Here it is, the new 2016 Porsche 911 GT3 RS. Moving onto the 991-generation 911, Stuttgart’s latest lightweight track car makes its world debut at the 2015 Geneva Motor Show.

Using the bog-standard GT3 as a base, the RS tacks on a wider body from the Turbo, deeper front splitter, side skirts and rear valence, downforce-inducing front fender vents, extra air outlets on the carbon fibre engine lid and a large adjustable rear wing. Twin creases running down the magnesium roof and carbon fibre bonnet pay homage to similar indent seen on air-cooled 911’s.

Inside, the RS is fitted with carbon front seats from the 918 Spyder, a six-point driver’s safety harness, a bolt-on rear roll cage, preparation for a battery master switch along with a fire extinguisher. A Sport Chrono Package is optional, and aside from an onboard lap timer, also includes a Porsche Track Precision smartphone app that logs vehicle data and times laps via GPS.

The use of lighter materials and a stripped-out interior mean that despite the wider body, the GT3 RS weighs just 1,420 kg, 10 kg less than the standard GT3.

At the rear, the GT3’s direct-injected, naturally-aspirated flat-six engine has been bored out from 3.8 litres to 4.0 litres, enabling it to produce 500 PS at a stratospheric 8,250 rpm and 460 Nm at 6,250 rpm. With power sent to the rear wheels, the RS launches from 0-100 km/h in just 3.3 seconds, passes 200 km/h in 10.9 seconds, and hits a top speed of 310 km/h.

Like the regular GT3 (and unlike the manual-only Cayman GT4), the RS is fitted exclusively with a specially-developed seven-speed PDK dual-clutch transmission. As on the lesser model, the ‘box comes with a “paddle neutral” function that opens the two clutches when both paddles are pulled, then closes them at “lightning speed” when released to perform a “clutch kick” that alters the car’s cornering stance.

Peer beneath the metal and you’ll find electromechanical power steering, active rear-wheel steering and a fully-variable limited-slip differential with Porsche Torque Vectoring Plus as on the GT3, but with a wider front and rear track for better roll stability. The RS is also fitted with the widest tyres fitted on any 911 – 265/30 on 20-inch wheels at the front, and 325/30 on 21-inch wheels at the rear.

So competent are the tweaks that the new 2016 Porsche 911 GT3 RS is claimed to lap the Nürburgring Nordschleife in 7 minutes 20 seconds, quicker even than the 7 minutes 28 seconds set by the 2003 Carrera GT. It will go on sale in a few months, with prices starting from €181,690 (RM738,200).
