Eunice Lee, the Asian autos analyst at Bernstein, an investment research company, cited Chinese rivals XPeng and Zeekr, whose respective 5C and 5.5C charging systems can add about 280 miles and 342 miles of range in 10 minutes. She was “generally impressed” by BYD’s claims, after it had lagged behind rivals.

Other haughty claims with the new platform include a new electric motor design that operates at over 30,000 rpm and new silicon carbide power microchips to support the battery and drivetrain. BYD says its new chip has a voltage rating of up to 1500 volts, and the vehicles have a 1000-volt charging system.
