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 700-horsepower competition vehicle will be produced in a limited number of 77 units. “This spectacular car is a birthday present from Porsche Motorsport to fans all over the world,” says Dr. Frank-Steffen Walliser, Vice President Motorsport and GT Cars for Porsche AG. “Because the car isn’t homologated for any series, engineers and designers didn’t have to follow the usual rules and thus had freedom in the development.”
The race car’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-fiber-reinforced polymer (CFRP) parts. With its streamlined extended rear, the new Porsche 935 measures 191.5 inches (4.87 meters) in length. The width of the exclusive clubsport race car is 80.1 inches (2.03 meters).
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 modeled 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These historical references are also visible in the cockpit.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 race cars such as the 917 and the 909 Bergspyder as well as the street-legal Carrera GT super sports car. The carbon fiber steering wheel and the color 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-liter flat-six-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 310 millimeter wide rear wheels via a seven-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 calipers on the front axle, in combination with internally ventilated and grooved iron brake discs with a 390-millimeter diameter, provide excellent braking performance. The rear axle is fitted with four-piston calipers and 355-millimeter discs.
Like the road-legal 911 GT2 RS, the 3,042 pound (1,380 kilogram) 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.
The new Porsche 935 can be ordered now from 701,948 Euro plus country-specific VAT. In the U.S., this non-street-legal vehicle will be imported and sold by Porsche Motorsport North America of Carson, California. U.S. specific pricing will be announced at a later date. Customers will receive their vehicles from June 2019 at exclusive delivery events.
