mechanical engineering Does an electric vehicle going

Vehicles will usually only add enough fuel to keep the engine turning at idle speed if necessary but when rolling downhill they can cut fuel flow completely In the case of a combustion engine the break even grade is a bit steeper however since the vehicle must also overcome the un fueled braking effect due to engine compression $endgroup$
