What is considered an excellent braking distance from 100 to 0 km/h?
2 Answers
The standard braking distance from 100 km/h refers to the distance a car traveling at 100 km/h needs to come to a complete stop. Taking current small and compact cars as an example, an ideal braking distance from 100 km/h is approximately 36-40 meters. If the distance is shorter than this range, the car can be considered excellent in terms of braking performance. Introduction to safe braking distance from 100 km/h is as follows: Introduction one: According to the principles of safe driving, the safe braking distance should be one-thousandth of the vehicle speed. For example, at a speed of 100 km/h, the braking distance should be maintained at over 100 meters. Introduction two: Although the braking distance from 100 km/h is around 36-40 meters, when driving at 100 km/h, it takes time for the driver to react in case of an emergency. This reaction time is approximately 0.5-1 second. In just 1 second, a car traveling at 100 km/h can cover 27.7 meters. Therefore, the safe braking distance from 100 km/h should be maintained at over 100 meters.
I've driven several family cars, and a braking distance between 35 to 40 meters is considered quite excellent. For example, my previous car took 38 meters to stop from 100 km/h, with ABS functioning properly, good tire grip, and not too much weight. Factors affecting braking distance include whether the road surface is dry, the degree of tire wear, and the vehicle's maintenance condition—if brake pads or brake fluid are not checked regularly, the distance can easily extend to over 45 meters. Generally speaking, for ordinary sedans, distances below 35 meters are rare, and 35 to 40 meters is already a very safe range, which can reduce the risk of rear-end collisions. I recommend performing brake system maintenance once a year to ensure stable braking in critical moments, which is particularly helpful for daily commuting.
