The fastest and most powerful road-approved 911 is ready for launch. The new Porsche 911 GT2 RS celebrated its world premiere at the Goodwood Festival of Speed in the U.K. (30 June to 2 July). At the heart of this high-performance sports car is a 690bhp bi-turbo flat engine.

Weighing in at 1,470kg with a full fuel tank, the lightweight two-seater accelerates from 0-100km/h in 2.8 seconds. The rear-wheel drive coupe has a top speed of 340km/h, and with its near-motorsport drive technology, the new 911 GT2 RS trumps its 3.6-litre predecessor by 79bhp and achieves a torque of 750Nm (an increase of 50Nm). 

The engine builds on that 3.8-litre in the 911 Turbo S at 573bhp.

In order to increase performance, large turbochargers push an increased volume of process air into the combustion chambers. A new additional cooling system delivers optimum cooling at peak loads and, at very high temperatures, sprays the charge-air cooler with water. This causes the gas temperature to fall in the overpressure range and ensures optimum power output, even under extreme conditions.

The customised GT seven-speed double-clutch PDK transmission in the new GT2 RS enables power to be transferred with uninterrupted traction. What's more, the specially-developed exhaust system is made from extra-lightweight titanium, weighs around 7kg less than the system used in the 911 Turbo and delivers an emotional sound without precedent. 

Like all GT sports cars, the new top model features a specially calibrated Porsche Stability Management with a Sport mode that is tailored to provide optimal driving dynamics.

Powerful air intakes and outlets and the imposing rear wing emphasise that the vehicle's aerodynamics have mastered both form and design. The large, wide wheels ensure outstanding braking and cornering forces. The 911 GT2 RS features Porsche Ceramic Composite Brakes as standard.

The front wings, wheel housing vents, outer shells on the Sport Design exterior mirrors, air intakes on the rear side sections and parts of the rear end are made from carbon fibre-reinforced plastic, as are many of the interior components. The bonnet is also made from carbon to make the vehicle as lightweight as possible, while the standard trim roof is made from magnesium.

Performance can always be cranked up a notch - even on the 911 GT2 RS.

That's why the Porsche engineers have developed the optional Weissach package, which provides a weight saving of around 30kg. The package includes additional elements made from carbon fibre-reinforced plastic and titanium.

For instance, the roof and the anti-roll bars are made of carbon, and so are the coupling rods on both axles. Magnesium wheels reduce both the gross weight and the unsprung weight, providing a greater wealth of impressive chassis properties.

For the first time ever, Porsche Design is celebrating the debut of the high-performance sports car by releasing a special-issue watch. Offering a nod to the world of motorsport, the 911 GT2 RS watch is exclusively available to owners of the new vehicle and can only be ordered in conjunction with the new GT model at a Porsche Centre from now on.

The 911 GT2 RS will be available in Singapore from $1,211,688. Prices include a five-year free maintenance and warranty program, market-specific equipment, GST and CEVS fees/rebates but exclude COE. It covers all servicing needs as well as maintenance and repair costs, including regular wear and tear. Prices are subjected to change without prior notice. Terms and conditions apply.
