Porsche 911 991.2 RSR

Date of unveil by Porsche AG: November 16, 2016 (prototype May 12, 2016)

Engine: 4.0 B6 normally aspirated, 375 kW (depends on air restrictor)
Gearbox: Sequential, 6-speed with 3-disc clutch, magnesium casing
Weight: 1243 kg/2740 lb by regulations

Two decades after the different 911 GT1 cars - 993 GT1 '96, 993 GT1 Street, 996 GT1 '97, 996 GT1 Street, 996 GT1 Evo '98 - the mid-engined 911 is back! In order to install a proper diffuser under the rear end of the 991, the engine had to make room for it and the engine/transmission unit was rotated 180 degrees. The 911 was Caymanized, so to speak. Now you probably remember when the Cayman came out in 2005, it was said to handle better than the 911. The wheelbase of the 991.2 RSR was extended to 2516 mm. In comparison Cayman GT4 has 2484 mm, 991.2 GT3 Cup has 2456 mm and 991.2 Carrera/Turbo have 2450 mm. So, the rear wheels were moved back 1.3-2.6"/32-66 mm depending on how you look.

The extended rear diffuser, a top-suspended rear wing and the new side mirrors help to increase downforce with reduced drag. While the 911 GT1 cars were the ultimate mid-engined 911s with their turbocharged engines, the FIA rules restrict the engine power and there was no reason to equip the 991.2 RSR with a turbo engine. The normally aspirated 4-litre flat-6 was taken from the 991 GT3 R (used also in the 991 GT3 Cup 4.0).

The 991.2 RSR features a radar-supported Collision Avoid System which means now the faster LMP prototypes are detected behind early enough and misunderstandings can be avoided. On a cockpit monitor arrows indicate when vehicles are behind. Depending on the colour of the arrows, the driver knows whether the trailing car is coming closer or falling back. For the driver safety, the seat is now closer to the center of the car and is rigidly mounted (a new FIA rule). The movable pedal box (as well as brakes), come from AP Racing.

Between March and November 2016, the prototypes were tested for a total of around 22.000 miles/35.000 km which is more than with any previous Porsche GT racing car.

7 RSR were built by Porsche Motorsport for the 2017 racing season: 3 for testing, 2 for the FIA World Endurance Championship and 2 for the IMSA SportsCar Championship. It took 4 employees 10 working days to build one 911 RSR.

The GT LM class was so competitive at 2017 Daytona 24 hour race that seven (!) competitors finished the race within 7 seconds! While in the middle of the race Porsches were 1-2 in class, the final GT LM result was: 1. Ford GT, 2. 991.2 RSR, 3. Ferrari 488, 4. Corvette, 5. Ford GT, 6. 991.2 RSR, 7. Ford GT. Remember, all they covered 652 laps and were just 7 seconds apart after 24 hours! Thanks to BoP (Balance of Performance) rules the cars are very equal and this makes the races really interesting to follow.

Sports car racing is not a subject of public interest in USA and therefore Daytona 24 hour race cannot be compared to the Le Mans 24 and Nürburgring 24 hour races which gather more than 200.000 spectators. No spectators, no money, IMSA has to lean even on alcohol producers. The Daytona 24 drivers had to hold alcohol bottles in their hands on the podium. Really?

Although without race victories, Porsche won the 2017 IMSA North American Endurance Cup GT LM class in Drivers and in Teams categories (Ford won in Manufacturers category). At the NAEC the points are awarded many times in one race - after each of 3, 4 or 6 hours depending on the length of the race.

In the 2017 FIA WEC GT Driver's Championship Porsche drivers Richard Lietz/Frédéric Makowiecki scored second. In the GT Manufacturer's Championship Porsche scored third after Ferrari, Ford and in front of Aston Martin.


2018/2019 FIA WEC Super Season

FIA is in the process of moving its World Endurance Championship schedule for the seasons to start in the end of the year and to end next summer (the same has been practiced with Formula E from the beginning). To transform from the previous arrangement to the new, there has to be either a very short season or a longer-than-usual season. Instead of the usual 7 month season, the 2018/2019 "super season" will be 11 months long, but will not have more races. Actually there will be 8 races in the 2018/2019 season, while there were 9 races in the 2017 season, but the actual racing time is longer as the super season includes 2 Le Mans 24 hour races!

2018 Le Mans 24h

After withdrawal from LMP1 top class racing, Porsche factory team entered the 2018 Le Mans 24 hour race with 4 mid-engined 911 RSR - two cars that compete in the FIA WEC series and two IMSA Championship factory team cars:

911 RSR #91 (with "Pink pig" livery): Gianmaria Bruni, Richard Lietz, Frédéric Makowiecki
911 RSR #92 (with "Rothmans" livery): Kévin Estre, Michael Christensen, Laurens Vanthoor
911 RSR #93 (with Porsche Motorsport livery). Patrick Pilet, Nick Tandy, Earl Bamber
911 RSR #94 (with Porsche Motorsport livery): Timo Bernhard, Romain Dumas, Sven Müller

Bamber, Bernhard, Dumas and Tandy are overall Le Mans winners from earlier races, so there's not exactly anything to win for them. As Porsche factory drivers they cannot drive for other teams entering fast LMP cars, but anyway - Le Mans is Le Mans, an extreme experience always worth repeating, no matter in which car.

Porsche 911 RSR with classic livery for Le Mans 2018
2018 May 28 photoshooting of the 2018 Le Mans cars #91 and #92© Porsche

As Porsche wasn't fighting for the overall victory at the 2018 Le Mans race, they decided to please the fans with historic Porsche Le Mans liveries. The #91 got the livery of the Porsche 917/20 (that didn't even finish the 1971 Le Mans race, but standed out because of its strange body shape and livery). The #92 car got the "Rothmans" livery known from the Le Mans winning Porsche 956 and Porsche 962.

Porsche 911 RSR with classic livery for Le Mans 2018
Interestingly, such a shade of pink looks rather good on a racing 911. Expect this color to become available for the next 911 GTx street cars. The livery is 47 years old and a bit outdated in the sense that in 21st century it is not so cool to present publically how to cut someone's body into pieces (the original 917 livery showed how to cut a pig). © Porsche

The #94 car of Bernhard/Dumas/Müller had to retire because of the rear suspension damage. It could have been repaired, but Porsche was not searching to finish among the last ones. It had entered so many cars, so it just focused on the performance of the running 911s. The #93 car of Pilet/Bamber/Tandy had to pit for an alternator replacement which robbed 25 minutes and the chances for a good result. Both Porsche Motorsport liveried factory team cars had bad luck and the focus switched even more to the two 911s with historic liveries running up front in the GTE Pro category.

Porsches managed to win both GT classes. Dempsey-Proton Racing 911 RSR #77 driven by Matt Campbell, Christian Ried and Julien Andlauer won the GTE Am class. 18-year-old Andlauer became the youngest class winner in Le Mans history.

The #92 "Pink Pig" won the GTE Pro class, followed by the #91 "Rothmans" in front of Ford GTs, Corvette C7Rs, Ferrari 488 GTE Evos, Aston Martin Vantage AMRs and BMW M8 GTEs. The GTE Pro class was the most interesting and most competitive class at the 2018 Le Mans race as in the top LMP1-Hybrid class only one manufacturer (Toyota) had remained.
