precise steering sensitivity and hence better control of the vehicle in slow and medium speed corners were achieved. The further improved structural stiffness ensures more precise handling. Another new feature is the extensively optimised engine air-intake thanks to improved air filter geometry that contributes to reducing loss of performance due to contaminants. The new FT3 safety fuel tank with a lowered centre of gravity makes it easier to refuel under race conditions.

In order to keep the engineers in the pits up-to-date with all relevant vehicle data, the live telemetry transmits more than 200 different measurements straight to the pit wall stand via an antenna on the roof. Additionally, all data are stored on a memory card onboard the vehicle.

“The 991 RSR was optimised in many areas. Thanks to the wider rear wheels and the sophisticated aerodynamics, the car has become more consistent over a stint,” says Porsche works driver Joerg Bergmeister. “This is without doubt the best 911 I’ve ever driven. It still feels like a 911, but it’s better than the predecessor in almost every way. And on top of that, in my view it’s the most beautiful, spectacular 911 there has ever been.” His teammate Patrick Pilet added: “We constantly worked on improving the vehicle over the last season. The improved weight distribution in particular has had a positive effect on performance. The 991 RSR is now even more stable at the rear and gives you as a driver more confidence. And this allows us to go to the limit quicker.”
