Here we look at a pair of one-year-only 1991 GMC Syclones. Based on the 4.3L V6 GMC Sonoma pickup, GM added a turbocharger, intercooler, and all-wheel drive system from the Chevy Astro van. This combination made for 0-60 MPH runs in the low four-second range and was far and away the fastest production pickup when it was released. In this video, AMCM's Owner, Mark Pieloch, covers our two Syclones along with some history on the model. | American Muscle Car Museum
