Modified by Production Automotive Services of Troy, Michigan, the Sonoma GT featured a unique “Syclone inspired” cladding kit. While sharing the same front and rear bumper as the Syclone (and future 92-93 GMC Typhoon), the aero package did not have as much of an aggressive look as the Syclone but still featured bumperettes, lower door skirts, and rear quarter bed corners to round out the cladding package. GMC also decided to follow through with the Syclone theme into the interior which featured the same black and red piping door inserts and bucket seats – sans any headrest logo (the Syclone featured embroidered headrest logos), along with the same center console and shifter as seen in the Syclone. The gauge cluster was also the same setup, however due to the non turbo-charged powerplant of the Sonoma GT, the boost gauge is not included in the RPM cluster. The Sonoma GT's production only lasted for 1992.
