1991 GMC Syclone ChallengeIn 1991, Vista Group,

1991 GMC Syclone ChallengeIn 1991, Vista Group, in coordination with GMC Truck Division, organized a promotional event called the “Syclone Challenge” to coincide with the launch of the GMC Syclone. The trucks used in the event were referred to as the “Syclone Challenge Trucks.”The Syclone Challenge was part of a traveling roadshow, which was a marketing strategy for GMC dealers to showcase new truck models. This included a selection of show trucks, one of which was the famous 1989/90 Syclone LSR (Land Speed Record) truck. Attendees to the show could see up close the latest in GMC Trucks and take home various GMC Truck Motorsports literature, posters, and apparel. The display traveled the National Hot Rod Association (NHRA) tour and allowed local GMC Truck dealer groups to showcase the new GMC Syclone pickup truck in an optimal high-performance setting – the quarter-mile track.#sytyregistry #gmcsyclone #gmctyphoon #sportmachines #turbotruck
