Classic car 4 (revolution)

I made this project two weeks and three days.
The 9th of May is a day of victory in Second World war and a day of revolution in "Principia".
I have created the mix of Nissan GT-R PROTO (body) and Subary WR-X 2004 (Engine)
It has one biggest surprise:
I have made the best automatically transmission, which somebody ever created and good Sound effects of engine.

Gearbox consists from 8 gears, which can be tune, and R.
Transmission can shift gears like up, like down WITHOUT BUGS!
Car's Max speed - 90.91 (R - 11.21).
If speed > 0.2 then auto automatically stops lowly (simulator of aerodinamics).
The car has only one bug:
If R - off and speed < 0 then aerodinamics - on and car's speed increases (must decrease).
Simple interface and easy control.
Enjoy driving!
