My views on what the face-lift TT may bring...
Direct InjectionI think the difference with DI will be too small to notice myself. Yes, 4% extra power would be nice, but will you actually feel that? Plus the 8-15% more fuel economy would be nice too, but frankly that won't make a large dent in my fuel bill and won't exactly save the planet either (not that I buy into 'CO2 = global warming' political bandwagon anyway). I also wouldn't be surprised if Porsche saved DI for the 998. There are a lot of rumours I have read that say the Turbo's engine won't be updated until 998 model.
The re-stylingFor me, Porsche are restyling each component of the car separately these days without looking at the car as a whole. The Turbo and GT2 in particular look like they have been designed by 20 different guys who only come together with their designs at the assembly line. The face-lifted spy-shots look like Porsche has taken this to a whole new level.
LED rear lightsI personally don't see the huge need for LED rear lights myself. OK so they give the person behind you more warning when you brake. But if you break heavily in a Turbo at 70+mph then the person behind you better be a LONG way back anyway for you not to out-break them!
DSG gear-boxI am still not convinced Porsche has addressed the reported issue with a DSG box handling all that power. I think 1st generation in a Turbo is going to be flaky at best. Plus I love changing gears with a manual so DSG wouldn't interest me anyway.
Sports ExhaustPSE as far as I know is not on the agenda for the 997 Turbo, so you are better off going after an after-market exhaust
Heads up displayThis may actually be quite useful to Turbo owners who find themselves having to look more at the road than at the rev counter/speedo. I have hit the rev limiter myself every time I have driven a manual Turbo thus far...
By the time 2009 comes along, you will have only 3 years to wait until the 998 Turbo comes out and surely there will be a bigger technology leap here than going from 997 to 997.5.
So all in all, I would rather spend my money on a Ruf or Cargraphic exhaust + ECU for a 997 Turbo I can get my hands on ASAP.
