The Check
On this take a look at, the motive force’s seat is faraway from the automobile and secured to a sled. A midsize male dummy designed for rear impression testing is positioned within the driver’s seat. The sled delivers a sudden pulse of acceleration to simulate the impact of a stationary automobile being struck from behind.
The unique take a look at concerned a single pulse equal to being struck by a automobile touring at 20 mph of the identical weight.

In distinction, automobiles with a superb ranking present that the seat and head restraints preserve the dummy’s head and backbone in alignment. Moreover, automobiles that obtain a superb ranking present wonderful safety throughout all metrics at each speeds. Acceptable rankings point out that automobiles might falter barely throughout a number of areas, whereas marginal rankings point out critical flaws.
To date, solely 4 of the primary 18 small SUVs examined earned a superb ranking: the Audi Q3, Hyundai Ioniq 5, Subaru Foresterand Toyota RAV4.
