2013 BMW X3 Fuel Economy

Fuel Economy

Change has come to the X3 lineup for 2013--with a turbocharged four-cylinder replacing the outgoing normally-aspirated six in the X3 xDrive28i.

The new xDrive28i is rated by the EPA at an impressive 21 mpg city, 28 highway, while the 300-hp xDrive35i earns 19/26-mpg ratings. Both versions get the benefit of an eight-speed automatic.

The X3 xDrive28i gets much-improved gas mileage--thanks to a new turbo four-cylinder engine.

U.S. versions now also get the Auto Start-Stop system, which wisely stops the engine at stoplights, with your foot on the brake, then restarts the engine when you start to lift off the brake pedal. Unfortunately in the X3, with the four-cylinder engine, it's a little rough in the way that it shuts the engine off.
