High-performance and luxury car specialist Clive Sutton has launched the CS850R, a track-focused version of the UK’s most powerful Mustang. Based on the company’s 859PS (847bhp) CS850GT Mustang, the new model features a series of enhancements that fine-tune the car for spirited on-road and track driving.

The most significant upgrade is a new Torsen differential, which optimises mechanical drive from both rear wheels. This enhancement delivers more grip under aggressive acceleration, plus greater feel and finesse when pushing hard, or engaging a power slide.

The Sutton team has fine-tuned the final drive gear ratio from 3.55 in the CS850GT to 3.37 in the ‘R’ version to make each gear slightly shorter. This revision makes the car more eager at launch and when pushing out of a corner, while hard acceleration feels faster and more aggressive.

In addition to making the Sutton Mustang sharper on track, the enhancements are designed to improve off the line performance with the manual gearbox in mind. The track-tuned CS850R also replaces the Mustang’s MagneRide suspension with Pro Active shocks and linear springs to achieve sharper input and performance when cornering.

In addition to painted dual racing stripes, the new model features several colour-matched extras to enhance distinctiveness and individualisation. For example, the Sutton Mustang features Race Red brake callipers that match red interior stitching, piping, and front / rear seatbelts.

Clive Sutton, Founder and CEO: “Our bespoke Mustang programme is popular with customers looking for right-hand drive high-performance Mustangs that outperform almost anything else on the road. Customer feedback we’ve gathered from our GT Mustang enabled us to fine-tune our offering to deliver a quicker, better handling car that provides more driver feedback… and even more smiles!”

The company’s CS850GT Mustang was launched last year and is a comprehensive reworking of Ford’s 5.0-litre V8 muscle car. The model came to life following customer demand from drivers who were frustrated there was no right-hand drive Shelby GT500 for the UK market.

The output of the CS850GT and CS850R is boosted to 859PS (847bhp) – making them the UK’s most powerful new Mustangs – with almost double the 460PS (454bhp) of the stock Ford. The Sutton Mustangs boast a custom-tuned Whipple Supercharger, intercooler and a Quad Active XFORCE exhaust that together deliver 902Nm (665lb-ft) of torque, alongside the significant power boost. With absolute driver engagement in mind, the new levels of performance are accessed by a short-shifting six-speed manual transmission.

The upgraded front and rear anti-roll bars are carried over from the CS850GT, along with its enhanced bracing and new subframe components to complement the upgraded suspension of the CS850R. Both models feature custom Vossen 20-inch wheels, uprated DBA brakes and Hawk pads, adding to the model’s track-ready capabilities.

Visually, Sutton Mustangs feature completely reworked front ends that bring UK buyers a GT500-style appearance complemented by a new bumper lip, carbon fibre side rockers, and a carbon fibre rear valance that houses the quad exhausts. Colour-adjustable tri-bar headlights, plus LED side and rear lights complete the new look, while enhancing visibility.

The new CS850R is priced from £121,000 on-the road with a number of additional options available to personalise the car further and enhance its performance. For example, those looking to fully-exploit the new model’s track capabilities may opt for the Sutton carbon track spoiler, while those owners seeking the most distinctive style may opt to customise the interior colours to further individualise the car.
