American car specialist Clive Sutton has created a new track-focused version of the UK’s most-powerful Ford Mustang.
Called the CS850R, the modified Mustang packs a colossal 847hp and has received a comprehensive makeover both inside and out.
It follows on from the Sutton CS850GT, launched last year to meet demand for a right-hand-drive answer to the Shelby GT500.
Doubling up on ponies
The CS850R uses a 5.0-litre V8 engine with a custom-tuned Whipple supercharger. Along with an XForce exhaust system and a new intercooler, this almost doubles the standard Mustang’s 454hp power output.
A six-speed manual transmission handles the 665lb ft of torque, helped by a Torsen differential specific to the CS850R. The final-drive ratio has been lowered to make acceleration feel even more aggressive.
The standard MagneRide suspension has been replaced with new Pro Active dampers. Upgraded springs and anti-roll bars, along with detailed tweaks to the Mustang’s alignment, improve its cornering ability.
Performance DBA brakes are hidden behind 20-inch Vossen wheels.
Sutton took inspiration from the Shelby GT500 for the CS850R’s styling. This includes a carbon fibre bonnet, deeper front splitter and upgraded LED headlights. The latter can be adjusted via a Bluetooth app to change their colour.
More carbon fibre is used for the side sills, boot lid, rear bumper and diffuser. Customers can specify a larger fixed rear spoiler, which is also made from carbon fibre.
The interior is dominated by a set of Recaro bucket seats, finished in a combination of leather and Alcantara. Red stitching is used throughout the cabin, including for the black Alcantara headlining.
Carbon fibre trim covers the dashboard, with a red billet starter button fitted for good measure.
Big power, big price
We previously tested the (slightly) less powerful CS800 Mustang from Clive Sutton. Our Tim Pitt said: ‘With stiff suspension and slightly vague steering, the CS800 is no paragon of poise, but nor is it simply an unreconstructed drag racer’.
With the wealth of chassis upgrades thrown at the CS850R, expect it to be a much sharper track tool.
Prices start at £121,000, with multiple options for additional customisation on top. Buyers can also make use of Sutton’s new online configurator to design the Mustang of their dreams – then submit it for a build-quote.
