4.2 engines
now, when i bought my 2003 audi a6 4.2, the guy told me, (which was not at an audi dealership) that when the car starts cruising in 5th gear, 2 or 4 of the cylinders shut off to save gas.
I went to my local audi dealership and I asked a rep there, he wasn't too sure.
Now I may be ignorant, but if anybody can clarify this for me, that would be great.
Thanks

Don't think the v8 in our car has it though, as fuel economy on a luxury v8 is really far down the list.

A lot of the newer V8's have this kind of feature, most dodges for sure, they call it multi displacement system or something like that, basically switching off 4 of the 8 cylinders when cruising on the highway below a certain rpm range.

I didn't think so myself, just wanted to confirm, wishful thinking, lol
