The M6 does have a four-door version, named the M6 Gran Coupe. Its body dimensions are: length 5016mm, width 1899mm, height 1406mm, wheelbase 2964mm, front track 1631mm, rear track 1612mm, fuel tank capacity 80L, and curb weight 1985kg. The M6 Gran Coupe is equipped with a 4.4T twin-turbocharged engine, delivering a maximum power of 412kW and maximum torque of 680Nm, paired with a 7-speed dual-clutch transmission. It features a double-joint spring strut front suspension and a multi-link independent rear suspension.

As a enthusiast, I often research high-performance models. The BMW M6 indeed has a four-door version called the M6 Gran Coupe. It was produced between 2014 and 2018, based on the standard 6 Series Gran Coupe but more powerful, equipped with a 4.4-liter V8 twin-turbo engine delivering up to 560 horsepower, accelerating from 0-100km/h in just about 4 seconds. I love its design—the elegant lines of a two-door coupe combined with the practicality of four doors, offering much more rear space, making it comfortable for long trips with friends. The handling is precise, and it remains rock-solid during high-speed cornering, yet the suspension tuning ensures a smooth ride without being too harsh. For daily commuting, its intelligent driver assistance features are very practical. Unfortunately, it has been discontinued and replaced by the M8, but you can still find this classic on the used car market. For those who want to balance passion and family needs, the M6 Gran Coupe is a perfect choice—I highly recommend test-driving it to experience the charm of this high-performance sedan.

I've driven several BMWs, and the M6 four-door version is one I've personally experienced—it's highly practical. With a longer wheelbase, the rear seats can accommodate three people, making entry and exit convenient, unlike the two-door coupe that requires tilting the front seats forward. The four-door design eliminates the awkwardness of getting in and out, making it ideal for city commuting or family trips. Performance-wise, it doesn’t compromise—the same V8 engine delivers crisp acceleration on the highway, accompanied by an exhilarating engine roar. For daily use, the trunk space is reasonable, easily fitting a stroller or luggage. at BMW dealerships is thorough, though fuel consumption is slightly high, potentially reaching 12L/100km in city driving. Overall, the four-door version balances sportiness and practicality. If you prefer a premium car without sacrificing convenience, this model is worth considering. While the price is on the higher side, its strong resale value keeps ownership costs within a manageable range.

The four-door version of the M6 was indeed a real historical model, developed as an M performance variant based on the 6 Series Gran Coupe. Launched in the mid-to-late 2010s, it shared the coupe's 4.4-liter V8 powertrain, delivering a maximum torque of 680 N·m with direct driving feedback. The four-door layout enhanced practicality, offering more spacious rear seating and easier access compared to the coupe. Standard features included adaptive suspension and dynamic stability control, ensuring safety and reliability during aggressive handling. Personally, I admire its mixed-material body construction, which reduced weight and improved efficiency. Although it has since been succeeded by the M8, the four-door M6 represented BMW's precise positioning of high-performance sedans.

When choosing the M6, the four-door version offers additional comfort, and I have driven it on long-distance trips. The luxurious ambiance inside the car is outstanding, with soft Nappa leather seats and excellent sound insulation, resulting in minimal noise at high speeds. The four-door design makes it convenient for picking up elderly family members or children, with wide doors that reduce the risk of collisions. The driver's seat is adjustable and flexible, providing a broad field of vision, and the LED headlights offer ample brightness at night. In terms of fuel consumption, it averages 11-13L/100km, slightly higher in urban areas but still acceptable. Regular maintenance is recommended at authorized service centers, with spark plug replacement intervals around 40,000 kilometers. Overall, as a family-friendly sports car, it is safe and reliable, with excellent crash test results. If the budget allows, the M6 four-door version is a wise investment that balances performance and everyday practicality.

I test-drove the four-door version of the M6, and what impressed me most was its cost performance. Although the price is high, it comes with rich configurations, including four-zone automatic air conditioning and a HUD display. The four-door structure increases cargo capacity, and the rear seats can be folded, expanding the loading space to nearly 500L, making it very convenient for moving or shopping. Engine maintenance isn’t cheap, and the turbocharging system has a short service interval, so an annual check-up is recommended. Compared to the two-door model, the four-door version is about 50kg heavier and accelerates slightly slower by 0.2 seconds, but the difference is negligible in daily driving. The used car market is stable, with a depreciation rate lower than other luxury cars. Overall, if you’re pursuing high performance plus practicality, the M6 four-door version is more suitable for urban life than the pure coupe, especially for users who frequently carry passengers.
