    Yeah....there's definitely something wrong here! That's the kind of figures I was expecting.
    Last long motorway run I was just cruising at 70 for entire journey...but as I said previously, didn't even hit 49 mpg. Got the fuel pipe recall to sort out soon, so I reckon the garage will have a few other things to look at
    Just noticed that I'm losing dab signal when rear demister is switched on.
    I may have bought a pup .

    It is disappointing when you buy a new or nearly new car and things aren’t right - despite the warranty. Mine went back in as soon as I had it as the keyless entry stopped working (I got it back with a dent in the door - which was sorted). It’s booked in again for a dash warning about parking sensors and for fitting the second rear light cluster as the both original and replacement suffer from condensation! Trouble is it’s a great looking car and drives very well compared to the previous model in my opinion. Just need to “bond” with it at some point!

    Mine (euro 6) wont do anything like these figures no matter how steady I go best I can get is 46 if sticking to 55/56 on motorway might be due to it being Automatic but I gave up long time ago believing what sales literature says.

    Yep the figures on that web site for the 2.0 Turbo D 170 Automatic "real MPG" are are near to what I can achieve if i'm careful but I do have to be careful, The 50 mile motorway journey last night with speeds 75 or less is showing 41 MPG, most of time its around 36/37 when keeping up with traffic.

    A stupid question, as I live in an area where you measure consumption by L/100km (litres per 100 kilometres), but do you use MPG (US), or MPG (imperial) as a consumption measurement unit? There seems to be quite a difference if Spritmonitor.de is to be trusted, which I use for consumption logging.

    As a comparison, my Kia Optima (1.7 automatic), which is roughly a same sized and weighted car than Grand Sport, goes an average 42 MPG (US), or 50+ MPG (imp), on a 47 000 km (29 000 miles) record period. Translated from 5,58 L/100 km. I feel it's quite decent for a car this size, but not even close what the manufacturer has reported as a NEDC consumption when I bought it.

    In the Uk most people use MPG ("G" being imperial Gallon), I'v never got my head round a why a Gallon in UK is not the same as a gallon in the US.

    This is a good idea.....thanks for reminding me of the difference. Unfortunately, the car only has 2 options in the menu system...Imperial and Metric. Imperial has been selected.
    Reading this forum has made me think though that it's a good idea to (not regularly, but every now and then) disconnect the battery for a while to reset everything fully. I think i'll give this a go over the weekend. The car was never properly reset when i purchased it from the Network Q garage. Still had previous owners phones etc in the system.
    Sometimes turning it off and back on again works wonders
