信息备份 – NHTS （已更正） new safty rating system

– From freep.com

The BMW 5 Series and Hyundai Sonata were the only new 2011 models to receive an overall 5-star safety rating in the National Highway Traffic Safety Administration’s new safety evaluations.

The revised ratings system will assess each new 2011 model for side pole crash testing and crash-prevention technologies. It also used female crash test dummies for the first time in crash simulations.

Each vehicle received a 1 through 5 score on its ability to withstand front and side impacts. A third score measured the model’s rollover risk. Then each vehicle received an overall rating.

The regulatory agency decided that so many vehicles had reached the highest rating under the old rating criteria that changes in the evaluation process were needed. Under the new, more rigorous standards, not all vehicles will retain their previous 5-star status.

“A change in methodology that creates greater variation in the scores will be far more helpful to consumers,” stated Edmunds.com CEO Jeremy Anwyl. “However, the ideal new ratings system would more closely reflect how consumers think about safety.”

For model year 2011, NHTSA will rate 24 passenger cars, 20 SUVs, two vans and nine pickups under the new ratings system.

The only vehicles to receive a 5 on front crash safety were General Motors’ large SUVS: Cadillac Escalade, GMC Yukon and Chevrolet Tahoe, reinforcing the case that heavier vehicles are safer in head-on collisions.

Toyota Camry received a 3-star overall score, lower than the 4 stars NHTSA gave to Ford Taurus, Chevrolet Malibu and Subaru’s new Legacy and Outback models.
