2024 New Energy Super Test: Mountain T1's Performance in the Harshest Winter Conditions

The concentrated testing for the new energy super test of Automobile House in 2024 has been completed. This report will provide an analysis of Mountain T1's performance in terms of range, consumption and charging in the two regions - the low-temperature zone and the cold region.

This year's new energy super test was conducted in the Beijing-Tianjin-Hebei region and Inner Mongolia, covering most areas in China during winter. The testing grounds selected represented the lowest temperature conditions for electric vehicle charging and driving experience during winter, focusing on range, charging and consumption. Based on five evaluation dimensions - comfortability, reliability, and more, this test aimed to comprehensively assess the car's overall performance.

Cold Region

The cold region was located in Hulunbuir Lecheng flag of Heilongjiang province, covering an area that is one of the coldest regions in Northern China. The temperature during testing was -20°C to -15°C. In these harsh conditions, Mountain T1 tackled high-speed city traversal and low-speed urban driving for 50% of the total distance.

Range Testing

The Mountain T1 completed a range test from SOC (State Of Charge) 15% on the cold road and started its engine for the first time only when SOC reached 5%. The range was 77.2km, with an overall battery level maintenance rate of 66%.

After the range test, Mountain T1 filled up its fuel tank and then ran a fuel consumption test (regenerative braking) that lasted nearly 110km. According to the test data, the average consumption during charging is 8.55L/100km.

During the range test, the battery maintained SOC from 5% to 25%, after using up the remaining 15% on its own energy. Reaching SOC of 65%, Mountain T1 remained at that charge level and then charged again. According to the data of 24.597kWh of energy input for a total of 77.2km running distance, Mountain T1 in the cold region consumed 31.86 kWh/100km.

The car successfully traversed with air conditioning set at normal temperature without issues during the long-distance driving trip.

Low Temperature Region

In this test stage, the region used is around northern city of Tianjin. Pure electric tests were conducted in low-speed urban driving and high-speed driving for 50% over a distance and an average range was 126.8km.

The next step included filling up Mountain T1's fuel tank again. The car achieved a fuel power consumption of 6.74 L/100km throughout the entire test stage after covering a total route length of about 106km by adding fuel for full electricity.

Charging tests were then conducted starting from SOC of 15% and achieving charging results similar to the cold region in terms of time.

With 23.84 kWh energy input and a range to 126.8 km, Mountain T1's power consumption reached 18.80 kwh/100km.

Comfort Test

Mountain T1 successfully maintained its temperature at around 22-24 degree between -15°C to 20 degrees Celsius without issues.

Performance Summary

The results of the super test, Mountain T1 got a "trustworthy" badge for reliability. The performance analysis of this car is summarized above.
