BMW is an upmarket brand, so servicing costs for the X1 will be higher than some its more mainstream rivals. Depreciation has been also a tad more severe than some direct rivals, such as the Audi Q3 and Range Rover Evoque, so it’s worth factoring this in.

The X1 xDrive25e is the latest addition to the range and looks very promising indeed. This is the new plug-in hybrid (PHEV) version of the X1, which massively broadens the appeal of the range. Visually the only difference is a flap on the nearside front wing to cover the charging port. Official fuel consumption and CO2 figures hint at this being supremely economical and swift with an official fuel consumption figure of 157mpg and a CO2 output of 41g/km. We've yet to drive this one, and will report back when we do.

Out of the rest, if you want X1 with the best fuel consumption, the entry level SE-spec sDrive18d (with six-speed manual gearbox) unsurprisingly wins out, returning up to a claimed 54.3-56.5mpg under the newer WLTP testing method. At the other end of the scale is the xDrive20i in Sport, xLine and M Sport trims, with a claimed average figure of up to 36.7-38.7mpg.

In terms of CO2 emissions, the manual transmission-equipped sDrive18d performs best at 113g/km, while the worst-performing petrol is the automatic-only xDrive20i at 143g/km. Fitting larger alloy wheels will worsen both of thise figures to 115 and 146g/km of CO2, respectively.

Note that models sold between the Mk2 X1's launch in 2015 and its 2020 facelift were badged the same, but had inferior fuel efficiency and emissions figures - you can check those out in the specifications section.

Reliability isn't the X1's strongest suit

  • Patchy reliability record doesn't impress
  • Multiple recalls on first- and second-generation models
  • Double check all issues have been checked if buying used

BMW in general has a solid reliability record, yet, unfortunately, it doesn’t seem to have transferred to the X1. The first-generation model was the subject of four different recalls, while the current generation model has managed to better this with a total of seven thus far. 

With this in mind, it’s worth absolutely double checking that said recalls have been addressed if you’re buying a secondhand BMW X1. There's no justifiable reason for it not being done as it won't cost the owner anything - any BMW dealer will be able to confirm whether or not the work's been done.
