Power at Driving Wheels (only in professional mode)

This calculation shows the driving wheel power at different speeds. Note that this is the power at wheels (after being reduced with driveline losses) and not the engine power. This is the power that is left to move the vehicle forward.

How to use the Power at Driving Wheels graph:

1. The additional lines 80, 90 and 100% are shown, where 100% corresponds to the highest driving wheel power that can be achieved.

2. The grades lines shows the minimum power that is needed to move the vehicle at constant speed.
   Under Calculations>>Options you can set different grades. Default values, read in graph from right to left, is [ 0 2 4 6 8 ].

Example

With 0 % incline 195 kW is needed to move the vehicle at 125 Km/h.

To move the vehicle at 130 Km/h ,220 kW is needed but there is only access to 100 kW.

The power at driving wheel is shown for every gear. The 100% is highest power that can be achieved. Different gears have different driveline losses.
