CIPA Optic LED Mirrors The Chevrolet Tahoe (and very similar GMC Yukon) are full-size SUVs 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 1992. Chevrolet waited until 1994's introduction of a four-door version to rebadge the mid-size S-10 Blazer as the Blazer, renaming the full-size Blazer as the Tahoe.
