2021 BMW X4 M Base

Model Highlights

The BMW X4 comes in two basic trims and one high performance X4 M trims, with varying degrees of power delivery. The xDrive30i is powered by a 2.0L turbocharged 4-cylinder engine which makes 248 horsepower. BMW claims a 0-60 time of just 6 seconds for the xDrive30i, making the vehicle pretty quick even by today's standards. The X4 M40i gets an extra couple of cylinders powered by a 3.0L straight 6-cylinder engine, making 382 horsepower. X4 M models take the S58 straight 6-cylinder to new heights producing 473 horsepower and 442-pound feet of torque. BMW claims a 0-60 time of just 4.6 seconds for the X4, the X4 M bring that number down to an astounding 4.1 seconds making it among the fastest in the segment. BMW uses their standard "xLine" and "M Performance" trim designations for the xDrive30i and M40i respectively, meaning that in addition to having different engines, the two trim base models look somewhat distinct as well. The xDrive30i gets unique 19-inch wheels, front and rear under guard elements and silver metallic side skirts. The M40i, on the other hand, gets unique front and rear aprons with exterior accents painted in a high-gloss black color. Though the M40i also rides on 19-inch wheels, the design is unique and the wheels hide bigger brakes for more stopping power. The M40i also gets a unique sport exhaust that allows the user to switch between loud and quiet modes. Inside, the two trims are further differentiated by their interior styling and features. The xDrive30i comes with dark oakwood interior accent strips, chrome instrument bezels and high-gloss black highlights. In contrast, the M40i comes with aluminum accent strips, a sportier steering wheel and grippier seats. The X4 M is engineered with special attention to chassis stiffness, bigger brakes, and adaptive suspension dampeners with custom Sport, Comfort, and Race settings that tailor your experience to your preference. Unique quick ratio power steering tuning aided by heavy duty limited slip differentials and standard X-drive ensure the X4 remains planted wherever it goes. The BMW X4 comes standard with a navigation system, which is displayed on a large 10.25-inch screen in the X4's center console. Driver assistance options on the BMW X4 are pretty numerous and include an active cruise control system that extends to stop-and-go traffic, meaning the car will essentially take care of the gas and brakes even down to bumper-to-bumper traffic. Standard safety equipment includes a blind spot detection system, a lane departure warning system, a frontal collision warning system, rear cross traffic alert system and a speed limit information system.
