Ford Pinto
Upon release the Pinto was received with both positive and negative reviews. "Road & Track" faulted the suspension and standard drum brakes, calling the latter a "serious deficiency," but praised the proven 1.6 L "Kent" engine, adapted from European Fords. The larger "2300 inline-4" found in the Chevrolet Vega was an innovative, brand new design using an aluminum alloy block and iron head, but needed more development work as initially released. "Super Stock Magazine" found the fit and finish to be "superior" and were impressed with the car overall. "Car and Driver" found the Pinto, when equipped with the larger 2.0L engine and front disc brakes, to be a nimble and powerful commuter car with good visibility and sports-car feel. A review of the 1974 Pinto with an automatic transmission by "Car and Driver" was not as favorable noting significant decreases in mileage and acceleration.
Ford Pinto
The design of the Pinto fuel system was complicated by the uncertain regulatory environment during the development period. The first federal standard for automotive fuel system safety, passed in 1967, known as Section 301 in the Federal Motor Vehicle Safety Standards, initially only considered front impacts. In January 1969, 18 months into the Pinto's development cycle, the NHTSA proposed expanding the standard to cover rear-end collisions. The proposed standard was based on a 20 mph moving-barrier rear impact test. Ford publicly announced it supported the standard. In August 1970, the month the Pinto went into production, the NHTSA changed the proposal to a more stringent 20 mph fixed-barrier standard which car companies were to meet in 18 months. The fixed-barrier standard was seen by the auto industry as a significant increase in test severity. At the same time the NHTSA announced a long-term goal of setting a 30-mph fixed-barrier standard. Due to the confusion related to the various proposed standards and an expectation that the NHTSA would not select the more stringent 30 mph fixed-barrier standard, Ford elected to voluntarily meet the 20 mph moving-barrier standard for all cars by 1973. Ford and other automobile manufacturers objected to the more stringent fuel system safety standard and filed objections during the required comment periods of the proposed regulations.
