Ford Mustang
Engines for the 1974 models included the venerable 2.3 L I-4 from the Pinto and the 2.8 L Cologne V6 from the Mercury Capri. The 1975 model year reintroduced Windsor V8 that was only available with the C-4 automatic transmission, power brakes, and power steering. This continued through production end in 1978. Other transmissions were the RAD 4-speed with unique gearing for all three engines, and the C-3 automatic behind the 2.3 L and 2.8 L. The 5.0 L designation was not applied until the 1978 King Cobra model. All 302 equipped Mustang II's, except the King Cobra received an updated version of the classic Ford "V8" emblem on each front fender.
Ford Pinto
The Pinto's design positioned its fuel tank between the rear axle and the rear bumper, a standard practice in US subcompact cars at the time. The Pinto's vulnerability to fuel leakage and fire in a rear-end collision was exacerbated by reduced rear "crush space", a lack of structural reinforcement in the rear, and an "essentially ornamental" rear bumper (though similar to other manufacturers). Crash testing, conducted in 1970 with modified Ford Mavericks, as part of a response to NHTSA proposed regulations, demonstrated vulnerability at fairly low crash speeds. Design changes were made, but post launch tests showed similar results. These tests were conducted to develop crash testing standards rather than specifically investigating fuel system integrity. Though Ford engineers were not pleased with the car's performance, no reports of the time indicate particular concern.
Ford also tested several different vehicle modifications which could improve rear impact performance. However, the engineer's occupational caution and aversion to "unproven" solutions as well as a view that the crash test results were inconclusive resulted in the use of a conventional fuel tank design and placement. The use of an above the axle tank location was considered safer by some (but not all) at Ford. This placement was not a viable option for the hatchback and station wagon body styles.
