The test was conducted by the media company Sohu. The YU7 Max used 21-inch Michelin Primacy 5 Energy tires. According to the China Light-Duty Vehicle Test Cycle (CLTC) standard, the vehicle should achieve a range of 750 km.
The CLTC standard is a key metric used by Chinese automakers when introducing new models. Besides China's CLTC, there are three main global standards for measuring electric vehicle range: the EPA, WLTP, and NEDC.
The Xiaomi YU7 Max was set to Comfort mode, with low regenerative braking, and the air conditioning at 23-24 degrees Celsius with two fan speeds. Tire pressure was set at 2.9 bar (42 psi), in line with the vehicle's half-load standard. The test route was entirely on the highway.

Two drivers operated the vehicle at the speed limit, along with necessary equipment, simulating a half-load scenario. The test day had a maximum temperature of around 30 degrees Celsius, more favorable than previous tests conducted in nearly 40-degree Celsius heat.
The YU7 Max covered 483 km on the highway before the displayed range reached zero. The average speed during this portion was 99.6 km/h.
The achieved highway range represents 64.4% of the advertised 750 km CLTC range. According to Sohu, this figure is considered average among tested vehicles but still lower than the 80-90% success rate claimed by Xiaomi.
The YU7 Max traveled an additional 9 km before coming to a complete stop. The total range was 492 km, resulting in a final success rate of 65.5%.
Using a supercharger with a maximum current of 400A and supporting up to 1000V at 400 kW, the vehicle can charge from 0% to 100% in 37 minutes, with an average power of 176.3 kW.
There were discrepancies in energy consumption data: the vehicle's display showed 20.2 kWh/100 km, while calculations based on battery capacity yielded 20.6 kWh/100 km. Actual user energy consumption, based on 108.70 kWh charged, was 22.1 kWh/100 km, higher than the vehicle's display.
In a previous interview, Xiaomi CEO Lei Jun stated he personally drove the standard YU7 1,300 km from Beijing to Shanghai with only one charging stop. The standard version has a CLTC range of 835 km. To achieve 1,300 km with a single charge, the car would need a range efficiency close to 80%.
