The automotive world has been glued to YouTube over the past few weeks as Mat Armstrong takes on one of the wildest rebuild projects the platform has ever seen – rebuilding Alex’s crashed Bugatti Chiron.

What started as another ambitious rebuild series has quickly turned into one of the biggest talking points in the supercar community, especially after comments and reactions linked to Rimac and the wider Bugatti network appeared online.

For fans, it’s everything car culture is about: passion, problem solving, and proving that damaged hypercars don’t always belong in a museum or scrapyard. But for manufacturers, it raises serious questions about safety, brand reputation, and whether these multi-million-pound machines should ever be rebuilt outside of official channels.

The rebuild nobody expected

The crashed Chiron, owned by Alex, looked beyond saving when it first appeared online. With heavy damage and eye-watering repair costs, many assumed the car’s future was over.

Mat Armstrong built his reputation doing exactly what most people think is impossible, from rebuilding crashed Lamborghinis and McLarens to bringing written-off performance cars back to life. Mat has become one of the biggest automotive creators on YouTube because of his willingness to take on projects others avoid.

This time though, it’s the first rebuild Mat is doing for someone else’ live’s car and the stakes are on another level. The Bugatti Chiron isn’t just any supercar. It’s one of the most advanced and exclusive hypercars ever produced, powered by an 8.0-litre quad-turbo W16 engine producing nearly 1,500 horsepower. Every component is engineered to extreme tolerances, making repairs incredibly difficult and unbelievably expensive.

Why Rimac reportedly isn’t happy

Following Bugatti’s merger into Bugatti Rimac, the Croatian manufacturer now plays a huge role in the future of the Bugatti brand. Reports and online discussions suggest the company is far from impressed with the rebuild series, refusing to provide necessary parts and support to allow this repair to happen. This forces Mat and the team to improvise heavily, searching for parts available from other manufacturers and soon finding the same parts for a fraction of the cost that Bugatti charges as a replacement.

Mat also uses everyday upholsterers , to create a bespoke interior, making this rebuild a one-of-one unique Bugatti, check this out.

While no official public statement directly targeting Armstrong has been released, reactions from people close to the industry and discussions online hint at major concerns, and honestly, it’s easy to understand why.

Manufacturers spend millions developing safety systems, structural integrity, and strict repair procedures. Seeing an independent creator dismantle and rebuild a hypercar in a home workshop environment naturally creates tension.

If something goes wrong after a rebuild, it could reflect badly on the brand, even if the manufacturer had nothing to do with the repairs.

There’s also the issue of exclusivity. Brands like Bugatti carefully protect their image, and seeing one of their halo cars stripped apart on YouTube for millions to watch is very different from the polished perfection usually associated with the marque.

The internet loves it

Despite the controversy, fans cannot get enough. The series has exploded across social media because it represents something raw and authentic in a world where many supercar channels focus purely on luxury lifestyles and showroom-perfect cars.

Watching a heavily damaged hypercar slowly come back to life is addictive content, especially when the project feels almost impossible.

For many viewers, Mat Armstrong represents modern car culture perfectly, proving that knowledge, determination, and creativity can compete with massive manufacturer budgets. Some fans have even compared the project to the early days of modifying Japanese performance cars, where enthusiasts challenged the idea that manufacturers should control every aspect of ownership.

Should owners be free to rebuild their own hypercars however they want?

Or are vehicles like the Bugatti Chiron simply too advanced and dangerous to repair outside official factory networks? Or, should the mystery remain the mystery?

Millions of people are watching to see whether Mat Armstrong can pull it off and in the latest video, Alex petrifies Mat by raging the car for the first time since the crash.
