Small Overlap Test

IIHS has tested the 2014 Jeep Grand Cherokee in small overlap crash test.. This test is very tough, and I think it didn't do too bad..

Models built after January 2013, were modified to improve occupant protection in small overlap frontal crashes.



INFO FROM IIHS;

Structure

The driver space was not maintained well, with maximum intrusion of the lower interior of 22 cm at the brake pedal. The parking brake pedal was pushed back toward the driver 21 cm. Upper interior intrusion measured 13-15 cm at the hinge pillar and instrument panel.


Injury measures

Measures from the dummy indicate that injuries to the left lower leg would be possible in a crash of this severity. The risk of significant injuries to other body regions is low.


Restraints and dummy kinematics

The dummy’s movement was reasonably well controlled. The dummy’s head remained largely in contact with the frontal airbag, but its head still moved toward the intruding A-pillar because the seat belt allowed excessive forward excursion of the dummy's head and torso. The side curtain airbag deployed but does not have sufficient forward coverage to protect the head from contact with forward side structure and outside objects. The side torso airbag deployed.

Thanks for posting this. That knee airbag that they added in the middle of the model year is probably why it ended up with "marginal" and not poor. Having your head completely miss the airbags is bad enough. To then have your legs broken as well is just awful.

When researching my wife's new car last year and looking at these small overlap collision results, what I came away with was: if you're going to hit something head on, and if you don't have enough time to swerve the nose completely out of the way, it looks better to hit it square on versus swerving partially and having your head hit the A pillar.

Re: Small Overlap Test

This is a very tough test, but I'm glad they are doing it these days...it emulates a type of crash that is very, very common, both with other vehicles and immovable objects, like utility poles.

While there were some vehicles that did better than JGC in the recently published tests, there really were not "stellar" performances from anyone. Tough test, for sure!

I agree there wasn't stellar performances from any car manufacture. Car manufactures were not prepared for this type of test and didn't design their cars for this type of crash. The only manufacture that really shown was Volvo.. From the outset Volvo has designed their cars with this type of crash in mind.. And it shows in the results.. Even the very old and dated XC-90 came off a lot better than most if not all newer mid-sized SUVs.

This type of test is brilliant, manufactures were just caught off guard. We're going to see the next generation of vehicles even more safer, and designed with this test in mind. I really want them to test the new Cherokee to see how that performs, maybe a lot better than the GC.

Overall I think the GC didn't too bad tbh. It gained only marginal rating, but the dummy didn't suffer any life threatening injuries.. And the structure didn't deform that bad. The steering column was very stable with very little or no movement and the dummy's head made direct contact with the front airbag..

On the flip side, the head airbag on the GC is a cheap design, as it doesn't extent along the full width of of the side windows, hence the dummies head sliding off the airbag at the end. And that parking brake!!.. Well see for yourself!

Re: Small Overlap Test

I think that all things being equal, then safety sells. The small overlap test does matter to potential new buyers.

Re: Small Overlap Test

I'm probably a minority in this regard but I was ready to purchase '14 JGC until I saw the IIHS small overlap test results. I had trim level, options, engine, color, and dealer picked out, and I liked everything about the JGC. After test driving several competitors models I was certain JGC was the right choice. However, I did some last minute research on safety because I noticed JGC was no longer advertised as an IIHS top safety pick, and this is when I saw the small overlap test results. How can I pay 54K drive-out for a vehicle that fails an IIHS crash test? I know that some vehicles did worse, some are yet to be tested, and it is a difficult test. However, small overlap is a common crash scenario and GM and Subaru both have crossovers that received "good" in this test and I believe designing for safety earned them this rating. I hope Chrysler reacts for the JGC '15 model year but I doubt they will.

Re: Small Overlap Test

Colo', these safety tests/ratings are moving targets and it's noteworthy that very few vehicles do "really well" on this new small overlap challenge in their present forms. Even a "good" rating isn't the best and that's telling, too. This particular scenario probably isn't trivial to address by any car manufacturer but I have no doubt they will do so as their vehicle platforms evolve. Don't expect major changes from anyone on this test on minor model year changes...it's likely going to have to happen in "next generation" models.
