GMC Truck has a longstanding history in IndyCar as the official support truck for the race series. In 1991, three Syclones were converted into Indy Pace trucks by applying Indianapolis 500 graphic decals on the fenders, doors, and bed of the trucks. These trucks were known as the 1991 GMC Indy Syclones. Later on, one of these three trucks was converted again and became the PPG Syclone.
Syclone #2267 – Last known information was this truck was totaled in Georgia in 2008.
Syclone #2268 – Converted into the PPG Syclone and kept with GM until 2009 where it was auctioned at Barrett Jackson. The PPG Syclone was sold and shipped to Reno, NV into a private collection. It was then resold again to another private collection. The last known location was in Colorado.
