@NonNull abstract fun withDownhillEfficiency(downhillEfficiency: Double!): IRouteQuery
Specifies the efficiency of converting potential energy to saved (not consumed) fuel when the vehicle loses elevation (i.e., ChemicalEnergySaved/PotentialEnergyLost). ChemicalEnergySaved is obtained by converting saved (not consumed) fuel to energy using fuelEnergyDensityInMJoulesPerLiter.
downhillEfficiency - Double!:
Return
IRouteQuery: The route query.
