Vehicle Speed calculation

By using Prescribed method you will be able to find vehicle speed at any Gear 
you will need to have these inputs to perform the calculation:

 1) Engine RPM (N)=2500
2) Tyre revolution/Km (M)=398
3) Total reduction of power train (Rg)=14.3856:1

 vehicle Speed formula is given by
V =Vehicle Speed in Km/hr.

 V= (N X 60) / ( M x Rg)
  =(2500 x 60)/(398 x 14.38)
  =26.19 Kmph

Calculate Tractive Effort at wheels-TE Inputs Required Torque at Wheels = 32607 N-m Tyre SLR = 0.4 meters Tractive effort (N) =  Torque at Wheels  /  Tyre SLR = 32607/0.40 =81518.4 N Related Link https://autocal1.blogspot.com/2020/06/calculating-torque-at-wheels-inputs.html

Finding Engine torque value You must have Engine Torque and power curve data sheet, You can get this from engine manufacturer or from their website. Engine torque and power is mapped against Engine RPM. A typical example can be seen here. Torque curve sample Image

Power to weight ratio : PWR Power-to-weight ratio  is a measurement of actual performance of any engine or  power  source. It is also used as a measurement of performance of a vehicle as a whole, with the engine's  power  output being divided by the  weight  (or mass) of the vehicle, to give a metric that is independent of the vehicle's size. It is defined as per requirement of vehicle performance. It can be defined in terms of (in SI Units) HP/Tonne Kw/Tonne Kw/Kg Example Engine Power= 350 Hp Vehicle GVW=18000 Kg= 18 Tonne PWR= HP/Tonne 350/18= 19.5 Article Contribution by Sandeep Bhasme.
