NHTSA has recognized the Tesla Model 3 the safest passenger car in the modern car market. In September this year, the US National Highway Traffic Safety Administration awarded the Tesla Model 3 with a maximum 5-Star safety rating based on the results of the crash tests.
This award also means the lowest possibility of injuries to the driver and passengers among all known cars. Actually, NHTSA has titled the Tesla Model 3 the safest car in the world.
What does ‘safe’ mean for NHTSA?
A few models have ever gained 5 Stars in the history of the organization. One of them is the Volvo S60 sedan.
NHTSA checks safety by several parameters. First they assess probability and severity of injuries of the driver and passengers (head, torso, chest, neck, femoral bones) in case of car overturning, frontal and side impacts.
So, according to crash tests, the Tesla Model 3 showed the lowest possibility of getting injured among all cars available on the market today. This figure does not exceed 5.7%, which is much lower than that of any other testee.
How could the Tesla Model achieve this level of safety?
The body’s design and layout played the main role. This is, firstly, about the low center of gravity providing the best protection in case of a rollback. Secondly, even weight distribution along the axles, so that the vehicle’s front and rear parts have the same weight. The moment of inertia minimizes during abrupt braking.
By placing the battery and engine in the center of the Tesla Model 3, the manufacturer has obtained maximum stability of the car. Even during a strong side strike, the electric car shows low rotational power.
Thanks to the rigid architecture of the interior and reinforced battery zone, the energy of the front impact is accumulated far from the driver and passengers, thus preventing injuries.
A similar effect of minimum torsion of the Model 3’s front end is achieved through the use of:
- high-strength aluminum bumper;
- special cross-members of the steel subframe;
- additional diagonal beams in the subframe;
- attaching a martensitic-steel beam to the front suspension’s top.
Thanks to these elements there is a significant absorption of the front impact energy with displacement of the subframe’s rear part not into the cabin, but down.
Another safety factor in the Tesla EV is its patented airbag system for passenger area, as well as a special design of the side racks and thresholds, which are able to absorb the side impact energy.
In case of influence of external forces on the car’s body, the side racks and thresholds are minimally flexed inside the cabin. In this way, they do not pose a danger to the person and keep the interior space for the airbags.
