Porsche breaks with decades of tradition and builds a racing 911 that doesn't hang its engine out behind the rear axle.
Porsche pulled the wraps off of the new 911 RSR endurance race car.
However, there's more than meets the eye here. The new RSR breaks from 911 tradition and moves the engine amidships.
This may not seem like a lot, but it's a wild departure from the 911's longstanding rear-engine layout.
By moving the engine inboard, the RSR gains better weight distribution and room is freed up for a massive rear diffuser.
Behind the wheels are aluminum monoblock brakes that are fed cool air by dedicated vents.
In addition to the diffuser, a new rear spoiler has been added that is inspired by the 919 LMP1 prototype racer.
The 911 RSR's 4.0-liter flat-six engine makes up to 510 horsepower depending on the restrictor required by the racing series.
Two examples are being built to compete in endurance racing, including the 24 Hours of Le Mans and the Daytona 24 Hours.
