[Braking Performance Tests]

 Braking performance is determined by the shortness of the distance in which a vehicle can stop and the stability of the vehicle at the time of braking. This test is performed under wet and dry road conditions for a vehicle which has both a driver and a front passenger. The distance it takes for the vehicle to stop and the stability of the vehicle at the time of braking is evaluated for when the vehicle is stopped abruptly while traveling at a speed of 100 km/h.

 Because the temperature of the road surface affects the distance it takes to stop the vehicle, this condition is also specified for this test (dry road surface temperature of 35.0 ±10.0?, wet surface temperature of 27.0±5.0?). However, when it is not possible to maintain these conditions due to the weather, this is noted in the test results.

 Furthermore, because professional drivers are used in these experiments, the distance it takes to stop the vehicle may be shorter than when the vehicle is driven by the average driver.

  • Braking Performance Test Results

  • All test vehicles are equipped with ABS.
  • There were no test vehicles that went beyond the 3.5-meter line during braking.
    Note: Because the weather condition brought the lower road temperature than that which was required for the braking test, there is some possibility that the braking distance is
    slightly short.
  • The test results listed here were got in 2004.
