Claim:
1. A method, comprising: determining, at a controller for an engine, the controller having one or more processors, a desired air-per-cylinder (APC) for the engine based on an engine torque request; determining, at the controller, a volumetric efficiency of the engine for electronic throttle control (ETC) based on the desired APC, an optimal lift for an intake valve of a cylinder of the engine, engine speed, and an actual intake manifold absolute pressure (MAP), wherein the optimal lift for the intake valve is optimized for engine torque response; determining, at the controller, a target MAP based on the volumetric efficiency of the engine for ETC; determining, at the controller, a target lift for the intake valve based on a volumetric efficiency of the engine for variable valve timing (VVT), engine speed, and the actual MAP; and performing, by the controller, coordinated control of ETC and VVT by concurrently:
