Technology 911 RSR

The most intense pressure of all:
the desire to excel.

When it comes to winning and when thinking about the future, we consider even the tiniest detail: every part of the vehicle, every single screw, and every second of every lap. A lightweight construction is clearly imperative. At 1,245 kg, the 911 RSR adheres precisely to the minimum weight specified by FIA World Endurance Championship regulations.

From the very start, the vehicle was designed to be suitable for long-distance racing. A new body structure with a longer wheelbase and new intake air ducting provides a platform for pure power that is just waiting to be unleashed. That is supplied by a water-cooled, horizontally opposed six-cylinder engine with a four-litre capacity. In figures this translates as 346 kW (approx. 470 hp) – limited by a restrictor. Output is transferred to the rear axle by a new six-speed sequential Porsche GT racing gearbox. Paddles deliver faster, more comfortable gearshifts.

To control the 911 RSR’s undeniable forward thrust, the brake system has six-piston monobloc fixed brake calipers at the front and four-piston units at the rear. Featuring a double-wishbone suspension at the front and multi-link rear axle, adjustable shock absorbers and anti-roll bars, the chassis superbly handles any manoeuvre – on straights as well as chicanes.

The axle geometry further optimises aerodynamics for even greater efficiency. Less drag coupled with increased downforce reduces the tendency to understeer and allows higher speeds when cornering.

From the development process onwards, another aspect has also received particular attention: safety. Our engineers’ uncompromising approach on this extreme interpretation of sportiness is evident from the weld-in roll cage, the overhauled FT3 safety tank and the optimised fire extinguishing system. Clear evidence of the importance that Porsche attaches to safety in motorsport, irrespective of the emphasis on lightweight construction.
