The Tesla Model 3 has the Lowest Probability of Injury of Any Vehicle Ever Tested

NHTSA (National Highway Traffic Safety Administration) has released its probability of injury stats for the Tesla Model 3 and it achieved the lowest probabilities of injury of any vehicle ever tested by the agency. That’s pretty impressive and arguably makes the Model 3 the safest car on the road. This comes just a few weeks after NHTSA gave a five-star safety rating to the Model 3.

The vehicle achieved five-star ratings in every category, which is great but not unprecedented. Other cars like the Volvo S60 have also scored five stars in all categories. As far as the NHTSA’s ratings are concerned the S60 stands equal to the Tesla Model 3 in terms of safety.

But the star rating doesn’t tell the whole story.

Tesla pulled the data from NHTSA and came to the conclusion that the Model 3 Long Range Rear-Wheel Drive has achieved the lowest probability of injury of any vehicle ever tested:

“NHTSA tested Model 3 Long Range Rear-Wheel Drive as part of its New Car Assessment Program, a series of crash tests used to calculate the likelihood of serious bodily injury for front, side and rollover crashes. The agency’s data shows that vehicle occupants are less likely to get seriously hurt in these types of crashes when in a Model 3 than in any other car. NHTSA’s previous tests of Model S and Model X still hold the record for the second and third lowest probabilities of injury, making Tesla vehicles the best ever rated by NHTSA. We expect similar results for other Model 3 variants, including our dual-motor vehicles, when they are rated.”

It beats the Model S and Model X, which are now second and third. The chart below compares the three to the top 50 vehicles over the past 7 years:

Tesla further explained how the Model 3 achieved this level of safety:

“In addition to its near 50/50 weight distribution, Model 3 was also designed with an extremely low polar moment of inertia, which means that its heaviest components are located closer to the car’s center of gravity. Even though Model 3 has no engine, its performance is similar to what’s described as a “mid-engine car” due to its centered battery pack (the heaviest component of the car) and the fact that Model 3’s rear motor is placed slightly in front of the rear axle rather than behind it. Not only does this architecture add to the overall agility and handling of the car, it also improves the capability of stability control by minimizing rotational kinetic energy.”

They also included a few videos of comparisons with other vehicles in the same segments and specific types of crashes:

The imagery is pretty clear. Tesla’s electric vehicle architecture helps distribute crash forces away from the cabin while the Audi A4’s motor gets shoved toward the passenger compartment.

Airbags

We also added state of the art features and new innovations in crash structure design, restraints and airbags, and battery safety to the core of Model 3’s design:

In frontal crashes, Model 3’s efficient front crumple zone carefully controls the deceleration of occupants, while its advanced restraint system complements this with pre-tensioners and load-limiters that keep occupants safely in place. Specially designed passenger airbags are shaped to protect an occupant’s head in angled or offset crashes, and active vents dynamically adjust the internal pressure of the frontal airbags to optimize protection based on the unique characteristics of the crash. Front and knee airbags and a collapsible steering column work to further reduce injury, all contributing to Model 3’s 5-star rating in frontal impact.

Pole Impact

In pole impact crashes, in which a narrow obstruction impacts the car between the main crash rails, energy-absorbing lateral and diagonal beam structures work to mitigate the impact. This includes a high-strength aluminum bumper beam, a sway bar placed low and forward in the front of the car, cross-members at the front of the steel subframe that are connected to the main crash rails, and additional diagonal beams in the subframe that distribute energy back to the crash rails when they aren’t directly impacted. An ultra-high strength martensitic steel beam is also attached to the top of the front suspension to further absorb crash energy from severe impacts, and the rear part of the subframe is shaped like a “U” and buckles down when impacted. These structures continue to be effective even when a front motor is added for Model 3 Dual-Motor All-Wheel Drive, due to the fact that the subframe is designed to pull the nose of the motor down and out of the way.

Side pole impact

Model 3 also has the lowest intrusion from side pole impact of any vehicle tested by NHTSA. Unlike frontal crashes, there is little room for crumple zone in a side impact, so we patented our own pillar structures and side sills to absorb as much energy as possible in a very short distance. These structures work alongside the vehicle’s rigid body and fortified battery architecture to further reduce and prevent compartment intrusion. With less intrusion into the cabin, our side airbags have more space to inflate and cushion the occupants inside.

Rollover

Rollover accidents are a significant contributor to injuries and deaths on U.S. roads. Tesla’s vehicle architecture is fundamentally designed to have a very low center of gravity, which is accomplished by placing the heavy battery pack and electric motors as close to the ground as possible. In the event that a rollover does occur, our internal tests show that the Model 3 body structure can withstand roof-crush loads equivalent to more than four times its own weight and with very little structural deformation. NHTSA’s standards only require that cars withstand loads of three times their own weight.

Definitely raises some questions about those teardown videos with the experts claiming Tesla built the car wrong and used too much steel in the wrong places.
