Porsche unveils the most powerful 911 of all time

Porsche has taken the wraps off the 2017 911 GT2 RS, which is the most powerful car ever produced under the 911 lineage. The car made its world premiere at the Goodwood Festival of Speed in the UK.

Powering the GT2 RS is the same 3.8-litre flat-6 engine that is found under the 911 Turbo S. However, Porsche engineers have used larger turbochargers and an additional cooling system in the GT RS, which has helped in bumping its power output up to 691 BHP, while the torque produced is rated at 750 Nm. The bi-turbo engine is mated to a customised GT 7-speed double-clutch transmission (PDK) that transfers power to the rear wheels of the two-seater coupe. Porsche claims that this powertrain is capable of accelerating the 911 GT2 RS from 0-100 km/h in 2.8 seconds. The car has a claimed top speed of 340 km/h.

The GT2 RS has various features that help in delivering the said performance figures. It is built on a racing chassis and comes with rear-axle steering that is said to aid agility. It is equipped with Porsche Ceramic Composite Brakes (PCCB) as standard. Porsche has also used light-weight elements in the car's construction to save weight. The kerb weight of the vehicle is 1,470 kg. The bonnet is made from carbon-fibre while the roof is built out of magnesium. Additionally, the front wings, wheel housing vents, outer shells of the ORVMs, air intakes on the rear side sections and parts of the rear end are made from carbon-fibre reinforced plastic (CFR). The exhaust is constructed using extra lightweight titanium and thus weighs around 7 kilograms lesser than the system used in the 911 Turbo.

The interiors get red Alcantara upholstery and black leather inserts around the cabin. The car also features a sports steering wheel with paddle shifters. Other elements of the cabin include an infotainment system with Porsche Communication Management (PCM) and navigation. There is also an optional Chrono Package on offer that adds performance display to the PCM functions, which helps in recording, displaying and evaluating track times.
