1991 GMC Syclone

The GMC Syclone is a high-performance version of the GMC Sonoma pickup. Produced in 1991 by GMC along with PAS - the same company credited with building the famed 1989 Turbo Trans Am. The Sylcone spawned the similarly powered 1992-1993 GMC Typhoon based on the Jimmy platform. The Syclone was only available in black. For the upcoming 1992 production, a wider range of colors was to be offered however the Syclone was canceled before full production could begin. In total 2,998 Syclones were built. Out of that number only 3 were built in 1992. The #0001 truck was used for DOT crash testing while the other 2 are privately owned.

The exterior registers as sinister. Add gallons of black paint and some snazzy stickers-badges and voila! We have a winner folks. A limited production AWD truck that is all stock with the exception of an aftermarket boost gauge and always regularly maintained with service records available. These trucks are rare to begin with and it's even rarer to find one that hasn't been molested, we proudly give you the one and only GMC Syclone to grace the hallowed halls of the Classic Auto Mall.

Exterior
Purchased by our consignor in August 1999, lovingly cared for along the way and appearing at first glance to be a mild-mannered run of the mill GMC Sonoma this truck has a few tricks up its sleeve. Black paint, blackened trimmings, tinted windows and a fire red set of badges are the only deviations seen here from the all black theme. Straight steel well minded gaps, nice paint, and a black vinyl bed cover keep this truck looking like it is speeding along even when standing still. A peek under the bed cover shows a cargo area that hasn't seen much cargo, no dents seen here, just some light scuffs and scratches on the inside of the tailgate. Machined and natural finish aluminum wheels fill the wheel openings and are wrapped in 245/50R16 Goodyear Firehawk rubber.

Interior
With a swing of the door, we are greeted with a blend of colors and materials. The door panels include just about every facet of interior engineering. We see black cloth, charcoal carpeting, charcoal vinyl, and gray plastic. All of this holds the armrest, power window switch, and power lock switch. Bucket seats in black velour have a very wide tuck and roll insert pattern with long smooth bolsters. Red piping breaks up the sea of black and Syclone is stitched into the headrests in the same red material. These buckets flank a center console that holds an oversized storage compartment along with the gear selector and a pair of cupholders. A leather wrapped ergonomic steering wheel fronts a rectangular panel that holds the gauge layout. Headlight and HVAC controls flank this cluster and to the right is the factory AM/FM/Cassette player. The only deviation from factory stock is an Autometer Sport Comp boost gauge mounted on the A-pillar. Black carpet floods the floors and shows slight fading. A tight black headliner hangs above.

Drivetrain
Crammed into the engine bay is a 4.3L turbocharged V6. This engine is fed by EFI and not only has a turbo but also an intercooler. All is complete under the hood while showing some patina on the litany of hoses, wiring, and ducting. A 4L60E 4-speed automatic, swiped from the Corvette, is on the back. This transmission feeds power through a Borg Warner 4472 transfer case and then to the front and rear axles which weigh in at a 3.42 ratio with limited slip.

Undercarriage
Just a slight bit of surface rust on the frame structure but otherwise clean and rust-free structure and underside. Power disc brakes are on front, and power drums for the rear. A stock style muffler system hangs underneath. Independent coil spring suspension is up front and leaf springs are on the rear all to provide a comfortable sure footed ride.

Drivability
I slipped into the plush and comfy driver's seat and off to the test track I went. I was met with neck snapping acceleration, especially once the turbo kicked in, great handling, bias free braking, and nary a hint of tire spin thanks to the AWD platform. The automatic transmission shifted firmly, and all functions were working as they should. We do note that the anti-lock brake light is on.

Join the ranks of the limited Syclone owners as with only under 3,000 built they don't come up for sale very often. All black, all beautiful, and ready to surprise some unsuspecting Corvettes, Camaros, and Mustangs. Come visit the Classic Auto Mall and get ready to haul some cargo and some ass!
