The Cybertruck is something that’s completely out of this world—so much so that when people are unfamiliar with it, their first reaction is often, “What is that?”
And stepping inside only reinforces that impression. With its hidden-button doors and sleek, futuristic interior, the Cybertruck truly feels like something from another world. Recently, Tesla’s Chief Vehicle Designer, Franz von Holzhausen, revealed that an image shared by the official Cybertruck account on X is actually the original sketch that inspired its radical design.
Many Iterations
The Cybertruck has undergone numerous design iterations, and we’ve had the chance to explore some of Tesla’s earliest concepts for a truck that would define the future in many ways. These insights come from Walter Isaacson, who detailed them in his biography of Elon Musk.
Originally shared in 2023, the images revealed a dramatically different vision—one without the now-iconic angular rear sail. The design drew inspiration from various art forms, including video games, books, and movies—essentially, anywhere sci-fi had imagined a sleek, futuristic, or rugged truck.

The design that ultimately made it to production wasn’t one of those early concepts. Instead, it was inspired by none other than the infamous American F-117 Nighthawk—a now-retired, single-seat stealth bomber developed by the secretive Skunk Works for the U.S. military. As the world’s first stealth aircraft, the F-117 revolutionized aviation with its groundbreaking design.
Much like the Cybertruck’s deluge of new technologies, the F-117 brought innovations that reshaped modern aircraft design. Its angular, faceted surfaces were engineered to deflect radar waves and reduce its infrared signature—features that directly influenced the Cybertruck’s distinctive geometry. When wrapped in black, the resemblance to the Nighthawk is undeniable.
Now, while we can’t say for sure if the Cybertruck is truly “stealthy”—since it turns heads wherever it goes—it does reflect radar waves. That said, don’t expect it to help you evade speed cameras or slip past the police unnoticed.
Super Stealthy
Not a Tesla App
The Nighthawk’s angular design also required advanced computerization—because, at first, no one believed it could even fly. Without its onboard computers to fine-tune the pilot’s inputs, it simply wouldn’t have. Similarly, the Cybertruck’s steer-by-wire system and rear-wheel steering give it an unexpected level of agility—especially for a massive stainless-steel vehicle that’s this fast.
The Cybertruck is truly one of a kind—there’s nothing else like it on the road today. Franz von Holzhausen delivered on Elon Musk’s vision of a truck from the future, and Tesla’s engineering team brought that vision to life in a way that few thought possible.

Tesla is getting ready to start rolling out FSD support for hardware 3 vehicles in China. Tesla is internally testing what appears to be a build of FSD V12.6 on HW3 vehicles with its employees.
A post on Chinese social media platform Rednote initially shared the software update details and was then shared by Tesla Newswire. We’ve verified that the vehicle in question is a 2023 Model Y, confirming it falls within the HW3 hardware generation.
We reviewed FSD V12.6 in depth here, and provided a comparison to FSD V13 here, but here’s the key points you’ll need to know.
FSD V12.6 is Tesla’s latest revision of FSD for HW3 vehicles and it’s is very comparable to FSD V13 in terms of features. It includes 3 speed profiles, Chill, Standard, and Hurry, which control how aggressive FSD is in making lane changes and ensuring it stays at, near, or above the speed limit.
This version of FSD also comes with an improved controller, as well as earlier and more natural lane change decisions, making it far more capable than V12.5 or V12.3 builds.
For Chinese customers getting their first taste of FSD after using Autopilot for years, it’s mindblowing. It can handle city level streets, hanlde turns and traffic control signs and get you to your destination with minimal interventions.
When Does It Release?
Given’s China’s more crowded streets and more complex road layouts, we weren’t sure whether Tesla would introduce support for HW3 vehicles in the market. This news is a positive and encouraging sign, not only for FSD in China, but for all HW3 vehicle owners out there.
Tesla usually releases updates to employees in advance of releasing them to its general customers - providing them with a second chance to find and fix bugs. Usually, once updates make their way to employee vehicles, and barring any major issues, they begin rolling out to customers within one to two weeks.
China currently requires owners to buy FSD, as FSD subscriptions aren’t available in the country yet. If you’re in China and bought FSD on a HW3 vehicle, it may not be long before you have access to FSD.
Tesla’s Cybertruck has officially earned a 5-Star Safety Rating from the NHTSA—an impressive achievement given the vehicle’s design. The achievement demonstrates Tesla’s engineering prowess. As one engineer points out, it wasn’t an easy feat.
Interestingly, the NHTSA only recently disclosed the results, despite the crash tests being completed a while ago. According to Lars Moravy, Tesla’s VP of Vehicle Engineering, the team had been aware of the 5-star rating for quite some time. While the reason for the delay remains unclear, now that the results are public, Tesla’s engineers can finally share how they achieved the rating.
Crumple Zones
Wes Morril, the Cybertruck’s Lead Engineer, wrote about the crash test video on X recently, addressing the claims that the Cybertruck doesn’t have a crumple zone. He also posted a side-by-side video (below) of the engineering analysis and the crash test itself.
Engineered Crash Safety
There’s a lot of engineering precision at play when a Cybertruck is involved in a crash. Unlike traditional crash structures that rely on crash cans and collapse points, the Cybertruck’s front gigacasting is designed to absorb and redirect impact forces in a highly controlled manner.
It all starts with the bumper beam, which crushes within the first few milliseconds of a high-speed impact. At the same time, the vehicle’s sensors rapidly analyze the crash dynamics and determine the optimal deployment of safety restraints, including airbags and seat belt pre-tensioners. These split-second actions are crucial in keeping occupants safe.
As the crash progresses, the vehicle’s structure deforms in a carefully engineered sequence. The drive unit cradle bends, directing the solid drive unit downward and out of the way, allowing the gigacasting to begin absorbing impact forces.
The casting crushes cell by cell, methodically dissipating energy in a controlled manner. This gradual deceleration reduces the g-forces transferred to occupants, making the crash much less severe. As the gigacast begins crushing, the safety restraints are deployed.
As Wes points out in his post - you can see how accurate the virtual analysis and modeling were. The video shows the simulated crash side by side with the real-life crash test and they’re almost identical. All that virtual testing helps provide feedback into the loop to design a better and safer system - one that is uniquely different than any other vehicle on the road.
All the armchair experts claimed the Cybertruck has no crumple zone and I get it, the proportions seem impossible. It was a tough one and there is a lot of engineering that went into it. Let me break it down for you:
