前面撞击测试是基于车以每小时35Miles的速度撞墙,这样等同于两辆相类似的车(重量相差不超过250磅)以每小时35Miles的速度迎头相撞。7 \) P h- q* k2 T

例如Civic (重2749磅)和 Accord(重3246磅)是不可以直接比较的(两者前撞都是5星),也就是说,如果用两者以每小时35Miles的速度迎头相撞,测试结果会改变,Accord会更好。" H2 m @6 }& q2 ?

这只是测试结果,是基于已经发生了。至于什么车发生的事故较多,我不知道,这也是另外的问题了。7 [ T; O& t; ?: r

For frontal crash ratings, crash-rating dummies representing an average-sized adult are placed in driver and front passenger seats and secured with the vehicle's seat belts. Vehicles are crashed into a fixed barrier at 35 miles per hour (mph), which is equivalent to a head-on collision between two similar vehicles each moving at 35 mph. Since the rating reflects a crash between two similar vehicles, make sure you compare vehicles from the same weight class, plus or minus 250 lbs., when looking at frontal crash star ratings.
