Porsche unveiled the new 935 racecar 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 700-horsepower competition vehicle will be produced in a limited number of 77 units.
The racecar’s technology is geared towards clubsport events and private training on racetracks. It is based on the street-legal 911 GT2 RS high-performance sports car. Like its historic predecessor, most of the body has been replaced or supplemented by carbon fibre reinforced polymer (CFRP) parts. With its streamlined extended rear, the new Porsche 935 measures 4.87 metres in length and has a width of 2.03 metres.
The spectacular aerodynamics are a completely new development, and pay tribute to the Porsche 935/78 Le Mans racecar, 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. Measuring 1909mm in width by 400mm in depth, the rear wing promotes aerodynamic balance.
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 racecar. 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These historical references are also visible in the cockpit. The knob on the gearshift lever has a laminated wood design and is reminiscent of historic Porsche racecars 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. Air-conditioning keeps the interior cool.
The new 935 is powered by a state-of-the-art 3.8-litre flat-6 twin-turbo engine, which is largely identical to the high-performance standard unit mounted in the road-legal 911 GT2 RS. Power is transferred to the 310mm wide rear wheels via a 7-speed Porsche Doppelkupplung (PDK) dual-clutch transmission with rigid mounts. Just as in production models such as the 911 GT2 RS and GT3 RS, the driver changes gears via conveniently positioned shift paddles located on the steering wheel.
Typical of the 911, the weight distribution ensures excellent traction and braking performance. Six-piston aluminum monobloc racing callipers on the front axle, in combination with internally ventilated and grooved iron brake discs with a 390mm diameter, provide excellent braking performance. The rear axle is fitted with four-piston calipers and 355mm discs.
Like the road-legal 911 GT2 RS, the 1380kg 935 is equipped with PSM (Porsche Stability Management) including traction control as well as an anti-lock braking system (ABS). Thanks to a so-called map switch, these assistance systems can be adjusted separately or switched off completely, depending upon the track situation.
