GMC, with the help of Production Automotive Services, built the Syclone as a performance version of its Sonoma truck. Production started in 1991 and came to an abrupt halt in 1992 with only 2,998 made.
See the video below for a walk around tour of this GMC Syclone:
This first-year example is finished in monochromatic black accented with red GMC badging and graphics. The front end wears amber turn signals integrated into the bumper with fog lights placed in the lower front fascia.
The interior houses black cloth bucket seats outlined in red piping and with “Syclone” embroidered in red on the headrests.
Power comes from a turbocharged and intercooled 4.3-liter V8 paired with a 4-speed automatic transmission and a “transfer case which sends 35 percent of available power to the front wheels and 65 percent to the rear,” the auction house says in the truck’s listing.
This Syclone’s auction ends August 16 at 12:20 p.m. PDT.
