In its first appearance in the 24 Hours of Le Mans last year, the Porsche 911 RSR scooped first and second place finishes in the GT-Class. Weissach's 991-based racer has been improved for 2014, and it started the season on a high as class victor at the Daytona 24-hour race.
The redesigned front end and the new rear wing provides optimal aerodynamic balance and therefore greater stability in fast bends. Even more precise steering response was attained by optimising front suspension kinematics and further improvements to the car's structural rigidity.
"Last season, we strove constantly to develop the car further. The better weight distribution, in particular, has had a positive effect on performance. The 911 RSR is now more stable over the rear axle and gives the driver a greater sense of trust. This allows the driver to probe performance limits faster," said driver Patrick Pilet.
Also new is the air induction system for the 470 hp 4.0 litre flat-six engine, which gets a new air filter geometry that contributes towards reducing the effects of contamination on power output. The new FT3 safety fuel tank with a lowered centre of gravity enables improved filling under race conditions.
Live telemetry that is permanently transmitted to the command station via the car's roof antenna ensures that engineers are always well informed of all relevant vehicle data with over 200 measurement values. In addition, all data is stored on a memory card in the vehicle.
The new 911 RSR is marked by broad flared wings and a deep cooling air channel at the front end. The new air flow system enables a centrally located radiator, which is more efficient than before.
The static cornering lights that are positioned very low in the front end improve the driver's view in bends. The reflective labels on cockpit controls, combined with anti-glare cabin lighting, improve legibility in the dark. The layout of switches on the new steering wheel was developed together with Porsche factory drivers.
For shorter repair times, a quick-change concept for body parts was tuned for long-distance racing. The nose, front lid and rear apron are attached with quick-action clamps and can be replaced in just a few seconds.
The updated 911 RSR will feature in endurance races together with the new Porsche 919 Hybrid, which combines two different energy recovery systems with a downsized V4 turbo engine.
