The Worlds Fastest Jaffa
In this years Targa Tasmania Jim Richards is campaigning the recently released 2007 Porsche 911 GT3 RS so it seems fitting to have a closer look at this amazing machine.
Note that the GT3 RS uses the wider Carrera 4 body but weighs less than the standard narrow bodied GT3ï¿½
The GT3 RS is the 911 for puristsï¿½ with a penchant for the raceï¿½ track. The â€˜RSâ€™ moniker harkens back to 1972 and the legendary Carrera RS 2.7 which (if you can find one) is now a serious collectors car with a serious collectors price. â€˜RSâ€™ stands for Renn Speed which translated means Racing Speed and itâ€™s a fairly apt description.
Traditionally, the RS Porsches have been lightened and tweaked versions of their standard specification donor model. Not that your average GT3 should ever be considered standard. I guess what it all means is that if the current Porsche 911 GT3 isnâ€™t hard-core enough for you then the RS version is going to be more your style.
The GT3 RS is powered the 3.6-litre flat six (not the 3.8-litre unit) from the 911 range and has been tuned to produce 305Kw and 405Nm. To put that in perspective the power figure is virtually line ball with the current HSV 6.0 LS2 engine. Comparing these two engines is rather pointless but it does give you some idea just how highly strung the Porsche unit is. Maximum power for the GT3 RS is reached at 7600rpm but the engine will happily rev to itâ€™s redline of 8400rpm.
It should be noted that the â€˜normalâ€™ GT3 model uses exactly the same engine with the same output. What going RS buys you is close-ratio six-speed transmission with a single-mass flywheel and a 20kg lower vehicle mass.
Subtle changes that allow the RS to achieve a 0-100km/h time of 4.2 seconds which is 1/10th faster than the â€˜normalâ€™ GT3. Maximum speed is 310km/h.
If you don't like the orange you canï¿½ get a green one...ï¿½
The interesting thing is that the GT3 RS achieves this lighter weight despite the fact that it uses the wider (and heavier) Carrera 4 models body. This means it is 44mm wider at the rear than the â€˜normalâ€™ GT3. The wider track at the rear provides improved directional stability and obviously provides grip and handling benefits in a racing environment.
All up the GT3 RS weighs 1375kg and the weight-saving was achieved through the use of exotic and lightweight materials for various items. The adjustable rear wing is made from Carbon Fibre, the rear window is lightweight plastic as is the rear engine cover.
Lightweight racing bucket seats made from Carbon fibre continue the light weight theme into the interior. A roll-cage is standard as is a fire extinguisher and six-point racing harness for the driver.
The 2007 Porsche 911 GT3 RS is available in Arctic Black or Silver. Alternatively for those with a fondness for the 70â€™s green and orange are available as an option. It is expected to be on sale in Australia before the end of June and will cost $299,000.
It should be interesting to see how Jim Richards fairsï¿½ in this years Targa Tasmania in his GT3 RS. I suspect that if the roads are dry he will be hard to beat but if it rainsâ€¦a rapid rear-engined rear-wheel drive could prove a handful even one with a wider track.
