In 1986, the Mustang received its first significant redesign since being introduced in 1978, incorporating both interior and exterior changes for the 1987 model year. The exterior design was reminiscent of the earlier SVO and gave the car more of an "Aero" look, in keeping with Ford's overall styling direction. With the end of the 1986 SVO, the models were now pared down to LX and GT. Taillights on the LX were slightly revised, while the GT now wore a specific louvered treatment. Rear quarter glass windows on LXs and GTs lost their louvered treatment and now sported a single piece of glass reading "Mustang" at the bottom. GTs retained foglights and new turbine style 15-inch (380 mm) wheels were introduced. LXs added the GT-specific alloys for 1985 and 1986 on new LX 5.0 models. This particular Mustang represents the longest run on any platform and the popularity of the Mustang remained high due to its low cost and high-performance. The 302 cu in (4.9 L), marketed as "5.0", Mustangs became popular with the
aftermarket performance industry.
[6] The V6 option was discontinued while the 2.3 L four-cylinder gained fuel injection, leaving only the 2.3 L four-cylinder and the
302 cu in (4.9 L) V8.
In 1989, Ford resources began to focus on the next Mustang, due to debut in late 1993.
[9] There would be few changes in the model line through its retirement in 1993. Most changes would be visual. For 1990, a limited run of 4,103 emerald green exterior, and white leather interior 5.0 LX convertibles, and a limited run of 5,897 silver exterior, and grey interior 5.0 GT hatchbacks were produced for a contest held by 7-Up, but the contest was cancelled at the last second. Similarly, for 1992 and 1993, three special-edition 5.0 LX convertibles were released in the spring. These models had with Vibrant Red exteriors with Oxford white leather interiors for 1992, Canary Yellow exterior with black or white leather interior, or Vibrant white exterior with white leather interior, for 1993.
