New Elon Musk book tells tale of how Tesla Cybertruck started as round and aluminum
The Tesla Cybertruck was a lot of things before it became what it is now, and before CEO Elon Musk and Chief Designer Franz von Holzhausen landed on a cyberpunk, stainless steel truck with sharp lines and edges, it was initially designed with curves and an aluminum exterior.
According to an excerpt from Walter Isaacson’s new book titled, “Elon Musk,” the Cybertruck was originally designed as something that was relatively “normal” in the grand scheme of things. Von Holzhausen and Musk would collaborate in a design studio behind SpaceX Headquarters in Hawthorne, Los Angeles, every Friday.
It was a serene time of the week as Tesla had fended off near bankruptcy, three vehicle launches, and, around this time, what Musk called “production hell,” referring to the Model 3 launch.
In early 2017, Musk and Von Holzhausen had started kicking around ideas for the Cybertruck, and in over two years, they’d unveil their design to the world.
In the past, we’ve seen images of how massively wide the scope was for the Cybertruck. It was not always the design that we have come to know as the Cybertruck:
An excerpt from the book confirms that:
“Beginning in early 2017, they began kicking around ideas for a Tesla pickup truck. Von Holzhausen started with traditional designs, using a Chevrolet Silverado as a model. One was placed in the middle of the studio, and they studied its proportions and components. Musk said he wanted something more exciting, perhaps even surprising. So they looked at historical vehicles with a cool vibe, most notably the El Camino, a retro-futuristic coupé made by Chevrolet in the 1960s. Von Holzhausen designed a pickup truck with a similar vibe, but as they walked around the model they agreed that it felt too soft. “It was too curved,” von Holzhausen says. “It didn’t have the authority of a pickup truck.”
Eventually, Musk and Franz made a trip to the Petersen Automotive Museum, where they realized something that would end up being a key point of their presentation in November 2019: pickup trucks are essentially all the same.
“We realized that pickup trucks basically haven’t changed in their form or their manufacturing process in eighty years,” Von Holzhausen said.
They then started kicking around ideas on how they could make this pickup unique. The first thing was what material it could be made of, and initially, aluminum was what was ideal. But titanium was also in the conversation due to its durability.
Musk came in and announced one day after weeks of deliberation on potential materials, “We are going to do this whole thing in stainless steel.”
Not everyone in the Tesla Design Studio was on board, either. Engineers and others heard rumblings of severe pushback against the project, and they were hoping Musk would withdraw his idea for the Cybertruck and go with something more traditional.
He told those in the Design Studio, “We’re not doing a traditional boring truck. We can always do that later. I want to build something that’s cool. Like, don’t resist me.”
In November 2019, Musk and Franz unveiled the Cybertruck.

And now, nearly four years later, the Cybertruck is nearing its first deliveries, and Tesla plans to hand over the first units by the end of the year.

A Tesla Semi caught fire in Hayward, California, which caused both directions of traffic to shut down for hours before being completely reopened early on Wednesday, the California Highway Patrol said.
The fire occurred just after 5:30 local time in Hayward on Tuesday, as the Semi caught fire in the southbound lanes of I-880 before CHP officials made the decision to shut down both lanes of traffic due to potential risks from hazardous chemical smoke.
There were no injuries reported.

The cause of the fire is currently unknown, as neither Tesla nor the CHP have not determined a cause.
However, some images taken before the Semi was completely destroyed by the fire seem to indicate this might have been an older unit, as it appears to be one of the designs that Tesla shipped as part of its pilot program, before revising it and starting mass production just a month ago.
@Tslachan From on of the videos looks like it’s an old Semi (not the refresh version that recently started production) https://t.co/KzwmR2kXow

At the time of publication, CHP had not returned our request for a comment for additional details, including the Semi involved and any potential collaboration on an investigation between the CHP and Tesla. We will update this story when we hear back from them.
The southbound lanes were reopened at 3:30 a.m. on Wednesday, with the northbound lanes opening last night a few hours after the fire began. The CHP did state that the lithium batteries were “incredibly difficult to extinguish,” according to NBC Bay Area.
The truck’s driver said that the Semi caught fire, but he did not have an explanation.

Tesla’s launch of the “Emergency Drive Away” function a few months back offered owners a safe option to evacuate an area if they were in reasonable danger. The function finally got its first use in the real world, but it appears it was by mistake.
A video shared by u/Joshalander in the r/TeslaLounge subreddit recorded the instance from his vehicle and said the incident took place in Austin this past weekend during the city’s F1 Race.
“Was charging around 6 AM this past Sunday in Austin before heading to the F1 race and heard a pop. Looked over and saw the new emergency drive-away feature in action. Genuinely felt bad for the dude when he got out and realized what happened, since he looked exhausted and only seemed to half-read the prompts.”
🚨 Here’s the first look at Tesla’s Emergency Drive Away function in action:
Apparently this driver accidentally enabled it and drove forward; you can see the Supercharger pull with the car.
Tesla said previously this would cost up to $25k if not used properly. https://t.co/B4qQRrsO6B

Emergency Drive Away unlatches the Supercharger connector from the vehicle, but still causes damage to both the car and the Supercharger. Tesla has said that it will cost up to $25,000 in repairs to have everything fixed back to normal.
Additionally, the company said that if it were not used in an emergency situation, the driver of the vehicle who activated the Emergency Drive Away feature would be responsible for all repair costs.
Tesla constitutes the following situations as reasonable justifications for activating the feature:
- You face an immediate threat to your life or personal safety.
- You must leave the area immediately.
- Exiting the vehicle is unsafe.
- Unplugging the charge connector would unreasonably delay your departure or expose you to a risk to your personal safety.
After using the feature, Tesla requires the driver to schedule Service so the car can be inspected.

Tesla’s Cybercab battery design could make robotaxis even cheaper
Tesla built the Cybercab’s battery pack with spare room for a future switch to LFP.
Tesla built the Cybercab’s battery pack with empty space inside it on purpose, and the reason points to a cheaper robotaxi down the road.
Robert Sumpf, Tesla’s director of mechanical design engineering for battery modules and packs, said the extra room beside and beneath the Cybercab’s modules was left there so the company can move to lithium iron phosphate cells later. “So, we protected this pack to go to an even lower energy dense chemistry as we scale and need to bring LFP into the platform,” Sumpf said in a Cybercab deep dive with Munro Live.
The Cybercab runs on Tesla’s own 4680 cells with a nickel chemistry today. LFP cells store less energy for their size, so a straight swap would cut range. The reserved space lets Tesla add more LFP cells to make up the difference. In return, Tesla would get cells that cost less, run cooler and survive more charge cycles. LFP became the most used EV battery chemistry in the world last year.
Not all of that room was planned for a chemistry change. Lars Moravy, Tesla’s Vice President of Vehicle Engineering, said part of it exists because “we didn’t need as many batteries as we thought we did.” Tesla told Sandy Munro in early 2025 that it was targeting a Cybercab pack under 50 kWh with close to 300 miles of range.
The pack also breaks from the structural design Tesla used in some Model Y and Cybertruck builds. Instead of potting hundreds of cells into one block, the Cybercab uses four separate, individually sealed modules, so a bad module can be replaced without scrapping the whole pack. Sumpf was blunt about the older approach, giving the Model Y structural battery “a grade D” because it was hard to build and nearly impossible to repair. He estimated a fully structural pack gains about 10% more cell volume, but said “the issue is the service cost.”
That cost matters more for a car that rarely sits parked. Cybercab chief engineer Eric Earley said replacing an entire pack “before half a million miles is a killer on cost,” which is why remanufacturing and serviceability were built into the design from the start.
The same Munro Live tour produced Moravy’s admission that the Cybercab line at Giga Texas is now outpacing Robotaxi deployments, along with a look at the robotaxi’s unorthodox paint process. Tesla is aiming to deliver the first Cybercabs to outside customers by the end of 2026, though Elon Musk has said the vast majority will stay owned by Tesla and run as a transport service.
Sumpf did not give a date for an LFP version, name a cell supplier or say how a chemistry change would affect range. For now, the 4680 cars keep piling up: Texas DMV records from Tuesday list 544 Cybercabs authorized for Tesla’s Robotaxi fleet, more than the 507 Model Ys on the same roster for the first time.
