Watch Stig take an 847bhp modified Mustang around the Top Gear track

The Top Gear test track has played host to multiple fast, modified Mustangs in the past, and this one is now officially the fastest. It’s the CS850R, Clive Sutton’s upgraded version of its already upgraded Ford Mustang (the CS850GT) and it has been optimised, just like The Stig, for track driving.

CS takes the base Ford Mustang and its 5.0-litre V8, and adds a bespoke Whipple supercharger, intercooler and active exhaust. That increases power from the standard 454bhp to an alarming 847bhp and 665lb ft of torque. Get ready for some serious supercharger whine...

Back in 2007 the Shelby GT500 set a 1:30.0, and the Roush Mustang upgraded to a 1:28.0. The CS850R managed an impressive 1:22.3 at the hands of The Stig - and on a VERY hot day too.
