The new 935 is powered by a state-of-the-art 3.8-litre six-cylinder 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 rear engine via a seven-speed Porsche Doppelkupplung (PDK) with rigid gearbox suspension at the 310-millimetre-wide rear axle. Like in the GT road models of the 911, the driver changes gears via conveniently positioned shift paddles on the steering wheel. Typical of the 911, the weight distribution ensures excellent traction and braking performances. Six-piston aluminium monobloc racing callipers on the front axle in combination with internally ventilated and grooved steel brake discs with a 380-millimeter diameter provide excellent deceleration values at the front axle. The rear axle is fitted with four-piston callipers and 355-millimeter discs.

Like the road-legal 911 GT2 RS, the 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 on the driving situation.
