My simple brain can't figure this out but why do the figures in the main advert not match any in the lower part official figures for the 3 series xDrive?
Is it a mistake or some form of clever advertising?
No your right, 57.6 and 58.9 are different numbers, however as it doesn't show dangerous driving like the GT86 advert its unlikely the ASA will care
*EDIT*
Working the numbers out I reckon its down to the margin of error for converting between miles/gallon and litres/100km, they have done it twice and got two diff figures due to all the decimals/rounding etc that can take place during the calc.
Of course why they didn't just C&P the first figure they got...
The CO2 is also out, 125g/km in the main and the lowest is 128g/km in the official figures.
EDIT: Just been looking on their website and it looks like the CO2 figures may be auto/manual gearbox related, can't see why the MPG are different though.
I think that's dropping/rounding decimals too though, its quite funny what different results you can get from the same equation just by doing it slightly differently, but I think this is why their figures don't match.
According to Google itself 4.9 L/100KM = 57.6492 MPG (imperial) which ties in with the footnote.
