Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2018 M240i xDrive.
The 2018 BMW M240i xDrive is a compact executive coupe equipped with all-wheel drive and paired with an eight-speed automatic transmission, offering drivers the practicality of xDrive traction in a two-door sport-oriented package; EPA fuel economy ratings stand at 21 mpg city, 30 mpg highway, and 24 mpg combined. In terms of reliability, this model year recorded just two owner complaints overall, with the electrical system emerging as the primary concern, alongside two safety recalls issued by the manufacturer. This relatively low complaint volume suggests that while the 2018 M240i xDrive was not without issues—particularly in its electrical infrastructure—it did not experience the widespread problems that have plagued some other model years within the 2 Series lineup.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 2018 BMW M240i xDrive dominate in one area — the electrical system, 1 of 2 reports (50%), well ahead of the next concern. That matters, because the electrical system are also the target of recall 17V-719 on this vehicle — so the single most useful check before buying or servicing one is confirming it was actually performed. 0 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the electrical system pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
