Roofs of small pickups tested by IIHS, only Frontier/Equator gets good rating

Among all the 2010 model vehicles in the Small Pickup Truck class tested, only the Nissan Frontier, also sold as the Suzuki Equator earned the highest possible rating of “good” from the Insurance Institute for Highway Safety or IIHS http://www.iihs.org. Other pickups tested were the Ford Ranger, which got an “acceptable” rating, as well as the Toyota Tacoma, the Chevy Colorado, a rebadged GMC Canyon and the Dodge Dakota, which all got “marginal”, the second lowest possible rating.

To get a “good” rating from the IIHS, a vehicle must have a roof that’s twice as strong as the current federal safety standard. This requirement is based on the Institute’s research that says passengers of a vehicle with a strong roof have the highest protection against rollover crashes, which is one of the most serious types of vehicular accidents.

According to statistics, rollover crashes are a lot more common in SUVs and pickup trucks than in cars, with almost half of all pickup truck occupant deaths in 2008 attributed to rollover crashes. Having a strong roof does not just reduce the risk of injury from contact with the roof during rollovers, it also prevents people from being ejected out of the vehicle through the windshield, windows and doors opened up after the roof gets deformed.

Even with a “good” rating in roof strength-to-weight ratio, the Nissan Frontier/Suzuki Equator still failed to be a “Top Safety Pick”, because it only earned an “acceptable” rating in protection against neck injury in rear crashes. To be a “Top Safety Pick”, a vehicle must earn a “good” rating in front, side, rear and rollover crashes and have Electronic Stability Control, which reduces the chances of fatal rollovers significantly.

"As a group, small pickups aren't performing as well as small cars or small SUVs in all of the Institute's safety tests. None of the ones we tested is a top-notch performer across the board. In fact, no small pickup earns our Top Safety Pick award," said IIHS Senior Vice President David Zuby.

The National Highway Traffic Safety Administration or NHTSA made a ruling raising the federal roof strength requirement in April of 2009. According to this new ruling, vehicles with a weight rating of 6,000 to 10,000 pounds should be able to withstand a force corresponding 1.5 times of their unloaded weight. The former ruling only required vehicles with a weight rating of up to 6,000 pounds to have a strength-to-weight ratio of 1.5 to 3. Also, the vehicles’ roofs are required to maintain a certain headroom measurement during testing and both sides of a roof will be tested sequentially and each side will be required to meet the said standard. This will be phased-in starting September 2012 and all vehicles will be required to comply with it by September 2016.

Furthermore, the IIHS also conducted side impact crash tests and the Frontier/Equator, as well as the Ranger and the Tacoma all had “good” ratings. The Chevrolet Colorado rated “poor” because of the lack of additional airbags to protect the driver’s chest and pelvis, as well as its poor structure. IIHS also reported that the dummy’s head almost moved around the standard curtain side airbag upon impact during testing. The Dakota had a different problem altogether. Its optional curtain side airbags failed to deploy upon impact.

In addition, the 2010 Dakota does not have standard side airbags unlike all the vehicles in its class when an agreement among 15 manufacturers was made way back in 2003 to make safety improvements that would reduce the risk for people in front and side crashes involving larger and heavier SUVs and pickup trucks. While the agreement was made specifying performance criteria instead of features, side airbags is an important feature to make this happen.

"Chrysler is the only manufacturer we know of that isn't living up to the spirit of the 2003 agreement," said Zuby.

Chrysler engineers identified a problem with the computer program algorithm which determines when the airbags should be fired and are currently working on a fix. The IIHS will be conducting another test on the Dakota and will publish the results soon after.

But it seems that most reports stated that Tacoma is a better truck "better buy", such as Consumer report etc. Why do you think??

That report says three things to me:
1) Wear your seat belt
2) Don't flip your truck
3) Don't believe that everything coming from the insurance lobby that they say is bad, is bad

According to the report, Nissan Frontier and Ford Ranger are having better quality roofs which is tested by IIHS. The small pickup trucks are either made for small transports or small sort of business transportation, where actually there is no need of heavy vehicles. In these kinda vehicle, it needs to put the load in the truck container as well as sometimes the roof is again loaded, so the roof must be strong enough to carry the loading.
