Motor Authority shared some revealing spy photos of the 2015 Porsche 911 RSR race car testing its new aero bits (and maybe more?) on the Nürburgring.
The current Porsche 911 RSR race car was first introduced for the 2013 World Endurance Championship season, competing in the GTE (Grand Touring Endurance) class. The road-going Type-991 is also receiving a facelift for next year, so it’s possible that some of those tweaks may also find themselves on this new Porsche 911 RSR.
The photographed prototype refuses to give even that much away, as it’s wearing heavy camouflage all around. The rear wing and front spoiler on this 2015 Porsche 911 RSR appear unchanged from the current car, as do the sleek, smooth side skirts. But the radiator inlet looks narrowed and trapezoidal on this prototype, as opposed to the broad, straight rectangle found on the previous RSR. There are also two smaller vertical slats, one on either side, possibly to scoop in cool air for the brake cooling ducts.
As for mechanical changes, nothing is known. Currently, the Porsche 911 RSR makes use of a lightweight sequential gearbox and normally-aspirated 460 HP, 4.0 liter flat-6. And so far, that pair seems to perform just fine.
