If every race in IMSA was a victory for Porsche, the series would be thoroughly un-interesting. After recent strong performances at Lime Rock and Elkhart Lake, the most recent round at VIR resulted in 7th and 8th place finishes for the Porsche GT Team. Because of VIR’s layout, with several very long straights, the Porsche 911 RSR’s lower top speed proved to be its downfall. The VIR race proved to be extremely clean, and with no periods with the safety car out, Porsche was unable to close the gap with the faster Fords, Corvettes and Ferraris. In GTD, the privateer Porsche teams were also kept off the podium by Lamborghini, BMW and Mercedes entries.
IMSA’s balance of performance system is not perfect, and while in previous years the teams running Vipers have been more adversely affected, this year is evidently Porsche’s turn. Per Laurens Vanthoor, “Our 911 RSR ran well and I had a good feeling in the car. Everyone could see that we didn’t have the pace, especially on the straights. The effect was particularly noticeable on this racetrack.”
Marco Ujhasi, the Director of GT Factory Motorsports is hopeful that the results of this race will encourage IMSA officials to review the results of this race, and help make the RSR competitive at faster tracks. The 911 RSR struggled at VIR thanks to the track’s lengthy full-throttle passages where the car’s lack of speed at the top-end was more apparent than at tighter circuits, like Lime Rock.
Despite the setbacks, the drivers seem optimistic about the future. With two races remaining in the season, the Porsche GT drivers have a long ways to go to move to the top of the standings, though we are hopeful that they can work toward stronger results as the season winds towards a close.
In the words of Gianmaria Bruni; “Aside from the lack of top speed, the race for us ran without any problems. The team worked well over the entire weekend. What came out in the end, however, is frustrating, but it’s no reason to hang our heads. As a team we have to pull together again, and do better at Laguna Seca.”
Porsche was also kept off the podium in GTD. The Weathertech sponsored GT3 R driven by Gunnar Jeannette and Cooper MacNeil managed a 4th place finish, leading three other GT3 Rs, including the #28 Alegra motorsports entry driven by Patrick Long and Daniel Morad.

put the motor back where it belongs and start winning again with a CAR not a diffuser sled!
Absolutely, since physics and current race technology favors optimizing the drivetrain mass in the front or rear and because Corvettes and BMWs are prime examples.
Uh, no. Ford and Ferrari are also mid-engine formats. The current RSR is lacking top speed due to lack of top end power. On paper, the RSR and the Ferrari 488 GTE are power equal. RSRs are more competitive at lower speed tracks, but aero efficiency might be a factor. IMSA juggles specs at specific events for more competitive racing. We'll see what happens.
Corvette Gran Sport, (650hp reported race trim)
Ford GT, 647hp (factory spec)
BMW M6, (est. 585hp reported race trim)
Porsche RSR, (470-510hp reported race trim)
Ferrari 488 GTE, (485-500hp, reported race trim limited)
