Vehicles and methods for controlling internal combustion engine rotational speeds are disclosed. Vehicles described herein include an internal combustion engine having a crankshaft and a plurality of drive wheels mechanically coupled to the crankshaft of the internal combustion engine. Embodiments described herein determine a target wheel torque, determine a base increase rate of engine rotational speed, increase an engine rotational speed of the internal combustion engine based on the base increase rate of engine rotational speed, determine an estimated wheel torque, determine an updated increase rate of engine rotational speed based on the target wheel torque and the estimated wheel torque, and increase the engine rotational speed of the internal combustion engine based on the updated increase rate of engine rotational speed.
