☠️ Voyah EV Completes a Tunnel Loop

In a test tunnel in Wuhan, the Passion S entered a turn at 130 km/h, holding about 16° of steering angle. The resulting centripetal force pushed the electric crossover onto the wall, over the ceiling, then back down.

The electric crossover used its speed and the tunnel’s radius to stay pressed against the concrete.

The margin was tiny. A speed drop would reduce the normal force between the tires and concrete, so engineers had to calculate a narrow operating window for the heavy EV.
