BMW M4 has only two doors. Body dimensions: The BMW M4 is a high-performance sports car under the BMW brand, with a body length of 4678 mm, width of 1870 mm, height of 1398 mm, and a wheelbase of 2812 mm. Power configuration: The BMW M4 is equipped with a 3.0-liter inline six-cylinder twin-turbocharged engine, with a maximum engine power of 317 kW, maximum torque of 550 N·m, maximum power speed ranging from 5500 to 7300 rpm, and maximum torque speed ranging from 1850 to 5500 rpm. This engine is paired with a 7-speed dual-clutch transmission.

I've driven the BMW M4 a few times. This model is typically designed as a two-door coupe, looking particularly stylish and sporty. Every time I open the door to get in or out, it feels as smooth as entering a race car. It has 2 doors, and accessing the rear seats can be a bit tricky, but the overall space is still sufficient. I especially love its acceleration push and the frameless window style. BMW later introduced the M4 Gran Coupe, which is a four-door version with better practicality, but I always feel the two-door version is the authentic one. In the car enthusiast circle, it's widely regarded as the true representative of a performance car. If you're considering buying a used or new one, checking the year can help distinguish them – the Gran Coupe became a four-door model after 2023, but the classic version has always stuck to two doors. In short, fewer doors don't diminish the driving thrill; instead, they add a touch of pure charm.

After repairing BMW M4s for twenty years, I've seen many models, most of which come standard with a two-door design. The Coupe structure is simpler, and door repairs are more straightforward with fewer complex components. However, note that the current M4 Gran Coupe is a newly added four-door model, requiring extra attention to door hinges and seals during repairs. Owners often ask about the number of doors—the vehicle manual or VIN code is the most accurate source. Older models are definitely two-door, with wider opening angles and smaller rear space, but the engine performance is very stable. The key to maintaining such cars is regular upkeep of the door lock system to prevent operational issues. When choosing a car, confirm the model to avoid confusion and later hassles. Fewer doors actually reduce potential failure points, and as long as maintenance is proper, there should be no issues.

From a design perspective, the BMW M4 features a minimal door count with only a two-door coupe configuration. This structure accentuates the sports car's line aesthetics, eliminating superfluous elements to enhance the overall aerodynamic dynamism. The Gran Coupe version introduced an innovative four-door design later, improving practicality, yet the classic M4 maintains its two-door format as a symbol of brand heritage. The door opening ratio is meticulously calculated to elevate the driving experience, with a lightweight body and agile handling, reflecting a performance-first philosophy in door selection. Historically, the two-door version has often been regarded as a benchmark for sports car styling, boasting a unique and timeless appeal.
