(詳細はFord from 1978 to 1993. Built on Ford’s widely used Fox platform, it evolved through a number of sub-models, trim levels, and drivetrain combinations during its production life. It underwent updates for 1987, and for a time seemed destined for replacement with a rebadged import before company executives were swayed by consumer opinions. Enthusiasts group the generation into two segments: the 1979-1986 cars, with their quad headlight arrangement, and the 1987-1993 cars, with their "no-grille" (aero) front fascia styling. Production ended with the introduction of the fourth-generation Mustang (SN-95) for the 1994 model year. == 1979–1982 == The new 1979 model year Mustang was based on the larger Fox platform, initially developed for the Ford Fairmont and Mercury Zephyr twins that debuted in 1977. The larger body meant the interior was restyled with more space for four passengers, even with the smaller back seat, as well as a larger capacity trunk and a bigger engine bay. Body styles included a coupe (notchback) and hatchback (fastback). The only trim level available over the base model was Ghia. There was also a Cobra option available (17,579 produced in 1979) that completed the lineup through 1981. Engine choices included the 2.3 L Pinto inline-four, 2.8 L Cologne V6 (made by Ford of Europe), and the . All were carried over from the Mustang II line. Supplies of the 2.8 L proved inadequate leading to it being replaced in late 1979 with Ford's 3.3 L straight-six. A new 2.3 L turbo four-cylinder, debuted that offered similar horsepower to the V8. The automaker's had plans this engine would usher in a new era in performance. The 2.3 and 2.3 Turbo and V8 models could also be optioned with the newly developed TRX handling suspension, which utilized Michelin 390 mm tires and specific metric wheels. The Mustang was again chosen as pace car at the Indianapolis 500. Ford commemorated this with an "Indy 500" pace car edition, of which 10,478 were produced. The two-tone pewter and black colors were complimented with vibrant Orange & Red graphics. Available were the 2.3 L Turbo with mandatory four-speed manual transmission or the V8 with either the manual or three-speed automatic transmission. The three actual Pace Cars were fitted with a T-roof by Cars & Concepts of Brighton, MI. The T-roof option would not become an available option until the 1981 model year.〔 Following the second oil crisis in 1979, the was dropped in favor of a new V8 due to its better fuel economy. It was the only V8 offered in 1980 and 1981. Basically a sleeved down 302, the 4.2 L V8 had restrictive heads and managed to produce , the lowest power ever for a Mustang V8. The 4.2 L was mated only with the three-speed automatic transmission. This meant the 2.3 L Turbo 4 was the sole "performance" engine. The Turbo 4 was plagued with reliability issues from its release. Inadequate lubrication led to premature turbo failure and some engines caught fire. It was listed as an option through 1981, but dropped for 1982, although it was still available in Canada. This engine would return in the new-for-1983 Turbo GT. The "Traction-Lok" limited slip differential was available for the first time in 1981, with all engine combinations. A five-speed manual option arrived late during the 1980 model year, originally only in the 2.3-liter four-cylinder engines. New for 1981 was an optional Traction-Lok rear axle (all engines), and a T-bar roof.〔 In 1982, the returned. The new H.O. (for High Output) engine, available only with the four-speed manual transmission, was modified from the 1979 version. Now producing , the re-engineered 302 consisted of new valves, a more aggressive cam (from a 1973 351W Torino application), a larger twin-barrel carburetor, and a revised firing order, as well as a better breathing intake and exhaust system. The 4.2 L, now in its final year and available only with an automatic, could be substituted in the place of the 302 resulting in a US$57 credit to the buyer. Trim levels were also revised to now included L (base), GL, GLX, and GT. The Cobra option was no longer available. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ford Mustang (third generation)」の詳細全文を読む スポンサード リンク
