2018 BMW X3 M40i Packs 355 HP and Launch Control

With new compact SUVs from Jaguar and Alfa Romeo, the BMW X3 faces stiffer competition than ever. For 2018, BMW is bringing out an all-new X3, with a 355-horsepower M40i performance model at the top of the heap. That makes it the most powerful X3 ever—at least, until the V8-powered X3 M arrives.

The X3 M40i's 3.0-liter single-turbo inline-six engine is shared with the fastback X4 M40i and similar to the unit used in the new 540i. This engine is paired with an eight-speed automatic transmission that, with launch control, helps the X3 M40i run from 0-60 mph in 4.6 seconds. All-wheel drive is standard for all US-bound 2018 X3s, but BMW promises a "far more pronounced rear bias" for the M40i.

The M40i also receives M Sport exhaust, M Sport brakes, variable-ratio steering, 19-inch wheels, and sportier suspension tuning. Adaptive dampers, as well as 20- and 21-inch wheels, are optional. Read more about the 2018 BMW X3 M40i...
