The spreadsheet linked here can be used to calculate how much power a Gen 3 Magna / Verada needs to achieve any given speed and /or go up hills of a given gradient.

If you want a bit of amusement, and want to see how much power you would need to reach Bugatti Veyron speeds, type "400" in the speed box.

The Gradient is the vertical rise compared to horizontal distance, expressed as a percentage. So, for example, a 100% gradient is a 45 degree slope (equal vertical and horizontal).

Ok, that's pretty cool. It's interesting to know how little power (in comparison) is required to overcome rolling resistance. Have you thought about working a torque formula in there?

Power is Torque times Revs, so torque could be derived from the power, but at what revs? These would depend on the gear being used at any given time. You could simply use the formula

Power (kW) x 9549 = Torque (Nm) x RPM
