Passive Safety

Mutual safety for vehicles : All-around compatibility

Help ensure safety for both vehicles (of different weights and heights) at the time of collision.

"Compatibility" is the way of thinking that vehicles of different weights and heights should both be safe at the time of crash. Both types should be considered when analyzing safety performance from the impact on the lightweight vehicle to reducing the damage from the heavyweight vehicle. Toyota utilizes the concept of this compatibility in the approach to help improve the collision safety for both the driver's vehicle and the other party's vehicle with a 2 ton class vehicle.

Toyota's effort (approach)

  • 2002 Collision test with "Ist"(Scion xA) and Celsior (Lexus LS) (50 kph)
  • 2003 Collision test with "Prius" and an SUV (50 kph)
  • 2005 Collision test with "Vitz" (Yaris) and 2 ton class vehicle (55 kph)

Toyota conducted vehicle-to-vehicle collision tests at a speed of 55 km/h from the front, side and rear.
The injury values for the passenger area and dummies passed Toyota's strict proprietary testing marks.

Evaluation method (Example: Yaris)

Frontal collision test (both at 55 kph)
