As a driver I care about range and performance, not so much about km/kwh. I get it that the charging cost/km will be slightly higher on the SU7, other than that why would the driver of the car care?
The Xiaomi SU7 Max EV appears to not only be faster than the similarly priced Tesla Model 3 Highland but also has a noticeably better range according to real-world tests conducted by a Chinese media outlet. The results are a good sign for Xiaomi's EV since the company envisions it as a competitor to the likes of Porsche Tycan and Audi e-Tron GT.
