The new top model BMW X3 xDrive35i features BMW's newest turbocharged 3.0-liter inline-6 "N55" engine combining direct fuel injection, twin-scroll turbo technology and Valvetronic. The N55 engine develops a maximum output of 300 hp at 5,800 rpm, with peak torque of 300 lb-ft available all the way from 1,200-5,000 rpm. Redline is 7,000 rpm.

This engine enables the BMW X3 xDrive35i to sprint from 0 to 60mph in just 5.5 seconds (preliminary). Top speed is electronically limited to 150mph when fitted with the optional Sport Package.

Both the BMW X3 xDrive28i and the X3 xDrive35i will offer not only the most dynamic driving characteristics in their categories, but also by far the most favorable fuel consumption and emission levels within their class. EPA fuel efficiency estimates will be provided closer to the on-sale date in the United States.
