IIHS Crash Test Tour

A Deep Dive into the IIHS Vehicle Research Center

On a foggy October morning, a group of Virginia Tech engineering students, organized by the growing Virginia Tech SAE Chapter (commonly known as the Society of Automotive Engineers), traded the familiar sights of Blacksburg for the sprawling campus of the Insurance Institute for Highway Safety (IIHS) Vehicle Research Center in Ruckersville, Virginia. We were hosted by Luke Riexinger, a former Virginia Tech professor now serving as a crash test engineer at the facility. His transition from the classrooms of Blacksburg to the high-stakes laboratory of the IIHS provided a unique bridge between academic theory and the brutal reality of kinetic energy.

The IIHS is an independent, nonprofit scientific and educational organization dedicated to reducing deaths, injuries, and property damage from motor vehicle crashes nationally. For student engineers, this facility represents the pinnacle of applied biomechanics and structural analysis. Our tour covered the full spectrum of modern safety evaluation, from the nuances of dummy calibration to the high-tech sensors used in autonomous driving safeguards, culminating in the live destruction of a 2026 Hyundai Palisade. 

Meeting the Dummies

Our tour began in the Dummy Lab, a space that feels like part medical clinic and part robotics workshop. As our guide explained, crash test dummies are the most critical tools in an IIHS engineer’s arsenal. They are not merely plastic mannequins; they are sophisticated instruments of data collection consisting of steel frames, vinyl skin, and an intriguingly complex nervous system of sensors that cover nearly every inch of each dummy.

We were introduced to several specialized models:

Hybrid III Series

The workhorse for front crash testing. The 50th percentile male (standing 5’9” and weighing 170 pounds).

SID-IIs

Specifically designed for side-impact crashes. This dummy represents a 5th percentile female or a 12- or 13-year-old child. Its smaller stature is vital for evaluating side protection, as smaller occupants are more susceptible to head injuries from intruding vehicles.

BioRID-II

A marvel of Swedish engineering used for rear-impact tests. Unlike the stiffer Hybrid III, the BioRID-II features a sophisticated “spine” with 24 articulated vertebrae, allowing engineers to measure the subtle neck movements that lead to whiplash.

Technicians in this lab conduct rigorous calibrations before and after every test. As the signage in the lab aptly notes, “This lab is where dummies begin and end every crash test cycle.”

Evaluating Structural Integrity

Moving into the main hall, we explored the evolution of the crash tests themselves. The engineer explained that the IIHS focuses on “offset” crashes rather than full-width hits. In an offset crash, only a portion of the vehicle’s front end strikes a barrier, which is far more demanding on the vehicle’s structural safety cage.

We observed the difference between Moderate Overlap (40% of the front strikes a barrier) and the more grueling Small Overlap (25%). The latter was introduced in 2012 to address a common scenario where vehicles clip a tree or utility pole, often bypassing the primary energy-absorbing structures of the car.

The side crash testing area showcased a recent shift in the industry. Since 2021, the IIHS has used a heavier, 4,200-pound striking rig traveling at 37 mph. This updated test delivers 82% more crash energy than the original test established in 2003. Seeing the deformed aluminum honeycomb surface of the striking rig provided a visceral sense of the forces that automotive engineers must manage.

Technology and Prevention

Modern safety engineering is as much about avoiding crashes as it is about surviving it. We spent time at the Headlight Testing station, where engineers measure the reach of low and high beams straightaway and curves. It was surprising to learn that vehicles with good rated headlights have 19% fewer night-time single-vehicle crashes than those with poor ratings.

The tour also delved into the world of Active Safety. The from driver assistance to automation exhibit detailed the requirements for Level 2 automation. For a system to earn a good rating from the IIHS, it must include robust safeguards by monitoring the driver’s gaze and hand position, providing multiple types of escalating alerts, and ensuring that automation cannot be engaged if a seat belt is unbuckled.

The 2026 Hyundai Palisade Live Test

The climax of the visit took us to the viewing gallery of the crash hall. The atmosphere was clinical and tense. A brand-new 2026 Hyundai Palisade was positioned at the end of the runway, tethered to a cable system capable of pulling it at precise speeds.

Once everyone was safely behind a barrier or on the overlook above the test floor, the engineer gave the signal, and the car was propelled down the track. The sound of the impact, a deafening, metallic crunch followed by the hiss of deploying airbags was instantaneous. In less than a second, months of engineering design were put to the ultimate test. As the dust settled and the high-speed cameras finished their cycles, the technicians moved in to measure the intrusion into the occupant compartment, and to download the data recorded by the sensors in the dummies and car.

Reflections and Future Horizons

For us Virginia Tech students, the experience was a powerful reminder of why we study statics, dynamics, and materials science. Seeing a former professor apply these principles to save lives on a global scale was incredibly inspiring. The IIHS continues to push the industry forward, recently adding roof strength tests that require a vehicle’s roof to withstand four times its own weight to prevent occupant ejection during rollovers. As the automotive industry shifts toward electric vehicles and higher levels of autonomy, the challenges for crash engineers will only grow. Heavier battery packs and new seating configurations will require new dummy models and updated testing rigs, however, the IIHS will be right there to tackle those burgeoning engineering challenges.
