For example, I am going to buy a new car in the next 2 years, so looking a bit, and two cars I might be choosing behind would be the:
Peugeot 3008/5008, seen as a SUV in the Netherlands: 67% Pedestrian Euro NCAP score: https://www.euroncap.com/en/results/peugeot/3008/5008/26581
Peugeot 208, smaller car, same brand, same year: 56% https://www.euroncap.com/en/results/peugeot/208/38543
Or the original posters BMW X3: 70% https://www.euroncap.com/en/results/bmw/x3-/-x4/33285
Otoh, the BMW 3 series: 87% https://www.euroncap.com/en/results/bmw/3-series/38531
Full electric BMW i3: 57% https://www.euroncap.com/en/results/bmw/i3/8863
So what I am trying to say is: yes, "SUV" in general are likely to be worse for pedestrians, but there is so much variability, that "picking a SUV" doesn't mean much about safety.
