BMW X2 review - MPG, CO2 and running costs

The combined cycle fuel economy figures recorded by the four-cylinder units under the X2’s bonnet are fairly impressive. As ever, you’d struggle to match them in real world conditions, but they are competitive with rivals in the class.

Although no longer available on the X2 price list, the front-wheel-drive 18d diesels are extremely economical, with a WLTP combined economy figure of well over 50mpg. Add xDrive all-wheel-drive on the 18d and the figure drops to 50.4mpg or 49.6mpg for cars with an automatic gearbox. 

If you opt for a front-wheel-drive 18i or 20i petrol model, BMW claims you should see an average of 43-45mpg, although upgrading to the four-wheel-drive versions sees a slight fall to around 40mpg.

The X2 PHEV has a 10kWh Lithium-ion battery that offers a little over 30 miles on electric power only, as long as you keep it charged. That takes around five hours from a standard domestic socket, or three-and-a-bit hours if you have a BMW 7.4kWh i Wallbox fitted. 39-41g/km CO2 figures, depending on trim, make the X2 potentially advantageous for company car drivers who’ll face reduced Benefit-in-Kind tax.

Insurance groups

Groups for the X2 range from 22 to 40, depending on which trim and engine combination you go for. All 20i variants are in either group 29 or 30, with the plug-in hybrid cars in similar groups.

Depreciation

Depending on specification, the X2 should hold on to around 47 per cent of its value after three years and 36,000 miles of ownership, with the 18i M Sport model performing a little better at 50 per cent.
