the prosecution's expert, however, made no effort here to compare the Pinto's performance with that of other subcompact cars; this is a comparison which, in light go the hight fatality rate generally associated with subcompact , should play a key role in any evaluation of the Pinto's rear-end integrity. Ford itself, in preparing its criminal defense, did gather comparative data. One Ford memorandum, derived from FARS data, look at 1973 car during the 1975-78 period. The memorandum indicated that the rear-fire fatality number for all subcompacts were rather low. It further showed, however, that the Pinto's rear-fire fatality rate, while considerably below the Gremlin's, was considerably above the respective rates of the Vega , Toyota, Mazda, and Datsun. While this memorandum hardly supported any claim that the Pinto was a major highway hazard. it did suggest that the Pinto's record in this particular class of accidents was worse than the relevant industry average; perhaps for this reason, Ford did not introduce the memorandum during the criminal trial
