Claim One:
1. A vehicle system, comprising: a vehicle including a motive torque source; a transmission coupled to the motive torque source; and a controller in the vehicle, the controller including executable instructions stored in non-transitory memory, wherein the controller is configured to: sense a vehicle speed; provide a torque command to the motive torque source responsive to an output of an adaptive nonlinear model predictive cruise control routine, the torque command determined based on a shape of a vehicle fuel consumption model; and operate the motive torque source to output a powertrain torque, the powertrain torque constrained below a powertrain torque threshold, where the transmission downshifts responsive to the powertrain torque equal to or greater than the powertrain torque threshold at the sensed vehicle speed.
