[3] The Syclone features a 4.3L turbocharged V6 engine with an automatic transmission and an AWD (all-wheel drive) driveline and 4-wheel anti-lock brakes.

Both the Syclone and Typhoon trucks feature a Mitsubishi TD06-17C 8cm² turbocharger[2] and Garrett water/air intercooler attached to a 4.3L LB4 V6 engine featuring upgrades that included hypereutectic pistons, nodular iron main caps, upgraded head gaskets, intake manifolds, exhaust manifolds, and a 48 mm (1.9 in) twin-bore throttle body from the 5.7L Chevrolet small-block engine.

Out of the 150 trucks, there were an estimated 113 destined for resale in the Middle East and were modified with a metric dash cluster, leaded fuel chip, and a resonator in place of the catalytic converter.

Rather than selling the 31 trucks to the public, GMC set up a lottery where employees could enter their name to be drawn to have the chance at purchasing a Saudi Syclone as a significantly reduced price ($12,500) and had to take delivery through a dealership.

In 2009, a poor-condition GMC Syclone was scrapped under the U.S. federal government Car Allowance Rebate System (colloquially known as "cash for clunkers"), despite being highly collectible.

All ten trucks were provided to American Sunroof Company (ASC), by Shinoda Design Associates, Inc., in conjunction with Phillip Morris, Inc. With the help of Larry Shinoda, designer of the Corvette Stingray and Boss Mustang, a transformation of the originally black Syclones took place.

One of these Indy trucks was later converted into the PPG Syclone Pace Truck (though it was not the official pace car) with significant modifications to be used on the track, including a multi-colored silver, magenta, and aqua paint scheme, and a molded in light bar in the roof, a racing fuel cell, a built-in halon fire suppression system, water-cooled brakes, and color-matched leather interior to the exterior paint scheme.

The bed has a multi-piece tonneau cover that folds with the tailgate in the fashion of an accordion to reveal the fuel cell, batteries, and halon canister mounts.

The PPG Syclone[9] was retired to the GM Heritage Collection where it was stored and occasionally taken out for car shows until it was auctioned at Barrett Jackson in 2009, selling for $66,000.
