2015 BMW M235i: Fuel Economy Update for October: Quiet Month, Incremental Gains
by Cameron Rogers, Associate Editor on November 10, 2015
We added only 1,200 miles to the 2015 BMW M235i's odometer in October, but we still managed to bump the convertible's lifetime average fuel economy from 21.0 mpg to 21.2 mpg. The majority of the fill-ups hovered around the 21 mpg mark, which is also the M235i's estimated fuel economy in city driving.
A couple of trips that Dan Edmunds took to Auto Club Speedway (averaging 26.2 mpg) are responsible for the marginal uptick in fuel economy.
The M235i crossed the 10,000-mile mark in October with Dan at the helm. During our seven months with our convertible, it has mostly stayed around town but is rarely goes unclaimed. Because it hasn't gone on many long-distance road trips, its overall average fuel economy is stuck near the EPA city rating.
With our current best fill at 29.7 mpg, the highway rating should be achievable. Maybe Mike will find a few extra hours in the week and take it on a highway-heavy day trip. He does that sometimes.
