U9 and U9 Xtreme. The distinction that matters.

A shared name, a specific result

The regular Yangwang U9 and U9 Xtreme belong to the same supercar story, but the latest 503.17 km/h result belongs to the Xtreme. Naming the variant accurately is the first step in comparing the cars.

Engineering for the attempt

The FIA describes the Xtreme’s four independently controlled motors, output above 3,000 PS and 1,200-volt architecture. Specialised tyres, suspension settings, aerodynamics and thermal management also form part of the high-speed picture.

Compare complete configurations

Power and peak speed describe only part of a car. When reading specifications, check the date, variant and configuration. A headline result from a prepared speed attempt should be understood together with its test conditions. Consult the manufacturer’s model-specific material for equipment and purchasing details.
