The differences between the BMW X4 and X4M mainly lie in the engine and power. The specific details are as follows: Difference in maximum engine horsepower: The BMW X4 has a maximum engine horsepower of 184 hp; the BMW X4M has a maximum engine horsepower of 480 hp. Difference in maximum engine torque: The BMW X4 has a maximum engine torque of 290 Nm; the BMW X4M has a maximum engine torque of 600 Nm. Difference in top speed: The BMW X4 has a top speed of 210 km/h; the BMW X4M has a top speed of 250 km/h. Difference in maximum engine power: The BMW X4 has a maximum engine power of 135 kW; the BMW X4M has a maximum engine power of 353 kW.

As a car enthusiast, I've experienced both the BMW X4 and X4M, with the biggest difference lying in performance. The X4 typically comes with a 2.0L or 3.0L turbocharged engine, delivering 248 to 382 horsepower, offering a smooth and comfortable ride ideal for daily use. In contrast, the X4M is a beastly version, equipped with an S58 3.0L twin-turbo engine that churns out 473 to 503 horsepower, accelerating from 0 to 100 km/h in just 3.8 seconds. The strong acceleration provides intense back-push force, but the suspension is much stiffer, ensuring rock-solid stability during high-speed cornering, though it feels quite bumpy over speed bumps in the city. The exhaust note is deep and sporty, adding to the excitement. There's a significant gap in fuel consumption—the X4 averages around 9-10L/100km, while the X4M can exceed 13L/100km in urban areas. Maintenance is costlier, with brake components wearing out faster, making it more suitable for drivers who crave extreme performance. The space is similar, but the X4 is more economical and practical.

As an ordinary office worker, I've been driving the X4 for several years and find it more suitable for daily life. Compared to the X4M, the X4 has a softer suspension, making it less bumpy on rough roads, and the seats are comfortably wrapped for long drives. It's also more fuel-efficient, averaging around 10L in the city. A friend let me drive their X4M, which has a powerful 473 horsepower and quick response, making overtaking easy, but the fuel consumption spikes quickly when you step on the throttle, reaching up to 15L in the city, which isn't cost-effective. The brakes are sensitive and the acceleration is quick, but this can be inconvenient in heavy city traffic. The trunk space is the same, making it easy to store things, but the X4M's tires wear out faster and maintenance costs are higher, with insurance premiums doubling. The interiors are mostly similar, with only slight differences in steering wheel feel. Overall, the X4 offers a balanced and worry-free experience, while the X4M is better suited for occasional bursts of excitement.

Focusing on vehicle appearance, I'm a design enthusiast and have driven both the X4 and X4M for exterior comparison. The X4 features a sleek, sloping roofline that exudes elegance and understatement. The X4M, equipped with M Sport package, boasts a more aggressive front fascia with a wider grille and honeycomb mesh, while the quad exhaust tips at the rear highlight its sporty character. Inside, the M-branded steering wheel with red stitching offers a solid grip, and the seats with pronounced bolsters provide excellent lateral support during cornering. The wheel designs are lighter and cooler, complemented by M badges on the door sills. Details-wise, the X4M appears more aggressive while the X4 maintains a minimalist and trendy look. Space remains unchanged, but the enhanced design elements make the X4M more eye-catching, albeit at a significantly higher price.
