BMW 4 Series is a mid-size car. Taking the 2021 BMW 4 Series as an example, its body structure is a 2-door 4-seater hardtop coupe, with body dimensions of: length 4773mm, width 1852mm, height 1395mm, wheelbase of 2851mm, fuel tank capacity of 59l, and trunk capacity of 440l. The 2021 BMW 4 Series is equipped with a 2.0t turbocharged engine, with a maximum power of 135kw and a maximum torque of 300nm, matched with an 8-speed automatic manual transmission. The front suspension uses a double-joint spring strut front axle, and the rear suspension uses a multi-link independent suspension.

For me, the BMW 4 Series is a stylish and comfortable mid-size coupe. It's built on the 3 Series platform but features a sleeker and more dynamic design, available in two-door, convertible, and practical four-door Gran Coupe versions. I enjoy driving the Gran Coupe version for my daily commute—the rear doors make it convenient for picking up family members, and the trunk has ample space for large luggage. Parking in the city is easy, and the fuel consumption is around 8-9L per 100km, which isn't too expensive. The chassis tuning is quite stable, making long drives comfortable without leg fatigue. The steering feedback is direct, offering a precise feel when cornering, though the rear seat space is a bit tight, making it suitable for small families. Maintenance parts can be pricey, so regular servicing is recommended to avoid issues. Overall, it's a great fit for drivers like me who seek a bit of sportiness without sacrificing practicality.

The BMW 4 Series is the epitome of a cool sports sedan in my mind. It features BMW's classic design with prominent kidney grilles and a low, sleek body that turns heads on the street. I've driven its Coupe version, and the engine response is quick—the turbocharged engine in the 430i delivers exhilarating acceleration, especially in Sport mode, where the sound gets quite thrilling. It offers plenty of driving fun in daily use, and the interior is well-appointed with a digital dashboard and user-friendly buttons, while wind noise is well controlled. Space-wise, the front seats are spacious, but the rear seats are a bit tight, making it ideal for couples or single friends. I chose it mainly for its looks and value for money—the base model is affordably priced, and adding a sunroof makes it even more comfortable. Fuel consumption is moderate, and a full tank is sufficient for long trips, making it an ideal choice for young buyers.

As a car enthusiast, the BMW 4 Series is a compact sports car under the BMW brand, available in three body styles: Coupe, Convertible, and Gran Coupe. I particularly favor its lightweight body and precise handling. It offers multiple engine options—the 420i is sufficient for city commuting, while the high-performance M4 version delivers exceptional power, and the all-wheel-drive system ensures stability. Technical highlights include an 8-speed automatic transmission and active safety systems. The design features a larger grille, giving it a modern look. It drives nimbly, making it ideal for winding roads, though the interior space is somewhat limited, and the sound insulation is decent. Overall, it's efficient and reliable, but regular maintenance is essential.

I own a BMW 4 Series Gran Coupe for family use, which combines sportiness and practicality quite well. Its exterior is sleek and elegant, and while the interior isn't spacious, the rear seats are sufficient for my three kids, and the trunk capacity is adequate for family trips with luggage. I often drive it to pick up and drop off the kids at school—it's easy to steer and fuel-efficient, especially the diesel version. It comes with plenty of safety features, like automatic braking and lane-keeping assist, which give me peace of mind. Maintenance costs are slightly higher, as parts can be pricey, but reliability is decent, with few issues. The price positioning is moderate, making it a good recommendation for families like ours, balancing performance and daily needs. The ride is smooth and comfortable, with no shaking or noise.

I believe the BMW 4 Series represents the essence of BMW, with exquisite design and abundant driving pleasure. It comes in Coupe and convertible versions. I've driven the convertible, and the wind experience with the top down is exhilarating. The sport chassis provides direct feedback, and the M4 model is particularly powerful, delivering strong acceleration and a thrilling push-back sensation. Technically, it uses efficient turbocharged engines, such as the B48 model, which is fuel-efficient, paired with rear-wheel drive or optional all-wheel drive. The interior materials are high-quality, though there's room for improvement, such as the small storage compartments. Overall, it's more aggressive than the 3 Series, making it ideal for driving enthusiasts, with outstanding track performance. For maintenance, pay attention to engine oil and tires, and consider opting for high-performance components. It offers good value for money among luxury sports cars.
