Primarily based on the superior structure of Mannequin S and Mannequin X, which had been beforehand discovered by the Nationwide Freeway Site visitors Security Administration (NHTSA) to have the bottom and second lowest chances of damage of all vehicles ever examined, we engineered Mannequin three to be the most secure automobile ever constructed. Now, not solely has Mannequin three achieved an ideal 5-star security ranking in each class and sub-category, however NHTSA’s assessments additionally present that it has the bottom chance of damage of all vehicles the security company has ever examined.
NHTSA examined Mannequin three Lengthy Vary Rear-Wheel Drive as a part of its New Automobile Evaluation Program, a collection of crash assessments used to calculate the probability of great bodily damage for entrance, facet and rollover crashes. The company’s information exhibits that automobile occupants are much less prone to get critically damage in some of these crashes when in a Mannequin three than in another automobile. NHTSA’s earlier assessments of Mannequin S and Mannequin X nonetheless maintain the file for the second and third lowest chances of damage, making Tesla autos the most effective ever rated by NHTSA. We anticipate related outcomes for different Mannequin three variants, together with our dual-motor autos, when they’re rated.
What makes Mannequin three protected? Along with its close to 50/50 weight distribution, Mannequin three was additionally designed with a particularly low polar second of inertia, which implies that its heaviest parts are situated nearer to the automobile’s middle of gravity. Despite the fact that Mannequin three has no engine, its efficiency is just like what’s described as a “mid-engine automobile” as a consequence of its centered battery pack (the heaviest part of the automobile) and the truth that Mannequin three’s rear motor is positioned barely in entrance of the rear axle relatively than behind it. Not solely does this structure add to the general agility and dealing with of the automobile, it additionally improves the aptitude of stability management by minimizing rotational kinetic power.
Like Mannequin S and Mannequin X, Mannequin three advantages from its all-electric structure and powertrain design, which consists of a powerful, inflexible passenger compartment, fortified battery pack, and total low middle of gravity. These security fundamentals assist to stop intrusion into the cabin and battery modules, scale back rollover threat, and distribute crash forces systematically away from the cabin – all whereas offering the muse for our superior entrance crumple zone that’s optimized to soak up power and crush extra effectively. Right here, you’ll be able to see how the orange inner combustion engine block is thrust in the direction of the cabin throughout a frontal affect check:
We additionally added state-of-the-art options and new improvements in crash construction design, restraints and airbags, and battery security to the core of Mannequin three’s design:
In frontal crashes, Mannequin three’s environment friendly entrance crumple zone fastidiously controls the deceleration of occupants, whereas its superior restraint system enhances this with pre-tensioners and load-limiters that preserve occupants safely in place. Specifically designed passenger airbags are formed to guard an occupant’s head in angled or offset crashes, and lively vents dynamically regulate the interior stress of the frontal airbags to optimize safety based mostly on the distinctive traits of the crash. Entrance and knee airbags and a collapsible steering column work to additional scale back damage, all contributing to Mannequin three’s 5-star ranking in frontal affect.
In pole affect crashes, during which a slender obstruction impacts the automobile between the principle crash rails, energy-absorbing lateral and diagonal beam constructions work to mitigate the affect. This features a high-strength aluminum bumper beam, a sway bar positioned low and ahead within the entrance of the automobile, cross-members on the entrance of the metal subframe which are related to the principle crash rails, and extra diagonal beams within the subframe that distribute power again to the crash rails once they aren’t straight impacted. An ultra-high power martensitic metal beam can be connected to the highest of the entrance suspension to additional soak up crash power from extreme impacts, and the rear a part of the subframe is formed like a “U” and buckles down when impacted. These constructions proceed to be efficient even when a entrance motor is added for Mannequin three Twin-Motor All-Wheel Drive, as a consequence of the truth that the subframe is designed to drag the nostril of the motor down and out of the way in which.
Mannequin three additionally has the bottom intrusion from facet pole affect of any automobile examined by NHTSA. In contrast to frontal crashes, there may be little room for crumple zone in a facet affect, so we patented our personal pillar constructions and facet sills to soak up as a lot power as doable in a really brief distance. These constructions work alongside the automobile’s inflexible physique and fortified battery structure to additional scale back and forestall compartment intrusion. With much less intrusion into the cabin, our facet airbags have more room to inflate and cushion the occupants inside.
Rollover accidents are a major contributor to accidents and deaths on U.S. roads. Tesla’s automobile structure is essentially designed to have a really low middle of gravity, which is achieved by inserting the heavy battery pack and electrical motors as near the bottom as doable. Within the occasion rollover does happen, our inner assessments present that the Mannequin three physique construction can stand up to roof-crush masses equal to greater than 4 instances its personal weight and with little or no structural deformation. NHTSA’s requirements solely require that vehicles stand up to a great deal of thrice their very own weight.
Many firms attempt to construct vehicles that carry out properly in crash assessments, and each automobile firm claims their autos are protected. However when a crash occurs in actual life, these check outcomes present that in case you are driving a Tesla, you’ve got the most effective probability of avoiding severe damage.
