There is something called block heater if it is -38C.
I think modern cars now the computer will adjust the behavior of the engine until optimal operating temperature is reached.
If you have a OBDII reader, you can see how it happens. In winter, it takes much much longer for the car to reach optimal operating temperature. The engine will rev higher in idleing and gas consumption will increase even at constant cruise speed.
Therefore, I think the best is to warm your car for a few min. Then slowly drive it around until the temperature gauge reaches "normal" temperature.
