Why Tesla's Model X Was The First SUV To Receive A Perfect Crash Test Rating
Опубликовано: 18 янв. 2019 г.SUVs are generally safe, but have a high rollover probability. Tesla was able to overcome this obstacle with their Model X SUV. Here's how they did it.
Narrator: This Tesla Model X refuses to roll over. Unlike most SUVs which tend to roll over with ease, the Model X continues to return to an upright position. Here's why the Model X was the first SUV to receive a perfect crash test rating. When it comes to vehicle safety, size matters. So it's not uncommon for SUVs to be generally safer than your standard sedan. However, they tend to have one big shortcoming. Rollovers.
SUVs are notorious for having a high center of gravity causing them to roll over when put into tight maneuvering situations, or a side impact. Rollovers can result in the partial or full ejection of passengers from the vehicle, increasing the chances of injury or death. In 2016, rollovers happened in one percent of serious crashes in passenger vehicles but accounted for one-third of collision-related deaths.
Over the past three decades, automakers have been able to reduce the frequency of rollovers in vehicles with technology and more stable designs. However, once a serious impact occurs it's just basic physics. A higher center of gravity increases the likelihood of a car tipping or rolling over.
The National Highway Traffic Safety Administration or NHTSA is the only organization that tests rollover resistance. They also test frontal crashes and side impacts from a pole and barrier. After each test, they measure readings from a dummy to determine how much damage a real person is likely to sustain. They use this data to determine a safety rating in each category and an overall safety rating for the vehicle.
Amongst its many luxury features, the Model X hosts active safety technology such as collision avoidance systems and automatic emergency braking. But what sets the Model X apart is its design. Like other Teslas, the Model X has a large, rigid battery pack located on the floor of the vehicle. This gives the Model X a much lower center of gravity than your average SUV. In the event of a collision that would normally cause an SUV to roll over, this would happen instead.
But rollovers are just one aspect of the safety test. Since the Model X is an electric vehicle, there's no need for mechanical components in the hood of the car. This allows for a much larger crumple zone to absorb energy from a frontal crash. It also has specially-made side sills that absorb energy in addition to its rigid side pillars. These features help reduce the force exerted on passengers and increases their protection. But if you don't have $80,000 laying around for a Model X there’s still plenty of SUVs out there with excellent safety ratings.
Опубликовано: 15 февр. 2020 г.Several major automakers are making big bets on electric vehicles. A few vehicles have been released so far, but sales indicate any one of them has failed to make a significant dent in Tesla’s share of the EV market. So, who are they? And how much of a chance do they have?

Описание канала:
Дорогие друзья добро пожаловать на мой канал Prozhektor8kvt, канал мастерская, канал отражающий мою жизнь. Я считаю что нельзя тратить всю жизнь на что то одно. Посвящать всю жизнь одному делу. Жизнь слишком коротка, а то чему надо научится слишком много. Поэтому надо начинать. Начинать прямо сейчас! Смысл этого канала не учить, а вдохновлять, вдохновлять любым доступным способом. Мой способ показывать мою работу. Даже если она не красива. Я не ставлю целью поразить вас качеством работы. Я хочу чтобы вы смотря мои видео говорили. Блин даже если у этого рукожопа получается, у меня получится не хуже. Удачи вам в ваших начинаниях!

How fast will the Tesla Roadster be? How do the Tesla Roadster cold gas thrusters work? How much will the Tesla Roadster weigh? What will the Tesla Roadster's 0-60 be? How about braking distance, or cornering grip? Will the Tesla Roadster be able to fly? Using everything that's been stated about the Tesla Roadster Space X Thruster package, we'll deep dive into how the system works and what sort of performance metrics you can expect to see as a result.
The Tesla Roadster will use an electric air pump, powered by the main battery, to compress air into a composite over-wrapped pressure vessel (COPV). The COPV will deliver highly compressed air (~10,000 PSI) to around 10 cold gas thrusters integrated around the vehicle. This cold gas thrusters will allow for incredible acceleration, braking, cornering, and potentially even the ability to fly.
