997 GT3 - I thought it would be faster..

[steved]

Interesting to read the Sport Auto Supertest of the new GT3, and perhaps it might silence those people that whined on about the CSL being quick only because of its Cup tyres. The 997GT3 (also with cup tyres) was 'only' 2 seconds quicker around the 'ring.

Nurburgring:

With a lap time of 7:48 mins the new 997 GT3 is just one second off the time set with the 996 GT3 RS before. The best time eas achieved not with PASM "Sport" setting hut the basic setup as the damers were not that hard and the car better to control. The PASM "Sport" setting is only suitable for flat tracks like the Hockenheimring.

Hockenheim:

here the new 997 GT3 was 1.5 secs. faster than its 2 years old predeccessor 996 GT3 and even 0.1 secs. faster than the sportier 996 GT3 RS. Tthis due to the progress made in driving dnymamics. The change from light understeer to light oversteer is easy to control, the 996 GT3 offers best handling.

0-200-0 kmh in 18.6 secs

it is hard to find the right grip. it took a dozen of attemps to get used to it and to achive the best time as there is no launch control and the driver has to find the right balance between the clutch and the throttle. The clutch even stand all these attempts.
The shifter of the 997 GT3 is not as easy to handle as of the Carrera S even though the gear shifts are exact and clear.
The cewramic disk brakes allows better breaking and also lasts longer than the standard brakes.

aerodynamic:

the 997 GT is well ballanced with no up- and no downforce at 200 km/h, so the aerodymanic has no influence to the handling at any speed, it si neutral.
Even though the aero package with the front apron and the rear wing, the drag coeffcient is pretty low: Cd = 0.29.


max. lateral acceleration: 1.3g

the new Michelin Cup Sport tyres, not the same as for the M3 CSL at that time, have a different geometry and offer a better wet handling. 1.3 g is not the max. for s supersports car but pretty much enough.
The 997 GT3 is at the same level as the Ford GT, Gallardo and 996 GT3 RS

specs:

3.6-litres flat-6 eingine
415 PS at 7600 rpm
405 Nm at 5500 rpm

0-200 km/h in 13.9 secs.
Vmax = 310 km/h

slalom 18m: 71.8 km/h
slalom 36m: 141 km/h, better than the Koenigsegg CCR (138 km/h) and the Zonda F (137 km/h)
evasion test 110m: 158 km/h, same as the CCR, 1 km/h less than the Zonda F and 1 km/h quicker than the M3 CSL or CGT

wet handling:

best time for the 997 GT3, even 0.3 secs. quicker than the Audi RS4 at the wet hnadling track thaksn to the new Michelin Pilot Cup Sport tyres

verdict:

the 997 GT3 is true sports car and takes you into the spell pull. The 3.6-litres flat-6 engine shows its racing heritage. Even though the pursitc 997 GT3 is an every day racer for the experienced driver, not that challenging but less comfortable.

the 997 GT3 is a perfect sports car, it scores 77 pts., more than the CRR (77) and the Zonda F (74), both are more extreme.

the 997 GT3 has set two new records in the sport auto Supertest:
36m slalom and wet handling!

That is impressive stuff Steve - no doubt Angus will fly the M3 CSL flag - and with current secondhand CSL values makes it a fantastic track proposition for the money. Bargain 'springs' to mind

It just goes to show that you need a considerable increase in performance/capability to post a much improved 'Ring time, which makes the few cars that have reached sub-7 min 30 seem mighty.

In the CSLs favour its 'Ring time demonstrates how impressively neutral and stable its chassis is. From a pure performance standpoint the 997GT3 laps Hockenheim Ring just over 2 seconds faster than a CSL (hence quite a bit quicker), although as Angus would rightly claim that difference could be substantially clawed back if the CSL was fitted with a wider front tyre and a few more degrees of negative camber. Still, it does make the CSL seem even more of a bargain (£50k less than a new 997GT3...)

Could the same not be siad of the GT3 though? i.e. changing geometry etc to suit the track only?

Wow... a rwd 911 on cup tyres quicker in the wet than a Quattro uber-Audi...!
