PHYSIX OBSERVATION

Achieving a 500 km/h-class top speed on public roads and securing FIA certification shows that Chinese brands have entered a territory previously held only by Bugatti and Koenigsegg in electric drive, high-voltage platforms, and tire coordination. For users, such records are more of a technical endorsement; what is truly worth watching is when the three-electric and thermal management capabilities will trickle down to production models.
