An engine start control system includes a starter and a motor generator capable of starting an engine. The engine start control system further includes a controller that determines the rotational resistance of the crankshaft based on cooling water temperature of the engine or viscosity of the engine oil, and then selects the starting mode of the engine by a starter motor and a motor generator based on the determination. Consequently, the startability of the engine is improved according to the state of the vehicle.
