This 1969 Ford Mustang is thought to be the only example in existence fitted with an AMG engine and it is just as insane as you’d imagine.

This Mustang has come to life thanks to a company by the name of Anarchy Garage in the UK and was once left to rot in a field for over 20 years. Fortunately, the tuning shop decided they would save the car and set about making it unlike any other.

Found at the heart of the Mustang is the 5.5-liter twin-turbocharged V8 from a 2021 Mercedes-Benz E63 AMG that has had its ECU tuned and now pumps out 721 hp. This power is sent exclusively to the rear wheels thanks to the E63’s original 7-speed automatic transmission and makes for a Mustang that could give some supercars a run for their money.

Featured in this video from Officially Gassed, the car picks up speed incredibly well. It has side-exiting exhaust pipes, sounds absolutely insane and according to the YouTuber, is one of the most violent cars he has ever experienced. The car was tested on wet roads but despite that, it puts all of its power to the ground surprisingly well.

Not only has the Mustang’s new powertrain been lifted from a E63 AMG but much of the interior also comes from the Merc, including the dashboard, steering wheel, center console, and transmission tunnel. What’s perhaps the most incredible thing about this build is that Anarchy Garage says it only spent £24,000 (~$33,000) bringing it to life and that includes the cost of both the Mustang and the E63 parts.
