Model Year Highlights
  • All 1991 models came with restyled front and rear bumpers featuring wrap around parking lamps and convex shaped brake lights.
  • Base wheels were the same size as the 1990 model but featured a new saw-blade design.
  • Callaway twin-turbo production ended in 1991. The 500th Callaway Twin Turbo model was built on 9-26-91.
  • RPO Z07 was a new option for '91 and combined the previous Z51 performance handling option with the FX3 selective ride and handling option. This new option used all heavy duty suspension parts yielding a ride that ranged from firm to very firm. This option was limited to coupes only.
  • Mufflers were redesigned from 1991 featuring larger sized, better exhaust sound control and lower back pressure.
  • New for 1991 was:  power delay feature which allowed the stereo system and power windows to continue to operate after the igntion was turned to "lock" or "off", power wire for 12 volt devices, a sensor using an oil pan float to monitor oil level, AM band on the radios was expanded to receive more frequencies.
