BMW's 2018 X3 enters the nameplate's third generation with a redesign that adds a pre-crash accident detection system, extensive infotainment update, and factory trailer hitch, BMW has announced.

While the exterior dimensions of the X3 will remain unchanged, the wheelbase has been extended by 2.2 inches. BMW will offer an M Sport version for the first time that will be known as the X3 M40i.

The X3 XDrive30i will be powered by a 2.0-liter TwinPower turbocharged four-cylinder engine that makes 248 horsepower, which is an 8 hp improvement over the outgoing X3 xDrive28i.

The X3 will also add a color head-up display that's 75% larger, a 10.25-inch touchscreen and gesture control technology that's been introduced to the 7 Series and 5 Series sedans.

The 2018 X3 will arrive at dealerships in November. Pricing will be announced closer to launch.
