2015 Porsche 911 (991) GT3 RS arrives at Geneva Motor Show

Article by Christian Andrei, on March 3, 2015

Porsche’s all-new 911 (991) GT3 RS was finally unveiled at the Geneva Motor Show, but as you may know already, the vehicle was shown in patent images last year. According to the German carmaker, the 911 (991) GT3 RS is powered by a 4.0-liter six-cylinder engine producing 500 hp (368 kW) and 460 Nm of torque. As a result, the new vehicle is able to accelerate from 0 to 100 km/h (62 mph) in 3.3 seconds, to 200 km/h (124 mph) in 10.9 seconds, while top speed is in excess of 300 km/h (186 mph).

Combined NEDC fuel consumption in the is 12.7 l/100 km. Other highlights of the vehicle includes functions such as declutching by “paddle neutral”, which is comparable to pressing the clutch with a conventional manual gearbox, but also speed limiting by Pit Speed button, customized for motorsport use.

Compared with the 911 GT3, the new vehicle is 10 kg lighter thanks to the roof made of magnesium, carbon fiber used for the engine and luggage compartment lids and other lightweight components made of alternative materials. Other characteristics of the 911 GT3 RS include the unique front wheel arch air vents that extend in the upper section of the wings, as well as the 30 centimetre wide recess that extends centrally over the CFRP bonnet and the magnesium roof.

Just like the 911 GT3, the new RS arrives with rear-axle steering and Porsche Torque Vectoring Plus with fully variable rear axle differential lock. The sporty theme is continued inside, where we find full bucket seats based on the carbon bucket seats found on the 918 Spyder, a Club Sport Package with a bolted-on roll cage located behind the front seats, preparation for a battery master switch but also six-point safety harness for the driver and fire extinguisher with mounting bracket.

As an option, Porsche offers the Sport Chrono Package, which includes the Porsche Track Precision app for smartphone. The app can be used in order to have lap times automatically measured via GPS.

Porsche says that the 911 (991) GT3 RS comes as standard with bi-Xenon hedlights, sports exhaust, dynamic engine mounts, Alcantara interior trim, sports bucket seats, 20-inch diameter front and 21-inch diameter rear centre-lock forged alloy wheels, Porsche Active Suspension Management (PASM), Porsche Torque Vectoring Plus (PTV) with rear limited slip differential, CDR audio system with 7-inch colour touchscreen, universal audio interface offering MP3 connectivity, automatic climate control, Porsche Stability Management (PSM), Porsche Vehicle Tracking anti-theft system, three-year warranty and three-year roadside assistance package.

In Germany, the 215 Porsche 911 (991) GT3 RS starts at 181,690 euros including VAT and will be launched in May. [source: Porsche]

Press Release

Porsche 911 (991) GT3 RS

The new Porsche 911 GT3 RS breaks down the barrier between street-legal sports cars and race cars more than ever. It is equipped with the maximum degree of motorsport technology that is currently possible in a street-legal 911.

Extensive modifications to its drive system, aerodynamics and lightweight design enhance performance even more than in the 911 GT3. And the 911 GT3 RS - now in its fifth generation - achieves these gains despite having already set standards in its class on the circuit racetrack ever since making its debut. With a lap time of under seven minutes and 20 seconds, it sets a new standard and even surpasses the Carrera GT super sports car's lap time of 2003.

Motorsport expertise is the reason for this superior performance. The Porsche 911 GT3 RS is powered by a four-litre six-cylinder engine with 500 hp (368 kW) of power and 460 Newton metres of torque, combined with a specially developed PDK transmission. The engine, which has the largest displacement and most power of any naturally aspirated engine with direct fuel injection in the 911 family, accelerates the high-performance sports car from zero to 100 km/h in 3.3 seconds and to 200 km/h in 10.9 seconds. Its NEDC combined fuel consumption is 12.7 l/100 km. Functions such as declutching by "paddle neutral" - which is comparable to pressing the clutch with a conventional manual transmission - and speed limiting by the Pit Speed button have been customised for motorsport use. On the one hand, they give the driver more freedom in terms of driving dynamics, and on the other hand they offer the driver more assistance when driving on a circuit racetrack.

Intelligent lightweight design: magnesium roof, carbon fibre wings and lids

The Porsche 911 GT3 RS is a masterpiece of intelligent lightweight design. Its roof is made of magnesium, the front wings, front lid and engine lid are made of carbon fibre, and other lightweight parts are made of alternative materials. This makes the RS model, which weighs 1,420 kg, around ten kilograms lighter than the 911 GT3. In addition, the lightweight roof lowers the sports car's centre of gravity which improves its excellent lateral dynamics. The body comes from the 911 Turbo, and it signifies its status as nearly a race car driving machine with its RS-specific aerodynamic add-on parts. The front spoiler lip, which extends nearly to the road, and the large rear wing reinforce its dominant look.

A 30 centimetre wide recess extends centrally over the CRFP bonnet and the magnesium roof. This feature is a stylistic reference to the recess on the luggage compartment lid of the classic 911 models with air-cooled engines, and today it identifies the two largest lightweight components in the 911 GT3 RS. Another characteristic is the unique front wheel arch air vents that extend into the upper section of the wings - just as in purebred motorsport cars. They increase downforce at the front axle.

Rear-axle steering and the widest tyres of any 911

The chassis of the Porsche 911 GT3 RS has been tuned for maximum driving dynamics and precision. Rear-axle steering and Porsche Torque Vectoring Plus with fully variable rear axle differential lock increase agility and dynamics, and the wider front and rear track widths enable even better roll stability than in the 911 GT3. In addition, the 911 GT3 RS comes with the widest tyres of any 911 model as standard. This results in even more agile turn-in characteristics and even higher cornering speeds.

The interior design of the Porsche 911 GT3 RS with Alcantara elements is based on the current 911 GT3. The driver and front passenger sit in full bucket seats made of visible carbon, which originate from the 918 Spyder. Other standard features are the Club Sport Package with a bolted-on roll cage behind the front seats, preparation for a battery master switch, and separately provided six-point safety harness for the driver and fire extinguisher with mounting bracket. The optional Sport Chrono Package, which features an integrated timer, also includes the Porsche Track Precision app for a smartphone. The Track Precision app can be used to have lap times automatically measured via GPS, and to log data on a smartphone for many driving parameters such as vehicle speed, lateral acceleration as well as longitudinal acceleration and deceleration. It manages this data and lets the driver share and compare it with other drivers.
