Cars 3 Official US Teaser Trailer
New cars already smashed the front and rear, side and from above, in a battery of tests that made safer vehicles than ever, but people die in accidents, even in these new cars very safe, so the insurance Institute for Highway safety IIHS devised another way to demolish cars to test a type neglected accident that attracts just the leading edge of a car.
The IIHS is already using an offset frontal crash test, side impact test, a rear impact test, and a roof-crush test to determine the safest prices Not U S government official tests; the National Highway Traffic Safety Administration did but marking an acceptable level or the IIHS tests are necessary to obtain a recommendation of influential consumer reports and boast in ads to be a first security choice, so that car manufacturers take these tests seriously.
The new test is called a small frontal crash test shift Currently, NHTSA made a frontal crash test that effectively rammed a car into a wall at 35 mph to test head on shots This crash test lag before is more realistic because head slightly accident see cars perfectly aligned with each other when they are offset, which is what happens when drivers swerve to avoid the impact, the collision force is concentrated in only the part of the car that hit s.
The IIHS offset frontal crash test spots existing car plow right in a deformable barrier designed to reproduce a collision with another car at 40 mph with the concentrated force of 40 percent of the front end for the new test, that impact strikes just the corner of the car, concentrating all the power on only 25 percent of the front, which focuses all the energy in one part of the car where there is no generally frame structure to absorb the blow, making it a more difficult challenge of safety for new cars.
And because the crash hit the front corner of the car, the vehicle pitches on the side of the impact, the rotation around the point of impact safety systems are designed to protect against direct or front side impact so they can not respond appropriately to this kind of accident where the driver would be thrown to the side, even though there was no direct side impact.
The IIHS has developed this test after studying late model cars that have registered well in its tests, but still suffers fatalities cars are safer than they've never been, but about 10 000 deaths per year involve a frontal collision, according to the IIHS, and about a quarter of these accidents fall into the category of collisions with small shift either other cars or objects such as trees and poles are serious accidents, and our new test reflects that, said the IIHS President Adrian Lund.
Because haven Car peace t been crash tested in exactly that way before, the results were scattershot The Acura TL and Volvo S60 both Volvo achieved good scores, it is already done similar tests, so the S60 was prepared other pillars of security automakers such as Mercedes-Benz dishes didn t so well in the first series of tests, the IIHS saw the door ripped clean the car driver of the Volkswagen CC.
Car manufacturers will begin to develop new cars with this test in mind, but it probably means adding an additional steel armor at the front corners that aggravate weight escalation seen in the news lately automakers talked a lot about cars finding ways for new models weigh less than their predecessors, but increasingly tough crash tests make it so difficult This extra weight has made improving gas mileage a chore even more difficult, but neither automakers or consumers seem willing to trade security for greater efficiency thanks to its lighter weight.
Honda said it is building cars in 2013 with the test in mind; the new agreement could be among the first cars to do, but that doesn t mean other cars are doomed to poor scores until they are completely renovated IIHS said many subtle details may improve models scores existing programming side and curtain airbags deploy during such accidents is one means among 13 luxury entry models tested to date, the side airbags are not deployed in the test because they are primarily for protection against impact side.
In the longer term, automakers are likely to redraw the airbags to protect against this type of accident current side airbags and curtains do not extend very far ahead because they anticipate a T-bone type of the accident pitching the occupant side in these small overlap frontal test, the crash test dummy tends to pitch diagonally to the windshield pillar, falling into a space between front airbags and side.
Seatbelts also change Volkswagen and Mercedes have had poor performance due to their programming waist belts are programmed to have some give in frontal crashes to reduce the loads placed on the chest of the occupant But in the little test overlap, which give opportunity for dummies move too far in a cabin that collapses back a few minor adjustments to belts, bags and software will help a lot of cars to better protect occupants and earn decent evaluations until they receive additional armor body.
Automakers n have no time to adapt to the 2013 model year, the existing rules remain in place for a Top Safety Pick award if cars such as TL and S60 get some kind of star indicating their good performance in Then the new test, for 2014, the new test will be part of the requirements.
The new Crash Test that will change your next car, crash, test, change, frontal crash test.
