The GMC Syclone, when introduced, was the fastest stock pickup truck in the world. It was also the first production truck to receive 4-wheel anti-lock brakes.
The Syclone was a high-performance version of the GMC Sonoma Pickup truck. They featured a turbocharged 6-cylinder displacing 4.3-liters and offering 280 horsepower. They had a 700R4 4-speed automatic transmission and Borg Warner all-wheel drive transfer case splitting torque with 35-percent forward and 65-percent to the rear wheels.
The GMC Syclone could accelerate from 0-60 mph in just 4.6 seconds could run the quarter-mile run in 13.4 seconds.
