Thread: Mpg help please?

    I win (or lose).
    I've been consistently 11-12mpg since calling the B5 S4 into daily action. City driving is what kills it.
    My commute to work is only 8km, so it doesn't feeeel that bad on fuel.

    Smiles per gallon is through the roof though

    Just in case someone needs a simple online mpg calculator (imperial)...

    https://www.mpg-calculator.co.uk/

    We're getting about 39-40 mpg mixed driving with the Cactus (1.2 litre, 3-cylinder petrol), it's not exactly fast but nippy enough. Definitely more show than go!

    Disappointing alright, although that was US gallons.
    I guess I spend the first 5 minutes in traffic while the car warms up while running rich. The remaining 7-8 minutes of the commute is spent giving it a few shots of welly in 2nd & 3rd.
    On the highway it is relatively normal if you don't play.

    Just checked my math.
    55L ($70) to fill, which gets me 260-270km before I get nervous and fill it again.
    That's 12 Imperial Gallons for a 164mile smile, or 13.66MPG. A miser.

    Or 42c per mile/ 26c per KM for those that are the type to look at people's tax discs and say "Jayzis laaad"


    Going to look at a replacement tomorrow morning, which is arguably (factually) even WORSE on petrol.

    Back when I used to drive a nice tidy mk6 Golf tdi as a daily , I explained how the tax and mpg of my M5 was actually good value, on another forum I used to frequent.
    Some of you may have seen this before.

    "
    Give that man a medal.
    On the tax issue, man maths explains how it's better value than my diesel Mk6.
    Mk6, 2.0, 140 bhp, €270 per year.
    M5, 5.0, 400 bhp, €1809 per year.

    1809/270 = 6.7
    So the M5 is less than 7 times more expensive to tax.

    Yet it has 2.5 times the engine size ( 5.0/2.0),
    It has 2.86 times the bhp (400/140)

    2.5 x 2.86 = 7.14. So it's over 7 times better, yet costs less than 7 times as much to tax.
    Great value.


    Mpg.
    Golf cruising will do 60 mpg with4 cylinders.
    M5 cruising will do 30mpg with 8.
    60x4 = 30x8 = 240

    So man maths means that the m5 is as fuel friendly as the Golf.

    M5 makes me smile 10 times more

    So it's actually 10 times better on mpg.

    Plus the m5 is appreciating in value as the Mk6 is DE-preciating.



    Basic arithmetic really."

    For a 1.8kompressor E class I've been getting 36mpg on a trip such as Dublin to Donegal driving with manners but as low as 25mpg pottering about on short runs.
    I've recently joined the Hybrid brigade and am loving it. 55mpg in an old Prius, not what you'd call an exciting drive but it has appeal in some aspects and I really enjoy it. Can a man be banished for saying such?
