BMW M4 does not have a 4-door version, the M4 only comes in a coupe version. The BMW M4 is equipped with a 3.0-liter twin-turbocharged inline six-cylinder engine, which has a maximum power output of 317 kW and a maximum torque of 550 Nm. The engine reaches its maximum power at 5,500 to 7,300 rpm and its maximum torque at 1,850 to 5,500 rpm. This engine features BMW's Double VANOS and Valvetronic technologies and uses an aluminum alloy cylinder head and block, paired with a 7-speed dual-clutch transmission. The dimensions of the BMW M4 coupe are 4,678 mm in length, 1,870 mm in width, and 1,394 mm in height; the BMW M4 convertible coupe measures 4,678 mm in length, 1,870 mm in width, and 1,398 mm in height.

The BMW M4 is indeed a cool car, serving as the representative of two-door performance vehicles, and it has always been exclusively available in a two-door version. However, during my research, I discovered an interesting point: BMW categorizes all four-door high-performance versions under the M3. If you want the fierce power of the M4 but also need the practicality of four doors, you should look directly at the M3. These two cars share essentially the same engine and chassis tuning—both are powered by the same violent 3.0T inline-six engine producing 510 horsepower, capable of accelerating from 0 to 100 km/h in a blistering 3.9 seconds. There’s a Melbourne Red M3 sedan parked downstairs at my place, with frameless doors and wide fenders, looking far more aggressive than a regular 3 Series. If you’re serious about buying, I’d recommend opting for the all-wheel-drive version—it offers much more stability when starting in rainy conditions.

Many people often confuse the M3 and M4. To put it simply, the M4 is essentially the two-door version of the M3. The current generation of M4 on sale only comes in a two-door coupe variant, while all four-door models are in the M3 series. Last week, I accompanied a friend to a BMW dealership for a test drive. The salesperson pointed to the new M3 four-door with the large kidney grille in the showroom and said, 'This is the four-door performance car you’re looking for.' The carbon fiber roof and the aggressive lines on the hood give it a very sporty look, and the rear seats are surprisingly spacious—perfect for taking the kids out. However, the trunk opening on the M3 four-door is relatively small, so you’ll need to angle a stroller to fit it in. If you’re into drifting, remember to opt for the heated steering wheel—gripping a freezing leather wheel in an open parking lot during winter is no fun.

To be precise, the four-door M4 is currently unavailable. BMW's product lineup is quite clear: M Cars with odd-numbered designations all come with four doors. I've driven the latest G80 platform M3 at a track day, and its S58 engine, the same as the M4's, is incredibly fierce. The stock exhaust's backfire pops are much louder than the previous model. The interior comes standard with carbon fiber seats that offer excellent support, but those with back issues might want to opt for the comfort seats. The most practical feature of the four-door version is the 40/60 split-folding rear seats. Last time, I helped my brother transport a racing helmet by simply tossing it into the trunk. If you frequently carry passengers or cargo, the four-door M3 is far more convenient than the two-door M4.
