Eighth generation (1973–1991)
en.wikipedia.org
The Chevrolet Suburban is a large sport utility vehicle from Chevrolet. It is the longest continuous use automobile nameplate in production, starting from 1934 for the 1935 U.S. model year. The Suburban has been produced under the Chevrolet, Holden, and GMC marques until the GMC version was rebranded as the GMC Yukon XL. For most of its recent history, the Suburban has been a station wagon-bodied version of the Chevrolet pickup truck, including the Chevrolet C/K and Silverado series of truck-based vehicles. Cadillac offers a version called the Escalade ESV. The Suburban has traditionally been one of General Motors' most profitable vehicles although sales have gone down in recent years due to the cost of gasoline and the poor fuel economy of the vehicle.
Eighth generation (1973–1991)
With the third generation Rounded-Line C/K models, the Suburban became a 4-door vehicle.[17] The Rounded-Line 1970s body style remained largely unchanged for 19 model years - making this series the longest Suburban generation in production. Both 2WD and 4WD models, designated "C" and "K", were offered, as well as one-half ton and three-quarter ton models ("10" and "20" on the Chevrolet models, "1500" and "2500" on GMC models). The one-ton model designation was the C or K 30 for GMC and 3500 for Chevrolet.
In 1986 and 1987, the method of fuel delivery for the engines was switched from carburetors to electronic fuel injection. The system that GM chose was called throttle body injection, or TBI. Suburban gained rear-wheel anti-lock braking system (ABS) for the 1990 model year. A heavy-duty four-speed automatic transmission, the 4L80-E was added in 1991.
