Elon Musk has a baseball thrown at Cybertruck windows to prove they’re ‘rock proof’

Another day brings another Elon Musk stunt - and this time, it's to do with the long-awaited delivery of the Tesla Cybertruck.

The delivery of the pickups was two years behind schedule, but that didn't seem to bother billionaire Musk too much as he hosted an event at the Tesla factory outside of Austin, Texas.

“It's the most unique thing on the road. Finally the future will look like the future," Musk said after driving one of the trucks onto the stage.

Then, he got an executive to do a potentially embarrassing stunt: to throw a baseball at the Cybertruck's window.

This is to prove the truck's 'shatter-resistant Armor Glass' - which Tesla says can resist the impact of a baseball thrown at 70 mph.

If the stunt sounds familiar, that's because it is. Back in 2019, when the Cybertruck was first unveiled, chief designer Franz von Holzhausen lobbed a metal ball at one of the windows - which then cracked. As you can imagine, that was very much not the plan.

But van Holzhausen had another chance on Thursday - instead swapping out the metal ball for a baseball (which seems wise).

And luckily for Tesla, things went a lot more smoothly this time round, and the window didn't break. Although we've got to say, van Holzhausen did look a bit spooked and it was a pretty half-hearted throw of the baseball - so we're not entirely sure it would have broken a normal car window, even if it wasn't made of 'shatter-resistant Armor Glass'.

"I think we could probably have a pro pitcher lob it at it, it would still work," Musk said - but we'd like him to put his money where his mouth is, and see that in action.

Musk added: "The glass is tough, basically, is what we are saying" - and that's not the only feature of the futuristic-looking Cybertruck.

According to Tesla, the Cybertruck is "faster than a sports car" - it can go from zero to 60 miles per hour in 2.6 seconds - and has an "ultra-hard stainless steel exoskeleton" - and is, of course, fully electric.

During the event, a video was played showing someone shooting from different guns at the side of the truck - with the bullets only making small dents.

Much like the Tesla cars, the Cybertruck won't be cheap - Tesla said a rear-wheel-drive version would start at an estimated $60,990 (£48,200), and the high-end 'Cyberbeast' might set you back around $99,990 (£79,000).

And uncertainty still remains over the future of large-scale Cybertruck production - these are just the first dozen or so to be delivered, with the project plagued by manufacturing difficulties.
