You pay a premium for the BMW badge, and trim levels like M Sport are not particularly good value, with steep price rises for a few bits of body kit and larger alloy wheels.

Crucially, the majority of the engines emit comparatively low amounts of CO2, making them cheap to tax for the company car buyers who account for a huge swathe of 1 Series sales.
Our True MPG real world economy tests found that most models return close to or above 50mpg in normal driving (the 116d ED Plus is the most efficient and managed 55.4mpg), with the exception of the sporty petrol variants.
