Vehicles such as a combustion engine, electric, and/or hybrid electric vehicles and methods of operation, which include controller(s) configured to respond to cruise control signals, and to generate a route efficiency profile according to instantaneous vehicle performance parameters and environmental conditions. The controller(s) are also modified to adjust a vehicle cruise speed according to the signal and profile, to enable reaching at least one designated destination in a minimum time, and whereby vehicle range is extended to the destination, while one or more reserve energy limits of battery power and fuel are maintained. The controller(s) are also adapted to detect instantaneous feedback signals that include the performance parameters and environmental conditions, and to generate error signals according to an actual vehicle watt-hour per mile efficiency and the route efficiency profile. The controller(s) adjust the cruise speed adaptively according to the error signal, such that error signal magnitude is reduced.
