First, it doesn't save fuel.

"Auto" mode sends some power to the rear wheels a little, coming from a full stop, even if no slippage is detected, so it gives that nice "RWD push" feel.

2WD mode seems to "feel" a bit lighter on the engine, but it tends to spin the front wheels on hard take offs, and give that oversteer tendency when turning while accelerating.

So, is there any practical reason to use the car's FWD only mode?
