First Generation (1964 ½ - 1973): On April 17th, 1964 the Ford Mustang was introduced. The first generation of this iconic car ran through 1973. This includes vehicles such as the classic Shelby Mustang lineup, Boss Mustangs, K-Code Mustangs, the “Bullitt” Mustang GT-390 Fastback, the original Cobra Jets, and all the other Mustangs most folks consider “classic”.
Second Generation (1974-1978): The second generation of Mustang is often coined the “Pintostang” generation because the cars were based on the Ford Pinto platform. Smaller and more fuel efficient, this generation featured the likes of the Mustang II, the Mustang Cobra II, and the King Cobra Mustang. It was also the first generation to feature a 4-cylinder engine.
Third Generation (1979-1993): This generation of Mustang encompassed more years than any other generation in the history of the car. Coined the “Fox Body” Mustang, this car was based on the Fox platform. It was light, European in design, and loaded with power. Does 5.0 GT mean anything to you? This generation of Mustang was also known for its powerful 5.0L V-8 engines.
Fourth Generation (1994-2004): In 1994, the Mustang’s 30th anniversary, Ford introduced the SN95 Mustang. It was based on the SN-95/Fox4 Platform. The fourth generation Mustang was larger than the previous generation and was engineered to be stiffer in design. In 1996 the popular 5.0L engine was replaced with a 4.6L modular V-8 engine. This generation spawned the “New Edge” line of Mustangs in 1999. Although the cars looked different, they were still based on the SN-95 platform.
Fifth Generation (2005-2013): In 2005 Ford introduced a new Mustang. Based on the D2C platform, this Mustang harkened back to the styling cues that adorned first generation Mustangs. The Mustang was longer than the previous generation and featured modern amenities such as GPS Navigation, heated leather seats, and satellite radio. This generation also saw the return of the Shelby Mustang when Carroll Shelby brought back the GT500 Mustang and the GT500KR. In 2009 Ford introduced a more powerful 2010 Ford Mustang. Although the car features numerous changes inside and out, it is still based on the D2C platform. In 2011 Ford brought the 5.0L engine back in the GT model, and produced a a 3.7L Duratec 24-valve V6 powered Mustang that produces 305 hp and 280 ft.-lb. of torque.
Sixth Generation (2014-2015): The sixth generation of the Ford Mustang, designated "S550", debuted on Dec. 5, 2013. It will be the Mustang's 50th year on April 17, 2014. This new Mustang is a fresh design, leaving behind the last generation's retro theme. Development of the S550 Mustang began in 2009 under chief engineer Dave Pericak and (from late 2009) exterior design director Joel Piaskowski, shortly after the updated S-197 went on sale for the 2010 model year.
