BMW X4 review - MPG, CO2 and running costs
Choose a diesel-engined X4 and you should see relatively decent economy, although insurance costs could prove to be expensive
Like most big premium SUVs, the BMW X4 won’t be especially cheap to run – but fuel economy and emissions are good for this class. The xDrive20d model is capable of up to 49.6mpg when driven with restraint, but can still deliver brisk performance, while the 3.0-litre diesel can manage a claimed maximum of 45.6mpg. Emissions are quoted at 150g/km for the xDrive20d on its smallest available wheels, while the xDrive30d emits upwards of 163g/km of CO2. The M40d returns an average of 41.5mpg and emits from 179g/km according to WLTP rules.
The M40i model is inevitably thirsty, with an official combined figure of up to 31.4mpg. The hotter X4 M Competition is the least efficient car in the range, returning around 26mpg and emitting from 244g/km of CO2.
The X4 xDrive20d M Sport model is in group 33 for insurance which is broadly in line with its key rivals, but will result in above average premiums for most drivers and is also higher than the equivalent X3 model. The rest of the X4 range is rated between group 41 for the xDrive30d models, group 42 for the M40i and group 43 for the M40d, so insurance premiums will be a significant ongoing cost if you choose the higher-output models.
BMWs typically hold their value well compared to premium rivals, and the X4 is no exception, with an average of 55 per cent of its original value retained over a three-year/36,000-mile ownership period.
