The second evolution of the Third Generation Ford Mustang debuted for the 1987 model year. Enthusiasts commonly refer to this second evolution of the Third Generation Mustang as the "Aero" or “Aeronose” due to its sleeker, more aerodynamic appearance. These updated Mustangs were available in Hatchback (a/k/a fastback), Coupe (a/k/a notchback), Convertible, and T-top body style, although the later was  discontinued in 1988. Engine options were reduced to either a 2.3L Inline 4 or the 5.0L V8, paired to manual or automatic transmissions, with both options sending drive to the rear wheels. Many notable variants were built for the "Aero," including the GT, SSP, SVT Cobra, and the high performance SVT Cobra R. Production of the Third Generation Mustang lasted until 1993, when it was replaced by the Fourth Generation Ford Mustang.
