In today’s automotive market—especially in the family SUV segment—consumers are faced with an overwhelming range of options. It is no exaggeration to say that, within the mainstream family budget, SUVs have become the preferred choice for many young families and middle-class households. Among them, the BYD Tang L DM and the Li Auto L6 are two of the most talked-about models. Today, let’s take a closer look at these two vehicles and find out which one truly deserves the title of “the ultimate family SUV”.
From a user’s point of view, buying a car today is no longer just about basic transportation. It is about meeting the growing and increasingly diverse needs of a family—such as space, comfort, intelligent technology and power performance. That is exactly why these two models have attracted so much attention in the market.
The BYD Tang L DM measures 5,040 × 1,996 × 1,760 mm, with a 2,950 mm wheelbase, and comes in a five-door, seven-seat layout. The third row can comfortably accommodate adults, and when folded down, the trunk can be expanded to up to 1,960 liters. It easily meets the needs of multi-child families and three-generation households, whether for daily family trips or carrying large items, making it suitable for a wide range of family-use scenarios.By comparison, the Li Auto L6 is slightly smaller in terms of overall dimensions. It adopts a five-door, five-seat layout, with a body size of 4,925 × 1,960 × 1,735 mm and a 2,920 mm wheelbase. It is more suitable for a family of three or a couple. When temporary multi-passenger trips are required, its practicality is limited, and its space disadvantage becomes particularly noticeable for larger families.
At the same price level, the Tang L DM offers ventilation, heating and massage functions for both the front and second-row seats, along with third-row air-conditioning vents and an electrically operated dual-layer onboard refrigerator. The configuration is truly comprehensive, ensuring a comfortable experience for passengers in every row.In contrast, the Li Auto L6 only provides ventilation, heating and massage for the front seats, while the second row does not offer a massage function. The onboard refrigerator is only available on higher trims. Even though the Li Auto L6 Pro comes with improved equipment, it still falls behind the Tang L DM at the same price point. The absence of several key comfort features significantly compromises the rear-seat experience.
The Li Auto L6, however, only supports navigation assistance on highways, while in urban areas it mainly provides basic lane-keeping functions. In complex city scenarios, the driver needs to take over frequently, which limits the usefulness of its intelligent driving functions in everyday urban use.The key highlight of the Li Auto L6’s intelligent cockpit is its three-screen, zero-interference interaction system. The three displays are dedicated to the driver, center screen and front passenger, enabling seamless information transfer without complicated operations. During driving, the front passenger can independently watch videos or listen to music without affecting the driver, and the driver’s driving information is not disturbed by passenger operations. The interior design of the Li Auto L6 is built around this concept.However, its front-to-rear interaction logic still has shortcomings. For example, although rear passengers can adjust the temperature, they cannot adjust the fan speed, which must remain synchronized with the front row. If you happen to sit in the middle seat on a hot day and need strong airflow, you may be exposed to direct air blowing on you. For families who frequently travel with five occupants, the rear middle seat is therefore not ideal for elderly passengers or children.

Let’s first look at power performance. Thanks to BYD’s fifth-generation DM technology, the Tang L DM shows virtually no power degradation at an altitude of 4,298 meters. Its fuel consumption in low-battery conditions is only 5.5–5.6 L/100 km, and it runs on 92-octane gasoline. With a full tank and a full charge, its combined driving range exceeds 1,400 km.Whether climbing steep roads or overtaking, throttle response remains strong and immediate. Even when fully loaded and driving on winding mountain roads, it performs effortlessly, with almost no noticeable difference compared with driving at low altitude. Daily commuting can be done purely on electric power, keeping running costs very low.
By contrast, the Li Auto L6 shows clear power disadvantages at high altitude. Delayed response can be felt right from initial acceleration. Although its official 0–100 km/h time is 5.4 seconds, its fuel consumption in low-battery conditions ranges from 6.9 to 8.1 L/100 km, and it requires 95-octane gasoline.When climbing, sluggish power delivery becomes particularly obvious, and overtaking requires deep throttle input. Compared with its performance at low altitude, the difference is very noticeable. The impact of thin air on its power output is significant, which is clearly reflected in real-world test feedback. Under the same mileage, fuel costs are considerably higher. Its combined driving range is about 1,390 km, slightly lower than that of the Tang L DM. In high-altitude usage scenarios, both power and efficiency limitations noticeably affect the overall experience.
After test-driving the BYD Tang L DM, the most impressive takeaway is that it truly lives up to its reputation as an all-rounder. Whether in urban traffic—such as car-following and lane changes—or on highways with navigation assistance, its operation feels smooth and natural. Both new and experienced drivers will find it easy to use.Its overall ride quality and interior configuration are also well executed, and attention to detail is clearly evident throughout the vehicle. Of course, no car is perfect. If there is one minor drawback, it would be the exterior design. The styling is more conservative and family-oriented, with fewer youthful or sporty elements. For younger buyers who value individuality and trend-driven design, it may not appear particularly eye-catching. However, for family use, the design is durable, refined and well aligned with mainstream tastes.
As for the Li Auto L6, subjectively speaking, it does not feel like a typical mid-size SUV when driving. It delivers a noticeably “light” driving feel, especially on highways, which makes it very easy and comfortable for the driver. This lightness is indeed well suited to family usage.However, this tuning mainly benefits the driver. Rear-seat passengers may find the experience less comfortable due to the lack of the “solid and planted” feel that is usually expected from a mid-size SUV, and motion sickness is more likely to occur. In this respect, BYD’s tuning feels more refined, offering strong acceleration while maintaining a driving experience that is closer to that of a traditional gasoline vehicle.Li Auto officially emphasizes the L6’s “agile body and easy driving and parking,” and this description is accurate. From a static perspective, it is a comfortable family SUV, and the interior quality of the Li Auto L6 is widely recognized. However, once on the road, family members who have little experience with new-energy vehicles may need some time to adapt to its driving characteristics.

Overall, the BYD Tang L DM clearly outperforms the Li Auto L6 in terms of space and practicality, equipment level, intelligent driving scenario coverage, and energy efficiency. With its family-oriented tuning as a core advantage, the Tang L DM is better suited to the diverse needs of larger households.The Li Auto L6 mainly stands out in terms of comfort for a five-seat layout. However, even with the upgraded Li Auto L6 Pro, it still cannot overcome the inherent limitations when it comes to multi-person family usage, making it more suitable for smaller families.Therefore, for buyers within the mainstream family-car budget who are looking for a truly practical family SUV, the BYD Tang L DM is the better overall choice. Its all-round product strength delivers a more comfortable, more convenient and more economical travel experience for the entire family.
