Analysed: Porsche GT2 RS

The powerful GT2 was defeated 2 years ago when the GTR beat its Nurburgring lap time by an astounding 5 seconds. However, Porshe’s commitment to Intelligent Engineering and 60 years of race car development has produced the lighter, more powerful 911 GT2 RS. Sold as a track car although fit for the streets, it has a limited availability of just 500 units and a price-tag that can fetch 3 Godzillas. Despite standing at the forefront of engineering sophistication alongside the Audi R8 GT, Porshe repeatedly compared the GT2 RS with the Nissan GTR that once brought it down – to reinstate the pride it once had at Nurburgring.

All that power
The GT2 RS achieved an 8 second faster lap-time than the Nissan GTR recently at the same Nurburgring circuit, and 13s more than its predecessor GT2. Much of the achievement can be attributed to the vast improvements, most notably the GT2 RS’s intake systems and power transmission. Yet in its bid to prove itself, all the increased horsepower (620) has only made itself look more American than German. (The GT2 was already churning about 25HP more than the Godzilla). It boasts itself in achieving an impressive power to weight ratio of just 2.21kg/HP, which is significantly better than Godzilla’s 3.6kg/HP or any other agile sports car on the planet (maybe not… read below)

Not waterproof yet
Here’s something that the GT2 RS warned of which probably no other supercar did: Do not race in wet terrain. The GT2 RS is just too light and too powerful, despite being able to hold lateral forces of 1.1G without losing traction. Wide 19-inch wheels with a lower thread profile and a central locking device offer better racing dynamics and faster wheel changes due to lower rotating masses, very much like the GTR, while preserving stability. Nevertheless, the very design also makes aquaplaning a real threat. Best to wait for the GTR to wipe the track dry.

Acceleration like no other
Surely, there’s no way a Porshe could accomplish enough acceleration to do a wheelie or drag race a Viper. However throw in a few slaloms and chicanes, and there’s nothing that could go faster than this slick flick. That’s how the GT2 RS shaved off 8 seconds from the GTR, by keeping tight at the corners.

For a start, the 3.6 liter six-cylinder boxer engine features two variable turbine geometry turbochargers. Unlike conventional turbos, incoming exhaust gas is directed electronically to the VTGs through adjustable guided vanes. By changing the angle of these vanes, the flow speed of exhaust gas can be controlled, and thus the momentum on the turbine can be changed. This essentially means that it can control precisely when the turbo should kick in – even at lower RPMs. With this technology, turbo lag is minimized – perhaps even almost omitted, and the resulting acceleration gains are greatly rewarding on track. As if to make sure that aftermarket turbos performing like VTGs do not simply appear on a V-spec, Porshe engineers went a level further with the expansion intake manifold. Together with the turbo, this intake system ensures that air entering the cylinders is kept cool and dense via the charged air cooler for optimum ignition of the air-fuel mixture for maximum power and improved fuel consumption. You can’t get that sort of air quality with a cold air intake and one of those air cyclone inserts.

Beast turned Beauty
With its price tag and limited supply, driving around in this was already cool enough. Precisely why, the engineers decided that while it’s designed for the track, it would be better off as a status symbol on the roads, and messed up its looks. Here we have the first track car that rolls off the production line – stock rims that are gold plated. As if that wasn’t enough, they fitted daytime LEDs to the front of the car. Why would a track car need daytime LEDs? One reason could be, like the Golf R, the brake air spoiler took up the area in place of the fog lights to direct incoming air to cool its Ceramic Composite Brakes.

Carbon fibre has also found its way on many places on the GT2 RS. The dry carbon fibre bonnet, although is a weight-shaving add-on, serves best to differentiate this from the predecessor GT2 as well as other 911s. There’s more around the car as well, from the grilles to the mirrors, even the spoiler lip and back. Even the front lip (commonly made from PVC for durability) can be changed to CF on request.

Much of the interior retains a sporty posh look, with leather and red Alcantara wrapping the carbon fibre bucket seats and everywhere else with body contact. Roll cages are optional too, this means you don’t have to settle for extra advertising decals with aftermarket ones. The GT2 RS hence stands out as the best looking stock car that is track ready, and we mean seriously ready.

The GT2 is defeated but not out…
While the GT2 RS was made to avenge the GT2, Supercar tuner Switzer Performance took in the defeated GT2 and injected JRZ Racing’s torture-tested setups from the Patron GT3 Cup and Grand-Am Rolex GT series. So much so that the reincarnated Switzer R911S has well over 900HP and enough to keep the GT2 RS far away from hoping to slipstream and slingshot around it. To ensure that the GT2 RS doesn’t kill the R911S at the corners, a Switzer-specific titanium inverted-front-strut, remote-reservoir suspension by JRZ Racing keeps it in check. All that power makes it virtually impossible for any track car to take on the R911S on the straights while MONSTER intercoolers ensure that the engine keeps going. Now that makes the Godzilla look like a house lizard.

Further adding to the RS’s redundancy, the Americans (Ohio-based Switzer) made the GT2 a lot more practical to own for track purposes. All the advantages over the GT2 RS is offered for $46,000 less. And to make matters worse, the GT2 RS’s identity was stolen and duplicated for $6000 less on the R911S Carbon edition. Even each R911S has specific spring and damping rates, adjusted to each client’s track experience and even driving aggression. Seriously now, why do you need the GT2 RS?

The Final Verdict
It’s finally clear why the youtube ad for the GT2 RS features a running “&#@%ING %#&&!!” sign (see video below). It’s what you get when Porshe launches an engineering milestone, only to be laughed at by Supercar tuners. It’s only advantage over its jetpack cousin R911S is the fuel efficiency, which doesn’t even make sense for a track car.
However, Porshe can be assured that its environmental concern will be much appreciated in Singapore as the GT2 RS has everything needed for this city – Limited Edition status, lean looks and an 11 km/l fuel efficiency rating (Urban mode). Excellent choice to drive around town, retaining the ability to mock Matt black Godzillas without worrying about catching fire like other Stallion or fighter bull. Best of all, there’s no race track to compete.

    I only wished the colors were as dramatic as the GT3 RS. I guess that’s the latter’s trademark.

    Unfortunately so Andre….looks a little raw and unpolished which I think suits the car perfectly.
