The last part of mustang story

The second-generation Ford Mustang is a pony car that was manufactured by Ford from 1973 until 1978. It was introduced in showrooms during September 1973, in coupe and hatchback versions for the 1974 model year, in time for the 1973 oil crisis. The Mustang II had no common components with the preceding models and shared its platformwith the subcompact-sized Ford Pinto.

The third generation 

The 1979 Mustang was based on the longer Fox platform (initially developed for the 1978 Ford Fairmont and Mercury Zephyr). The interior was engineered to accommodate four people in comfort despite a smaller rear seat. Body styles included a coupé, (notchback), hatchback, and convertible. Available trim levels included L, GL, GLX, LX, GT (1982-1993), GTS, Turbo GT (1983–84), GT-350 (1983–84), SVO (1984–86), Cobra (1979–81,1993), Cobra R (1993), and Ghia.

The third generation mustang had two different body styles. From 1979 to 1986 the car had an angled back front clip and four headlights, known by enthusiasts as "Four Eyes." Then in the 1987 to 1993 model years, the front clip had a rounded-off shape known as the "aero" style. Also in 1986, engines featured EFI (electronic fuel injection) instead of carburetors. Other changes for the 1986 models included an upgraded 8.8-inch (224 mm) rear-end with four shock absorbers.

In response to slumping sales and escalating fuel prices during the early 1980s, a new Mustang was in development. It was to be a variant of the Mazda MX-6 assembled at AutoAlliance International in Flat Rock, Michigan. Enthusiasts wrote to Ford objecting to the proposed change to a front-wheel drive, Japanese-designed Mustang without a V8 option. The result was a major facelift of the existing Mustang in 1987, while the MX-6 variant had a last minute name change from Mustang to Probeand released as a 1989 model.

The forth gen mustang 

In November 1993, the Mustang debuted its first major redesign in fifteen years. Code-named "SN-95" by the automaker for 1994–1998, it was based on an updated version of the rear-wheel drive Fox platform called "Fox-4." The new styling by Patrick Schiavoneincorporated several styling cues from earlier Mustangs.^[41] For the first time since 1974, a hatchback coupe model was unavailable.

The base model came with a 3.8 OHV V6 (232 cid) engine rated at 145 bhp (108 kW) in 1994 and 1995, or 150 bhp (110 kW) (1996–1998), and was mated to a standard 5-speed manual transmission or optional 4-speed automatic. Though initially used in the 1994 and 1995 Mustang GT and Cobra, Ford retired the 302 cid pushrod small-block V8 after nearly 30 years of use, replacing it with the newer Modular 4.6 L (281 cid) SOHC V8 in the 1996 Mustang GT. The 4.6 L V8 was initially rated at 215 bhp (160 kW), 1996–1997, but was later increased to 225 bhp (168 kW) in 1998.^[42]

For 1999, the Mustang was reskinned with Ford's New Edge styling theme with sharper contours, larger wheel arches, and creases in its bodywork, but its basic proportions, interior design, and chassis remained the same as the previous model. The Mustang's powertrains were carried over for 1999, but benefited from new improvements. The standard 3.8 L V6 had a new split-port induction system, and was rated at 190 bhp (140 kW) 1999–2000, while the Mustang GT's 4.6 L V8 saw an increase in output to 260 bhp (190 kW) (1999–2004), due to a new head design and other enhancements. In 2001, the 3.8 L was increased to 193 bhp.^[43] There were also three alternate models offered in this generation: the 2001 Bullitt, the 2003 and 2004 Mach 1, as well as the 320 bhp (240 kW) 1999 and 2001,^[44][45] and 390 bhp (290 kW) 2003 and 2004^[46] Cobra (also the first Mustang to feature an independent rear suspension).

Fifth gen mustang

Ford introduced a redesigned 2005 model year Mustang at the 2004 North American International Auto Show, codenamed "S-197," that was based on the new D2C platform.Developed under the direction of Chief Engineer Hau Thai-Tang, a veteran engineer for Ford's IndyCar program under Mario Andretti, and exterior styling designer Sid Ramnarace,^[51] the fifth-generation Mustang's styling echoes the fastback Mustang models of the late-1960s. Ford's senior vice president of design, J Mays, called it "retro-futurism." The fifth-generation Mustang was manufactured at the Flat Rock Assembly Plant in Flat Rock, Michigan.

For the 2005 to 2010 production years, the base model was powered by a 210 hp (157 kW; 213 PS) cast-iron block 4.0 L SOHC V6, while the GT used an aluminum block 4.6 L SOHC 3-valve Modular V8 with variable camshaft timing (VCT) that produced 300 hp (224 kW; 304 PS). Base models had a Tremec T5 5-speed manual transmission with Ford's 5R55S 5-speed automatic being optional. Automatic GTs also featured this, but manual GTs had the Tremec TR-3650 5-speed.^[52]

The 2010 model year Mustang was released in the spring of 2009 with a redesigned exterior and a reduced drag coefficient of 4% on base models and 7% on GT models.^[53]The engine for base Mustangs remained unchanged, while GTs 4.6 L V8 was revised resulting in 315 hp (235 kW; 319 PS) at 6000 rpm and 325 lb·ft (441 N·m) of torque at 4255 rpm.^[54] Other mechanical features included new spring rates and dampers, traction and stability control system standard on all models, and new wheel sizes.

Engines were revised for 2011, and transmission options included the Getrag-Ford MT82 6-speed manual or the 6R80 6-speed automatic based on the ZF 6HP26 transmission licensed for production by Ford. Electric power steering replaced the conventional hydraulic version. A new 3.72 L (227 cu. in.) aluminum block V6 engine weighed 40 lb (18 kg) less than the previous version. With 24 valves and Twin Independent Variable Cam Timing (TiVCT), it produced 305 hp (227 kW; 309 PS) and 280 lb·ft (380 N·m) of torque. The 3.7 L engine came with a new dual exhaust; gasoline mileage increased to 19 city/31 highway mpg.[1]. GT models included a 32-valve 5.0 L engine (4951cc or 302.13 cu. in.) (also referred to as the "Coyote".) producing 412 hp and 390 ft-lbs of torque. Brembo brakes are optional along with 19-inch wheels and performance tires.^[55]

The Shelby GT500's 5.4 L supercharged V8 block was made of aluminum making it 102 lb (46 kg) lighter than the iron units in previous years. It was rated at 550 hp (410 kW; 558 PS) and 510 lb·ft (690 N·m) of torque.^[56]

For 2012, a new Mustang Boss 302 version was introduced. The engine had 444 hp (331 kW; 450 PS) and 380 lb·ft (520 N·m) of torque. A "Laguna Seca" edition was also available, which offered additional body bracing, the replacement of the rear seat with a steel 'X-brace' for stiffening, and other powertrain and handling enhancements.

In the second quarter of 2012, Ford launched an update to the Mustang line as an early 2013 model. The Shelby GT500 has a new 5.8 L supercharged V8 producing 662 hp (494 kW; 671 PS). Shelby and Boss engines came with a six-speed manual transmission. The GT and V6 models revised styling incorporated the grille and air intakes from the 2010–2012 GT500. The tail lights were changed to LED units and the decklid received a black cosmetic panel on all trim levels. The GT's 5.0 liter V8 gained eight horsepower from 412 hp (307 kW; 418 PS) to 420 hp (313 kW; 426 PS).
