I was able to tour the Subaru plant last Friday morning. I asked about 5 different employees about the upcoming STI. They said it is top secret until the unveiling in Tokyo next month. The only thing they could confirm is that it will be a hatchback only. They said it had to be a hatchback in order to be competitive in WRC.
It was pretty neat seeing how a car goes from bare metal to finished product. There are a ton of people involved in the process. When I pictured the factory I pictured robots doing all the work, but this isn't the case. They have hundrends of employess putting on trim, hand sanding, and testing the final product. Each car is put on a dyno and the guy runs it up to over 100MPH. All that break-in stuff has to be no sense b/c they totally reamed each car.
After the tour I was able to drive an 08 WRX wagon. The power band felt much smoother than my 05, and the ride was a lot better too. I'm assuming the powerband is smoother due to the new turbo. There was no rush of power when the turbo kicked on.
The shifter action and clutch take up was still pretty sloppy just like my 05. I thought they would have fixed this but they didn't. Overall, I think it's a good car for the masses, not the enthusiast.
