Special Report: On Location as the IIHS Crashes a 2008 Vue
November 13, 2007

Safety has always been one of the hallmarks of Saturn design. From their spaceframe constructed cars in the 1990s, to its latest reinforced steel unibody models of today, Saturn takes pride in engineering vehicle structures that protect passengers in all sorts of crashes. I've always been fascinated by the survivor stories that Saturn owners have shared with me over the years, so when the Insurance Institute for Highway Safety (IIHS) invited SaturnFans.com for a special opportunity to watch as they crash tested an all-new 2008 Saturn Vue – live and in person – I jumped at the chance to see how the vehicle would perform.

If you're not familiar, the IIHS is an independent, nonprofit organization whose mission is dedicated to reducing deaths, injuries, and property damage through scientific research and education. The Institute operates a state-of-the-art crash test facility, called the Vehicle Research Center (VRC), in central Virginia. Like the federally funded National Highway Traffic and Safety Administration (NHTSA), the IIHS spends a lot of time crashing cars and analyzing the resulting data. While the goals of the two organizations are similar, the the IIHS' testing criteria and evaluating parameters are much more stringent. The IIHS routinely performs its crash tests at faster speeds and under more extreme conditions than the NHTSA.

My wife and I traveled to the VRC last week to watch the Institute conduct a side-impact test on the Vue. Much like the former Saturn plant in Tennessee, the Institute's crash center is nestled among fields and rolling hills. Our stay at the VRC included a personal tour of the sprawling VRC complex. This is where the Institute conducts its frontal offset, side-impact, whiplash, and bumper tests. This particular crash was going to test how well the Vue protects its passengers in a side-impact collision. You probably have seen the center featured in Dateline 'Consumer Alert' stories that, until a couple years ago, aired regularly on the NBC television network.

The VRC is divided into seven distinct areas:

  1. Lobby, office, and conference rooms. Inside the lobby area rests two wrecked Chrysler Lebaron convertibles. According to the IIHS, these cars were involved in the first highway accident between two vehicles equipped with driver side airbags. Ironically, this accident happened on a road just a few miles from this facility many years ago.

  2. A display hall where IIHS features vehicles from recent and significant crashes. Cars that have gone through their side-impact test procedure have their doors removed afterwards so that their frame and substructure can be better analyzed. IIHS staff has organized the cars and documented their crashes by placing informative placards and backdrop displays in a way that let's each vehicle tell a story.

  3. A vehicle garage where IIHS technicians prep vehicles for tests by draining the vehicle's petroleum-based fluids, replacing them with non-flamible liquids. They also mount sensors, electronics, and video equipment onto a car. I was surprised to see how much gear needs to be attached to or placed in the car to capture crash data. While the actual side-impact crash is over in a matter of seconds, it takes about two days of prep work to setup a vehicle. The test vehicle spends about half of that time in the garage area up on lifts.

  4. The 21,600 square foot crash hall is the focal point for three runways which allow the IIHS to accommodate a variety of tests. The rigid and moving deformable barriers (used in the frontal offset and side-impact IIHS tests, respectively) are also stored here. Both barriers feature a face made of an aluminum honeycomb. One interesting bit of trivia about the rigid concrete barrier: when it needs to be moved, the barrier can be raised off the floor on a cushion of air like a hovercraft, enabling it to be pushed into and out of position by only a few people.

  5. A crash simulation sled that simulates how well a vehicle's rear crash protection and seat head restraints prevent whiplash. Seats are mounted on a steel flatbed sled that rides on two fixed rails. The sled is moved, or rather suddenly jolted, by a giant horizontal cylinder that slams into the sled to simulate a rear crash. According to the IIHS website, this "recreates the forces on occupants inside vehicles during real-world crashes."

  6. The crash test dummy family room. Several different size dummies "live" in this climate controlled area of the VRC. Each dummy includes between 25 to 40 sensors that record the forces on various parts of the body. The dummies are calibrated for each specific test before they are positioned in vehicles.

  7. A photo studio where "before" and "after" pictures are taken for IIHS reports and website.
The IIHS side-impact test we that were about to see is one of the most challenging crash tests a vehicle can be put through. According to the IIHS, "51% of driver deaths in recent model cars during 2000-01 occurred in side impacts, up from 31% in 1980-81. During the same time, the proportion of deaths in frontal impacts declined from 61% to 43%." This increase in fatalities is largely due to a greater percentage of trucks and sport-utilities on the road today.

As a result, the IIHS developed a 3300 pound moving deformable barrier with a front end shaped to simulate the typical pickup or SUV. The IIHS barrier is taller than the more car-like barrier used by the NHTSA. During the test, the barrier travels at 31 mph into the driver's side of the test vehicle. Due to all the vehicle and barrier preparation involved, only one car can be put through the side-impact test per day. The Institute can conduct as many as two frontal offset tests per day.



On the day of the test, two "SID-IIs" dummies, representing a petite female or a 12-year-old child are placed in the test vehicle. The IIHS uses smaller dummies for the side-impact test, because unlike taller drivers who slide their seats back and are protected by the vehicle's B-pillar, shorter drivers move their seats forward towards the steering wheel, positioning them in the middle of the driver's door where they are most vulnerable in a crash. Once situated in the vehicle, the IIHS uses different color face paints on the dummy's head and arms, so that any contact during the crash the dummy might have with the airbags, interior trim, or even the movable barrier is documented (the latter was tragically a common occurrence before side curtain airbags became widely available).

The IIHS typically invites vehicle manufacturers to the VRC on test day, and today was no different. Armed with tape measures and cameras, representatives from General Motors were on hand to validate Institute's test setup and procedures. Photos were taken and measurements were checked and double-checked to make sure the vehicle was ready and the dummies were in position for the test. Consistency is key for valid results.

We finished a very thorough tour of the VSC about 20 minutes before the test was scheduled to start. After taking a few final pictures in the display hall (I took more than 350 pictures that day), we made our way to the crash hall, up onto a raised platform above the runway that was going to be used for this test. We waited a few moments for the countdown for the test to start. Once it begins, the end comes quickly. A brand new vehicle and nearly two days worth of work are destroyed in a matter of seconds.



Moments after the test is complete, a team of red-shirted IIHS engineers swarm the test vehicle and movable barrier. While some information is transmitted wirelessly to IIHS computers during the test, other information is downloaded by PCs and test equipment that are carted over to the vehicle after the crash.

So how did the Vue perform? Unfortunately, I can't say just yet. One of the conditions of being able to watch and write about the test was that I'm not allowed to talk about its probable score or how it protected the dummies until the IIHS publishes its analysis. Saturn is reportedly hoping for a high score (to match the IIHS' already published 'good' offset frontal ratings for the new Vue), so that it will be named one of the Institute's Top Picks. Official results should be announced later this week.

It would be remiss of me to close without a thanking the IIHS for the invitation to tour their facility and watch as they tested one of Saturn's most important new vehicles. We left the VRC with a greater understanding and better appreciation for the research and development required to engineer vehicle safety systems. The IIHS folks we interacted with at the center were all extremely friendly, offering to explain any and all aspects of their crash test process. There was genuine a sense among those we met that the work they do everyday saves lives and impacts vehicle design for years to come. And isn't that what its all about?

Stay tuned to SaturnFans.com for a follow-up report once the IIHS releases the Vue's crash results. In the mean time, take some time to browse the IIHS Vue photo and multimedia gallery.
