Track-only limited edition model harkens back to the 935/78

The Porsche 935 has unveiled as part of celebrations surrounding the 70th anniversary of its first production car, the 356.

Based on the 911 GT2 RS, the body has been extensively restyled and re-engineered to pay homage to 935/78 race car nicknamed Moby Dick.

Most of the car's exterior body panels are unique and fashioned out of carbon-fibre-reinforced plastic. At the rear, the new 935 has a huge rear wing measuring 1909mm wide and 400mm deep. The car's wing mirrors are taken straight from the 911 RSR Le Mans race car.

Measuring 4865mm long, 2034mm wide (including mirrors), and 1359mm tall, the new 935 takes up more space in every dimension than the 911 GT2 RS. The two cars do share the same 2457mm wheelbase, though.

Powering the new 935 is a twin-turbo 3.8-litre six-cylinder boxer engine based on the one used by the road-going 911 GT2 RS, and making around 515kW of power.

The motor is hooked up to the rear wheels via a rigid suspension seven-speed dual-clutch transmission and a limited-slip differential.

The 935 rides on 18-inch wheels with Michelin racing tyres — 29/65 at the front, and 31/71 at the rear. Stopping ability comes courtesy of six-piston aluminium racing calipers and 380mm steel discs at the front, and four-pot calipers with 365mm discs at the rear.

Inside, the 935 features a single Recaro racing bucket seat with a six-point safety harness, safety cage, air conditioning, laminated wood gear knob, air jack system, and a fire extinguisher. A passenger seat is an optional extra.

The stability control, traction control, and anti-lock braking systems can be adjust or switched off via a map switch.

Just 77 935 race cars will be built, with prices in Europe starting from €701,948 ($1.1 million) exclusive of sales taxes.

The 935 is available in Agate grey, with the Martini livery seen here an optional extra.
