reverse the sales collapse of the Ford Thunderbird and Mercury Cougar (now solely a coupe), Ford redesigned the two coupes with radical new aerodynamic bodystyling. The revision effectively tripled the size of the Lincoln model range while eliminating the duplication of several Ford/Mercury vehicles (the Ford Fairmont/Granada and Mercury Zephyr/Cougar sedan and wagon); the mid-size Fairmont/Zephyr were replaced by the compact Ford Tempo/Mercury Topaz for 1984 and the Cougar reverted to its coupe-only bodystyle. SN-95 By the early 1990s, the Ford Mustang had become the sole model produced on the Fox platform. For the 1994 model year, as the Mustang underwent a major redesign (under the body family program code name Fox-4), the Fox platform itself saw major changes to its architecture. As part of the upgrade, most of its parts were redesigned carrying over only the floor pan and front suspension cross member with major changes to the suspension and improvements to noise, vibration, and harshness (NVH); the updated Mustang-specific platform became known as the SN-95 platform. The 2003–2004 Mustang SVT Cobra became the ultimate development of the Fox/SN95 platform, with a 390 hp supercharged 4.6L DOHC V8. The SN95 platform would be produced for 11 years, extending the life of the Fox platform to 26 years of production. For 2005, the Mustang was completely redesigned, using the all-new Ford D2C platform. Discontinuation As the company entered the 1980s, Ford became part of a growing trend among automobile manufacturers using front-wheel drive in its vehicles. As part of the 1983 changes to the Ford product range, the Ford Fairmont and Mercury Zephyr were phased out in favor of the front-wheel drive Ford Tempo/Mercury Topaz, introduced as 1984 models and based on a long-wheelbase variation of the Ford Escort platform. Introduced as 1983 models, the Ford LTD and Mercury Marquis were replaced after the end of their short 1986 model year run by the Ford Taurus and Mercury Sable. As the Lincoln Continental shifted to front-wheel drive after the 1987 model year, sedan production of the Fox platform ended. For 1989, Ford moved the Thunderbird and the Mercury Cougar to the all-new MN12 platform; while still rear-wheel drive, the new chassis introduced a number of suspension advances over the Fox platform. As the Lincoln Mark VII was replaced by the Mark VIII for 1993, the Ford Mustang became the sole Fox-platform produced by Ford. Vehicles In total, fifteen distinct vehicles
