GMC Sonoma

The GMC Sonoma and the very similar Chevrolet S-10 were compact pickup trucks from the GMC marquee of General Motors. At its introduction in 1982, the GMC version was known as the S-15, and the high-performance version was known as the GMC Syclone. Additionally, the truck was sold by Isuzu as the Hombre from 1996 through 2000. Later a Sport Utility Version was spawned under the name GMC S-15 Jimmy. An electric version was also released as a fleet vehicle in 1997 and in 1998, although it seems that the technology was not advanced enough at the time to draw return buyers. The GMC S-15 became the GMC Sonoma in 1991, and the Sierra trim packages were dropped to avoid confusion with the new GMC Sierra full-size pickup. The GMC Syclone also made its appearance that year. A limited edition model was released and sold in 1992 as the Sonoma GT. It used a 4.3 L L35 V6, which produced 195 hp (145 kW). The appearance was similar to the 1991 GMC Syclone "super-truck" but not enough to attract many consumers. In 1992, there were only 806 Sonoma GT's produced. Another interesting thing occurred in 1993 for an unknown number of units. Some 1993 GMC Sonomas came with a factory equipped L35 W code engine. For 1993 no specialty labeling or limited edition tags were known to be issued with the W coded engine so it seems that drivers may have a limited edition model and not even know it. The difference between the engines is that the W code used a balance shaft, roller camshaft, different heads and Central Port Injection. The 1992 and 1993 engine came in either a 195 or 205 hp rating. The High Performance version came with a larger diameter Y pipe, and was only installed in some of the Blazers and S-10 Jimmys.
