Ford Mustang S550: history, engines, versions and UK buying guide

The Ford Mustang S550 is the sixth-generation Mustang, built at Flat Rock, Michigan, from August 2014 to April 2023 for the 2015 to 2023 model years. It was the first Mustang range with independent rear suspension on every version and the first built with right-hand drive at the factory. It was also the first Mustang Ford offered in Britain since the Mustang II of 1975, which was converted to right-hand drive here. UK cars came with a 2.3-litre EcoBoost four-cylinder or the 5.0-litre V8 GT, later joined by the Bullitt and Mach 1; the Shelby GT350 and GT500 were not in Ford’s European range.

Ford sold 633,000 sixth-generation Mustangs in 146 countries between the start of exports in 2015 and the end of 2019, and the car was the world’s best-selling sports coupé for five years running, according to Ford’s April 2020 sales release. In the UK, 13,561 Mustangs were first registered from 2015 to 2023, and 10,619 built in those years were still on the DVLA record at the end of 2025 (our count from Department for Transport tables, below).

History of the Ford Mustang S550

S550 is the code for the sixth-generation Mustang’s platform, which replaced the S197 Mustang of 2005 to 2014 with a new body, new suspension front and rear and a choice of three engines, and Ford designed it from the start to be sold in Europe and Asia as well as America. Its chief engineer was Dave Pericak, who took the 2012 Boss 302 as the benchmark: “We already set a very high standard for Mustang’s dynamics with Boss 302, and our goal was to go above and beyond that with this new car,” he said in Ford’s launch release of 5 December 2013. The Boss 302’s 444bhp V8 had forged pistons and connecting rods, revved to 7,500rpm and had been tested to 8,400rpm; a 1,500-mile test of a Boss 302 Laguna Seca published by SkiddMark in August 2011 called it “one of the finest normally aspirated V8s on the market today”.

The reveal of 5 December 2013

Ford showed the new car on 5 December 2013 in six cities on four continents at once, four months before the Mustang’s 50th anniversary on 17 April 2014; every 2015 car carried a “Mustang – Since 1964” badge on the dashboard. Ford’s release said the car would be sold “in key parts of Europe and Asia” for the first time. Ford quoted more than 420 horsepower and 390 lb ft for the V8, more than 305 horsepower and 300 lb ft for the new EcoBoost and at least 300 horsepower for the 3.7-litre V6.

Ford’s release listed a lower, wider stance with a reduced roof height, a sloping fastback, three-dimensional tri-bar tail lamps and a new version of the Mustang’s “shark-bite” front. At the European unveiling in Barcelona the 2.3-litre EcoBoost was quoted at 306bhp and 407Nm, “more than a match for BMW’s 335i”, against 420bhp and 529Nm for the 5.0-litre V8, according to a SkiddMark report of 5 December 2013; the geometry, springs, dampers and bushes had been tuned “to suit European tastes”, the European car was to get touchscreen control, an 8-inch navigation screen and a 12-speaker stereo, and pricing, specification and the launch date were still to come.

Production at Flat Rock and right-hand drive

Production began at Flat Rock Assembly Plant in August 2014, and in 2015 Ford started building right-hand-drive Mustangs there for more than 25 markets that drive on the left, according to Ford’s 60-year Mustang timeline. Earlier British Mustangs had been imports or conversions: in 1975 Ford sold a right-hand-drive Mustang II for Britain, built with left-hand drive and converted here, the same timeline records.

Ford opened UK order books in January 2015, with prices from £28,995 for the EcoBoost, GTSpirit reported on 21 January 2015. By August 2015 almost 2,000 UK orders had been taken, the first deliveries were due from November, and prices were £29,995 for the EcoBoost and £33,995 for the V8, The Manufacturer reported on 25 August 2015. Of those buyers, 80% chose the fastback, 70% the 416PS V8 over the 317PS EcoBoost and 55% the six-speed manual; Race Red was the top exterior colour at 23%, and every UK car had a Thatcham Category One alarm.

The 2018 facelift

The facelifted car went on sale in Europe in 2018. Ford’s April 2018 release described “a more athletic exterior” and an upscale interior; the changes included a 10-speed automatic in place of the six-speed, optional MagneRide adaptive dampers, a 12-inch digital instrument panel and a V8 raised to 450PS, while the EcoBoost dropped to 290PS. Ford’s 2018 European technical specification lists both engines and both gearboxes. What Car? put the EcoBoost’s cut down to new emissions rules. By the 2022 model year Ford’s European specification listed only the V8 GT and the Mach 1.

End of production and the S650

Production began at Flat Rock in August 2014, Automotive Fleet reported on 28 August, and the last S550, an Oxford White EcoBoost, was built on 6 April 2023, FordMuscle reported. Production of the seventh-generation S650 began there on 1 May 2023, “just a few weeks after 2023 Mustang production ended”, Ford Authority reported that day. The S650 kept the 2.3-litre EcoBoost and the 5.0-litre Coyote V8 in revised form.

Ford Mustang S550 design and engineering

The S550 is a two-door, four-seat fastback or convertible with a welded steel body, an aluminium bonnet and front wings, the engine at the front and drive to the rear wheels through a limited-slip differential. Ford’s 2018 European figures give a length of 4,789mm, a width of 1,916mm without mirrors, a 2,720mm wheelbase and a 408-litre boot in the fastback (332 litres in the convertible).

Body and independent rear suspension

Ford’s 2013 release described the S550 as lower and wider than the S197, with a lower roof, wider rear wings and track, a more steeply raked windscreen and rear window, and a convertible roof that lowered twice as fast as before. At the front a new perimeter subframe and double-ball-joint MacPherson struts made room for bigger brakes; at the rear an integral-link independent suspension with aluminium knuckles replaced the S197’s live axle. In the UK the V8 GT came with Brembo six-piston front calipers on 380mm discs.

Interior and technology

The dashboard has a metal-finish span with three round vents and toggle switches below the screen; Ford called it an “aviation-inspired cockpit” and said the boot would take two golf bags. Every car had push-button start and Ford’s SYNC infotainment, and automatics had shift paddles on the steering wheel. Selectable Drive Modes changed steering weight, throttle response, gearbox and stability control. The V8 added launch control and an electronic line-lock that holds the front brakes for a burnout. From 2018 the optional 12-inch digital instruments replaced the analogue dials.

Ford Mustang S550 engines and specs

European S550s had two engines: the 5.0-litre Coyote V8 in the GT, Bullitt and Mach 1, and the 2.3-litre EcoBoost turbocharged four-cylinder. North American buyers could also have a 3.7-litre V6, and the Shelby models had their own 5.2-litre V8s. The table gives Ford’s European figures for the facelifted cars.

Sources: Ford’s European technical specifications, 2018 (PDF) and 2022 (PDF). *Ford gave these as anticipated figures. Kerb weights include a 75kg driver.

5.0-litre Coyote V8

The V8 is Ford’s Coyote, an all-aluminium, four-cam, 32-valve engine with variable timing on both camshafts. In the 2015 to 2017 cars it displaced 4,951cc and made 416PS in Europe; Ford’s 2016 US specification rates it at 435 horsepower at 6,500rpm and 400 lb ft at 4,250rpm. For 2018 it grew to 5,038cc with a 12.0:1 compression ratio and twin injection (port and direct), and power rose to 450PS at 7,000rpm with 529Nm. GT and Bullitt manuals use a Getrag MT82 six-speed, the Mach 1’s manual is a Tremec TR-3160, and the automatic was a six-speed until 2017 and the 10-speed 10R80 from 2018.

2.3-litre EcoBoost

The EcoBoost is a 2,261cc turbocharged four-cylinder with direct injection and the exhaust manifold cast into the cylinder head. It made 317PS at launch in Europe and 290PS from 2018, when its torque was 440Nm at 3,000rpm, and Ford quoted a service interval of 16,000km (10,000 miles) for both engines. At the end of June 2026, 2,123 Mustangs on the UK record were registered under EcoBoost model names.

3.7-litre V6

The 3,727cc V6 was the base engine in North America, rated at 300 horsepower and 280 lb ft in 2016. It was never part of Ford’s UK range, which listed only the EcoBoost and the V8 from the first price list in 2015.

How fast is a Mustang S550?

The quickest S550 to 62mph in Ford’s European figures is the facelifted V8 GT automatic, at 4.3 seconds, and the highest top speed Ford quotes for a European car is the Mach 1 manual’s 267km/h (166mph). The most powerful S550 is the Shelby GT500, at 760 horsepower, and the highest-revving is the GT350, whose flat-plane V8 redlines at 8,250rpm.

Mustang S550 versions and special editions

Beyond the EcoBoost and the GT, Ford built four high-performance versions of the S550: the Shelby GT350, the Shelby GT500, the Bullitt and the Mach 1. Of these, Ford’s European releases and specifications list only the Bullitt and the Mach 1.

Shelby GT350 and GT350R

Ford showed the Shelby GT350 at the Los Angeles motor show in November 2014 with a 5.2-litre V8 that had a flat-plane crankshaft, “the first to any Ford road car engine”, CAR magazine reported. Ford gave its output only as more than 500 horsepower until June 2015, when a dyno sheet showed 526 horsepower, 429 lb ft and an 8,250rpm redline, Guide Auto Web reported. The car had the first MagneRide dampers on a Ford, a carbon-fibre reinforcement in the grille opening, and two-piece 394mm front and 380mm rear discs with six-piston Brembo calipers at the front, according to Ford’s May 2015 release. CAR noted a lip spoiler on the boot lid. The GT350R had carbon-fibre wheels with Michelin Pilot Sport Cup 2 tyres as standard, about 50lb lighter as a set than the GT350’s alloys and tyres, and Ford said it was the first major car maker to offer them.

Shelby GT500

The GT500 joined the range for the 2020 model year. Ford showed it at the Detroit show in January 2019 with “at least 700 horsepower” and announced in June 2019 that its supercharged 5.2-litre cross-plane V8 made 760 horsepower and 625 lb ft, Hagerty reported on 19 June 2019. It used a Tremec seven-speed dual-clutch gearbox and 16.5-inch front discs, with an optional Carbon Fiber Track Pack.

Bullitt

The Bullitt marked 50 years since Steve McQueen’s 1968 film. It made its European debut at the Geneva show on 5 March 2018 after a world debut in Detroit, and production for Europe began that June, Ford announced at the show. Its V8 had the GT350’s Open Air Induction System, intake manifold and 87mm throttle bodies for 464PS and 529Nm, with a six-speed manual and rev-matching, and buyers could choose Recaro sports seats. It came in Shadow Black or Dark Highland Green with 19-inch Torq Thrust-style wheels, red Brembo calipers, the 12-inch digital instruments, a white cue-ball gear knob and a numbered plaque on the dashboard; the first car, VIN 001, raised $300,000 for charity. At the end of 2025, 678 Bullitts built from 2018 to 2020 were on the UK record, by the DfT’s table VEH0124.

Mustang Mach 1

The Mach 1 arrived in 2021. Ford’s European specification gives it 460PS at 7,250rpm, the Shelby GT350’s induction system and 87mm throttle body, the GT350’s air-to-oil engine cooler, extra cooling for the gearbox and rear axle, MagneRide as standard and 120mm of ground clearance against the GT’s 144mm. It could have the six-speed manual or the 10-speed automatic; 521 Mach 1s built from 2021 to 2023 were on the UK record at the end of 2025.

UK special editions

Ford UK also sold trim editions of the GT. The DfT’s licensing table VEH0120 lists 148 Mustang Shadow Editions and 166 55 Editions on the UK record at the end of June 2026. Ford’s timeline also records a modern California Special in 2016, and the 2015 model year had a 50 Year Limited Edition, which appears in the auction prices below.

How safe is the Mustang S550?

Euro NCAP gave the Mustang two stars in January 2017 and three stars in a reassessment dated July 2017. In the first test, published on 25 January 2017, the driver’s and passenger’s heads “bottomed out” their airbags in the frontal offset crash, the rear passenger slid under the lap belt, the rear belts, which had neither pretensioners nor load limiters, gave poor chest protection, and the car had no autonomous emergency braking. Ford told Euro NCAP that orders placed after May 2017 would get an updated car with Pre-Collision Assist, pedestrian detection and Lane Keeping Aid as standard; the reassessment, for cars ordered from July 2017 with a revised restraint system, gave three stars, using the earlier crash tests because the structure was unchanged.

The S550 Mustang in motor racing

The S550’s biggest race win came at the 2019 Bathurst 1000, where Scott McLaughlin and Alexandre Prémat won in DJR Team Penske’s number 17 Mustang. McLaughlin held off Shane van Gisbergen in a one-lap dash after a late Safety Car, giving the Dick Johnson Racing squad its first Bathurst win since 1994, Motorsport.com reported on 13 October 2019; he left the race with a 633-point lead in the Supercars championship, according to Team Penske. In America Billy Johnson and Scott Maxwell drove the Shelby GT350R-C, a racing version of the GT350R, to its first win at Daytona, in the Continental Tire SportsCar Challenge race of 29 January 2016, with a second GT350R-C in second place, Ford announced.

How many S550 Mustangs were made and sold?

Ford’s sales releases give 633,000 sixth-generation Mustangs sold worldwide from 2015 to the end of 2019, and almost 60,000 sold in Europe by the end of 2020. On the IHS Markit registration data Ford quotes, the Mustang was the world’s best-selling sports coupé every year from 2015 to 2020, and Ford called it the best-selling sports car in 2016, 2019 and 2020.

By the end of 2017 Ford had sold 418,000 sixth-generation Mustangs worldwide. In 2020 the United States took about three-quarters of all Mustang sales.

How many Mustangs were sold in the UK?

In the UK, 13,561 Mustangs (not counting the electric Mach-E) were registered for the first time between 2015 and 2023, by our count from the DfT’s table VEH0160. The count includes some imported older Mustangs registered here for the first time, but in these years most were S550s; registrations peaked at 3,469 in 2016, the first full year of right-hand-drive deliveries.

Source: Department for Transport, VEH0160 (UK), read 27 October 2026. At the end of 2025 the DfT’s table VEH0124 showed 10,619 Mustangs built from 2015 to 2023 on the UK record, 9,389 licensed and 1,230 declared off the road (SORN).

Buying a used Mustang S550 in the UK

UK cars came with the Performance Pack as standard, Fast Car notes, and the main choices are V8 or EcoBoost, manual or automatic, and before or after the 2018 facelift. Left-hand-drive imports, including V6 cars and Shelbys, are on sale too, and they sit outside the UK-car prices below.

Which S550 to buy

The 2018 facelift brought the 450PS engine, the 10-speed automatic, optional MagneRide dampers and digital instruments, and the active-valve exhaust; it also changed evo’s view of the chassis: in the June 2018 test (issue 247) Stuart Gallagher wrote that with Michelin Pilot Sport 4S tyres in place of Pirelli P Zeros and the £1,600 MagneRide option “gone is the float and wobble of the old car”. The V8 is the choice of most British buyers: it took 70% of the 2015 UK orders, and only about one in five S550-era Mustangs on the UK record is an EcoBoost.

Is the Mustang S550 reliable?

Fast Car’s January 2024 buying guide finds few serious mechanical faults in the S550, and evo’s Richard Meaden called it “mechanically bombproof” in 2015. The guide lists oil-cooler failures on early 2015 and 2016 V8s, a light ticking from many Coyote engines that Ford considers normal, a clutch-pedal switch on pre-June 2016 manuals that could stop the engine starting, shift forks on some early 2018 MT82 gearboxes, wheel bearings, air-conditioning condensers, and panel gaps and paint on pre-facelift cars. Adam Towler, who ran a facelifted GT for evo through 2019, found that the car went into limp mode after a few fast laps of Goodwood on a summer’s day, which he traced to a temperature sensor on the rear differential (evo 271, March 2020).

Recalls in the UK

The DVSA recalls file lists the S550’s UK recalls with the build dates they cover. They include a fire risk from the battery cable running too close to the exhaust manifold on 1,255 cars built in 2015 (R/2016/022); corrosion of the front seat-belt pretensioner cables on 7,414 cars built between late 2014 and mid-2021 (R/2025/530), for which parts were not yet available when it was issued; a rear-view camera fault on 8,525 cars built from July 2015 to December 2018 (R/2026/213); a brake warning lamp that may not light on 2,456 cars built from 2019 to 2022 (R/2023/342); and a fuel-pump software update on 774 cars from 2021 and 2022 (R/2025/369).

Running costs: tax, fuel and servicing

Road tax depends on the registration date. A car first registered before April 2017 is taxed on its CO2 figure, and What Car? notes that the GT falls in the top band; that band, over 255g/km, costs £790 a year, according to GOV.UK. A car registered from April 2017 pays the standard rate of £200, plus £440 a year for five years if its list price was over £40,000; evo’s used guide gives £43,000 as the starting price of a facelifted V8. Ford’s 2022 figures give the V8 11.2 to 12.1 litres per 100km (23 to 25mpg) on the WLTP cycle, and the service interval is one year or 10,000 miles.

Ford Mustang S550 prices and values

New, a UK Mustang cost from £28,995 when order books opened in January 2015, and a facelifted V8 with options could pass £45,000: the evo long-term GT of 2019 came to £45,625. A V8 cost £33,995 new in August 2015; three UK auction results in OUTLAW 8’s records for the year to 26 October 2026, all 2016 V8 GTs sold through Car & Classic, made £22,000, £26,500 and £27,751.

These are the medians of S550s sold at auction in the US over the same 12 months, from OUTLAW 8’s records of sales at Bring a Trailer, Mecum, Cars & Bids, Barrett-Jackson and others; tuned, racing and film cars are left out.

Source: OUTLAW 8 auction records, sold cars only, one sale per VIN; a median of an even number of sales is the mean of the middle two. Two Mach 1s sold, for $46,800 and $55,500.

Rivals and reception

In America the S550 competed with Chevrolet’s Camaro and Dodge’s V8 coupés: when Ford rated the GT500 at 760 horsepower, Hagerty placed it between the Camaro ZL1’s 650 horsepower and the 797 of Dodge’s Redeye models. In Britain evo’s Adam Towler set his facelifted GT’s £45,625 price, with options, against the £52,000 of a Toyota Supra, and evo compared the car’s weight with a BMW M440i’s.

What the press said

Richard Meaden wrote in evo 211 (August 2015) that it “feels mechanically bombproof and offers great value for money, at least against new European metal”. Jethro Bovingdon, in evo 219 (March 2016), found that on the roads evo loves “it feels too heavy, the body control is compromised too easily”, and added that “there’s a really good car lurking within the Mustang”. Adam Towler, after eight months with a facelifted GT on evo’s fleet, wrote: “I really miss mine.”
