about the tourqe thats the all deal, if you add more tourqe the car will be faster if you decrease the tourqe the car will be slower...
in real life there is indirect connection between engine RPM to the wheel RPM... first gear is more power less speed and 5th gear is less power more speed.



I can't quite follow you. What you refer to as power is effectively torque. In a car simulation we don't care about the power available from the engine, but the power delivered to the drivetrain (behind the gear box). Since the engine's power there is used to rotate the wheels you can ignore the engine power and only look at the torque at this point.

The first gear should provide high torque but only low speed, and the fifth gear should offer a high max. speed but very little torque.
Torque does _not_ in and of itself determine speed, it determines how much resistance the wheels can overcome. What determines speed in GameStudio is the speed value you set for that particular motor. Whether this desired speed can actually be achieved depends on the car's mass, friction, dampening and how much torque you allow to be applied.

What happens if you change your script (gear definitions) so that the torque values get lower and not higher as they are now ?
