The GMC Jimmy entered the market in 1984 as a Chevrolet Blazer rebadged model from General Motors. During production at Pontiac Michigan and Shreveport Louisiana from 1984 to 2005 the GMC Jimmy entered the market. In 1991 GMC Jimmy received a makeover by adding a wagon version to its existing two-door model specification. The Jimmy featured a front-engine, four-wheel-drive layout, offering solid off-road capability and all-weather traction for varied driving conditions. A succession of engine power options changed from initial 1.9 and 2.0 L gasoline power to 2.5 L Iron Duke power or increased strength which achieved higher output levels. A power upgrade to 160 hp (120 kW) happened during 1989 before GMC Jimmy started using the 4.3 L Vortec 4300 V6 engine to boost performance levels further. Drivers could choose between a 4-speed automatic transmission and a 5-speed NV3500 manual transmission to change their driving experience. The GMC Jimmy's mechanics have received multiple generations of improvements for both performance and quality standards. Genuine GMC Jimmy parts, such as grilles and wheels, are factory-designed to ensure durability, proper fit, and to preserve the vehicle's proven reliability and efficiency.
