Porsche unveiled their mid-engine 911 RSR with race modifications at the Los Angeles Auto Show. What sets this 911 apart from others is that its 4.0-liter flat-six engine sits in front of the rear axle, rather than behind it. The 911 RSR was modified to meet Le Mans’ GTE requirements, where it will go against other mid-engine race cars like the Ford GT and Ferrari’s 488 GTE. The new 911 also ditches the previous steel-body construction for a lighter carbon fiber one, which attaches to the frame using quick-release fasteners. The 510 hp engine is mated to a six-speed sequential gearbox controlled via pedals located on the sides of the steering wheel for optimal driving performance. The 911 RSR is expected to make its racing debut at the IMSA opening in Daytona on January 28th. Check it out in the gallery above.
