GM SUVs get top crash scores, Honda Pilot at bottom

General Motors' aging Chevrolet Equinox and GMC Terrain SUVs won top ratings in the most-recent crash tests of SUVs by the Insurance Institute for Highway Safety. Honda Pilot was in the bottom slot.

Both the GM models were awarded the trade group's highest rank, Top Safety Pick +. The "+" means a vehicle not only scored well on other crash tests by the IIHS, but also held up well in the relatively new – and remarkably punishing – "small overlap" test.

Toyota's redesigned Highlander scored lower overall, but high enough to also earn a Top Safety Pick + rating, IIHS had announced in December.

"When it comes to midsize SUVs, General Motors is showing the way forward," IIHS said in its summary of the most recent tests.

Equinox first went on sale in 2004 as a 2005 model. The similar GMC Terrain was added later.

IIHS says the Equinox – and by inference, the Terrain – got "modifications on 2014 models to their front structure and door-hinge pillars." The changes were able to minimize crash forces that reached the passenger compartment in bedeviling "small-overlap" test.

It slams 25% of the vehicle's width, on the driver's side, head-on into a five-foot-tall immovable barrier at 40 mph. It's meant to duplicate crashes where a small portion of the driver's side hits a pole or tree or other obstruction.

What makes it tough: Almost everything that bears the brunt of the crash is outboard of the vehicle's main structure, where energy-absorbing beams and other components normally would lessen the blow to the driver.

IIHS says that "a quarter of the serious injuries and deaths occurring in frontal crashes are in small overlap impacts where just the front corner of a vehicle clips the front of an oncoming car or strikes a tree or pole."

Even in the best-scoring models, that left front portion of the vehicle is shoved back to the dashboard and mangled so badly it's unrecognizable. But in the top models, the major damage stops at the passenger compartment, and airbags cushion the blow to drivers.

The rankings of tested models in the "small-overlap" test, from best to worst:

•Chevrolet Equinox/GMC Terrain•Toyota Highlander•Jeep Grand•Toyota 4Runner•Ford Explorer•Kia Sorento•Mazda CX-9•Honda Pilot

Honda, which usually is able to brag about its crash-test scores, sent a pre-emptive note to diffuse the image hit it could take from the Pilot's bad score. Honda says it "leads the industry in third-party crash test ratings with more vehicles rated Top Safety Pick and Top Safety Pick + by the Insurance Institute for Highway Safety (IIHS) than any other manufacturer."

The damage-control note pointed out that Honda's redesigned models get the latest safety structures, but it didn't say when the Pilot would be redesigned.
