What is the engine model of the BMW X4?

The engine model of the BMW X4 is B48B20B, with a maximum power of 185 kW, maximum torque of 350 Nm, maximum horsepower of 252 Ps, maximum power speed of 5200-6500 rpm, and maximum torque speed of 1450-4800 rpm. The engine of the BMW X4 is a modular engine from BMW, which is a product independently produced by BMW. For daily maintenance of the BMW X4 engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, causing various problems for the engine. To avoid faults, oil should be changed regularly according to usage conditions, and the oil level should be kept moderate. When oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing oil to bypass through the bypass valve, bringing dirt back to the lubrication area, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acid, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from part wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, blocking the filter and oil holes, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the normal operation of the engine but also extends the overall lifespan of the radiator and engine.
In my years of driving the BMW X4, the engine model mainly depends on the year and version. For example, the common 30i model mostly uses the B48 four-cylinder engine, a 2.0-liter turbocharged unit producing around 248 horsepower, which is quite fuel-efficient with an average city fuel consumption of about 9L/100km. The high-performance version like the M40i is equipped with the B58 six-cylinder engine, a 3.0-liter displacement, delivering over 380 horsepower, offering strong acceleration but with higher fuel consumption. BMW updated its engine family after 2018, upgrading from the older N20 to the B series, with technologies like TwinPower Turbo ensuring smooth and efficient acceleration. When choosing a car, the four-cylinder is suitable for family use and economy, while the six-cylinder leans towards performance. Personally, I prefer the B48 for its durability, quiet operation, and simple maintenance—just oil and filter changes keep it in good condition.
As a frequent car repair enthusiast, it's important to clearly distinguish the engine models of the BMW X4 to avoid issues. The standard version like the xDrive30i comes with a B48 four-cylinder engine, a 2.0T design with stable power output; the M40i is equipped with a B58 six-cylinder, delivering strong 3.0T performance. There are differences across model years: for example, post-2019 models more commonly feature the B series, while older models might still use the N20. When inspecting the engine, pay attention to the spark plugs and timing chain. The B58 sometimes consumes more oil, but regular maintenance can prevent problems. For daily driving, 92-octane gasoline is recommended, with the four-cylinder version being more economical for long-distance commuting. Maintenance costs are lower for the four-cylinder, while the six-cylinder offers robust performance but pricier part replacements—consider your budget when choosing to avoid regrets.
After driving the BMW X4 for half a year, my 30i model is equipped with the B48 four-cylinder engine. The 2.0-liter turbo runs very smoothly. It's fuel-efficient for daily city commutes, and a full tank can cover 600 kilometers. When choosing the car, I followed my friend's advice that the B-series engines are reliable, quiet, and hassle-free. If you prefer high-speed driving, the M40i's B58 six-cylinder offers strong power and fast acceleration, but highway fuel consumption exceeds 11L. Overall, BMW engines are well-designed for effortless driving.
