Porsche 911 R

The vehicle in detail

The front wings are constructed of carbon composite, the roof is magnesium, side and rear glass is polycarbonate, the exhaust system is moulded titanium and the sound insulation has been peeled.

The 911 R is bestowed with the full-fat 4.0-litre engine from the 991 GT3 RS, complete with 500hp and 8,800rpm redline.

This allows the Porsche 991 R to sprint from 0-62mph (0-100kph) in 3.8 seconds, 0.1 seconds faster than the 997 GT3 RS 4.0.

The 911 R has been blessed with rear-wheel drive only and a mechanical limited-slip differential, combined with Porsche Torque Vectoring, to ensure excellent traction through those huge 305-section rear tyres (the fronts measure up at 245, both on gorgeous 20-inch diameter centre-lock wheels).

Unusually, the 991 R retains the rear-wheel steering system seen on the 991.1 GT3 and GT3 RS. Porsche claims this is to provide the best blend of agility and stability that the electro-mechanical system has become renowned for.

Unlike previous cars from Porsche’s motorsport department, the 991 R has no fixed rear-end aerodynamics, shedding a rear wing in favour for a Carrera-style moveable decklid, the grill of which utilises a mesh covering, reminiscent of the iconic R-badged original.
