Porsche 935 - the racecar with an air conditioner

By CARSIFU | 28 September 2018


ATLANTA: Porsche has unveiled the new 935 race car on the occasion of “Rennsport Reunion VI” at WeatherTech Raceway Laguna Seca in California.

Featuring a body reminiscent of the legendary Porsche 935/78, the 700hp competition vehicle, based on the street-legal 911 GT2 RS, will be produced in a limited number of 77 units.

The racecar isn't meant for any particular race series, which means Porsche's engineers were not restricted to following homologation rules and had freedom in the development.

The race car’s technology is geared towards clubsport events and private training on racetracks.

Like its historic predecessor, most of the body has been replaced or supplemented by carbon-fibre reinforced polymer (CFRP) parts.

The aerodynamics are a completely new development, and pay tribute to the Porsche 935/78 Le Mans race car, which fans dubbed “Moby Dick” due to its elongated shape, massive fairings, and white base colour.

The distinctive wheel arch air vents on the front fenders, which also are a feature of the Porsche 911 GT3 R customer racing vehicle, increase downforce at the front axle.

Many exterior details are a salute to successful vehicles from the company’s motor racing history: The aerodynamically enhanced rims echo those of the 935/78, with the LED rear lights on the rear wing endplates adopted from the 919 Hybrid LMP1 race car.

The side mirrors come from the current Le Mans-winning 911 RSR, with the exposed titanium tailpipes modelled on those from the Porsche 908 from 1968.

These historical references are also visible in the cockpit with the knob on the gearshift lever having a laminated wood design and is reminiscent of historic Porsche race cars such as the 917 and the 909 Bergspyder as well as the street-legal Carrera GT super sports car.

The carbon fibre steering wheel and the colour display behind it have been taken from the 2019 911 GT3 R.

A massive safety cage combined with a racing bucket seat and a six-point safety harness help ensure maximum safety. A second seat for a passenger is available as an optional extra while the air conditioning keeps the interior cool.

The new 935 is powered by a 3.8-litre flat-six twin-turbo engine, which is largely identical power plant in the 911 GT2 RS.

Power is transferred to the 310mm wide rear wheels via a seven-speed Porsche Doppelkupplung (PDK) dual-clutch transmission with rigid mounts and just like in the 911 GT2 RS and GT3 RS, changes changes are conducted via paddle-shifters.

Braking performance comes from its front six-piston aluminum monobloc racing calipers that bite down on the 390mm internally ventilated slotted discs, while the rear gets four-piston calipers for its 355mm discs.

Like the road-legal 911 GT2 RS, the 1,380kg 935 is equipped with Porsche Stability Management system including traction control and anti-lock braking system (ABS).

Thanks to a so-called map switch, these assistance systems can be adjusted separately or switched off completely, depending on track situations.

The new 935 is currently available for order taking from 701,948 Euro with deliveries starting in June 2019.
