Porsche pumps up the 911 GT3 with RS version

Published on August 20th, 2009

As if the Porsche 911 GT3 wasn’t mind-bogglingly quick enough the boffins at Zuffenhausen have given it the diet and steroid treatment to leave us with another car that we will probably never own but would be willing to trade our souls, mother-in-laws and hot secretary for a spin in it.

The Porsche 911 GT3 RS as it shall be dubbed sees a bump up in ponies, tips the scales slightly lower and for good measure shorter gear ratios. Even the body and suspension components have been upgraded to squeeze out every pony, plume of petrol and air particle from this track assassin.

There’s no replacement for displacement as they say and rightly so the six-cylinder boxer engine has its displacement bumped up to 3.8-litres (up from the previous 3.6-litres) so the tacho needle can reach for the 8,500rpm sky faster.

Power climbs up 15 notches to 450hp over its garden-variety (well in this case anyways) 911 GT3. Considering the engine is not blown its 118hp per litre specific output is one of the highest for a naturally aspirated powerplant.

All those thoroughbred horses find their way to the rear wheels via a proper six-speed manual gearbox with shorter throws for quicker shifts. The best bit is that to fully extract the potential of the engine the gear ratios have been shortened to deliberately concede an even higher potential top track speed.

The engine itself sits on dynamic engine mounts. Dynamic engine mounts function by altering the stiffness and damping effect to suit the driving conditions, thus improving the connection engine and chassis. The end result will have the car ripping tarmac off Sepang International Circuit while providing a decently comfortable ride on the drive back home.

Light-weight is one of the key factors to the performance of the GT3 RS and GT3 for that matter so Porsche have replaced the traditional lead-acid battery with a lithium-ion unit that reduces weight by more than 10kg. Just to put things into perspective, race engineers would kill to just slice 1kg off a race car.

With such power on tap Porsche have upgraded the handling bits as well with a purpose-built PASM suspension setup and a wider front and rear track with extra flared arches to cover the wheels.

Speaking of which, the GT3 RS sports some nice kicks directional duties handled by 19×8 wheels and 19×12 wheels waving the tractional flag. Rubber sizes read 245/35 ZR19 for the bow and 325/30 ZR19 for the stern.

Undeniably the GT3 RS is the wildest looking Porsche yet with its slammed ride height, larger carbon-fibre wing and titanium exhaust system.

With a list price of just USD132,800 for all that driving pleasure, it looks like a steal compared to yesterday’s Devon GTX although that’s a totally different ballgame in itself.

Lookout for the GT3 RS at the Frankfurt Motor Show next month.
