Although the automobile market is still in the downward stage in 2020, BYD, as the head force of domestic new energy automobile enterprises, is still making full use of the rhythm of new product listing. Following the listing of Chehan, which has attracted much attention, the main models such as Song PLUS and Tang DM also ushered in the change of models. Then, as the flagship model in the SUV product line, what is the comprehensive performance of Tang DM after the change? How should consumers choose three configurations? We will bring you detailed answers in the following. Appearance and interior-"micro-shaping" has achieved remarkable results, and the comprehensive texture has been greatly improved. With the efforts of design master Iger, the shortcomings of BYD models in design have become history, and even in recent years, many China brands have come to the fore. The front face design of DragonFace of the unified family is not only outstanding, but also the China cultural elements reflected from the whole to the details can successfully attract the attention of domestic and foreign consumers. The overall design of Tang DM after the change is not much different from the old one, but the adjustment of details adds more "sense of value" to 202 1 Tang DM. The overall design of the front part and the air intake grille has not changed, but the slightly enlarged size brings a fuller shape. At the same time, many bright chrome-plated decorations on the front face of the old model were replaced by matte chrome-plated decorations, and the piano painted black decorative boards around the two sides highlighted the layering. The aerodynamic design added in the front and rear enclosure details also reduced the drag coefficient of the whole vehicle from the current 0.37Cd to 0.36Cd. In addition, the size of the new car rim was upgraded from the previous 20 inches to 22 inches. Officials claim that the blackened wheel hub style of Dragon Claw is also more stereoscopic, and the 265/40R22 ContiSportContact5 series tires are expensive. The price of a single tire is as high as 2 100 yuan. This kind of tire emphasizes handling and high-speed driving, which is very suitable for road driving. With the braking system provided by Brembo, the visual effect of performance car is brought, which lays the foundation for handling and braking performance. The interior of 202 1 Tang DM has greatly improved in appearance. The ultra-fiber suede fabric widely used from the central control to the door panel, the diamond-shaped stitching on the brown leather seat, the "dragon claw mark" texture on the bright black panel of the central control, and the 3 1 color atmosphere light have significantly improved the luxurious texture of the interior from the whole to the details. In terms of science and technology, the size of the central control screen of 202 1 Tang DM rotatable 90 not only increased from the original 14.6 inches to 15.6 inches, but also adopted the narrow bezel design popular on smart phones at present. The visual sense of technology is enough to impress people in today's production models. In addition, the DiLink3.0 intelligent network connection system used in the central control panel also has a brand-new UI design, which not only has excellent interface effect, but also is extremely smooth to use. In the shift area under the central control, 202 1 Tang DM has also been completely changed. The new car adopts a brand-new design language officially declared as BYDhear "Long Zhixin". In addition to the common function buttons such as one-button start and electronic parking, shortcut buttons such as driver assistance, air conditioning control and driving mode are also integrated in this area, so it is very important for drivers to design a more integrated and highly integrated shortcut control area. In terms of comfort and technology configuration, 202 1 Tang DM also continues the advantages of BYD. Compared with the old model, the new car can now remotely control the air conditioner for high-temperature sterilization directly through the mobile APP to ensure the safe and hygienic environment inside the car. The clairvoyance mode of the new car also allows users to view the camera images inside and outside the car or remotely control the vehicle through the mobile phone, but users do not have to worry too much about privacy issues. BYD officially introduced that this configuration adopts bank-level security measures to protect users' privacy. In addition, the 12 Dirac hi-fi speaker from Denmark not only has an excellent listening experience, but also has a visual effect similar to the shape of the string cover. Size and space-the seats are luxurious and comfortable, and the performance in the back row exceeds expectations. Because it is a mid-term modified model, the overall shape of 202 1 Tang DM is consistent with the old model, and the body size is also consistent with the old model. As a standard 7-seat medium-sized SUV, Tang DM's body width, height and wheelbase dimensions have excellent performance in its class. Although the size parameters of the car stereo have not changed, the seats in the car have been significantly improved compared with the old models. First of all, the appearance of the car adopts the color of red rabbit brown, and the dragon forest shape with diamond stitching is added, which has a very high visual effect. In terms of ride experience, the new car not only improved the seat material, but also carried out a new upgrade in support. Front seat heating and seat ventilation are standard, and the seat adjustment button is finally placed on the lower side of the seat that most people are used to. Because the power battery is arranged on the chassis, the internal space of Tang DM, as a plug-in hybrid car, is not obviously occupied, and the ample rear seat space, flat rear floor and large luggage volume are satisfactory in riding and loading. Power driving-only "fast" is not broken, and the overall comfort is biased towards power. Tang DM continues the three power configurations of the old models, but thanks to the optimization of motor output performance and control program, the acceleration time of the high-performance version is shortened from the previous 4.5s to 4.3s, which is also intuitively reflected in the tail logo of Tang DM. After the comprehensive test drive experience, we found that under the four driving modes of sports/economy/snow/cross-country, Tang DM showed different personalities, but no matter which driving mode, it was full of some "excess" power performance that was the most memorable feature. The engine, motor and gearbox of the hybrid system are well matched, and the action is extremely subtle when switching. As long as there is enough power during driving, the hybrid system will be resolutely implemented in any mode. In terms of chassis and driving quality, the setting of Tang DM is obviously biased towards comfort and home use. Lightweight and compact steering reduces the "sense of volume" as a medium-sized SUV, but the large body size brings a very easy-to-use driving style, which makes us very surprised. It is worth mentioning that the upgraded FSD variable damping shock absorber can better iron the road surface and cope with continuous bumps more calmly, and at the same time significantly increase the chassis thickness.
