The most powerful Porsche 911 of all time


The new Porsche 911 GT2 RS made its world premiere at the 2017 Goodwood Festival of Speed. The heart of this high-performance sports car is a 515 kW (700 hp) biturbo boxer engine.

Weighing 1.470 kilos, including a full fuel tank, this lightweight two-seater accelerates from 0 to 100 km / h in 2,8 seconds. The rear-wheel drive coupe has a top speed of 340 km / h and, thanks to its close-to-race technology, it outperforms its predecessor's 3.6-liter powerplant by 59 kW (80 hp) and achieves a maximum torque of 750 Nm, which means a gain of 50 Nm.

The engine is based on the 3.8-liter in the 911 Turbo S, which develops 427 kW (580 hp) in the latter. To increase performance, large turbos have been used, which press and increase the volume of intake air directed to the combustion chambers. A new cooling system achieves optimum performance at peak engine loads and, at very high temperatures, sprays the water-cooled intake air. This causes the gas temperature to drop in the overpressure phases and ensures perfect power, even under extreme conditions.

 The seven-speed dual-clutch gearbox (PDK) has been adapted to the new GT2 RS, so it can transmit power without interruption in traction. In addition, the specially developed exhaust system is made of ultralight titanium, which is why it weighs around seven kilos less than the one used in the 911 Turbo and provides an unprecedented exciting sound.

In the world of super sports cars, cornering speed is on another level. To be reliable in this regard, the 911 GT2 RS uses an impeccable racing chassis, with a steered rear axle, and ultra-high performance tires (Ultra High Performance, UHP).

Like all GT sports cars, the new top-of-the-range model features the specially calibrated PSM system, with a Sport mode tuned to provide optimal driving dynamics. Powerful air intakes and outlets, along with the imposing rear spoiler, ensure that the vehicle's aerodynamics meet both design and function.

The large and wide tires (265/35 ZR 20 at the front and 325/30 ZR 21 at the rear) ensure exceptional braking and cornering. The 911 GT2 RS comes standard with Porsche Ceramic Composite Brakes (PCCB). The front wing vents, the Sport Design exterior mirror housings, the rear side air intakes and some parts at the rear are made of carbon fiber reinforced plastic (CFR), just like many interior components. The bonnet is also made of carbon to make the car lighter, while the roof is made of magnesium as standard. Both body parts feature a domed design.

Performance can always be increased, even in a 911 GT2 RS. This is the reason why Porsche engineers have developed the optional Weissach package, with which the car is lightened by around 30 kilos. The package includes additional elements made of carbon fiber reinforced plastic and titanium. For example, the roof and anti-roll bars, plus the tie rods on both axles. Magnesium wheels reduce both overall weight and unsprung masses, further enhancing the impressive chassis properties. The carbon-textured hood and roof are stamped with a center strip in the same color as the vehicle, giving it a different look.

The interior of the 911 GT2 RS is dominated by red Alcantara, black leather and interior trim with a carbon finish as standard. The GT2 RS's sport paddle steering wheel enables quick and sporty gear changes. Driver and passenger will experience the dynamism of this high-performance sports car in the bucket seats, also finished with a braided carbon fiber. As with all 911s, the Porsche Communication Management (PCM) is the central control unit for audio, navigation and communication. The Connect Plus module and the Porsche Track Precision app are also included as standard, allowing detailed recording, viewing and analysis of driving data on a smartphone.

The optional Chrono Package extends the capabilities of the PCM by including a performance display, which can be used to display, save and evaluate your times on the track. In addition, it comes with a lap trigger. By using the Porsche Track Precision app in conjunction with the external start and finish marks for the main straight of the circuits, this lap trigger enables the driver to record the times of each lap with great precision.
