The iconic Mach 1 nameplate appeared for the first time on a UK-market, right-hand drive Mustang in the summer of 2021, and this new more performance-oriented Mustang was instantly recognisable by its redesigned front splitter and graphics. Advertised as 'the most track-capable Mustang ever to grace UK shores', its specification was very impressive and included MagneRide® adjustable dampers, a Tremec six-speed manual transmission with rev-matching technology for seamless down-shifts, a limited-slip differential, and an upgraded oil-cooler to keep the 454bhp 5-litre V8 cool whilst exploiting its prodigious performance. In true Ford tradition, at only £55,185, it was also fantastic value for money as the few cars available offering comparable performance were considerably more expensive.

The example modelled was added to Ford's Press Fleet on September 2nd, 2021, and retained until February 17th, 2023. During that time, it was used for Ford's corporate events or track driving days, and it appeared on TV twice, in the Wheeler Dealers' Yellow Car Special and BBC Top Gear's Christmas Special. It was also loaned to various magazines and newspapers for road-testing, including The Sunday Times, The Sun, The Mirror, Top Gear Magazine, Goodwood Media, What Car and Autocar. For the final ten months of its PR duties, it was on long-term test with CAR magazine, mainly in the care of the magazine's then deputy features editor, James Taylor, who was a big fan of the Mach 1's handling and character.
