2015 BMW M235i: Fuel Economy Update for July — New Record

August 14, 2015

2014 Mini Cooper

Our 2015 BMW M235i proves to be a popular car, as it sat in the Edmunds garage only two nights in July. Most of those nights, however, it went home with editors who live in the immediate vicinity of the office. This accounted for 1,322 miles, slightly off pace from our 1,700-mile goal. Something tells me a sunny, top-down road trip is not far off in our convertible's future.

Brent achieved a new single-tank fill record of 26.9 mpg during his highway-heavy commute. A few hundred miles sans traffic boosted the M235i's overall fuel economy from 18.6 mpg to 19.6 mpg, although that's nowhere close to its 21/32/25 city/highway/combined EPA rating.

By nature, performance-oriented cars rarely achieve fuel economy on par with ratings set by the EPA. However, the 5-mpg disparity between the EPA numbers and our own is worrisome. Maybe that road trip will make a difference.
