A 1972 safety commission report conducted by Texas A&M University concluded that the 1960–1963 Corvair possessed no greater potential for loss of control than its contemporary competitors in extreme situations. The U.S. Department of Transportation (DOT) issued a press release in 1972 describing the findings of NHTSA testing from the previous year. NHTSA had conducted a series of comparative tests in 1971 studying the handling of the 1963 Corvair and four contemporary cars—a Ford Falcon, Plymouth Valiant, Volkswagen Beetle, and Renault Dauphine—along with a second-generation Corvair (with its completely redesigned, independent rear suspension). The 143-page report reviewed NHTSA's extreme-condition handling tests, national crash-involvement data for the cars in the test as well as General Motors' internal documentation regarding the Corvair's handling. NHTSA went on to contract an independent advisory panel of engineers to review the tests. This review panel concluded that "the 1960–63 Corvair compares favorably with contemporary vehicles used in the tests [...] the handling and stability performance of the 1960–63 Corvair does not result in an abnormal potential for loss of control or rollover, and it is at least as good as the performance of some contemporary vehicles both foreign and domestic." Former GM executive and automotive engineer John DeLorean asserted in his book "On a Clear Day You Can See General Motors" that Nader's criticisms were valid.
