Hearing it once will leave it etched in your mind—the inimitable sound of the current 911 RSR. The sharp, ecstatic scream of a four-liter, high-speed flat engine whose combustion acoustics are unfiltered by any turbocharging as it cuts through the Le Mans night at more than 300 kmh. Goose bumps of the purest sort. Unmistakable. To the ears of true
Largest GT contingent of all time
The hundreds of thousands of pilgrims who will flock to the high-speed extravaganza of Le Mans at the Circuit des 24 Heures on June 16 and 17 of this year can look forward to a special auditory experience. Ten 911 RSRs seek to turn the highlight of the endurance year into a festival of speed. Four
Exploiting the tiniest of liberties
The current RSR, which is based on the 911 GT3 RS, stands at the cutting edge of this evolutionary process. The core element of its steel chassis rolled off the production line in Zuffenhausen—standard series production. Specialists at
Nothing was sacred to the designers, including the placement of the approximately 510 hp naturally aspirated engine. The assembly is no longer in the rear of the car but in front of the rear axle. This creates space for the larger diffusor, which generates downforce without any significant impairment of the aerodynamics. The RSR can therefore take fast curves even faster while the all-important drag at top speeds remains essentially constant—a particularly important advantage on the long full-speed stretches in Le Mans. Additional downforce on the rear axle is generated by the top-mounted rear wing. This also notably improves the aerodynamic efficiency.
In 2018 the 911 RSR is already entering its second season, which will be an extraordinary one as far as the FIA World Endurance Championship is concerned. The first race will take place in May of 2018 and the last in June of 2019. That means the season will feature two twenty-four-hour races in Le Mans, in addition to the twelve-hour race in Sebring, Florida, plus five six-hour contests. Aside from their guest appearance in Le Mans, two of the four factory RSRs will enter all twelve races in the IMSA WeatherTech series in North America instead of the World Endurance Championship.
Improvements for standard series models
Given this marathon program,
No matter how the current season turns out for the 911 RSR, one thing is already clear: the insights that
