In 1991, GMC offered a pickup that could out-accelerate a Ferrari 348. The Syclone packed a turbocharged and intercooled 4.3L V6 rated at 280 horsepower and 350 lb-ft of torque. It sent power through a 4-speed automatic to a performance-oriented all-wheel-drive system, resulting in 0-60 mph times under 5 seconds. Production was limited to just 2,995 units for the 1991 model year, all finished in black.
The Syclone's combination of rarity, world-beating performance, and its status as a factory-built muscle truck makes it a 90s icon. It was a bold statement from GMC and one of the first trucks to prioritize on-road speed over utility. For collectors, it represents a unique moment in performance history and a high point for factory sleepers.
Buying Tips
- Check the Kelsey-Hayes ABS for a faulty accumulator, often indicated by a constantly running pump or warning lights.
- Inspect the unique body cladding for fading, cracks, or damage, as replacement parts are scarce and expensive.
- Examine the frame, cab corners, and rocker panels for rust, which can be hidden by the lower body cladding.
- Favor stock or well-documented examples, as many were modified for more power, sometimes with poor results.
- Test the 4-speed 700R4/4L60 transmission for smooth shifts, as it can be a weak point, especially on modified trucks.
