2015 BMW X1 Fuel Economy

7.0
Fuel Economy

Despite its crossover styling, the X1 really functions more as a small wagon, and gets similar fuel economy ratings, too. In fact, two of the available models earn better than 25-mpg in combined conditions.

The X1 powered by BMW's turbocharged in-line six-cylinder isn't one of those models. It's rated at 18 miles per gallon city, and 27 miles per gallon highway, for a combined rating of 21 mpg. It doesn't offer stop/start; its six-speed automatic isn't designed to handle the mechanical stresses induced by the system.

Both of the engines in the 2015 BMW X1 are fuel-efficient; although in the 35i, mileage drops precipitously when you give in to temptation.

The more efficient versions are the sDrive28i and xDrive28i models, which have the turbocharged four-cylinder engine. The rear-drive X1 gets 24 miles per gallon city, and 34 miles per gallon highway, the agency reports, with a combined rating of 28 mpg; with all-wheel drive, the turbo-four X1 is scored at 22/33 mpg and 26 mpg combined.

Four-cylinder models come equipped with an ECO PRO function and stop/start. ECO PRO maps the X1's throttle and eight-speed automatic transmission shift points, as well as its climate-control settings, to help with small, discrete gains in fuel economy. Stop/start offers more measurable differences, and although the system can be unexpectedly jarring at times, it's smoother than the one we've observed in BMW's six-cylinder-powered cars.
