What matters
Both are China-market battery-electric performance sedans with all-wheel drive and manufacturer-published 0-100km/h times near 3.1 seconds. The methods differ, so that near tie cannot decide the purchase.
Key differences
- Xiaomi publishes 835km CLTC range, 3.08-second 0-100km/h acceleration, a 265 km/h top speed, an 897 V platform, and up to 670km of added range in 15 minutes under its stated conditions. That combination favors drivers whose long routes match the available chargers, not buyers comparing one charging headline in isolation.
- Tesla publishes 647km CLTC range, 3.1-second 0-100km/h acceleration with rollout subtracted, a 261 km/h top speed, 250kW peak Supercharging, and 460 hp. Peak charging is not constant, so local charging access matters more than the peak alone.
- Xiaomi introduced the SU7 Max at RMB 303,900; Tesla's checked China configurator listed Model 3 Performance AWD at RMB 339,500. The RMB 35,600 gap comes from different price dates, so only same-day complete quotes can establish current value.
Who it is for
- Buy the Xiaomi SU7 Max if its lower referenced price, longer published CLTC range, and charging behavior fit the routes you actually drive.
- Buy the Tesla Model 3 Performance AWD if Tesla's charging network, local service, software, and cabin controls fit your routine well enough to justify the higher referenced price and shorter published CLTC range.
- Buy neither if you lack dependable charging, local service, acceptable insurance cost, or a cabin workflow you can live with every day.
Watch-outs
- The range, acceleration, and charging figures are manufacturer claims under stated but different methods. Xiaomi's charging claim and Tesla's peak rate are not directly interchangeable, and rollout is subtracted from Tesla's acceleration figure.
- The two prices come from different dates and are not transaction quotes. Insurance, financing, options, tires, charging installation, service access, delivery terms, promotions, and depreciation can outweigh the headline gap.
