Speaking of "Back to the Future", according to the plot, the Doctor drove DMC-12 and took Marty to the next 30 years, that is, 2015, and 37 years have passed since the so-called future in the film today. If we compare the science fiction plot in the movie with today's technology, it seems that we have achieved most of it, which shows the rapid progress of science and technology.
The dmc-12 model in the film has exceeded the million-dollar price so far, and its stainless steel body, gull wing doors and other advanced design concepts have also influenced countless engineers and designers since then, and Elon Musk, as Tesla CEO, is also one of the members who was deeply affected by the movie "Back to the Future".
Aviation-grade materials are not invincible
Why? The reason is that the late Cyberruck is actually very similar to the DMC-12 in terms of design, and the most representative is that both are stainless steel bodies. In fact, the culprit of Cyberruck's repeated ticket jumping is precisely its stainless steel body like a "golden bell cover".
According to the official description, Cybertruck will be made of 30X stainless steel (code 3 series stainless steel) and will be able to resist 9mm bullets, dents, damage and corrosion. The car is like an onshore "Noah's Ark", and the 30X material is also used in SpaceX's Starship super-large aviation spacecraft, which is no wonder why Tesla can say so boldly how strong its own model is.
Although the highlight of the use of aviation-grade stainless steel to make the body can become the capital of the conversation in front of others, it is actually not a good thing. The reason is that stainless steel, although hard and rust-resistant by nature, has weaknesses in its lack of toughness, low temperature fracture, and inelasticity.
The most expensive does not mean the best
Thanks to Starship's aerospace-grade requirements, 30X material has solved the problem of low temperature and easy fracture, but toughness and elasticity are still the main reasons why Cybertoruck cannot launch mass production. Stainless steel inherently lacks toughness, that is, once deformation occurs, it will immediately lose its support, and the result is instantaneous distortion or even fracture, which is very unfavorable to collision safety design, even if it is a special 304L alloy, it is difficult to have a major change in physical characteristics.
For example, in 2018, the Ford Sharp/Wing Tiger (Escape) achieved a collision score of P (bad) at the IIHS Highway Safety Insurance Association in the United States, because when the vehicle collided, the A pillar was deformed, and the reason for the deformation was precisely because it used ultra-high-strength stainless steel metal, and when a serious collision occurred, the A pillar twisted and caused serious deformation, thereby invading the interior of the cabin and squeezing the legs of the co-pilot passenger.
The elasticity problem of stainless steel is more serious, stainless steel is inherently hard and structurally stable, so that the vehicle can not produce a collision buffer in the event of a human collision, thus giving all the impact force to the victim, which is one of the reasons why Cyberruck has not participated in the IIHS Highway Safety Insurance Association crash test in the United States.
Similarly, Cybertruck's ability to have such a "fresh" appearance is also caused by stainless steel metal. Because of the poor ductility of stainless steel, it is not possible to create a varied arc surface like a steel plate, not to mention designs such as a layered waist line. If this is the case, the stainless steel plate is easy to pre-crack before the collision occurs, so Tesla's claimed "imitation stealth fighter" style is actually bowed to the stainless steel body.
The dream of a rich boy
Just as the so-called "first full stomach, then medical treatment", Tesla Model 3 sales in the domestic market have made many traditional car manufacturers admire the five-body investment, but also let Elon Musk have enough money and energy to think about his next step. The result of the opening of the altar through a "banknote ability" is the amazing Space X and Cyberruck.
It is undeniable that Elon Musk has a deep business acumen, which has become a "private KOL" for tesla, SpaceX and other brands. Then again, it seems that every Tesla model comes with countless topics, and whether Cyberruck will be able to debut in 2023 as Elon Musk wishes is still unknown, most importantly through the IIHS crash test.
Of course, in the era of rapid technological development, we should not burn the piano and cook the crane. Whether a rich boy's dream can be realized or not is not judged by the author through an article. At least, he dared to try to realize his dreams. The birth of the film "Back to the Future" has influenced generations, in the era of no flying cars, hoverboards, drones, people through endless creativity to envision the future, and now that we have everything imagined by our predecessors, should we look forward to the future?
