Luxury cars score low in new crash test

(CBS/AP) DETROIT - Most midsize luxury cars — including the Mercedes-Benz C-Class — performed poorly in a new frontal crash test developed by the Insurance Institute for Highway Safety.

The new test is designed to replicate what happens when a car strikes another car or a fixed object like a tree or utility pole - the type of accidents that kill roughly a quarter of those who are killed in car accidents, reports CBS News correspondent Seth Doane. The test strikes 25 percent of a car's front end into a five-foot rigid barrier at 40 miles per hour.

The results don't bode well for non-luxury models, which will be the next to undergo the new test. Insurance Institute crash test results are closely watched by the auto industry and often lead to changes in design or safety features. Good scores are also frequently touted in car ads.

Of the 11 cars tested, only the Acura TL, Volvo S60 and Infiniti G earned good or acceptable ratings from the institute, which is funded by insurers.

Four cars — the Acura TSX, BMW 3 Series, Lincoln MKZ and Volkswagen CC — earned marginal ratings. Four others — the Mercedes C-Class, Lexus IS 250, Audi A4 and Lexus ES 350 — earned poor ratings. Marginal or poor ratings indicate the cars wouldn't protect occupants very well in a real-world crash.

All of the cars tested were from the 2012 model year.

The institute said the new test indicates that side air bags — which are designed for direct impact, T-bone crashes but not for off-center, frontal ones — may not go off in time or extend far enough to protect occupants. In three cars — the BMW, Mercedes and Volkswagen — the seat belts spooled out too much after the crash, causing the crash-test dummies to strike hard surfaces. The Volkswagen's door was completely sheared off during the test.

CBS News reached out to all the automakers tested. Those who replied stood by their safety record and some said they would incorporate this knowledge into designs moving forward. But Mercedes questioned the testing protocol altogether, saying it mimics an unusually severe and uncommon scenario.

"As a leader in automotive safety, we have full confidence in the protection that the C-Class affords its occupants — and less confidence in any test that doesn't reflect that," Mercedes said in a statement.

Toyota Motor Co., which owns the Lexus brand, accepted the results.

"With this new test, the Institute has raised the bar again and we will respond to this challenge as we design new vehicles," Toyota said.

But Toyota also noted that it has more top safety picks — 17 — than any other automaker.

The Insurance Institute said it plans to change its criteria for the top safety picks next year to incorporate the new test. The group said developed the test after years of analyzing real-world frontal crashes, which kill more than 10,000 people annually in the U.S.

But they cost more, so they must be better-designed and better-built by default!!!!

And where are the cars made?

I just bought the Lexus IS 250, now after the safety ratings I'm not impressed. You would think after a $40,000+ purchase the manufactures might consider the safety aspect. Guess not.... Looks like by the add they only pick and choose what cars they focus on. When a car is considered less than satisfactory it might be a trade in...

Most accidents are driver error, so why burden the manufacturer & penalize us with an inflated price of a safer car?
Wouldn't we be better off without cell phones? How about driver testing that exemplify REAL world driving? Or continuous driver education for insurance discounts?
There is no substitute for intellect or wisdom.

You're being slow. Do you think every accident is between one car and one inanimate object? Most accidents are between 2 cars, where one driver may or may not be in error. Of course we want safe cars to protect those who are not in error, and if you're not too much of a jackass, you want every driver and passenger to be protected, whether they are to blame or not.

Actually, given how CEOs have trampled down on quality, cut costs and wages, to unethically profit for themselves, why should prices go back up? They mooched, so why do you support mooching? THAT comprises the REAL world situation you're blissfully ignoring.

There is, indeed, no substitute for intellect or wisdom.

I am so sick of those Cadillac STS commercials where the car speeds around mountain roads. 45,000 auto deaths a year and we see this crap on TV...Wake Up.

Curious to see how well the Subaru Legacy does. I'm sure it will be better than all.

[hypnotoad72]

That depends... :)

Well come on, that's really upgrading the standard. They are putting huge stress on a very small portion of the front end. They update the test it takes a while for manufacturers to catch up.
