The original Chevrolet Suburban Carryall debuted as a 1935 model. Based on a Chevy pickup truck chassis, it wore a two-door steel wagon body, could seat eight, and had a 60-horsepower, six-cylinder engine. It cost $675. Over the years, the Suburban has evolved dramatically while remaining remarkably close to its truck-based wagon origins. Features we take for granted today, like an automatic transmission, didn’t join the options list until 1955, while factory air conditioning was first offered in 1965. In 1967, Chevy introduced an unusual three-door design with a single driver-side door and front and rear doors on the passenger side. The 1973 model was the first to have four doors. The Suburban was redesigned again for 1992, 2000, 2007, 2015 and 2021. The current Suburban is the 13th generation of Chevy’s full-size SUV.
