IIHS crash tests show outstanding results for the Tesla Model Y, which in fact turns out to be slightly safer than Model 3.
The IIHS (Insurance Institute for Highway Safety) has just revealed the results of the safety crash tests carried out with the Tesla Model Y. I really think it is important to mention that, as they state on their website, the IIHS is an "…independent, nonprofit scientific and educational organization dedicated to reducing deaths, injuries and property damage from motor vehicle crashes through research and evaluation and through education of consumers, policymakers and safety professionals.". The Tesla Model Y, like almost all other electric models of the brand, basically got the highest rating in these tests; but in addition to that there is an extra surprise: when looking at the results in detail, the Model Y turns out to be even safer than the Model 3.
In most of the categories in which the IIHS performs crash tests, the Tesla Model Y obtained better marks than the Model 3, especially in those related to injuries that the driver might suffer after an accident. These results show that, not surprisingly, the entire line of Tesla models (S, 3, X and Y) are right at the top of the ranking of the safest vehicles in the world.
The advances introduced in the design of the Tesla Model Y, both in the body and in the structural design, allow the SUV to respond better than the Model 3 in an accident. This progress is most noticeable in frontal crash tests performed on the driver's side, which simulate a collision where it would primarily affect the wheel area rather than the central deformation area of the bonnet.
The Model Y basically redirected the warp energy away from the passenger compartment during the crash tests. Instead of absorbing the impact through the front crumple zone itself, the compartment is moved away from the point of collision. While in the Model 3 the crash penetration reached 8,2 inches (21 cm) in the space corresponding to the feet, in the Model Y it was reduced to only 0,3 inches (1 cm). This is a very important achievement for Tesla's safety engineering team, by using a continuous improvement methodology both on the production of the floor/battery and in software development.
Additionally the Model Y outperformed Model 3 on the "head injury" category: 22 points versus 88 on this test, where a total of 250 points marks the borderline for concussion results.
The frontal crash test against a fixed barrier, displaced 10% of its center line, at an 18 mph (64 km/h) speed, basically evaluates the safety of the frontal deformation zone of the car. In this case the Model Y also fared better than the Model 3. While the Model Y's windshield cracked completely, the SUV's height and shock-absorbing mechanism kept it intact. As in the previous test, the Model Y also outperformed the Model 3 in the head injury category.
The Roof Strength is the only test where the Model 3 outperformed the Model Y, due to the fact that the Model 3 has a shorter roof line, on one hand; and on the other hand it also has a high-strength steel crossbar that joins the two B-pillars, which is not featured in the Model Y.
