The development of the Mustang began in 2009 under the direction of the chief engineer Dave Pericak and exterior design director Joel Piaskowski.

After four years of development, Ford debuted the Mustang at numerous online media events in December 2013, preceding its public unveiling at the Detroit Auto Show in January 2014.

The sixth generation marked the first Mustang to be marketed globally, introducing factory-produced right-hand-drive models alongside the traditional left-hand-drive versions.

[25] Early in the development process, a decision was made to equip this generation with an independent rear suspension (IRS), which had previously been standard on the 1999–2004 SVT Cobra.

[32][33] At the Flat Rock plant, official series manufacture of the sixth-generation Mustang was initiated on August 28, 2014;[34][35] a week before this, right-hand drive models began testing.

[44] Ford incorporated high-strength steel into the chassis and used aluminum for the front fenders and hood, making the new Mustang both stronger and lighter than its predecessor.

This new top, developed in partnership with supplier Webasto, is completely electric, making it quieter, slimmer, and simpler than the previous electro-hydraulic system.

[75] Optional features include Sirius XM satellite radio, the MyFord Touch—replaced by the Sync 3 in 2016—infotainment system with an eight-inch touchscreen, support for Apple CarPlay and Android Auto (both introduced in 2017), and enhanced voice control.

The Mustang's EcoBoost engine spins its low-mass turbine to reduce lag and minimize efficiency and power loss from backflow into other cylinders.

[97] Between the model years 2020 and 2023, Ford produced a High Performance Package of the EcoBoost engine, increasing its power output to 330 horsepower (250 kW).

[113] The interior design remained familiar but features updates, including a revised instrument panel and added soft-touch surfaces on the center console.

[147][151] The GT500's scoops and vents are larger to meet the increased cooling demands of its more powerful engine and transmission, as well as its enlarged brakes, which now feature 16.5-inch (420 mm) front rotors for improved heat dissipation.

The Carbon Fiber Track Pack, which includes 20-inch carbon-fiber wheels, aerodynamic enhancements, and Michelin Pilot Sport Cup 2 tires.

[6] The Shelby Mustang's interior closely resembles that of the standard model, sharing design elements and similar passenger and cargo space.

Changes included a choice of two special edition body colors based on 1964 model year colors (Wimbledon White and Kona Blue), louvered rear quarter-windows with layered sheets of glass, cashmere-stitched leather-wrapped steering wheel, cashmere-stitching in instrument panel, shifter boot, center armrest, door inserts and seats; exclusive two-tone cashmere and black leather upholstery, Mustang 50 Year logo on the seat backs, loop-carpet floor mats with cashmere stitching and suede binding, 19-inch (9.0/9.5-inch front/rear) alloy wheels with unique Y-spoke design, 255/40R front tires, 275/40R rear tires.

Wimbledon White and Kona Blue will no longer be available exterior colors on the Mustang after the 50 Year Limited Edition's discontinuation when the model sells out.

A "one of one" convertible version of the 50 Year Limited Edition Mustang was raffled off for charity on the "Woodward Dream Cruise" on August 16, 2014, with the proceeds benefitting the National Multiple Sclerosis Society.

Blue and yellow rear-end graphics mimic the tail livery of early-production examples of the F35 fighter jet, as does the gold tint on its windows.

The car sits on lowered Eibach springs and custom black and yellow Forgiato 21-inch wheels, while the exhaust system was modified with larger, ceramic-coated cans.

The interior of the car features mix of black and yellow parts, with additions including Recaro racing seats, a modified instrument cluster, custom audio system, and sill plates, as well as F-35 Lightning II embroidery on the floor mats, door panels, and seatbacks.

[165] Unveiled at the 2014 Los Angeles Auto Show, the Rocket was a variety of the Mustang modified by Henrik Fisker, a Danish automobile designer.

The Black Label also features a body kit, including a completely redesigned front fascia, axial grill, hood, side skirts, wing, and rear diffuser.

Performance wise, the Shelby GT was outfitted with a cold air intake that comes standard with the car good for a small increase in horsepower.

[175] Significant engineering innovations result in weight savings, aerodynamic improvements to benefit on-track performance; Ford introduced carbon fiber wheels as standard equipment on the Shelby GT350R Mustang.

Items removed include air conditioning, the stereo system, rear seats, trunk floorboard and carpet, backup camera, and emergency tire sealant and inflation kit.

It includes 800+ hp, lowered and tuned suspension and a 13.6 kg (30 lb) weight reduction via an ultra-light, vented dry carbon fiber hood.

It features a larger supercharger pushing more than 900 horsepower, a vented dry carbon fiber hood, one-piece forged mono-block wheels, Borla exhaust, improved suspension and a reworked interior.

Mark Rushbrook, the CEO of Ford Performance Motorsports, says that the Cobra Jet 1400 was an opportunity to develop electric powertrains on an existing, popular sports car.

[185] Euro NCAP tested a LHD (Left Hand Drive), European version of the 2-door coupe variant on a 2017 registration and earned 2 stars out of 5.

[194] The Shelby Mustang GT350R-C, the race version of the GT350R, was campaigned by Multimatic Motorsports in the Continental Tire Sports Car Challenge during the 2015 and 2016 seasons, winning the 2016 drivers' and constructors' championships.
