Tesla’s chief designer accidentally broke the “armored glass” window of a $61,000 Cybertruck with a metal ball. Now he says it was a “great marketing moment”

  • During the 2019 unveiling of the Tesla Cybertruck, the company’s chief designer, Franz von Holzhausen, threw steel balls at the truck to prove its sturdiness, but it broke two windows. In an interview, von Holzhausen said the crash became “a big marketing moment.” Tesla began selling T-shirts alluding to the crash, and CEO Elon Musk claimed the company received 200,000 orders for Cybertrucks in the days following its launch.

Some might call Franz von Holzhausen’s accidental destruction of a Tesla Cybertruck window a blunder; von Holzhausen would prefer to call it a “great meme.”

During the 2019 unveiling of the Tesla Cybertruck, von Holzhausen, the company’s chief designer, threw steel balls into the vehicle, intending to prove that the windows CEO Elon Musk said were made of “armored glass” were indeed very tough. The windows, however, unexpectedly shattered, leaving Musk to deliver the rest of his presentation about the new truck while standing in front of the damaged car. Tesla shares fell more than 5% the next day.

While the incident seemed like an omen, indicating that the Cybertruck was about to fail, the botched demo actually opened up an opportunity to give the new model the spotlight, von Holzhausen said in an interview with Tesla Club Austria published earlier this year.

“It was just one of those Murphy’s Law things where something bad happens, but it turned out to be a great meme,” von Holzhausen said, referring to the phenomenon of when something can go wrong, it usually does. “And I think in a weird way — we’re not marketing — but it turned into a great marketing moment.”

He added: “It wasn’t an expected moment, but at that moment, you have to come back with it.”

Following the vehicle’s unveiling, Musk posted a video on X of von Holzhausen throwing a steel ball at the Cybertruck model before launch, its windows withstanding the force of the throw with no visible damage. The video has been viewed more than 6 million times within three days of its posting.

“I guess we have some improvements to make before production haha,” Musk wrote.

Days later, Musk praised the success of the Cybertruck launch, saying Tesla had received more than 200,000 orders for the vehicle. While Tesla doesn’t disclose Cybertruck numbers when it reports earnings, bundling them with the Model S and X, the company recalled nearly all Cybertrucks it had on the road earlier this year due to a problem where an exterior panel could detach, and that numbered only about 46,000 vehicles.

Despite Musk’s pre-order optimism, the Cybertruck’s lackluster launch was a sign of things to come for the vehicle. Although Musk initially boasted that the truck would retail for just $39,900 when it was expected to hit the market in late 2021, the Cybertruck has faced years of delays, debuting in November 2023 with a price tag of $60,990.

Tesla tried to make up for the broken glass accident with a $45 T-shirt sold on its website, but the brand was developing an otherwise sour reputation elsewhere on the Internet. In particular, concerns have grown over the safety of Cybertrucks, which have seen numerous recalls due to a malfunction in the tire pressure monitoring system, among other problems — including the aforementioned recall of all 46,100 Cybertrucks ever delivered in March.

To compound matters, there have been several deaths from Cybertruck crashes. A wrongful-death lawsuit claimed the truck had faulty safety mechanisms after a Houston man died in a crashed Cybertruck that burst into flames.

Safety concerns and recalls associated with the Cybertruck have coincided with weak sales for the truck. Demand for the vehicles held steady last year, but Cybertrucks piled up in lots over the summer as dealers navigate their inventory of unwanted vehicles.

Just 16,097 Cybertrucks were delivered in the first three quarters of this year, according to Cox Automotive data, a 38 percent year-over-year decline, dwarfed by the beleaguered Ford F-150 Lightning, which is being discontinued in its all-electric form due to falling demand.

Sales of the Tesla truck have been so dire that Musk-owned SpaceX has purchased 1,000 Cybertrucks from Tesla and may buy up to 2,000 vehicles. electric reported last week, citing an anonymous source. Earlier this year, another Musk-founded company, xAI, reportedly acquired unsold Cybertrucks.
