Mat Armstrong takes on his toughest challenge yet

Mat Armstrong is back at it once again, ladies and gentlemen.

The popular automotive YouTuber has just set himself a new challenge.

And it might just be his most difficult yet.

This time, it doesn’t concern a Bugatti Chiron or another hypercar.

Instead, it involves a truly legendary supercar.

And the stunner is the Ferrari 812 Superfast.

Mat kicks off the latest video by explaining that he bought the car from a salvage auction.

He set himself the challenge of completely rebuilding the car in just 24 hours.

The problem is that the car had sustained an unbelievable amount of front-end damage.

As a result, several high-value components were also badly damaged.

The front bumper and ‘active aero’ flaps were missing or shattered.

In addtion, the radiators and cooling systems were also in need of repair.

Because of the front damage, this Ferrari 812 Superfast also suffered from deployed airbags.

This often triggers a ‘pyro-fuse’ that prevents Ferraris from starting to avoid electrical fires.

So, no small challenge for Mat, then.

Team works to get V12 beating heart restarted

Mat and his team – including his father and his mechanic, Liam 0 set a grueling 24-hour deadline to get the car back into a drivable, presentable state.

Phase one of the rebuild involved spending several hours stripping away the mangled carbon fiber and aluminum.

As you can probably imagine, Ferrari parts are notoriously expensive and have long waiting times.

So Mat had to get to work ahead of time to source second-hand parts and ‘specialist’ items.

These included new airbag modules and a new dashboard.

The second – and biggest – hurdle was getting the enormous 6.5-liter V12 to restart.

Even after replacing the damaged radiators and refilling the fluids, the car’s electronics remained locked.

But Mat Armstrong and the team managed to find a fix.

This involved bypassing several safety systems to reset the ECU.

After that, the incredible V12 roared back into life.

Can this all really be achieved in just 24 hours?

As they got into the final hours, Mat and his team struggled with the reassembly of the 812 Superfast.

This was mostly because of the complex fitment of the different body panels of the Ferrari.

In spite of the exhaustion and the late discovery of ‘hidden’ broken brackets, the goal was achieved.

The team managed to get the Ferrari 812 Superfast up and running once again.

Mat’s video highlights the level of engineering complexity of modern Ferraris and the massive financial risk involved in salvaging supercars.

One small part going wrong and a ‘bargain’ supercar can easily – and quickly – turn into a total loss.
