n. Pickup]-style truck produced in 1991. The fastest production truck (along with the GMC Typhoon) ever made. It is a 4.3 liter, turbo-charged, kick ass machine. It's 0-60 in 5.3 seconds (stock) time rivals even the Corvette for the same time period. People who own Syclones are fanatics about them, travelling around the world for the International SY/TY meeting held in Kansas City every year over the Labor Day weekend.
