[1] Like the GMC Syclone, the Typhoon is powered by a 4.3 L LB4 V6 engine with unique pistons, main caps, head gaskets, intake manifolds, fuel system and exhaust manifolds, producing 280 hp (209 kW) and 360 lb⋅ft (475 N⋅m) of torque.

[2] The engine uses a Mitsubishi TD06-17C/8 cm2 turbocharger producing 14 psi (0.97 bar) of boost and a Garrett Water/Air intercooler, as well as revised intake manifolds, fuel system, exhaust manifolds, and a 48 mm (2 in) twin-bore throttle body from the 5.7 L GM Small-Block engine.

Other features include upgraded brakes, a limited-slip rear differential and sport modifications to the standard suspensions.

Car and Driver compared the Syclone's performance favorably to the Ferrari 348ts, Chevrolet Corvette, and Nissan 300ZX Turbo.

All three model years were built for GMC by Production Automotive Services of Troy, Michigan.
