How was the 1,230 km journey from Shanghai to Beijing achieved without charging or refueling en route? What were the driving conditions?
This challenge covered the route from Shanghai to Beijing, maintaining highway speed limits throughout with an average speed of 104 km/h. The faster the speed, the greater the wind resistance (wind resistance at 120 km/h is 2.25 times that at 80 km/h), posing a genuine test for both electricity and fuel consumption.
The true value lies in the fact that the 1,230 km comprehensive highway range was not achieved simply by stacking a "large fuel tank" or a "large battery," but by achieving sufficiently low levels of both power consumption and fuel consumption under depleted battery conditions. By simple conversion, a comparable fuel SUV would require approximately 123 L of fuel to cover 1,230 km, yet their fuel tanks typically hold only 80-90 L; a comparable pure electric SUV would require about 209 kWh of electricity, while few mass-produced vehicles are equipped with batteries exceeding 130 kWh. Without significant reductions in energy consumption, battery capacity and fuel tank volume represent the respective range bottlenecks for these two energy forms.
Xiaomi Kunlun Super Range Extension bypasses these dual limitations through precise system coupling. The foundation is a 76 kWh battery plus a 60 L fuel tank, effectively equipping the vehicle with two energy sources, while simultaneously keeping highway power consumption and highway fuel consumption under depleted conditions sufficiently low. This is the key to achieving the 1,230 km comprehensive highway range.
