German sportscar maker Porsche has unveiled a mid-engined version of the 911 sports car at the 2016 Los Angeles Auto Show in the form of the 911 RSR.
The 911 RSR is Porsche's latest track day weapon which will compete in the GTE class of the World Endurance Championship for 2017.
Powering the 911 RSR is a mid-mounted naturally aspirated 4.0-litre six-cylinder boxer engine that cranks out 503bhp.
Thanks to its extremely low weight of 1243 kilograms, the 911 RSR has a power to weight ratio of around 405bhp/ton.
The engine sends the power to the massive rear wheels through a paddle shifter controlled six-speed sequential gearbox, which sits in a lightweight magnesium housing.
The new 911 RSR features a whole host of crazy aero bits like the giant rear wing from the 919 LMP1 race car and an even more insane diffuser sitting under the rear end that maximise downforce and will help it blast through corners at crazy speeds at Le Mans.
To ensure that the drivers inside remain safe and avoid manically approaching LMP1 racers battling it out for the lead, the RSR is fitted with a radar-supported "Collision Avoid System," which warns drivers of approaching traffic.
The 911 RSR will make its competitive debut at the 24 Hours of Daytona endurance race in the United States in January 2017.
