Tesla says Model 3 has lowest probability of injury of all cars tested

Previously, the National Highway Traffic Safety Administration (NHTSA) tested the Model S and Model X and found it to have the lowest and second lowest probabilities of vehicular injury respectively. Currently, based on the two models’ advanced architecture, Model 3 was engineered by Tesla to build the safest car which has achieved a 5-star rating in the new car assessment program. 

The test included a series of crash tests to know the measure of the probability of bodily injuries for rollover, side and front crashes using the new assessment program. 

In such crashes, passengers riding the Model 3 are less likely to acquire a serious injury compared to those riding other cars. Tesla’s Model 3 was crowned to have the lowest probability of injury ever tested by NHTSA.

Tesla vehicles are worth the title of being best-rated by NHTSA as their Model S and Model X are still on the second and third lowest probabilities of injury ever tested.

Model 3’s safety secret

The secret behind the safety of this model all boils down to how it was designed. Its heaviest components are placed to the car’s center of gravity. The model does not use an engine which makes the centered battery pack as the heaviest component of this car. This allows it to perform as a “mid-engine car” which means the motor is placed in front of the rear axle instead of behind it.

This design improves the car’s overall agility and stability control by making rotational kinetic energy minimized. In addition to this, the model boasts of its strong passenger compartment, fortified battery pack and a low center of gravity all of which contributes to the prevention of rollover risks, distribution of the forces away from the cabin systematically. Its front crumple zone is also optimized to absorb energy and efficiently crush.

New innovations for crash are added such as airbags, restraints and battery safety.

Frontal Crashes

Model 3’s front crumple zone keeps the passengers safe by controlling their deceleration complemented by pre-tensioners and load-limiters. Airbags are also specially shaped to protect the passenger’s head whether in offset crashes or angled crashes. Based on the kind of crash, the front bags’ internal pressure is adjusted dynamically by the active vents. To further lessen possible injury, knee airbags and collapsible steering column are added.

Pole Impact Crashes

Lateral and diagonal beam structures which absorb energy works to alleviate pole impact crashes. The model has high-strength aluminum bumper beam, a steel subframe that is connected to the main crash rails, a sway bar in front of the car and additional beams which distribute the absorbed energy back to the crash rails.

Attached to the top-front of the suspension is an ultra-high martensitic steel beam to absorb crash energy from severe impacts. The subframe’s rear part is U-shaped and automatically buckles down in the presence of an impact.

Side Pole Impact Crashes

Compared to frontal crashes, in a side impact, there is a little room for crumple zone. Tesla then patented their own pillar structures and sills of the side that it may absorb crash energies as much as possible even in a short distance. Compartment intrusion is less likely due to its rigid design allowing the airbags to use more space to inflate and leaving the passengers well cushioned.

Rollover Crashes

Accidents that led to deaths and injuries on the US roads are highly contributed by rollover accidents. With Model 3’s low polar moment of inertia (where heaviest components are placed in the center of gravity), it can endure roof-crush loads up to 4 times its own weight with little structural deformation in an event of a rollover crash. This is a fact worthy of praise as NHTSA necessitate cars to withstand loads up to 3 times their own weight.
Among all of the car companies that claim to be safe, Tesla shows actual results which are very well supported by NHTSA.
