Late in 1991, it was decided by General Motors that an all-new generation of Corvette would have to be put on hold until as late as 1998. While the next generation of Corvette was originally anticipated to arrive in 1995, poor sales prevented General Motors from expending the budgets necessary to develop a new model. Despite this economic downturn, GM did unveil a new concept car in January, 1992.
Note: For Callaway Twin-Turbo, Chevrolet engine coding was replaced as follows: First two digits for year, next three digits for Callaway sequence, last four digits to match the last four digits of the vehicle identification number.
