New Porsche 911 RSR successfully concludes test drives
Season preparations on the finish straight

Stuttgart. The development of the new Porsche 911 RSR based on the current generation 991 model is nearly complete. On the Sebring International Raceway in Florida/USA the GTE race car from Weissach completed another successful test on Thursday. The successor to the Porsche 911 GT3 RSR will be run exclusively by the Porsche AG Team Manthey works squad at the 24 Hours of Le Mans and in the World Endurance Championship (WEC). The vehicle celebrates its race debut on April 14 at the WEC season-opener in Silverstone.

Sharing driving duties at Sebring were Porsche works drivers Richard Lietz (Austria) and Patrick Pilet (France). Lietz contests the WEC including Le Mans with Marc Lieb (Germany) at the wheel of the 911 RSR with the starting number 92. Patrick Pilet joins forces with Joerg Bergmeister (Germany) in the number 91 vehicle. At the first two WEC rounds in Silverstone and Spa-Francorchamps as well as at Le Mans, they receive backup from their factory pilot colleagues Romain Dumas (France/No. 92) and Timo Bernhard (Germany/No.91).

“We are very pleased with how the testing has gone so far,” said Porsche’s Head of Motorsport Hartmut Kristen. “Our goal is to be well prepared for the challenges of the very strong GTE class in the WEC and at Le Mans. The circuit in Sebring is very well suited to put a new vehicle through some demanding trials. For this reason, a test in Sebring is a very good rehearsal for one of the toughest races of all, the 24 Hours of Le Mans. Until the season kicks off in Silverstone, we will conduct some final tests on other race tracks so that our new 911 RSR is well and truly ready for the World Endurance Championship season.”

it generates 460 hp

 

That's pretty sexy !!

 

So it's an 991 RSR but they are using the 3.8 this year?

 

Hi Mike,

thanks..I know this article..and its also what I suspected to happen..but since there was so much about the new 991 GT3.."which will be with a new engine..and this new engine will be used in racing etc"..

If you wanna know my guess, there will be no new engine for the 991 GT3..its the 991S engine..Porsche will use the current RSR engine for another 2-3 years..and replace it then by the new 8 Cylinder Boxer..thats the only solution. Replacing one 6 Cylinder with another 6 Cylinder ..doesnt make much sense probably..

Well see..

 

Yes, I don't think the 4.0L is legal in the classes the car will be running in WEC events.

I could be wrong, however. Don't know for certain.

 

4.0L is legal. Max is 5.5L

 

So this tells us what the side intakes are going to be shaped like on the turbo, correct?

 

Without dishing too much, Porsche will hang a little longer with the 3.8. While I love the 4.0 and it's power, etc., there are some realiability issues with the motor at present in racing. Won't get into much detail beyond that. The 4.0 is a better motor on the short tracks, but the 3.8 is seeing a little more top end.
