On October 25, the 2025 BYD Tang DM-i was officially launched. The car offers four different configurations with a price range of 179,800 yuan to 207,800 yuan. The interior of the new car continues the current layout, equipped with a double-spoke flat-bottom steering wheel, a 15.6-inch adaptive central control screen, and provides 6-seat and 7-seat layouts. It is also equipped with the DiLink 100 smart cockpit high-end version.

It is worth mentioning that the new car also provides the Yunnian-C intelligent body control system for the first time, and is equipped with aluminum alloy multi-link rear suspension and FSD variable damping suspension as standard. The car is equipped with BYD's fifth-generation DM hybrid technology, and the 1.5T plug-in hybrid dedicated engine has a maximum thermal efficiency of 45.3%. According to the data from Dongchedi, BYD Tang DM-i sold 12,552 units in September 2024.

On June 16, GAC Trumpchi ES9 launched new models PRO+ and MAX+, with prices ranging from 229,800 to 249,800 yuan, and still equipped with a 2.0T plug-in hybrid system. Trumpchi ES9 is actually a plug-in hybrid version of the GS8 oil-electric hybrid model, so the overall design, size, wheelbase, and space all continue the design concept of GS8.

The two new models adopt a new "dragon scale wing shape" and are equipped with hidden door handles, automatic headlights + automatic high and low beams, electric adjustment of exterior mirrors + automatic folding + heating and defrosting, automatic sensing water spray wipers, etc. The car adopts a seven-seat layout, equipped with a 12.3-inch full LCD instrument panel and a 14.6-inch floating central control screen + AR-HUD head-up display system, and equipped with Qualcomm Snapdragon 8155 chip.

Data shows that in September 2024, the sales volume of Trumpchi ES9 was 664 units. Although Trumpchi ES9 was launched in September last year, its total sales volume was still lower than the monthly sales volume of Tang DM-i.

This article compares the BYD Tang DM-i Yunnian 115KM flagship model and the GAC Trumpchi ES9 PHEV 143km PRO+ for readers' reference.

Trumpchi ES9 has more space, but BYD Tang is cheaper

As can be seen from the above figure, Tang DM-i is not as good as Trumpchi ES9 in terms of length, height and wheelbase. Except for the width, the other parameters of Tang DM-i are not as good as Trumpchi ES9. In other words, in terms of riding space and loading space, Trumpchi ES9 is better than Tang DM-i. The third-arrangement space of Tang can only be used for emergency, while the third-arrangement space of Trumpchi ES9 will not be so crowded. However, in terms of luggage compartment volume, ES9 only has the maximum value, and the minimum value is not disclosed, which is probably higher than Tang DM-i.

In terms of power, the comprehensive maximum power of Tang DM-i is higher than that of Trumpchi ES9, but Tang has not disclosed the power consumption data per 100 kilometers, so there is no way to compare. In terms of acceleration and maximum speed, Tang DM-i is better than Trumpchi ES9.

In terms of pure electric range, the Trumpchi ES9 WLTC has a range of 110 kilometers, while the Tang DM-i has a NEDC range of 115 kilometers, which is about the same. In terms of power-on fuel consumption, the Tang DM-i is 5.75L, while the Trumpchi ES9 is 6.18L, with a difference of only 0.43L per 100 kilometers.

In terms of price, the Trumpchi ES9 is 22,000 yuan more expensive than the Tang DM-i, but the former has more space. The top configuration of the Tang has strong power and the Yunniang system, while the Trumpchi ES9's product strength is not good enough, and it has become a brother in distress with the American Ford Equator.

BYD Tang is powered by Yunnian C, and Trumpchi ES9 uses ternary lithium batteries

Comparing the battery and chassis, the BYD Tang DM-i is equipped with BYD Fudi Power's 21.5-degree lithium iron phosphate battery pack, while the Trumpchi ES9 is equipped with Zhengli New Energy's ternary lithium battery. It only takes 0.36 hours to fast charge 30%-80%, while the Tang DM-i takes 0.5 hours. The Trumpchi ES9 is faster in charging. The Trumpchi ES9's fuel tank is 3L larger than the Tang DM-i. The Trumpchi ES9's comprehensive range is 1016KM, while the Tang DM-i is 1150KM, which is not much different.

In terms of chassis, the Trumpchi ES9 and Tang DM-i have the same suspension type, both with front McPherson and rear multi-link suspension. Both have R20 tires. Whether the chassis is good or not depends on the tuning. Since GAC and BYD are both car companies with more than 20 years of technology accumulation, they are very good at chassis tuning. However, Tang has Yunnian C intelligent damping body control system, which adjusts the damping by controlling the solenoid valve of the shock absorber, realizes stepless adaptive adjustment of the damping, suppresses the body roll and pitch, and ensures the vehicle's handling stability.

In terms of comfort configuration, Trumpchi ES9 is slightly better

In terms of smart cockpit, the central control screen of Tang DM-i is larger than that of Trumpchi ES9, which is more convenient for screen navigation and car entertainment. In terms of smart cabin chips, Fengyun T9 uses Snapdragon 8155 chip, while BYD Tang DM-i uses D100 chip, and the latter has a slight advantage in computing power.

In terms of intelligent driving hardware configuration, Trumpchi ES9 is weaker than Tang DM-i. Trumpchi ES9 has 6 ultrasonic radars, while Tang DM-i has 8. In terms of the number of cameras, Tang DM-i has 6, while Trumpchi ES9 has one less camera.

In terms of intelligent driving, both Tang DM-i and Trumpchi ES9 provide L2-level driving assistance functions, including active braking, lane departure warning, 360-degree panoramic imaging, lane keeping assistance, lane centering, road traffic sign recognition, etc. In terms of passive safety, the two cars have the same functions. However, the next configuration of ES9 supports fatigue driving monitoring. BYD has added steering assist lights.

In terms of comfort configuration, the seats of Trumpchi ES9 are made of genuine leather + imitation leather, while the seats of Tang DM-i are all made of genuine leather. In terms of seat functions, the front seats of both models support seat ventilation, heating, and massage functions, and Trumpchi ES9 has a second batch of heating functions. In terms of temperature zoning, Trumpchi ES9 has three-zone air conditioning and rear air outlets, while Tang has two zones, and the air conditioning cannot take care of the rear passengers. Tang DM-i has a fragrance system, while Trumpchi ES9 does not.

In terms of audio-visual experience, Trumpchi ES9 is equipped with 10 speakers of Alpine Audio, while Tang DM-i is equipped with 12 speakers of Dynaudio Audio. In terms of audio-visual experience, Trumpchi ES9 is slightly inferior to Tang DM-i. Tang DM-i has a seat welcome function, while Trumpchi ES9 is equipped with a welcome light carpet. The price has also reached 249,800 yuan.

By comparison, we can see that the Trumpchi ES9 has a larger space and better comfort. However, many potential customers would hesitate to pay an extra 20,000 yuan to buy the Trumpchi ES9 just for a slightly larger space and slightly more comfortable air conditioning and seats, and I am no exception. Especially since BYD has a good reputation and many car owners, if you buy a domestic car with many people, you will definitely not suffer a loss, but the practicality of the Tang DM-i seven-seater is definitely weaker than that of the Trumpchi ES9.
