World Premiere for Porsche 918 RSR Coupe Concept at Detroit Show

Porsche's return to the Detroit Show after a four year-absence is marked with the introduction of a new racing concept based on the company's 918 Spyder from last year's Geneva Salon. The 918 RSR is a two-seat mid-engined coupe, and according to Porsche, it demonstrates what happens when the technology fitted in the 911 GT3 R Hybrid race car and the design of the 918 Spyder concept are combined together.

The motorsports version of the 918 Spyder concept car gets a V8 engine based on the RS Spyder race car's 3.4-liter unit tuned to deliver 563HP at 10,300 rpm, and is linked to a six-speed racing transmission with shift paddles that feeds the rear wheels.

A pair of electrics motors mounted on the two front wheels each contribute 75 kW (102 hp), or a total of 204HP, lifting the combined output to 767HP. The German maker notes that the extra power from the electric motors is available for around eight seconds when the system is fully charged.

As with the 911 GT3 R hybrid racing car, the additional power from the electric motors, which is generated during braking, is stored in an optimized flywheel accumulator.

In the 918 RSR study, the two electric motors also offer a torque vectoring function with variable torque distribution to the front axle, which increases agility and improves steering response.

Aside from the coupe configuration with the fixed roof and the characteristic doors which open at an angle upwards, the 918 RSR also features an added air intake in the roof between the wing doors, a special aero package that includes air splitters beneath the front lip and a huge rear wing, plus slick tires on 19-inch wheels with single centre locking nut.

The interior of the road-spec 918 Spyder has also been modified and comes with a single figure-hugging bucket seat, while the passenger seat has been replaced by flywheel accumulator.

Porsche's Detroit Motor Show World Premiere Rumored to be 918 Coupe Racer

We already know that Porsche plans to debut a new model at the rapidly approaching North American International Auto Show (NAIAS) in Detroit next week, but the problem is that the German sports car maker is keeping its cards close to its chest about the type of vehicle it will unveil.

Adding to the many rumors already circulating on the internet, Bloomberg today reported that the model in question will be a racing coupe version of the 918 Spyder hybrid concept that was first shown at last year's Geneva Show.

Citing two people with knowledge of the matter, the news agency said that the car will be a two-seater concept coupe featuring a 600-horsepower V8. We'll remind you that the 918 Spyder, which was recently approved for a limited production run, gets a 500HP 3.4 liter V8 electro-enhanced by way of motors that add another 160 kW (218 hp).

We'll monitor the story and post an update if anything new arises, but for now, check out some renderings of a competition 918 made by a member of the Teamspeed forums in the video below.
