    Just another note on the rolling road tests, I've read somewhere in the past that they even push the pads further in the calipers to stop any additional friction

    Hi, have a 2009 CDI 451 and over the years the miles I get out of blue has improved. on a tank ish I get around 400 miles, with about 4 litres to spare. However I did a long drive to Scotland from the South East and got 520 miles before I chickened out and filled up, could have been a litre or two left.

    I have been watching mpg for my 1.0 mhd for the past few weeks

    I travel around 100miles a day, on a mixture of motorway, dual carriageways and A roads, I travel off peak time, my mpg has varied from 48-68mpg, if I cruise along at 65-70mph, then my mpg tends to be nearer high 40's mpg, last week I drove like Miss Daisy and didnt go faster than 55mph and got 68.13mpg

    Read somewhere on internet that if buying a car, check Government rolling road figures and take off at least 5 MPG to get the true road figure.

    The above and reading forums like this, made me decide at the time on buying a 451 Cdi (around 80 MPG) rather than a 451 petrol (around 40+ MPG), which is a massive difference.

    I have been happy with the Cdi, and it quieter that you think, though I have put two rolls of car sound insulation in the boot, over the engine compartment LOL!

    I get high 40s mpg from both my Roadster & 451 Passion 84bhp on a commute of 45 miles round trip, mostly town driving but not peak times. Neither are driven for economy

    I'm consistently getting 70+MPG. 2010 CDI Passion fitted with the wider Pulse wheels.
    A roads and dual carriageways are kept to 1800-2000RPM.
    Motorways 2500-2700RPM.
    It's not all about the speed
    Haz a seedy eye!

    Correct, the Cdi is nippy enough, and mine can get from 0 to 60 MPH eventually

    Recently changed from an 03 reg 700cc Smarty to an 09 Passion MHD Auto.
    Sure have seen a drop in MPG. In the last 500 miles of 'Not heavy footed' mixed driving
    the Passion is doing 43mpg. Not impressed with that. I always switch OFF the EKO by the way.
    Somewhat better than my main vehicle a Vauxhall Amara Diesel that struggles to average 28-30mpg.

    Sounds about right, I get 10mpg less from the 451's than my 450 but the 453 does get the same as the 450
