2021 BMW X3

BMW’s sedans and SUVs regularly earn CR’s recommendations for packing industry-leading comfort and technology into vehicles that are agile, quick, and even fuel efficient. Among luxury brands like Lexus, Mercedes-Benz, Lincoln, and Land Rover, BMW’s SUVs often rank near the top of their category. Models like the X5 are remarkable for having powertrains that accelerate quickly while also managing above-average fuel efficiency. Some BMWs can be bought as plug-in hybrids, with useful electric-only range, or in performance trims, with more powerful engines and stiffer suspensions. BMW’s growing roster of EVs also generally rank high in our tests. Like most luxury cars from European manufacturers, BMWs fall on the expensive side of our assessments of maintenance and repair costs, but some specific models are a good option to buy used. However, shoppers considering a preowned BMW should opt for warranties or budget for repairs.

BMW's redesigned, third-generation X3 adds upscale cabin amenities, technology, and safety features. Most X3s are the 30i version, which uses a 248-hp, 2.0-liter turbo four-cylinder engine. It delivers quick acceleration and returned 24 mpg overall in our tests. The uplevel M40i gets a 355-hp, turbo six-cylinder. As before, its smooth eight-speed automatic transmission and all-wheel drive are standard. The new X3 is super quiet inside, with impeccable fit and finish. Handling is quite responsive, and the ride is firm yet absorbent. The latest generation of the iDrive infotainment system has been simplified. Blind-spot and lane-departure warnings, as well as low speed automatic emergency braking, are common options. A rear-wheel drive sDrive30i is added for the 2019 model year. The 2020 model adapted the latest iDrive version, and made Apple CarPlay standard. Updates for 2021 included standard lane departure warning and blind spot warning.
