Porsche 911 R

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.

The front and rear ends are almost directly carried over from the Porsche 991.1 GT3 (albeit with a revised lip spoiler at the front).

Inside, on top of the short throw precise carbon-clad gear lever and clutch pedal, the highlights are the 918-style carbon bucket seats., which are finished in black leather with ‘Pepita’ houndstooth fabric centres, which look and feel fantastic.

The Porsche 991 R also gets it’s own 360mm version of the Sport GT steering wheel, complete with black rather than silver trim pieces, while the rear seats have been deleted.
