At a speed of 120 km/h, the braking distance of the Hongqi H9 is approximately 70 meters.
This distance is influenced by several factors, including speed, the friction coefficient between tires and the road surface, the performance of the vehicle's braking system, and the driver's reaction time.
According to relevant test data, the braking distance for the Hongqi H9 from 100 km/h to a complete stop is about 38.25 meters.
As speed increases, the braking distance also significantly increases because it is proportional to the square of the speed.
In real driving conditions, the driver's reaction time should not be overlooked. Typically, it takes about 1 second for a driver to react when noticing a hazard, during which the vehicle continues to travel, further increasing the braking distance.
Therefore, when driving the Hongqi H9 at a speed of 120 km/h, it is essential to maintain a sufficient safety distance to respond to unexpected situations and ensure safe driving.
