A vehicle engine warm-up apparatus includes a coolant temperature sensor, an intake temperature sensor, an air intake heater, a heating system and a controller. The intake temperature sensor measures a temperature of combustion air entering the engine. The coolant temperature sensor measures a temperature of engine coolant. The air intake heater is configured to heat the combustion air. The controller is operably coupled to the coolant temperature sensor, the intake temperature sensor and the air intake heater. The controller is configured to operate the air intake heater with the vehicle engine running to increase a rate of heating of the coolant by the engine to more rapidly make heat available to the heating system in response to determining that the air intake temperature is below a first temperature threshold and the coolant temperature is below a second temperature threshold.
