New 911 GT3 R Revealed
Porsche has unveiled a new customer racer based on the 911 GT3 RS – the second generation 991 GT3 R. The 550hp machine was revealed ahead of the Nürburgring 24 Hours which takes place this weekend. The car features an aluminium-steel construction, its roof, front hood and fairing, wheel arches, doors, side and rear (as well as the rear lid and interior trim) are made of lightweight carbon fibre. Its windows are polycarbonate.
The new 911 GT3 R is powered by the latest version of Porsche’s four-litre flat-six engine, it is largely identical to the unit found in the road-legal GT3 RS. Utilising Direct Fuel Injection (DFI) operating at pressures up to 200 bar, it also features variable valve timing but it is also said to offer significantly better driveability than its forebear. Six throttle butterflies ensure the new 911’s engine response is more precise, power is transferred via a sequential six-speed constant-mesh gearbox with an electronic shift actuator. The clutch is electro-hydraulically controlled, which eliminates the need for a third pedal and assists fast racing starts.
Aerodynamics play an important role with both the road and race car, this racing version features a rear wing that measures 1.9 metres in width,= lending increased aerodynamic balance. The tyre circumference at the front axle has grown from 650 to 680mm, together with double wishbone suspension this aids superior braking performance. Talking of brakes, the system on this new 911 GT3 R underwent modifications (six-piston, 390mm front, four-piston, 370mm rear), it now offers more precise control of the ABS system.
In order to improve pit stop performance, the 120-litre FT3 safety fuel cell can now be refilled from the left or the right side of the car depending on the circuit layout. A new racing bucket seat affords drivers better protection in the event of a collision, while the adjustable pedal box helps ensure the driver’s centre of gravity is optimised for increased safety in the event of an impact. In addition, drivers will be protected thanks to a carbon fibre Kevlar aluminium side impact element positioned in the driver’s door.
The inside has been redesigned over the first generation car. All of the controls have been aligned to suit the needs of the driver and, for the first time, the 911 GT3 R features air-conditioning. Thanks to a direct connection to the seat and driver’s helmet, the A/C system enables efficient cooling of the driver, which in turn helps them maintain concentration and therefore a constant performance over a race distance.
The new 911 GT3 R can be ordered now for 459,000 Euro (plus country-specific VAT), first deliveries are expected from December. All technical details and data are provisional until final approval via the FIA.
