Nissan Versa aces crash tests

[Yeo]

The Nissan Versa got top marks in crash test results released Tuesday by the Insurance Institute for Highway Safety, though bigger cars still offer greater safety than small cars the results showed.

The Institute tested eight small cars. Only the Versa earned the top rating of "Good" for front- and side-impact protection as well as for whiplash protection in rear impacts.

Small cars have become increasingly popular as fuel prices have risen and their quality and safety ratings have improved.

But even the safest small car offers less protection in a crash than a larger car, the Institute said.

"People traveling in small, light cars are at a disadvantage, especially when they collide with bigger, heavier vehicles," said Institute president Adrian Lund.

The poorest-performing small cars in this round of tests were the Hyundai Accent and Kia Rio. The Accent received a "Poor" rating in the Institute's side-impact test despite having side airbags as standard equipment. The Accent was rated as "Acceptable" for front-impact protection.

The Accent's steel body didn't hold up well, the Institute said, which resulted in severe impact forces to the pelvis of a crash test dummy in the driver's seat. Rear-seat occupants have no airbag protection in the Accent and a dummy placed there was struck in the head during the side-crash test, the Institute said.

The Accent's crash test results also apply to the closely-related Kia Rio.

The Institute also tested the Toyota Yaris, Honda Fit, Scion xB and Chevrolet Aveo. The Mini Cooper had been tested previously.

The Yaris, when equipped with optional side airbags, earned "Good" ratings in front- and side-impact tests, but rated only "Marginal" in rear-impact whiplash protection. Without the optional side airbags, though, the Yaris was rated "Poor" for side-crash protection.

The Scion xB, a tall, boxy wagon also made by Toyota, doesn't come with side airbags even as an option. Like the Yaris, it earned a "Good " rating for front-impact protection, but "Poor" for side protection and "Marginal" for rear impact protection.

Good performances, but no awards
None of the vehicles in this round of tests earned the Institute's Top Safety Pick Award because they don't offer electronic stability control, which is a requirement for that award.

The Insurance Institute's front- and side-impact tests are different from those performed by the government.

For front-impact safety, the Institute uses an "offset" test in which the vehicle strikes a barrier with just part of its front bumper, concentrating impact forces.

In its side-impact test, the Insurance Institute hits the vehicle with a barrier that resembles the front of a SUV or pick-up truck. That type of impact represents a much graver risk of head injury, and therefore a greater risk of death than an impact from a car. Vehicles without head-protecting side airbags generally perform poorly in the Institute's side-impact test.

Rear-impact safety is calculated by, first, measuring various features of the seat and headrest. If those are judged to seem reasonably safe, the seat is then tested using an actual impact test.
