In the past two years, BYD's high-end momentum has become more and more fierce. In addition to the sub-brands looking up and taking off, the flagship SUV of the "legitimate eldest son" of the BYD dynasty network, Datang, has finally unveiled the veil. This is the 2026 pure electric 850km four-wheel drive lidar flagship model, with a manufacturer's guidance price of 289,900 yuan. Less than 300,000, you can have this size of "big car", in the end, is it Xiuwai Huizhong or Waiqiangzhong? Today, we will use 2 minutes of reading time to take you through where the "big" is in this car! The first time I saw the actual car, the feeling of size was still very good. According to the example, the length, width and height are 5263 * 1999 * 1790mm, and the wheelbase is 3130mm. The width is close to 2 meters, the height is close to 1.8 meters, park in the parking space, and you will find that it is "fat" than the car next to it. Whether it is visual or book size, it is worth the word big. Even with the popularity of "size inflation", BYD Datang still hopes to gain an advantage on the physical level. This kind of bulk brings not only visual dominance, but also directly determines the baseline of the interior space. However, the parking problem that comes with it may also require the prospective owners to adapt in advance. Power part, the combination of front and rear dual motors has a maximum horsepower of 796Ps and a maximum torque of 810N · m. Although the 130.15 kWh lithium iron phosphate battery causes the car to weigh 2970 kg, the acceleration time of 0-100 km/h can still achieve 3.9 s, and the maximum speed is 250 km/h, which is still the familiar "big flying brick". Before we opened the door, we noticed that BYD Datang was equipped with a semi-hidden design door handle that conforms to the new national standard, retaining the electric elastic opening mechanism and mechanical redundancy structure. For everyday use, it will automatically pop up with just a touch. This is very friendly for female friends with longer fingernails (or someone like me who hates the hassle of knocking on doors). The space part is a pure comfort zone for a large SUV, with a height of 180cm and a weight of 75kg. After adjusting to a suitable driving and sitting position, it is transferred to the second row. The leg space is quite generous, about three punches, and the floor is flat, which is worthy of praise. A lot of people care about the third row. It was also me who sat in it, the legs were not topped to the back of the second row, and there was a certain margin in the head. Although it can not be said that it is luxurious, for a large SUV, this third row is no longer a "small bench", and daily rides are completely OK. As the second top model of the whole series, the configuration is basically to the top. Refrigerator, color TV, large sofa, small tabletop, zero gravity headrest sound... almost everything you can think of for comfort. In terms of intelligence, the Nvidia Orin-X assisted driving chip plus the Celestial Eye 5.0 system, the hardware stack is sufficient. However, there is a small "groove" here: the electric pedal on the side of the car needs to be optional for an additional 9,000 yuan. For a big guy with a car nearly 1.8 meters tall, the pedal is actually quite practical, and this extra expense may make some budget-conscious users hesitate. After a simple lap, "big" is indeed the core label of this BYD Datang: large size, large space, large horsepower, large battery. But “big” also raises a new question: how does the actual energy consumption perform when the kerb mass is close to 3 tons? Can such a wide body be difficult to navigate on congested city roads? And the electric pedal that needs to be optional, is it worth it? These problems cannot be seen just by looking at the parameters. We are working intensively on the deep dynamic experience of this Datang EV, including its real-life endurance attainment rate, the actual performance of intelligent driving assistance, and the chassis filter vibration texture. If you are also interested in this "big guy", please leave a message in the comments area to let us know what you care about the most, and we will let you know what's next!
