    Wonder what other W220 S500's get on a motorway cruise. I am getting around 28mpg with cruise control (Distronic actually) on. Car is 11 years old but has been well maintained. I think that is pretty reasonable.

    Is this good, bad or average?

    28 mpg sounds pretty good (my 14 year old SL500 is similar). Depends a bit on what speed you're cruising at though :)

    ...that and anticipating the traffic so as to avoid accelerating and braking where possible.

    I wish.
    All these figures seem pretty good when you consider the size of these engines - work colleague was telling me about a friend of his who has a 6.6 V8 Firebird Transam from the 70s and he gets at best, 9mpg and usually 6mpg.

    Old Yank engines are notoriously inefficient (cheap petrol).

    The V8 M-Bs are pretty good when cruising. Stop/start is a different matter (even my SL weighs in at almost 2 tonnes).

    Yep, one of THOSE !!!
    I've clipped 31 mpg on a run in my S500 before.

    Generally 27-29 on a decent run, 25 on the short motorway/urban run to work, 16-18 in and around town and single digits if having a 'heavy foot moment !

    S classes 220 are very very slippery, hence the high MPGs from the petrols.
