The limited-edition 911 GT3 R Rennsport, which is based on the Porsche 911 GT3 R of the 992 generation, has been unveiled at Rennsport Reunion 7 at WeatherTech Raceway Laguna Seca, California, the US. With prices starting at $ 1,046,000 (roughly Rs 8.69 crore), the new track-only car can be had with a powerplant sourced from the Porsche 911 GT3 R race car. A 4.2-litre naturally aspirated, 6-cylinder, boxer engine cranks out 611bhp, an increase from 557bhp – it is an out-and-out race car that is not road-legal and not even GT3 competition-legal. The water-cooled, 4-valve engine with direct gasoline injection is designed to run on E25 fuel. When operating with pistons and camshafts, the E25 fuels are said to improve vehicle performance. BMW says that the 911 GT3 R Rennsport revs all the way to 9,400rpm and tops out at 315km/h, thanks to a host of efficiency tweaks the Rennsport comes with. However, the engine can be tuned to run on conventional fuels. Note that the Rennsport will have a limited run of 77 units.
With the removal of the FIA GT3 regulations, a power output of up to 146bhp per litre is said to be a record-breaking value for the naturally aspirated engine of a GT racing vehicle. Power is transmitted to the rear wheels via a 6-speed sequential gearbox. While we are on the wheels, they are special 18-inch rims from BBS wrapped in Michelin tyres.
Porsche 911 GT3 R Rennsport: Weight Savings
When it comes to weight reduction, Porsche does away with the grille covers and select panels, leaving the mechanical bits including the exhaust system unobstructed. In the open version, the racing exhaust system with double tailpipes is claimed to offer a particularly emotional engine sound. Two silenced versions with catalytic converters are available for use on race tracks. Major weight-saving measures are being employed inside the vehicle, with the elimination of the air-conditioning system and front and rear passenger seats.
Porsche 911 GT3 R Rennsport: Styling
The Porsche 911 GT3 R Rennsport is designed by Grant Larson and Thorsten Klein, Porsche Style Team. It gets the same roof and bonnet as the GT3 R, however, it comes with a host of carbon fibre bits, along with reshaped vents, panels, and aero-optimised fins. The extended wheelbase and widened wheel arches sit on lowered springs and special 18-inch alloys. Besides, the conventional exterior mirrors have been replaced with a system of 3 cameras that feed displays in the cockpit.
Meanwhile, the Rennsport shares the rear wing and vertical spoiler with the legendary Porsche 935/77 and the Porsche 962 Le Mans race car, respectively. Prospective buyers have the choice of 7 different colours, including star ruby or signal orange. There are also three exclusive exterior designs that enable further individualisation: Rennsport Reunion Design, Flacht Design, and Speed Icon Design.
The vehicle's suspension system consists of double wishbones up front, a multi-link setup at the rear, and five-way adjustable racing shock absorbers from KW.
