#Tesla Cybertruck stiffness

[odinsblog]

DURING THE CYBERTRUCK'S unveiling in 2019, Tesla CEO Elon Musk claimed that the electric vehicle's “ultra-hard stainless steel” body might be “literally bulletproof.” However, the Tesla truck's exterior panels appear to be defenseless against water pistols. They apparently rust, as some owners claim.

Posting on the Cybertruck Owners Club forum, a user named Raxar risked the wrath of the Tesla faithful—already exercised by the Cybertruck's numerous alleged design flaws—by stating that when they collected the $61,000 truck, “the advisor specifically mentioned the Cybertrucks develop orange rust marks in the rain.”

In a separate thread, the user vertigo3pc reported that “corrosion was forming on the metal” of his Cybertruck after it spent 11 days in the rain in Los Angeles.

Raxar, who also lives in California, posted what appeared to be close-up, rust-flecked images of his truck after driving it for two days in rain.

The Cybertruck does not ship with clear coat, that outermost layer of transparent paint that comes as standard on almost every new motor vehicle on the planet. Instead, each Cybertruck owner has the option to purchase a $5,000 urethane-based film to “wrap your Cybertruck in our premium satin clear paint films. Only available through Tesla.”

Who knew untreated stainless steel might not be such a good idea for the exterior of a motor vehicle, especially considering that cars typically get left sitting outside in all weather for 95 percent of their lives? The whole automotive industry, that's who.

Aside from the 1980s DMC DeLorean and a shiny 1960s Porsche, car companies have long steered clear of stainless steel panels. The material is heavy, relatively expensive, and hard to work with. It's also stiff, which makes it potentially more lethal to anybody unlucky enough to be struck by a vehicle built with the stuff.

Unsafe Design? Experts Raise Concerns about Tesla Cybertruck - Technology Org

The safety of Tesla’s Cybertruck is raising concerns among experts due to its angular design that features sharp edges and stiff stainless-steel exoskeleton structure which is most likely not compatible with the latest trends in automotive safety.

Six safety professors and officials, who analyzed crash test videos presented during a webcast delivery event, expressed worries about potential harm to pedestrians, cyclists, and other vehicles on the road, Reuters wrote in a recently published article.

Despite discussions on social media regarding the live-streamed crash test videos on November 30, experts emphasized the need for comprehensive crash-test data to draw definitive conclusions about the vehicle’s safety.

Previously, regulatory authorities were unimpressed by Elon Musk’s statements about the car’s ‘waterproof’ rating.

“The big problem there is if they really make the skin of the vehicle very stiff by using thick stainless steel, then when people hit their heads on it, it’s going to cause more damage to them,” explained Adrian Lund, the former president of the Insurance Institute for Highway Safety (IIHS), the organization responsible for an industry-standard for vehicle crash tests.

Previously, Tesla highlighted the Cybertruck’s structural elements designed to absorb impact during crashes. Tesla CEO Elon Musk said he was confident in the Cybertruck’s safety, claiming it would be safer for both occupants and pedestrians than other vehicles of the same class.

The vehicle’s unique design features flat planes and long, linear edges, making it visually distinct. It is the first car with a stainless-steel exterior since the introduction of the DeLorean car in 1985’s “Back to the Future.” Musk mentioned that the material’s toughness even caused the stamping machine to break while forming the panels.

What Is the Difference Between an SUV and a Crossover?

Alex Trebek looks at you and then carefully reads the card:

“While one of them rests on a ladder frame, the other has unibody construction” and then he looks up.

If you were a Jeopardy contestant and shouted “What is the difference between an SUV and a Crossover?” Alex would announce, “Correct!” You’d win the $300, and then shoot a knowing wink at the home audience. Saying that SUVs ride on ladder frames and crossovers have unibodies is the simplest, correct-est answer.

Yet there’s another, squishier answer, sort of the vehicular version of Supreme Court Justice Potter Stewart’s “I know it when I see it” for how he identified obscenity in 1964. And I’ll get to that at the end.

First off, what’s a ladder frame?

The ladder-frame chassis of the 2020 Chevrolet Suburban.

It’s pretty close to what it sounds like—two parallel rails with interconnecting stiffeners, laid horizontally. Stood up on end, it resembles a ladder. Spanning nearly the length of a vehicle, it’s a car’s steel skeleton, holding together all its major organs—engine, transmission, suspension, wheels, and bodywork skin—in place. Ladder frames are rampant among trucks, underpinning almost all of them (except for a few oddballs like the Honda Ridgeline and Tesla’s Cybertruck). And, judging by our Jeopardy success, underpinning SUVs as well.

The automotive ladder frame is ancient genetic material. Horse-drawn carriages were built upon them, and early car-builders (notably, Studebaker) just carried on with the practice as they transitioned from animal horse-power wagons to combustion horsepower cars. This wasn’t just a stubborn, archaic tradition, though. The rutted roads of the early-Twentieth Century required huge, heavy wheels, and together with a primitive understanding of springing and damping, it was a good thing that the ladder frame flexed a bit too. It was literally part of the suspension, the whole car becoming a giant spring, with weights and mini-dampers often attached to either end to tamp-down any nasty resonances. The emphasis was on strength, not stiffness, plus, a live axle-on-leaf-spring suspension easily mated with frame-rails.

As roads became paved and smoother, wheels and suspensions could be smaller and lighter, so having a flexible frame mattered less – and finally, an outright hindrance as brands (notably, Cadillac) better understood suspension theory. For instance, ride quality is helped by minimizing “unsprung weight” (considered the wheels, tires, and axles, plus half the pivoting parts). A heavy ladder frame is the last thing you want as part of the suspension mix.

OK, so what’s a unibody?

A Volvo XC40 showing off its unibody structure.

Like a ladder frame, a unibody is also what it sounds like. Instead of underfloor frame rails doing the work while the bodywork’s simply worn like a big hat on top, here, the whole, thin-gauge sheet metal structure—usually excluding most of the bodywork skin itself—carries loads. It’s distributed. As an aside, the French word monocoque, meaning “single shell,” is the unibody’s kissing cousin, except that much of its bodywork is substantially stressed as well, like a jetliner’s. It’s a rarity, usually seen in racing. (Though in that realm, its meaning is obviously malleable; many one-piece carbon-fiber racing chassis—with non-stressed bodywork, so just like a unibody—are commonly called monocoques, a term that’s simply more popular in Europe.)

What’s good about unibody construction?

There’s a list of things. The structure’s comparatively huge cross-section (10 or more times a frame rail’s height) makes it tremendously stiffer for its weight. Or inversely, lighter for the same stiffness, which greatly improves mileage. Crash safety benefits, too, as its folded-origami construction can be designed to collapse progressively, reducing your body’s deceleration upon impact. And handling improves because the suspension can be more complex as it can attach to a more three-dimensional structure, while its connection points don’t flex around as much as the chassis distorts, letting the tires accurately do their work.

With all these advantages, why would anybody still build a ladder-frame SUV? Good question. Which is why the vast majority of the offerings out there are unibody crossovers. But there are few justifiable instances. Serious off-roading returns us to those rough roads of yesteryear, once again demanding heavy wheels and suspensions, and a strong (if not stiff) structure to attach it to. Towing loads can make a beeline through the frame rails to suspensions where the wheels are doing the pulling.

By the way—there are many other types of chassis concoctions besides ladder frames and unibodies. The 1934 Chrysler Airflow anticipated unibody construction with a hybrid blend of a tubular skeletal frame webbed by load-bearing panels. Today’s C8 Corvette is hard to categorize, being a structure composed of cast, extruded, and sheet aluminum, all bonded together (the body is a non-load-bearing envelope).

What is it—an SUV or a crossover?

And what about Supreme Court Justice Stewart’s definition? I once attended a lunch with Subaru product planners who wanted our opinion on a new product they were considering “What if we raise the Legacy wagon (it had FWD) and give it all-wheel drive?” I thought they were crazy and said so. The SUV craze had just started and Subaru wanted in on it without actually building an SUV. So was born the Outback—what we now call a crossover. And why I’m not a product planner.

If a manufacturer thinks it’ll sell more unibody crossovers by giving them tough, SUV looks that we “know when we see it,” nobody can stop them. But it isn’t going to impress Alex Trebek.

A little stiff and noisy but it looks great and works as designed. The black swingarm runs against the body of the #CYBERTRUCKZILLA so it will need to be tweaked a little in the final design and if it is an issue we can simply cut it off. Amazing and complex design by @antsinafrica Andy is enjoying assembling this so much!! @tangiblecreative_official is reprinting the rear swingarm since the Chiron seems to be out of commission. #makersgonnamake ◇◇ ◇◇ ◇◇ #CYBERTRUCK #teslamotors #tesla #teslagram #TeslaCYBERTRUCK #cybertrucktesla #teslatruck #elon #elonmusk #musk #STEM #steam #plaidCYBERTRUCK #3dprint #3d #3dprinted #3drevolution #3dtoys #3dprintinglife #3dtoy #antsinafrica #additivemanufacturing #Tangiblecreative @andystechgarage #atg #andystechgarage ⚠️DO NOT REPOST❗⚠️ https://www.instagram.com/p/CBVSPCBDmOz/?igshid=1bpdmfvz1eeiu

Tesla’s cars and trucks aren’t ideal– here are all their most disappointing features

The Tesla Model 3. not quite best.

Matthew DeBord/BI.

Tesla’s lorries are usually outstanding.

However they aren’t ideal. The Design 3, Model S, Model X, the initial Roadster, Model Y, and Cybertruck all have frustrating defects.

Here’s a rundown of whatever I do not much like about the automobiles, from charging times to confined seats to weak design.

Visit Company Expert’s homepage for more stories

No car is.

In Tesla’s case, I went back over all the cars I’ve driven or assessed in some way and rounded up their flaws.

Here’s the rundown:

I’m a huge fan of Tesla’s vehicles. I’ve driven nearly all of them, and I in fact think the Design 3 might be the most idea-packed auto ever produced.

Tesla Design 3.

Matthew DeBord/BI.

The ultra-minimalist Model 3 interior sets a tone. If you like an uncluttered life, it’s for you. If you delight in some buttons and knobs due to the fact that they’re simpler to utilize than touchscreen technology, then you’re going to have a stuffed relationship with the Design 3.

Tesla Model 3.

The Design 3 has a wonderful glass roof, however to make it work, the fastback hatch is compromised. Thus, the Design 3 has a truck cover with a large cutout.

Which remains in exchange for a beautiful stock 15 cubic feet of freight capability.

Tesla Design 3.

Matthew DeBord/BI.

The front trunk, or frunk, makes up for it. But that does suggest you have two hatches to handle.

Tesla Design 3.

Matthew DeBord/BI.

The Majority Of the Model 3’s automobile functions are combined in a central, landscape touchscreen that beings in the middle of the lorry’s dashboard.

Tesla Model 3.

Matthew DeBord/BI.

In a week of testing, I grew tired of constantly having to communicate with screen. It didn’t damage my total impression of the Design 3, but to this day I long for more buttons whenever I evaluate a vehicle that’s following the Design 3’s lead.

Tesla Design 3.

Matthew DeBord/BI.

The Model 3 has an aftermarket wireless charging option that owners can acquire, but the stock 3 does not have the function, which has become fairly standard on high-end cars.

Tesla Model 3.

Matthew DeBord/BI.

The Model 3’s guiding wheel removed many multifunction buttons that are now typical. Instead, you get 2 thumb-wheels, which have to carry out a number of tasks apiece. Some folks enjoy the iPhone-ish simpleness of this plan. I’m not one of them.

Tesla Design 3.

Matthew DeBord/BI.

The Model S, in some methods, is Tesla’s masterpiece: it’s the very first clean-sheet style, introduced in2012 Not much to grumble about, however …

Tesla Model S.

Tesla.

… the Design S gave us both Ridiculous velocity mode and later Ludicrous Mode. These features are remarkable. Ludicrous Mode yields a 0-60 mph time that’s faster than some supercars. This is a SEDAN! Unless you want to tie whatever down, your Ridiculous runs may end up being more scarce.

Tesla Model S.

Mark Ralston/AFP.

The Model S is a slow, slow charger when you’re utilizing a fundamental wall outlet. It’s true “trickle” charging, about one mile per minute. In practice, unless you have a great deal of time to kill, it’s hardly worth it.

A Tesla Design S juices up behind a shed.

Matthew DeBord/Business Expert.

The Design X is Tesla’s most remarkable, modern lorry. It’s specified by its upswinging, falcon-wing rear doors.

Tesla Design X.

Tesla.

They are cool. After a few days of testing the Model X, I found myself wanting there was a more simple, old-school door alternative.

Tesla Model X.

Matthew DeBord/BI.

The Design X has a third-row choice. But since the SUV isn’t a proper full-size ute, there’s almost no space back there for normal-sized adult people.

Tesla Model X.

Matthew DeBord/BI.

Charging for Teslas is both a virtue and a curse. The business’s global Supercharger network is prevalent and enables fast-charged journey that surpass its cars’ currently significant range.

Tesla Design X.

Matthew DeBord/BI.

However the fastest charge can still consume an hour, depending upon how depleted the battery is. And while Teslas can compute how long to charge, based on how a trip has actually been outlined, it’s constantly longer than a five-minute fill-up in a gas-powered cars and truck.

Matthew DeBord/BI.

Like the Design 3, much of the Model X’s functions are handled through a substantial touchscreen, with a portrait design much like the Model S. And like the Model 3, one establishes a love-hate relationship with the setup.

Tesla Model X.

Matthew DeBord/BI.

The initial Roadster was Tesla’s first automobile, and it was groundbreaking: sexy and quickly, miles beyond the glorified golf carts that electrical cars had actually been.

The original Tesla Roadster.

Matthew DeBord/Business Insider.

However it likewise had maybe the worst infotainment system in all of cardom, even by the standards of the early 2000 s.

The initial Tesla Roadster.

Matthew DeBord/Business Insider.

The Roadster was also a relatively pure cars: heavy steering, a stiff flight, and absolutely no versatility.

The original Tesla Roadster.

Matthew DeBord/Business Insider.

The Model Y is Tesla’s newest lorry– and the crossover SUV is the company’s first unsightly effort.

Tesla Design Y.

Tesla.

Compact crossovers tend to be unimpressive aesthetically, anyway. However compared with Tesla’s current lineup, the Design Y is the ugly duckling.

Tesla Design Y.

Matt Debord/Business Expert.

I’m of two minds about Tesla’s semi-self-driving system, Autopilot. On the one hand, it has incredible capacity, although I don’t believe it’s now a lot more than innovative cruise control.

Benjamin Zhang/Business Expert.

The problem is that it’s rather tiring to use.

Benjamin Zhang/Business Insider.

The system is also lagging some of the much better highway-only hands-free offerings, particularly Cadillac’s Super Cruise tech.

Tesla.

The extreme brand-new Cybertruck has a questionable style, but I invited it. With the Design Y, the company has fallen into a rut.

Tesla Cybertruck.

FREDERIC J. BROWN/AFP through Getty Images.

Still, the Cybertruck echoes the Model X in having actually made complex, retractable bedspread for its “vault.”

Tesla Cybertruck.

Tesla.

Bed covers– or “tonneau” covers– are a familiar pickup-truck option.

Jeep Gladiator.

Matthew DeBord/Insider.

The Cybertruck likewise has a stainless-steel construction. That may sound outstanding. But there’s a factor we don’t have any stainless-steel cars and trucks– and haven’t since the unfortunate DMC DeLorean. Hmmm … also gull-wing doors.

Timothy Morris/Getty Images.

Finally, while Tesla’s battery style allowed it to conquer the EV world early, it’s something of a long-lasting drawback. It consists of thousands of lithium-ion cells, all wired together in packs. The layout is inefficient– and highly lithium-dependent.

Tesla reveals Cybertruck, but breaks its ‘unbreakable’ windows during unveiling

https://newsource-embed-prd.ns.cnn.com/videos/newsource-video-embed.js

HAWTHORNE, Calif. — The Cybertruck has arrived and it looks nothing like any pickup truck you’ve ever seen.

Tesla CEO Elon Musk revealed the long-awaited electric pickup truck at its Design Studio in California, just outside Los Angeles.

When the truck initially drove onto the stage, many in the crowd clearly couldn’t believe that this was actually the vehicle they’d come to see. The Cybertruck looks like a large metal trapezoid on wheels, more like an art piece than a truck.

Instead of a distinctly separate cab and bed, the body appears to be a single form. The exterior is made from a newly developed stainless steel alloy, the same metal that’s used for SpaceX rockets, Musk said. That alloy enables the car to be “literally bulletproof” against at least smaller firearms, including 9-millimeter handguns, Musk said.

A man with a sledgehammer hit the sides of the truck without damaging it. But a demonstration of the truck’s supposedly unbreakable metal glass windows backfired when a metal ball thrown at the windows did, in fact, break them.

“But it didn’t go through,” Musk sheepishly pointed out.

Incredible power at an incredible price

Musk has made striking claims about the truck’s capabilities. Among them, he has said the Cybertruck would be more capable, in terms of towing and hauling, than a Ford F-150, and it would perform as a better sports car than a Porsche 911.

The most expensive version of the truck, the Tri Motor All-Wheel-Drive, will be able to carry 3,500 pounds, tow up to 14,000 pounds and go from zero to 60 in 2.9 seconds. It will also be able to drive up to 500 miles on a full charge. Base models will have a range of 250 miles.

In addition to being able to carry cargo in its bed, the truck will have lockable storage spaces under the hood and in the sides. The bed itself also has a sliding cover. Drivers will also be able to adjust the ride height of the truck, for when they are on the highway or off-road, using an adaptive air suspension system.

Another eye-catching feature of the truck is its price. The base version of the truck will start at $39,900. That’s only about $10,000 more than the price of a base model Ford F-150, which starts at about $30,000. But it would compete well with the cost of a nicely equipped F-150. An F-150 Lariat Super Cab, for instance, starts at about $44,000.

Prices for the top end Tri Motor AWD version of the Cybertruck start at $69,900. Buyers will also be able to choose Tesla’s “self-driving” option for $7,000. (The truck should be able to drive itself once the software for that becomes available.)

Musk had one final surprise as the presentation was wrapping up.

“Oh, yeah,” he said. “We also made an ATV.”

With that, a rider came out from a side room on a small electric all-terrain vehicle. He flipped down the truck’s tailgate, extended a built in ramp, and rode it up into the bed.

‘A niche product at best’

Tesla’s new electric truck won’t be without some stiff competition. It’s going up against the two market leaders in full-size trucks in America. Ford is developing its own electric F-series truck, while General Motors, which makes Chevrolet and GMC pickups, also has its own electric pickups in the works. Earlier Thursday, GM CEO Mary Barra said the auto maker expects to begin selling its electric pickup in the fall of 2021.

Rivian, a Michigan-based start up also plans to begin selling its own electric pickup next year. The company counts Amazon and Ford as major investors. Rivian founder, R.J. Scaringe, ranked third on this year’s just-released Motor Trend Power List, a largely subjective ranking of relative auto industry mojo. Musk ranked 24th. Rivian’s trucks will cost tens of thousands of dollars more then Tesla’s, but they will look far more like trucks.

The market potential for Tesla’s truck remains somewhat of a mystery. There has, to date, been little overlap between full-size pickup truck buyers and Tesla buyers. For instance, Teslas and other electric cars sell well on America’s coasts, while large pickups sell best in the Midwest.

Also, Tesla’s Cybertruck looks nothing like a traditional pickup. Truck buyers may want to stand out, but it’s unclear they’ll be comfortable with standing out quite so much.

“It will be a niche product at best and poses no threat in the pickup market as we know it today. The other downside is that this truck will have no federal tax credits by the time it comes out,” said Matt DeLorenzo, senior executive editor at Kelley Blue Book.

Musk has said in the past that the pickup is something of a personal pet project and he doesn’t care much if few people actually want to buy it.

Chelsea Sexton, an analyst who covers the electric vehicle market, said she doesn’t believe the truck Musk showed is very close to the final production vehicle.

“From a specification standpoint, I believe that’s probably what they’re aiming for but, no question, that body style that is not a high volume product,” she said.

Production will begin in late 2021, with production of the Tri Motor AWD version of the Cybertruck beginning a year later, according to Tesla.
