How About The Huawei Seres Aito M8 SUV Electric Car In Winter Testing?

The results of the winter test of the AITO M8 have been revealed: it achieved the highest range and ranked first in the AEB test group!

[Autohome Professional Review] The 2025 Autohome Winter Test is a Guinness World Record-certified large-scale winter vehicle field test in history, covering (but not limited to) 50 mainstream new energy vehicle models! We will conduct multiple tests on these models, including range, charging, air conditioning heating, performance, safety, and off-road capability. This issue's test vehicle is the AITO M8 (parameters|inquiry) 2025 Pure Electric Ultra Six-Seat Four-Wheel Drive version. How will this car perform in the above test items? Let's see how is going.

Who makes AITO cars?

AITO cars are made by AITO Automobile, a brand created through a collaboration between Huawei and Seres (formerly known as SF Motors). Huawei provides technological support, including its smart connectivity features, while Seres is responsible for the manufacturing of the vehicles.

Snowfield high-speed extreme endurance test:

This winter test marked the first time an extreme range test was conducted on a snow-covered high-speed track, ensuring highly consistent road conditions and average vehicle speeds to provide a realistic winter range reference. On the day of the test, the temperature ranged from -25°C to -20°C. Throughout the range test, the interior temperature remained at our set level of approximately 23°C, demonstrating excellent temperature control. After driving 254.1 kilometers, both the remaining battery power and the displayed mileage reached zero. Even near the end of the test, the powertrain and air conditioning systems continued to function normally. The final measured range achievement rate was 40.7%, with an average energy consumption of 38.9 kWh/100km. The official CLTC range of the Wenjie M8 is 625 kilometers, ranking second to last among its competitors, but its measured range achievement rate ranked second in the group, and its average energy consumption ranked third.

Extreme cold charging test:

For this test, we used a cold-charge method, charging the Wenjie M8 at approximately -20℃ using a 120kW charging station. A total of 98.9kWh was charged in 78 minutes; the typical charging range of 30%–80% took 27 minutes, with a peak power of 113.9kW. Before reaching 80% battery capacity, the charging power remained consistently above 100kW, placing its charging efficiency among the best in the group.

Air Conditioner Heating Test in Extreme Cold:

The severe cold weather air conditioning heating test records the temperature rise over 15 minutes to assess the vehicle's basic comfort. To ensure data fairness and rigor, this year's testing method has been upgraded again, collecting temperature data from both the front and rear seats simultaneously, and the average score is taken. In the test of the Wenjie M8, we adjusted the air conditioning mode to the rapid heating mode. The vehicle heated from -20.6℃ to 4.0℃ within the test time, a temperature increase of 24.6℃. The temperature rise in the front and rear seats was basically the same, which is average compared to other models in the same group.

Performance testing：

Low temperature and low-adhesion road surface are the core of testing vehicle's extreme operating conditions. We built a 1.5km long track to test acceleration, braking and stability.

0-100km/h acceleration in snow：

The Wenjie M8 has a maximum power output of 387kW and a maximum torque of 597N·m, which is not particularly outstanding compared to other models in its group. It also boasts the heaviest curb weight in the group. In the 0–100km/h acceleration test, the vehicle took 8.3 seconds, with tire slippage occurring during the initial launch phase. It should be noted that this result was achieved in Comfort mode, as tire slippage is more pronounced in Sport mode. This acceleration performance is only average compared to other models in the group.

0-400m acceleration in snow：

The 0-400m acceleration test further examines a vehicle's mid-to-high-range acceleration capabilities and power output stability. The Wenjie M8 achieved a 0-400m acceleration time of 16.94 seconds, with a top speed of 142.21 km/h. The power output in the mid-to-high range of acceleration felt slightly weak. This result for the Wenjie M8 is only average within its group's 0-400m acceleration rankings.

100-0 km/h braking in snow：

In braking tests, the shortest braking distance for the Wenjie M8 was 87.92 meters. The brake pedal felt a bit soft, and the vehicle's posture control was acceptable, but the ABS intervention was somewhat late, resulting in some pulling to one side during braking.

Off-road test:

The ice and snow off-road test mainly examines the power distribution, limited-slip capability, and scenario-based obstacle avoidance ability of four-wheel-drive new energy SUVs on low-traction surfaces. This time, we designed three tests: snow roller skiing, snow A-shaped slope, and ice and snow split slope. In all three tests, the Wenjie M8's limited-slip system intervened quickly and efficiently, and in off-road mode, the vehicle could automatically raise the chassis to its highest point, making the traversal relatively easy. However, during the ice and snow split slope test, the vehicle exhibited lateral swaying. Additionally, the left side pedal experienced slight scraping when traversing the snow A-shaped slope.

Security Testing:
We also designed two safety tests: emergency lane change on snow and AEB on snow, to examine the handling stability and performance of active safety systems of different vehicles in snow conditions.

Emergency lane change in snow:

In the emergency lane change test, the ESC intervention of the Wenjie M8 was late and strong. It could pass smoothly at 60km/h, but failed to complete the test at 80km/h.

Snowfield AEB:

In the snow-covered AEB project, the Wenjie M8 continued the brand's traditional strengths: it successfully avoided collisions at speeds of 20km/h and 40km/h; and at 60km/h, the system recognized collisions promptly and effectively mitigated them.

What's the best Chinese car brand?

Based on the official Winter Test results above, the AITO M8 SUV Hybrid is one of the best Chinese car brands. With Huawei's advanced autonomous driving technology, AITO cars have quickly gained traction in the Chinese automotive market. Among luxury large SUVs, the AITO M8 has become particularly popular, thanks to its high performance, smart features, and the collaboration with Huawei, making it one of the top choices in its category
