Porsche has unveiled its new customer racer for the worldwide GT3 series for 2019, basing it on the production version of the 911 GT3 RS. This, then, is the new 911 GT3 R, which the Stuttgart-based automaker says boasts a lightweight design and a "cutting-edge" water-cooled boxer engine.
The 911 GT3 R employs an aluminium-steel composite construction, while carbon-fibre reinforced plastic is used for the roof, bonnet, fairings, wheel-arches, doors, side and tail sections and the rear lid. Much of the cockpit, too, is fashioned from the lightweight material, while the windows make use of polycarbonate.
In the engine bay sits a 4,0-litre flat-six water-cooled engine, tuned to deliver 404 kW (as per class restrictions), with a single mass flywheel and a racing exhaust system.
Power is sent to the rear axle by means of a six-speed sequential transmission. Gears are selected via the paddle-shifters, which use an electronic shift drum actuator. The 911 GT3 R also boasts a mechanical slip differential and a racing clutch.
The track car's BBS alloy wheels are wrapped in Michelin slicks and frame 390 mm six-piston front and 370 mm four-piston rear multi-piece steel brake discs. Each axle has its own brake circuit, adjustable by the driver via a balance bar system.
The 911 GT3 R is available for order at €459 000 a pop (that's about R6,7-million), with first deliveries set to take place in December 2018.
