I'm not planning on getting a 997TT.
Unless fortune smiles on me and a pile of cash appears out of nowhere, then I can't afford to take the depreciation knock.
If I was going to get one, I would wait for the 997 X50 option. The point of the turbo is power, so you might as well get as much as possible.
The priority for Porsche is to launch the turbo, then the GT3, then I guess a GT2.
The X50 is attractive since it makes money for them, but it causes problems for the GT2, since people just tend to look at the power output and keeping the GT2 far enough ahead is difficult.
997TT 475 bhp, 997TT X50 510-520?bhp, 997 GT2 550 bhp?
Then do a refresh after 3 years, up the power of the 997TT to 500 and you'll see that the GT2 is going to end up at around 600.
This is a lot for a 2wd rwd car with no traction control. You are asking a lot of the rear tyres and the average buyers abilities. (I know the CGT had that much, but on a relatively low revving turbo car, you are going to need 750Nm of torque or so to get that. While some people have upgraded 996TT's to get that, the factory has to consider the bad publicity if people start crashing them.)
My view is that they should not worry about power, but focus on lightness.
I would give the GT2 the same power as the X50 car, but have the unibal suspension, GT3RS front suspension, carbon bonnet and boot, composite wings and doors, and make it lightweight, not 1500kg, but 1400 or less.
The problem is whether enough people will buy it.
The timing of the X50 is not clear. It could be a year or so after launch.
It is possible they will follow the more approach of the other cars and have a turbo S instead, which is perhaps more likely. However, on the 996 this was used for the last year of supply only.
The plan is to keep my 996TT for the longhaul. I do 300+ miles per week.
The idea was to stop changing cars all the time, buy something that met my performance needs and stop trading up. I shouldn't have bothered with the C4S first, since I lost some money on that, but I though it would be enough. Oh well. However, the 996TT with the X50 is enough -
I reckon over 10 years, then the price is not so daft. Somewhere after 150K miles I guess I will need some engine overhaul, and perhaps a new gearbox, then I'll drive it for another 150K miles. I plan to see whether it has some sort of longevity or not.
The only thing that will stop me, is if electronic problems start becoming a major reliability issue.
So far in 27K I have had 2 engine sensors cause problems (one the oil pressure sensor, and one the engine temperatute sensor).
Once it is out of the extended warranty (and I think I will hit 120K miles in 7 years (5.5 years time), then I might tweak it a bit. As things wear out, I might replace them with something newer. So I am interested in the upgrades that the factory are making to the 997, since I reckon quite a few could be fitted to the 996.
I think the new trick centre diff may be a bit to clever for its own good, since electronics are the weakest point on any car.
The viscous coupling on the 996 can't really go wrong.
For the tyre sizes, I reckon the fronts will be wider, since they will need to handle more power, also I believe the weight distribution of the car is slightly more even front/rear, so they may need to do a little more work.
As for the rears, remember they were testing in the snow so the cars would have been running winter tyres.
I think the reporting is not accurate on this one, and at the launch they will be 305's. We'll see.
Of course, if the car can more readily apportion power to all four wheels the rears do not need to be as wide, but then they will be further moving away from a rwd driving feel. If you look at Imprezas and Evos, their tyres are not all that wide. Maybe the fancy diff means they can be narrower.
Tyre size should be what is necessary for the handling, not for show. Also the narrower ones have less rolling resistance and drag. Plus 295's are cheaper, so you don't have to worry about tyre wear.
We only have to wait a few more weeks, then the spec should be out in the open.
I just wonder when the launch will be at Guildford, then I can get a brochure.
