The engine model specification of the BMW X3 is B48. The BMW X3 is equipped with a 2.0T 4-cylinder engine. Taking the BMW X3 2021 xDrive25i M Sport Package as an example, its body dimensions are: length 4717mm, width 1891mm, height 1689mm, wheelbase 2864mm, and fuel tank capacity is 65 liters. The BMW X3 2021 xDrive25i M Sport Package is configured with an 8-speed automatic transmission, with a maximum power of 135 kW, maximum power speed of 5000 to 6500 rpm, and maximum torque speed of 1350 to 4250 rpm.
I've driven the BMW X3 for several years, and it offers a variety of engine options. The base model like the xDrive30i uses a 2.0-liter turbocharged four-cylinder engine, model B48, delivering 248 horsepower and around 350 Nm of torque. It accelerates super fast, going from 0 to 100 km/h in about 6 seconds, making it very practical for daily commuting, though fuel consumption is around 9-10 liters per 100 km. There's also the high-performance X3 M40i, equipped with a 3.0-liter inline-six B58 engine, producing 382 horsepower. It's incredibly fun to drive, especially on highways, with a 0-100 km/h time under 4.5 seconds, but fuel consumption jumps to around 12 liters. The diesel version, like the xDrive20d, offers 190 horsepower and fuel consumption as low as 7 liters, making it ideal for long-distance driving. I think the choice depends on your needs: for frequent city driving, a smaller engine is more fuel-efficient, while a larger engine is more thrilling for car enthusiasts. In terms of maintenance, BMW engines are quite reliable—just ensure regular oil changes and check the cooling system often to avoid turbo-related issues.
As a car enthusiast, I've studied the BMW X3 engines extensively. The entry-level sDrive20i is equipped with a B48 2.0T gasoline engine producing 184 horsepower, which feels somewhat mild. The mainstream xDrive30i upgrades to a B48 variant with 248 horsepower, offering quick acceleration response and exceptionally smooth pairing with the ZF transmission. Performance enthusiasts love the X3 M40i's B58 3.0T inline-six with 382 horsepower and 500 Nm torque, delivering thrilling exhaust notes at high RPMs and great tuning potential. For diesel options, the xDrive30d uses a B47 engine with 265 horsepower, offering higher torque and better fuel efficiency. All these engines feature twin-scroll turbo technology to reduce lag. Having test-driven all variants, I found the six-cylinder models far surpass four-cylinders in high-speed stability and acceleration, though four-cylinders are more practical for daily use. For maintenance, don't skimp on spark plugs and air filters - always opt for genuine parts for reliability.
