4 Series is rarely seen because it has weaker practicality and is not highly cost-effective. Here is a detailed introduction to the differences between various BMW series: In terms of models: 1 Series is a compact car, 2 Series is a small coupe, 3 Series is a midsize car, 4 Series is a midsize coupe (including convertibles), 5 Series is a full-size car, 6 Series is a full-size coupe (including convertibles), 7 Series is a luxury D-segment car. In terms of powertrain: i Series is BMW's electric and hybrid series, M is BMW's high-performance and sports car version, X Series is BMW's dedicated SUV (Sports Utility Vehicle) series, and BMW Z Series is BMW's entry-level sports car. The production version of the BMW 4 Series is largely derived from the 4 Series Coupe concept, replacing the original 3 Series Coupe.

The 4 Series is relatively uncommon, mainly due to its niche positioning. It follows a coupe design philosophy—the two-door styling is undeniably sleek, but the rear seats are cramped, compromising practicality. Many family buyers take one look and think, "Forget it, even kids can't stretch their legs in the back," then opt for a 3 Series or X3 instead. Price is another hurdle: the entry-level trim costs nearly 400,000 RMB out-the-door, and with a bit more budget, you could nearly reach a 5 Series. Most buyers weigh their wallets carefully. Additionally, BMW prioritizes volume sellers like the 3 Series and 5 Series, keeping 4 Series production low—dealerships rarely stock display models, forcing buyers to wait. Coupled with the impact of EVs and waning enthusiasm for traditional luxury brands among younger buyers, spotting a 4 Series on the road has become rare.

I'm in car and deal with customers daily. The reason the BMW 4 Series has few orders is simple—it pleases neither side. Young people find it too expensive, while family users consider it impractical. Nine out of ten customers who check out the 4 Series in the showroom end up choosing the 3 Series, which is about 70,000-80,000 yuan cheaper and offers more space. The manufacturer allocates very few units, with only two or three cars per month per dealership, so salespeople lack motivation to push it. Plus, in recent years, people either want to save money or go for green license plates when buying cars, making fuel-powered coupes like the 4 Series less popular. Occasionally, when a true enthusiast places an order, they still have to wait three to four months, resulting in low delivery rates and fewer on the road.

Those who truly appreciate BMW's handling should understand the appeal of the 4 Series, but its have indeed struggled. It's significantly more expensive than the 3 Series, yet the performance boost isn't as pronounced as the M Series, leaving it in an awkward middle ground. In terms of practicality, the coupe's doors make entry and exit cumbersome, and the trunk space is limited, making daily commuting less convenient than a regular sedan. Additionally, limited availability is another issue—last year, when I accompanied a friend to order one, the salesperson said it would take at least six months. Most people don't have that kind of patience. Its rarity on the road is mainly due to low demand, and when you do drive it out, people often ask why you didn't opt for something like a Porsche 718, which can be quite awkward.

From a family user's perspective, my wife and I specifically test-drove the 4 Series when we were car shopping last year. The frameless doors look stylish, but the fastback design makes the rear headroom too low—our child couldn't sit upright in the back. Every time we took elderly family members out, we had to struggle with folding the front seats, which was a hassle. The trunk depth is also insufficient; it couldn't even fit a car seat plus a stroller. At this price point, you're better off a Li L8, where the rear seats can double as a bed. BMW positions the 4 Series as a niche toy, but few people are willing to spend over 300,000 yuan on a toy. In our neighborhood of 200+ cars, I've only seen one blue 4 Series, and it belonged to a single neighbor.

In BMW's product line strategy, the 4 Series has always been a niche model. It shares the same platform as the 3 Series but costs about 15% more, offering no advantage in cost control. Manufacturers naturally prioritize production of higher-profit models like the X5 and 3 Series, with the 4 Series likely having a monthly production capacity of just a few hundred units. Dealerships maintain shallow inventory, making test drives difficult for consumers. Additionally, market trends have shifted—the similarly priced Model 3 Performance offers faster acceleration and fuel savings, appealing more to younger buyers who favor new energy vehicles. Thus, while the 4 Series boasts excellent handling and premium feel, its overall product competitiveness is lacking in the current market, resulting in low visibility on the roads.
