Dramatic new footage shows how star ratings save lives in crashes

Friday, May 29, 2020

Compelling new crash test footage released today by the NZ Transport Agency provides graphic evidence that the choice you make when buying your next used car could be a life and death decision.

The footage shows the results of a controlled offset frontal crash test carried out at a speed of 64km/h between a 1-star safety rated 2010 Hyundai Getz, and a 5-star safety rated 2008 Audi A3. 

These two models were chosen for the test in consultation with the Automobile Association (AA), as both are widely available as used vehicles in New Zealand, within a similar modest price range.

The crash test was carried out earlier this year in the Transport for New South Wales Crashlab facility, as part of the NZTA’s Safe Vehicles Programme, which aims to get more Kiwis into cars with 4- or 5-star safety ratings. The 64km/h head-on crash test simulates a common high-speed crash scenario, where one vehicle drifts over the centre line on an open road.

The contrast in the outcome of the crash for occupants of the two vehicles is stark, with readings taken from the instrumented crash test dummies in each car showing a 77% chance of serious injury for the driver of the 1-star rated vehicle compared with just a 12% chance of serious injury for the driver of the 5-star car.

NZTA NZ senior road safety manager Fabian Marsh says the crash test result provides further evidence of the value of star ratings.

“Checking the safety rating before buying your next car could well save your life. Research shows that vehicle occupants are twice as likely to die or be seriously injured in a crash in a 1- or 2-star rated car than they are in a 5-star rated vehicle, and this latest crash test result backs that up.

“The numbers are clear: the higher the safety rating the more likely you are to avoid serious injury or death in a crash,” Marsh says.

AA principal advisor regulations Mark Stockdale says the results of the test demonstrate why everyone should buy the safest vehicle they can afford.

“These two models are similar in size, they’re both widely available as used vehicles in New Zealand, within a similar price range, but there is a huge difference in the level of protection they provide in a crash,” Stockdale says.

Monash University Accident Research Centre associate director Stuart Newstead reviewed the crash test result for the NZTA, and agrees the results are compelling.

“The results are very clear – the occupant cell of the 1-star collapses, crushing the driver's legs. In the real world this is very likely to lead to a serious injury or death, particularly if the major arteries in the legs were compromised.

“The driver of the 1-star car in this crash would also have suffered a serious neck injury due the level of structural damage. The 5-star car hasn’t had the same level of structural damage. This shows that structural integrity is a key aspect of vehicle safety. It’s not enough to say a vehicle has an airbag so it will be safe. A car is designed as a holistic system of interacting parts and they all need to work together properly to make sure the occupants are protected.”

The graphic shows crash test results for a 5-star rated 2008 Audi A3 compared with a 1-star rated 2010 Hyundai Getz.

Safety ratings indicate the likely performance of your vehicle in a crash, from 1 to 5 stars. Vehicles with 4- and 5-star ratings are the safest. The New Zealand light vehicle fleet currently has a high proportion of 1- and 2-star safety-rated vehicles (41 percent) that provide far less protection to occupants than higher-rated vehicles in the event of a crash.

A national advertising campaign launched in February as part of the Safer Vehicles programme targets people who are in the market to buy a new or used car, encouraging them to make safety a top factor in any vehicle purchasing decision. The campaign directs people to the newly designed and expanded Rightcar website, which now provides safety ratings covering around 95% of vehicles on New Zealand roads.

Marsh says with approximately 800,000 vehicles changing hands in New Zealand each year there is great potential to save lives and prevent serious injuries by encouraging people to buy cars with a good safety rating. A new search filter launched by Trade Me earlier this month, supported by the NZTA, also allows prospective buyers to search for vehicles by their safety rating.

“We all make mistakes when driving, and some crashes are inevitable, but safer vehicles can save lives in crashes. Checking a vehicle’s safety rating before you buy isn’t often high on the list of priorities for many New Zealanders, and we need to see that change.”
