The changes could make the 911 a competitor against the Ford GT on track.
The 2017 Porsche 911 RSR GTE could make the radical switch to a mid-mounted, biturbo engine when the racer debuts at the Daytona 24 Hours in January. New spy shots from testing at Monza show that the body has side intakes, which are very similar to the ones on the production 911 Turbo. This is among the next RSR’s first laps away from Porsche's Weissach test track, Sportcar365 reports.
The two spy photos show the new racer's profile and roof. From the side, you can see the large intakes in the swollen rear fenders. The current, naturally aspirated RSR has much smaller holes there. The extra area could help the upcoming model feed cool air into a biturbo flat six. The wing also has long uprights that raise it as high as the roof.
The shot from above demonstrates how Porsche tweaks the racer’s shape, including adding a series of vents at the roof’s rear. According to Sportscar365, the company has waivers with the FIA and ACO organizing bodies to move the RSR's engine and gearbox compared to the production model. The adjustments might make the racing 911 more competitive against mid-engine competitors from Ford and Ferrari.
Porsche released official photos of the 2017 RSR in May, but the images didn’t reveal the car's rear. The company also didn’t mention any technical details about it. After debuting at Daytona, the racer will compete in the IMSA WeatherTech SportsCar Championship in the United States and the FIA World Endurance Championship.
The brief video below doesn’t provide a very good look at the RSR, but the clip is a chance to hear the new racer on track.
