BMW X1 review - MPG, CO2 and running costs

The BMW X1 comes with two petrol and two diesel engines. The three-cylinder turbo petrol sDrive18i has claimed economy of 42.8mpg and CO2 emissions of 149g/km with the manual gearbox and 42.2mpg and 152g/km for the automatic version. Move up to the turbocharged four-cylinder sDrive20i, and economy only dips a little, to 40.9mpg, and emissions rise to 156g/km. This model comes with the eight-speed auto as standard. 

Bar the hybrid version, the diesels are the most efficient models in the X1 range, with the front-wheel drive sDrive18d returning the best economy of 55.4mpg with the six-speed manual. When fitted with the eight-speed auto, economy drops to 52.3mpg. Emissions are 133g/km and 140g/km, respectively. Adding xDrive to the 18d sees the figures drop to 51.4mpg and 145g/km for the manual, and 50.4mpg and 147g/km for the auto. At the top of the range, the xDrive20d is auto-only and manages 49.6mpg and emissions of 148g/km in SE trim. 

BMW claims the xDrive25e will achieve figures of between 148.7mpg and 166.2mpg, depending on chosen trim, with CO2 emissions of between 40g/km and 43g/km.

Insurance

The BMW X1 falls into insurance groups from 22 to 30, which is similar to rivals. However, BMW could reduce the X1's ranking if it added autonomous emergency braking as standard to the range. At the moment, it's part of the Driving Assistant Plus package which comprises front collision warning, high-beam assistant, traffic jam assist, lane departure warning and speed limit information.

Depreciation

The BMW X1 has residuals around the 45-49% mark, which is a bit behind some rivals. In comparison, the Volvo XC40 is in the 54-56% ballpark.
