  • Decent to drive, strong diesel engines, good interior tech
  • Bested by Macan dynamically, numb steering, slightly stiff ride, dated interior design

The xDrive20d is the most frugal model in the X3 line-up. According to official figures, the four-cylinder engine delivers a combined 55.4mpg with CO2 emissions of 135g/km when paired with a manual gearbox. Economy improves on automatic models, which can achieve 57.6mpg and 129g/km. Opting for an M Sport model sees a slightly less efficient 52.3mpg and 142g/km (54.3/136 auto).

The xDrive30d manages 49.6mpg and 149g/km (47.9/156 MSport) and the most powerful 35d gets 47.1mpg and 157g/km. BIK rates range from 23-29%.

To help owners get the most miles-per-tank, the X3 is fitted with a number of tricks from BMW’s Efficient Dynamics programme. There’s ECO PRO mode which minimises the fuel used when pulling away, automatic stop-start and the sat-nav is able to recommend the most fuel efficient route. Aerodynamic wheels are also fitted which reduce rolling resistance.
