tarnished reputation that could never be made better, no matter how hard the ad men at Dearborn slaved.
A number of other cars by other manufacturers on the US market were no safer than the Pinto, and also had unprotected fuel tanks behind the axle. Ford was merely unlucky enough to be exposed.

Design of the Pinto Fuel System:
In 1968, Ford began designing a new subcompact automobile which ultimately became the Pinto. Mr. Iacocca, then a Ford vice president, conceived the project and was its moving force. Ford’s objective was to build a car at or below 2,000 pounds to sell for no more than $2,000.
Ordinarily marketing surveys and preliminary engineering studies precede the styling of a new automobile line. Pinto, however, was a rush project, so that styling preceded engineering and dictated engineering design to a greater degree than usual. Among the engineering decisions dictated by styling was the placement of the fuel tank. It was then the preferred practice in Europe and Japan to locate the gas tank over the rear axle in subcompacts because a small vehicle has less “crush space” between the rear axle and the bumper than larger cars. The Pinto’s styling, however, required the tank to be placed behind the rear axle leaving only 9 or 10 inches of “crush space”— far less than in any other American automobile or Ford overseas subcompact. In addition, the Pinto was designed so that its bumper was little more than a chrome strip, less substantial than the bumper of any other American car produced then or later. The Pinto’s rear structure also lacked reinforcing members known as “hat sections” (two longitudinal side members) and horizontal cross-members running between them such as were found in cars of larger unitized construction and in all automobiles produced by Ford’s overseas operations. The absence of the reinforcing members rendered the Pinto less crush resistant than other vehicles. Finally, the differential housing selected for the Pinto had an exposed flange and a line of exposed bolt heads. These protrusions were sufficient to puncture a gas tank driven forward against the differential upon rear impact.
Crash Tests:
During the development of the Pinto, prototypes were built and tested. Some were “mechanical prototypes” which duplicated mechanical features of the design but not its appearance while others, referred to as “engineering prototypes,” were true duplicates of the design car. These prototypes as well as two production Pintos were crash tested by Ford to determine, among other things, the integrity of the fuel system in rear-end accidents. Ford also conducted the tests to see if the Pinto as designed would meet a proposed federal regulation requiring all automobiles manufactured in 1972 to be able to withstand a 20-mile-per-hour fixed barrier impact without significant fuel spillage and all automobiles manufactured after January 1, 1973, to withstand a 30-mile-per-hour fixed barrier impact without significant fuel spillage.
The crash tests revealed that the Pinto’s fuel system as designed could not meet the 20-mile-per-hour proposed standard. Mechanical prototypes struck from the rear with a moving barrier at 21 miles per hour caused the fuel tank to be driven forward and to be punctured, causing fuel leakage in excess of the standard prescribed by the proposed regulation. A production Pinto crash tested at 21 miles per hour into a fixed barrier caused the fuel neck to be torn from the gas tank and the tank to be punctured by a bolt head on the differential housing. In at least one test, spilled fuel entered the driver’s compartment through gaps resulting from the separation of the seams joining the rear wheel wells to the floor pan. The seam separation was occasioned by the lack of reinforcement in the rear structure and insufficient welds of the wheel wells to the floor pan.
Tests conducted by Ford on other vehicles, including modified or reinforced mechanical Pinto prototypes, proved safe at speeds at which the Pinto failed. Where rubber bladders had been installed in the tank, crash tests into fixed barriers at 21 miles per hour withstood leakage from punctures in the gas tank. Vehicles with fuel tanks installed above rather than behind the rear axle passed the fuel system integrity test at 31-miles-per-hour fixed barrier. A Pinto with two longitudinal hat sections added to firm up the rear structure passed a 20-mile-per-hour rear impact fixed barrier test with no fuel leakage.
The Cost to Remedy Design Deficiencies:
When a prototype failed the fuel system integrity test, the standard of care for engineers in the industry was to redesign and retest it. The vulnerability of the production Pinto’s fuel tank at speeds of 20 and 30-miles-per-hour fixed barrier tests could have been remedied by inexpensive “fixes,” but Ford produced and sold the Pinto to the public without doing anything to remedy the defects. Design changes that would have enhanced the integrity of the fuel tank system at relatively little cost per car included the following: Longitudinal side members and cross members at $2.40 and $1.80, respectively; a single shock absorbent “flak suit” to protect the tank at $4; a tank within a tank and placement of the tank over the axle at $5.08 to $5.79; a nylon bladder within the tank at $5.25 to $8; placement of the tank over the axle surrounded with a protective barrier at a cost of $9.95 per car; substitution of a rear axle with a smooth differential housing at a cost of $2.10; imposition of a protective shield between the differential housing and the tank at $2.35; improvement and reinforcement of the bumper at $2.60; addition of eight inches of crush space a cost of $6.40. Equipping the car with a reinforced rear structure, smooth axle, improved bumper and additional crush space at a total cost of $15.30 would have made the fuel tank safe in a 34 to 38-mile- per-hour rear-end collision by a vehicle the size of the Ford Galaxie. If, in addition to the foregoing, a bladder or tank within a tank were used or if the tank were protected with a shield, it would have been safe in a 40 to 45-mile-per- hour rear impact. If the tank had been located over the rear axle, it would have been safe in a rear impact at 50 miles per hour or more.
Management’s Decision to Go Forward With Knowledge of Defects:
The idea for the Pinto, as has been noted, was conceived by Mr. Iacocca, then executive vice president of Ford. The feasibility study was conducted under the supervision of Mr. Robert Alexander, vice president of car engineering. Ford’s Product Planning Committee, whose members included Mr. Iacocca, Mr. Robert Alexander, and Mr. Harold MacDonald, Ford’s group vice president of car engineering, approved the Pinto’s concept and made the decision to go forward with the project. During the course of the project, regular product review meetings were held which were chaired by Mr. MacDonald and attended by Mr. Alexander. As the project approached actual production, the engineers responsible for the components of the project “signed off ” to their immediate supervisors who in turn “signed off ” to their superiors and so on up the chain of command until the entire project was approved for public release by Vice Presidents Alexander and MacDonald and ultimately by Mr. Iacocca. The Pinto crash tests results had been forwarded up the chain of command to the ultimate decision-makers and were known to the Ford officials who decided to go forward with production.
Harley Copp, a former Ford engineer and executive in charge of the crash testing program, testified that the highest level of Ford’s management made the decision to go forward with the production of the Pinto, knowing that the gas tank was vulnerable to puncture and rupture at low rear impact speeds creating a significant risk of death or injury from fire and knowing that “fixes” were feasible at nominal cost. He testified that management’s decision was based on the cost savings which would inure from omitting or delaying the “fixes.”
Mr. Copp’s testimony concerning management’s awareness of the crash tests results and the vulnerability of the Pinto fuel system was corroborated by other evidence. At an April 1971 product review meeting chaired by Mr.
