An evolution of the Chevrolet K5 Blazer, the Chevrolet Tahoe is a full-size SUV from General Motors. Chevrolet and GMC sold two different-sized SUVs under their Blazer/Jimmy model names through the early 1990s. This situation changed when GMC rebadged the full-size Jimmy as the Yukon in 1991. Chevrolet waited until the 1995 model year to rebadge the redesigned mid-size S-10 Blazer as the Blazer, renaming the full-size Blazer as the Tahoe. Five generations of the Tahoe have been built: 1st Gen (1995-2000), 2nd Gen (2000-2006), 3rd Gen (2007-2014), 4th Gen (2015-2020), and 5th Gen (2021-).
