DUBAI, United Arab Emirates – Porsche has created a stripped-out racer for GT3 series - the new 911 GT3 R. It is based on the 911 GT3 RS road car and generates a whopping 368kW.
Porsche says its GT3 R features improved handling and safety, lightweight design, enhanced aerodynamics, and increased efficiency.
Porsche has always placed emphasis on perfect weight distribution and the GT3 R achieves this by lengthening its wheelbase by 8.3cm, a perfect recipe for, the automaker says, "flatter handling of corners".
RETAINS FAMED FLAT-SIX ENGINE
The GT3 R is distinguished by its double-bubble roof.
Replicating the lightweight body design of the 911 GT3 RS, the new racer uses an aluminium-steel composite structure. The GT3 R has many components made of light carbon-fibre composite material (CFRP).
All windows - and for the first time, the windscreen - consists of polycarbonate.
Powering the new 911 GT3 R is a four-litre flat-six unit used in the road-legal 911 GT3 RS.

Power from the rear-mounted engine is transferred to the rear wheels via a Porsche sequential six-speed constant-mesh gearbox. As in the GT road-going models of the 911, the driver changes gears via shift paddles conveniently positioned on the steering wheel.
TWO METRE LONG WING
The aerodynamics of the 911 GT3 R also follows the example of the road car. Its distinctive wheel-arch air vents on the front fairings increase downforce at the front axle. Measuring two metres in width by 40-cm's in depth, the rear wing lends aerodynamic balance.
From its 911 RSR big brother, the GT3 R has adopted the concept of the centrally-positioned radiator.
The brakes on the GT3 R were stiffened and to suit long distance racing. At the front axle, six-piston aluminium monobloc racing brake callipers combined with ventilated and grooved steel brake discs with a diameter of 380mm ensure outstanding braking performance.
Fitted at the rear axle are four-piston callipers and discs measuring 372mm.
The safety systems on this race car were aided by further-reinforced FT3 safety fuel cell was increased by 12 litres to 120, with the tank now featuring a fuel cut-off safety valve. The doors and the side windows can be removed, and the escape hatch in the roof is now larger.
In the event of an accident, the new racing bucket seat offers pilots even better protection.
