There is no doubt that Tesla is one of the most popular electric car brands. The company practically helped create this particular segment of the car market. Because of this popularity, many are interested in what powers the most popular electric car model in the world. Recently, Tesla engineers revealed some of the Model 3's secrets.

Here are some few interesting points:

Car Safety System and Suspension

Tesla regularly flaunts the perfect 5-Star Safety Rating of the Model 3 awarded by a number of safety regulatory agencies including the National Highway Traffic Safety Administration, the European New Car Assessment Program, and the Australasian New Car Assessment Program.

Tesla claims that the Model 3 was designed with safety as its most important priority. According to Tesla engineers, the Model 3's front suspension features a unique design. They revealed that these suspensions are designed in a way to provide maximum protection when it comes to frontal collisions.

The suspensions feature several links that are designed to break when damaged due to a collision. By incorporating this mechanism, the Model 3's front wheels will continue to rotate in the event that the suspension is damaged.

Tesla Model 3 suspensions are designed using various concepts from NASA. The Tesla Model 3's suspension is widely considered as a major breakthrough. Several teardown experts and automotive veterans have praised the car's suspension technology.

Tesla has also extended this space-age technology into the development of the Model 3's tires.


Based on the latest revelation from Tesla, the Model 3's braking system is unique in its own way. The electric car features expensive four-pot brake calipers installed on its front wheels. This is a great shift from the traditional single-piston sliding mechanism. By incorporating this particular braking system, the Tesla Model 3 has a great brake pedal response. Tesla's breakthrough eventually leads the company to develop its own piston seals.

Tesla founder and chief executive officer Elon Musk have, on several occasions, have said that brake pads installed in all Tesla electric cars will last a lifetime. Recently, Tesla engineers confirmed Musk's claim is noting that the Model 3's discs and brake pads are specifically engineered to last for a rated 150,000 miles. Tesla engineers claim that they were able to achieve through its regenerative braking system. It is a system that allows the car to slow down without completely using its physical brakes.
