What Volvo's Equal Protection Claim Does and Doesn't Prove

Volvo recently put out a press release saying its research proves Volvo cars protect women and men equally. The research behind it is good. It proves less than the headline says.

The problem Volvo is pointing at is real. The IIHS has found that women face a higher risk of injury in crashes than men. Some of that comes from what people drive, since women have historically been more likely to be in smaller cars and men in pickups and big SUVs, and the type of crash and where you're sitting matter too. But the gap doesn't fully go away when researchers account for all of that, and a lot of the suspicion lands on how cars get tested.

For decades the standard crash dummy has been an average-sized man. The smaller female dummy used in many tests is mostly that same man scaled down, which is a poor stand-in when you're trying to work out what a seat belt or an airbag actually does to a woman's body.

The big electric SUVs

I looked at the published crash results for five large electric SUVs sold in North America. All of them test well, although the tests available differ by model and year.

Four of them carry an IIHS Top Safety Pick+. The fifth, the Tesla Model X, scored 98% for adult protection from Euro NCAP, but that was in 2019 under an older protocol, so it doesn't line up cleanly against the others.

The Volvo EX90 had the strongest recent Euro NCAP result at 92%, with especially good frontal and side-impact scores. The Kia EV9 and Hyundai IONIQ 9 both came in at 84%, and both had chest protection rated marginal in at least one test (for the IONIQ 9 it was a side-pole impact). On the other hand the IONIQ 9 and the Rivian R1S both did well protecting smaller passengers in the rear seat.

None of that tells you which one protects a woman as well as a man.

What the tests can and can't show

The testing has improved a lot in a generation. The IIHS now puts a smaller dummy in the back seat for its updated moderate-overlap frontal test, and Euro NCAP looks at different occupant sizes, seating positions and types of crash. Euro NCAP also reports that several makers, Kia and Hyundai along with Volvo, show similar frontal protection across occupant sizes and seats. So Volvo isn't alone in engineering for different bodies.

Protecting different sizes of dummy in a controlled test is a different thing from equal injury risk for women and men on real roads, though. A smaller dummy isn't female anatomy. And a test with a female dummy in the passenger seat and a male dummy behind the wheel mixes up sex with seating position, so you can't pull the two apart.

Most buyers only ever see the star rating anyway. The readings underneath it, chest compression, neck forces and the rest, are in the technical reports, but they aren't laid out in a way anyone can easily compare across vehicles.

Volvo's paper

Volvo's 2026 technical paper goes past the lab. It uses decades of real crash data on Volvos in Sweden and finds the risk of moderate or worse injury fell for both female and male drivers, with the bigger gains for women. That's solid evidence that engineering can close a gap that has been there for a long time.

But it compares older Volvos to newer Volvos. It doesn't put a current Volvo up against an EV9 or an R1S, and it doesn't show that every Volvo protects everyone equally in every kind of crash. "Proves" is doing a lot of work in that press release.

What buyers can't find out

If you're comparing these vehicles, the questions that matter are fairly basic. Does this one protect a smaller person as well as a larger one? Are women more likely to get a particular kind of injury in it? Has the maker shown equal protection with real injury data, or only in the lab?

Right now none of the ratings answer them, and most of the data needed to do it already exists. The testing bodies record measurements from several dummies in different seats, the manufacturers have their own simulation and crash data, and collision databases go back decades.

I think the IIHS and Euro NCAP are the obvious ones to publish female and male results side by side for each model, in a form a buyer can actually read. Until someone does, a claim like Volvo's is hard for anyone to check against the competition.
