Since its 2003 introduction the Porsche 911 GT3 RS has been seen as the ultimate 911 derivative. Stripped bare, harder and sharper, it has always blurred the lines between road car and racer.
Joining this illustrious 911 GT3 RS line is the 991 edition, which is now on-sale in Australia, priced from $387,700 (plus on-road costs). Deliveries are expected from the third quarter of 2015.
Based on the 991-series GT3 the latest 911 GT3 RS retains the PDK dual-clutch transmission, though rumours persist than a manual version could be built if there is sufficient demand.
The new 911 GT3 RS sprints around the traditional Porsche barometer – the Nurburgring Nordschleife – in 7min 20sec, beating even the Carrera GT supercar’s 7min 29sec lap time.
The gains come from ‘extensive’ modifications to drivetrain and aero, along with the traditional 911 GT3 RS weight reduction measures.
Porsche has taken its flat-six to 4 litres capacity, up from the 3.8 of the regular GT3. It produces 368kW, up from the 354kW of the regular GT3, and is backed by 480Nm of torque; some 40Nm improvement. Zero to 100km/h is achieved in 3.3sec, zero to 200 in only 10.9sec.
More focus has been applied to functions such as ‘paddle neutral’, which is likened to dipping the clutch in a manual vehicle, while a pit speed button can be customised to suit circuit requirements.
To give more of an idea of Porsche’s obsessive pursuit of light weight in the 911 GT3 RS, the roof is made of magnesium. Carbon fibre is of course present, used for the engine and luggage compartment lids. This reduces weight by around 10kg against the regular GT3’s 1430kg, with the added benefit of a lower centre of gravity.
While a 10kg saving mightn’t sound much, consider that the 911 GT3 RS body comes from the wider 911 Turbo, and has several aero aids, the reduction becomes significant.
The front spoiler lip works with unique front wheel arch vents, which extend into the upper section of the front wings, combine to significantly increase front-axle downforce; the large rear wing provides same for the rear.
Rear-axle steering and Porsche Torque Vectoring Plus with fully variable rear differential lock are standard fit and wider front and rear tracks add stability.
Inside the 911 GT3 RS incorporates full bucket seats which are based on the carbon versions found in the 918 Spyder. The Club Sport package is standard and includes a bolt-in roll cage, battery master switch preparation, fire extinguisher and ‘separately provided’ six-point harnesses.
Given the breadth of changes over the ‘regular’ GT3 – and its assured exclusivity and collectability – is the $93,600 price differential substantiated? Let us know what you think in the comments, and check out the promo vid here.
