what mpg were you getting with the bmw? i had a self charging toyota and got on average mid to late 50’s mpg in late svpring to mid autumn. winter it was a bit less what with lights, heating, defrosting etc but was rarely much under 50mpg. worst was about 45. best ive had on short journeys of about 8 miles and really trying was about 90. driving about town you’ll get a bit more than average i found, as long as it wasnt driving at 20 ish all day as battery runs out quite quick.
so thats probably a bit better than a x1.
phevs you may well do a good bit better but have to charge them and they are expensive.
