The sixth generation Mustang was unveiled on December 5, 2013, in Dearborn, Michigan; New York, New York; Los Angeles, California; Barcelona, Spain; Shanghai, China; and Sydney, Australia. The internal project code name is S-550.
Changes include a body widened by 1.5 inches and lowered 1.4 inches, a trapezoidal grille, and a 2.75-inch lower decklid, as well as new colors. The passenger volume is increased to 84.5 cubic feet, the wheelbase is still 8 ft. 11.1 in. (107.1 in.), and three engine options are available: a newly developed 2.3 L EcoBoost 310 hp four-cylinder introduced to reach high tariff global markets like China, 3.7 L 300 hp V6, or 5.0 L Coyote 435 hp V8, with either a Getrag six-speed manual or six-speed automatic transmission with paddle shifters.
A new independent rear suspension (IRS) system was developed specifically for the new model. It also became the first version factory designed as a right hand drive export model to be sold overseas through Ford new car dealerships in right hand drive markets. During this model year, left hand drive versions were expanded to new export markets.
The 2018 model year Mustang was released in the third quarter of 2017 in North America and by 2018 globally. It featured a minor redesign to the exterior. The 2018 Mustang engine line up was revised. The 3.7 L V6 was dropped and the 2.3 L I4 Ecoboost (direct-injection turbocharged) engine now serves as the base power plant for the Mustang, producing 310 hp (231 kW) and 350 lb⋅ft (475 N⋅m) of torque when using 93-octane fuel. The 5.0 L V8 gets a power increase to 460 hp (343 kW) and 420 lb⋅ft (569 N⋅m) of torque. The automatic transmission in both engines is now a ten-speed Ford 10R80. In January 2018, Ford displayed a prototype of the special edition 2018 Bullitt model, to be released in the summer; this vehicle commemorated the 50th anniversary of the movie Bullitt that helped attract interest in the marque.
For the 2019 model year, Ford revised many components on the 2019 Shelby GT350 including stickier Michelin Pilot Sport Cup 2 tires along with steering and suspension components.
The 2020 model year saw the re-introduction of the GT500. The 2020 GT500 includes a hand-built 5.2-liter "Predator" aluminum-alloy V8 engine with a 2.65-liter roots-type supercharger. The Shelby GT500 produces 760 hp (567 kW; 771 PS) and 625 lb⋅ft (847 N⋅m) of torque. The GT350 was discontinued at the end of the 2020 model year.
For the 2021 model year, Ford re-introduced the Mach 1 after a 17-year hiatus. The 2021 Mach 1 utilizes the current Coyote 5.0 L engine with GT350 parts, including the intake manifold, increasing performance to 480 hp (358 kW) at 7,000 rpm and 420 lb⋅ft (569 N⋅m) at 4,600 rpm in addition to utilizing the GT350's lightweight Tremec six-speed manual transmission, oil-filter adapter, engine oil cooler, and front and rear subframe. The Mach 1 also utilizes parts from the GT500, including the rear axle cooling system, rear toe link, and rear diffuser.
