It's called the IIHS small overlap front crash test. Many cars do poorly not for nefarious reasons (and I know you weren't claiming so) simply because it was not really considered before. What happens in many cases is the front wheel detaches and travels up into the passenger compartment, bringing the engine and transmission along as well. Also the A pillar takes a large force, which unlike the intrusion was expected. In many cars that fared well enough even when the front crush box was avoided. What happened is that statisticians at insurance companies noticed an anomaly of accidents causing high medical claims which stood out from other similar speed frontal impacts. To some extent Honda and Volvo in particular already anticipated this more than other manufacturers though.
