New to this forum and I've got a question... I'm considering buying and X1 18i but concerned I'll be continually at the petrol station . The BMW blurb says the mpg is 39.2 -40.4...I 'm hoping someone who owns an X1 1.5 petrol can tell me the 'real' mpg.
Typically lab test to real world is 25-30% different for BMW. Low to mid 30’s will be most likely but as above it will depend upon journey type and driving style.
