2015 BMW M235i: Fuel Economy Update For February - Slight Boost in Lifetime Efficiency
by Jason Kavanagh, Engineering Editor on March 10, 2016
Our long-term 2015 BMW M235i saw its electron-related features under the microscope during February. Its keyless ignition sans entry, leisurely power-folding top and chicken-little-ing parking alerts came under heavy scrutiny.
In between these ruminations, the BMW also saw a decent chunk of road time during February — 1,215 miles, to be exact. It managed 23.3 mpg for the month, bringing its rolling lifetime fuel economy to 20.9 mpg. This lines up with its EPA city rating of 21 mpg.
The little (-ish) droptop may not ever achieve its EPA combined fuel economy rating during its time with us, but its overall average did trend upward. This is a reversal from January's progress report.

Note: Cars are sometimes refueled well before their fuel tanks approach empty. As such, "best" and "worst" fuel economy entries above are not necessarily the result of an entire tank's worth of driving.
