4 Series is a coupe under the BMW brand. Taking the 2021 BMW 4 Series as an example, its body dimensions are: length 4773mm, width 1852mm, height 1395mm, wheelbase 2851mm, fuel tank capacity 59l, trunk capacity 440l, and the body structure is a 2-door 4-seat hardtop coupe. 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, paired with an 8-speed automatic transmission. It adopts a front suspension type of double-joint spring strut front axle and a rear suspension type of multi-link independent suspension.

The 4 Series is a sporty sedan lineup from BMW, and I think it's really cool, perfect for those who enjoy driving pleasure. Whether I'm commuting to work or going for a weekend drive, it feels precise to handle, with quick steering response and no body roll in corners. It comes in three-door, convertible, and four-door Gran Coupe versions. Personally, I prefer the Gran Coupe because the rear seats are practical—even fitting a baby seat is no problem. Engine options range from four-cylinder to six-cylinder. For example, my 430i's 2.0T packs enough punch for easy highway overtaking, and its fuel consumption in the city isn't as high as you might think. In short, this isn't just a grocery-getter; it's the kind of car that puts a smile on your face when you drive it.

As the sporty branch of , I've always admired the technical details of the BMW 4 Series. From the chassis tuning perspective, the suspension is firm yet not jarring – I tested it on mountain roads with strong grip, stable electronic assistance systems, and almost no understeer during turns. The engine lineup is diverse: the entry-level 420i suffices for daily use, while the 430i and 440i are more aggressive. BMW's turbocharging and lightweight design ensure a balance between performance and efficiency. Compared to the 3 Series, it has a shorter wheelbase, lower body, and optimized center of gravity, significantly enhancing cornering fun – driving it feels like flying close to the ground. Maintenance-wise, parts are pricier but highly reliable with fewer minor issues. I recommend test-driving personally to feel the differences when choosing.

The 4 Series was officially launched in 2013. I understand that it was separated from the 3 Series platform and specifically developed as a coupe lineup. Before being named the 4 Series, BMW had similar models during the E90 era, which later became independent to target the sports market. The lineup includes the Coupe, Convertible, and Gran Coupe. I've driven the second-generation F32, which features a more streamlined design and numerous interior upgrades. The powertrain retains BMW's classic inline-six-cylinder engines, though entry-level models use four-cylinder units to reduce costs. To date, the 2023 model has introduced electrification options while preserving the driving DNA. Overall, it's BMW's sincere effort to cater to younger buyers.

In terms of design, the 4 Series left a deep impression on me, especially its iconic large grille, which looks both domineering and modern. Sitting inside, the leather seats offer moderate firmness, preventing backaches during long drives, and the interior layout is clean with an easy-to-use iDrive system. I prefer its Gran Coupe version, featuring an elegant fastback design and more spacious rear seats compared to the regular Coupe, making family trips comfortable. Compared to the Audi A5, the BMW 4 Series has more aggressive lines and a wider range of color options, catering to owners seeking individuality. Although slightly more expensive, its materials and craftsmanship justify the price, and daily maintenance is straightforward.

From a market competition perspective, the 4 Series sits in the luxury sports sedan segment. I've studied competitors like the Mercedes-Benz C-Class Coupe and Audi A5. It leans more towards driving pleasure, while Mercedes emphasizes comfort and Audi focuses more on technology. In terms of pricing, the 430i starts at around 400,000 RMB, slightly more expensive but with high resale value. I recommend opting for the sports package to enhance its appearance. From a practical standpoint, the Gran Coupe version better accommodates family needs and offers better value compared to the two-door version. Maintenance costs are moderate, with longer intervals between oil changes. Overall, it's a great choice for those with ample budgets seeking performance, and it holds its value well even after several years of ownership.
