BMW X3

The X3 is a compact luxury crossover SUV with room for up to five passengers. In BMW’s sport-ute lineup, it sits between the subcompact X1 and the midsize X5. Related models (reviewed separately) include the sportier BMW X4, which shares the same platform but features a coupe-like design, and the X3 M, a high-performance variant. The X3’s most recent (third) generation, known as the G01, debuted in 2018, featuring more aggressive exterior styling and an upgraded cabin with new tech and safety features. Properly equipped, the X3 can tow up to 4,400 pounds.

Through the years, BMW has offered the X3 in a variety of trims, which typically correspond to the included powertrain. Prior to its 2018 revamp, the primary trims were the four-cylinder-powered xDrive28i and six-cylinder xDrive35i. With the introduction of the third generation in 2018, the lineup expanded to include the four-cylinder xDrive30i (replacing the xDrive28i), the performance-oriented M40i, and later, a plug-in hybrid (PHEV) variant called the xDrive30e.

Under the hood, the xDrive28i features a 2.0-liter turbocharged four-cylinder engine with 240 horsepower, while the xDrive35i utilizes a 3.0-liter turbocharged inline-six, which increases output to 300 hp. A diesel variant, called the xDrive28d, was also available through the 2017 model year. The third generation’s xDrive30i retains the 2.0-liter turbo four-cylinder but increases output to 248 hp, while the range-topping M40i comes with a more potent 3.0-liter turbocharged inline-six making 382 hp. The xDrive30e, introduced in 2020, combines the 2.0-liter turbo four-cylinder with an electric motor and a small lithium-ion battery pack, offering a total output of 288 hp and an all-electric range of up to 18 miles. All available engines pair with an eight-speed automatic transmission, which routes power to all four wheels in xDrive models, while those with sDrive get rear-wheel drive.

The third-gen X3’s 2018 launch introduced a revamped iDrive infotainment system with a standard 6.5-inch display and an optional 10.25-inch touchscreen. Apple CarPlay integration has been standard since the 2019 model year, while Android Auto joined the following year. The model’s advanced safety features have evolved similarly. In 2018, BMW made its Active Guard safety suite standard across all X3 trims, adding forward-collision mitigation, pedestrian detection, rear cross-traffic alert, and lane departure warning. More advanced driving aids, such as adaptive cruise control and blind-spot monitoring, have also long been available but only as options.

We recommend that used car buyers seek out 2018 and newer examples of the X3 due to their updated design, more refined interior, and additional tech and safety features. Specifically, the xDrive30i offers a compelling balance of value, performance, and luxury, while the M40i provides a sportier driving experience. If fuel efficiency is a priority, the xDrive30e plug-in hybrid, introduced in 2020, is a strong choice, as it offers significant fuel savings compared to other X3 trims.
