The GMC S15 pickup truck was a compact truck that was manufactured between 1982 and 2004. It was named both the S15 and the Sonoma, and was identical, but for trim and badging, to the Chevrolet S10 pickup truck. In 1991, GMC offered a high-performance version of the S15 pickup and called it the Syclone. The S15 was also badged and sold by Isuzu as the Hombre in the late 1990s. There was even an electric version of the S15 pickup that was used as a fleet truck. Now that it is no longer in production, the GMC S15 pickup has become collectible.
