SU7 Real-World Range Calculator
With the default inputs — SU7 Max, 110 km/h average highway speed, 20 °C and Eco climate control — the calculator estimates about 608 km (378 mi) of real-world range, 67% of the 902 km CLTC rating. The same car at 130 km/h in −5 °C with climate control on Max drops to about 324 km.
CLTC range is optimistic. This calculator estimates what you'll actually see based on speed, temperature, and AC usage.

How this works
- 01CLTC range is converted to WLTP-equivalent at ~78% (industry-typical conversion for Chinese EVs).
- 02Temperature factor: optimal 18-26°C; ranges below 0°C or above 35°C reduce real range significantly due to battery thermal management.
- 03Speed factor: aerodynamic drag scales with the square of velocity; cruising at 130 km/h vs 90 km/h reduces range by ~18%.
- 04AC factor models cabin climate load: 0.78 in Max use (heat or cool), 0.94 in Eco.
- 05Real-world tests by Chinese motoring channels show realistic-to-CLTC ratios of 60-78% depending on conditions; this calculator targets the middle of that range.
- 06For absolute precision, use a long-form trip planner like A Better Route Planner, which models elevation and weather forecasts.
Range FAQ
- What is the real-world range of the Xiaomi SU7?
- In the calculator's default case (110 km/h, 20 °C, Eco climate control) the SU7 Max gets about 608 km, 67% of its 902 km CLTC rating. Under the same conditions the Standard gets about 472 km, the Pro about 560 km and the Ultra about 418 km.
- How much range does the SU7 lose in winter?
- The calculator applies a temperature factor of 0.84 at 0 °C and 0.72 at −10 °C. At 110 km/h with climate control on Normal, an SU7 Max gets about 570 km at 20 °C, 478 km at 0 °C and 410 km at −10 °C.
- What is the SU7's range at motorway speed?
- At 20 °C with Eco climate control, an SU7 Max gets about 661 km at 90 km/h, 608 km at 110 km/h and 542 km at 120 km/h. Aerodynamic drag grows with the square of speed, so the calculator cuts range by 18% between 90 and 130 km/h.
- Why is the SU7's CLTC range so much higher than what drivers see?
- CLTC is China's lab test cycle, with a low average speed and mild temperatures. The calculator first converts CLTC to a WLTP equivalent at 78%, so the Max's 902 km becomes about 704 km, then applies speed, temperature and climate factors. In the default case that leaves about 608 km, 67% of the CLTC figure.
