Clive Sutton Mustang CS850GT Is The UK’s Most Powerful Pony Car

London-based supercar dealer Clive Sutton has been producing ultra-powerful Ford Mustang models for years now, offering up outputs in the 700 to 800+ horsepower range. Of course, these ultimate pony cars aren’t exactly cheap, even on the used car market, but good things rarely are. Regardless, these purveyors of power just keep extracting more from Ford’s legendary pony car and have reached a new pinnacle with the Clive Sutton Mustang CS850GT.

The dealer points out that the purpose behind the Clive Sutton Mustang CS850GT is to address frustrations that the Ford Mustang Shelby GT500 isn’t available in right-hand-drive configuration. Thus, the CS850GT was designed to be even more powerful than Ford’s 5.2L Predator V8-powered machine, which wasn’t terribly hard to accomplish.

Clive Sutton managed to extract a significant 847 horsepower (859 PS) and 665 pound-feet of torque (902 Nm) from Ford’s 5.0L Coyote V8 – making it the UK’s most powerful Mustang and nearly doubling the car’s stock output. This was accomplished mostly via a custom Whipple supercharger, which is paired with a massive intercooler and a quad active XForce exhaust.

The blown V8 is backed up by the requisite six-speed manual gearbox, which has been treated to a short-throw shifter for an old-school muscle car experience. Clive Sutton has also addressed the suspension of the new CS850GT, giving it upgraded front and rear anti-roll bars, subframe components, DBA brakes with Hawk pads, and custom 20-inch Vossen wheels.

In the looks department, the CS850GT stands out from other Mustang models on UK roads thanks to its GT500-like front end, front lip, carbon fiber side rockers and rear valance, LED lighting, and tri-bar headlights with a variety of custom colors to choose from. Inside, the cabin has been upgraded with a red billet aluminum start button, carbon fiber dash, Sutton performance steering wheel, a combination of leather and Alcantara, and accent stitching. Customers can choose their own color combinations for a truly custom appearance, too.

As one might expect from a bespoke pony car such as this, other goodies can be added to suit just about anyone’s taste, including an optional Sutton track performance rear spoiler. The price for all this GT500-beating goodness is £115,000 ($159,602 USD) and can be configured to one’s personal specification here.

Brett's lost track of all the Fords he's owned over the years and how much he's spent modifying them, but his current money pits include an S550 Mustang and 13th gen F-150.

    I’ve driven equipment that has right side steering, but it was still driven from the right lane on two-way roads. I’ve often wondered what driving from the left (wrong?) side and shifting with y’all’s left hand would be like. Is throttle/brake still done with the right foot and clutch with the left foot?

    1. Alex

      Yes the arrangement is exactly the same for the pedals, just shifted over. I drive my LHD GT500 Super Snake in the UK without any issues at all.

  2. Mortimer Duke

    Ludicrously expensive relative to the actual component cost which would perform far if built upon a Mach1 foundation.

  3. Peter

    Where you gonna use this most powerful pony car on UK roads then ?

    1. Ray

      Bragging rights , that’s the most this car gives to its owner

  4. Roy Chile’s

    That’s a lot of money for a SC Coyote 5.0 with a 6 spd transmission

  5. Blather

    Yeah, but it has the steering wheel on the WRONG side!

  6. Mark L Bedel

    I think all these companies that engineer and produce these upgraded ‘stangs are cool, but I always ask the question, how long will they hang together? When spending that kind of $$$, it would be nice to have some assurance of a reasonable life. Define reasonable…? I guess it’s in the eye of the beholder.

  7. Jean-Francois Rivard

    I agree with the prior post. I don’t see anything substantial describing a beefed-up transmission, clutch, half-shafts, or improved cooling ? For example, the Stock GT500 is capable of dissipating up to 230 kilowatts of heat energy, enough to heat a dozen homes.

    Any decent tuner or web savvy DIY guy can slap a supercharger on a late model Coyote and get over 800 hp. The hard thing is make it work for more than 10-20 seconds without overheating or grenading drive train parts on a race track, the only safe place to really use that much HP.
