Shelby resurrects the KR moniker for a monstrous Mustang

Welcome Internet, to the Ford Shelby GT500KR Mustang. Now, Mustang nerds among us will know that KR stands for ‘King of the Road’, with the badge being used on massively modified GT500s in both 1968 and 2008.

The previous GT500KR – based on the fifth-gen Mustang – had 540bhp, 40bhp more than the GT500 of its time. This newly unveiled KR has over 140bhp more than the modern-day GT500 it’s based on, meaning a total of over 900bhp from the supercharged 5.2-litre V8 (although Shelby hasn’t actually confirmed a final figure). Good grief.

Performance upgrades include a new Whipple supercharger, a new intake system and intercooler, adjustable front and rear springs and a Borla exhaust with what Shelby describes as a “bolder” sound. The standard GT500 is easily one of the loudest cars on sale today, so presumably the KR can resurrect the dead with its noise. 

Other Shelby enhancements include a new and extremely well-ventilated carbon fibre bonnet, shiny 20-inch forged wheels, a carbon front splitter and rear diffuser and a mega new carbon gurney flap on the wing. You can even get a full widebody version. That’d make a statement.

Just 225 examples will be built worldwide, with the first being auctioned off for charity by Barrett-Jackson. Thoughts?
