problem with speeds and gradients

HI, I am facing a problem using newton vehicle. I have real parameters for heavy truck. When I applied the same torque as given by the manufacturer, maximum speeds are no where near the expected. At the same time my vehicle climbs up any gradient, if I set the mass to a lower value. Main problem, I observed here is with the rolling resistance, I mean, the vehicle comes to a constant speed at a particular torque, but this torque is increasing from gear to gear(with the vehicle speed). The variation so much, which is not expected. How can I avoid this? Friction values are not effecting my speed. very low friction values reduce the speed too much. but beyond certain value, its not effecting at all. Any Idea????

Are you handling damping by yourself or maybe the default damping system is slowing things down?
