Ahh winter is here... it's alarming for all of us at it gets colder. For some reason the Q's seem to put off more exhaust steam than some other models. We get a lot of these posts every year... I always love it when the guy at the BK drive-thru asks "is your car smoking??"

Function of engine size, as a 4.5 liter burns twice as much fuel per second at idle as a 2.25 liter.Plus the extremely efficient exhaust get the steam out with little back pressure.

Every gallon of fuel burnt emits approx the same in water out the exhaust.
