The M40i engine can move the X3 to 60 mph in just 4.6 seconds and top speed of 155 mph. All engines utilize "Valvetronic" variable valve timing and high-precision direct fuel injection.

The X3 M can also be upgraded to the competition package for even more power, over 503 horsepower and 442 lb-ft of torque. Styling one would expect to see on an M vehicle such as larger air intakes, double-barred kidney grilles, unique wheels, updated bumper styling along with aerodynamically proficient wing mirrors, unique brake calipers, and loads of other options including carbon fiber add-ons all come along with the X3 M vehicles as well. The X3 is also offered as a plug-in hybrid, it offers electric-only driving combined with a gasoline-fueled engine for reassurance and optimal fuel efficiency. With any engine, the X3 is paired with a responsive and quick-shifting 8-speed ZF automatic transmission, which includes an Eco Pro mode that helps improve fuel economy by optimizing heating and air conditioning use, softening accelerator response and tweaking shift points. All models also have Auto Start/Stop, which shuts off the engine when idling at stoplights, and Brake Energy Regeneration, which saves fuel by optimizing alternator use. Fuel economy ratings are 24 mpg city, 29 highway with the xDrive30i, or 21 mpg city, 27 highway with the M40i. Each model of the X3 offers the xDrive intelligent all-wheel-drive system, which works together with the dynamic stability control electronics to intelligently send power to the wheels for confident traction and handling in all road conditions. The xDrive30i as a luxury crossover SUV comes with a host of desirable standard features. Exterior features include run-flat tires on 18-inch wheels, LED headlights and fog lights, power liftgate, power-folding heated side mirrors and the iconic BMW "kidney" grille with active grille shutters.
