The '91 GMC Syclone is a high performance pickup derived from the regular GMC Sonoma pickup produced for 1991. The high performance turbocharged engine with all-wheel drive made it the fastest high performance pickup ever made at the time. This sent a shock wave in the car community as its acceleration was comparable to most sports cars at the time.
The Syclone featured all-wheel drive, 4-wheel anti-lock brakes and a turbocharged V-6 engine which, at the time, made it the fastest stock pickup truck in the world.
