The Chevrolet Tahoe (and similar GMC Yukon) is a full-size SUV from General Motors. Chevrolet and GMC sold two different-sized SUVs under their Blazer and 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 1995's introduction of a four-door version to rebadge the compact S-10 Blazer as the Blazer, renaming the full-size Blazer as the Tahoe.
The Chevrolet Tahoe and GMC Yukon currently serve as General Motors' full-size SUVs. Lengthened wheelbase models are available for both as the Suburban for the Tahoe and Yukon XL for the Yukon. A luxury Denali model joined the Yukon lineup in 1998. As of 2002, a Denali version of the Yukon XL was also available as the Yukon XL Denali.
In the United States, the Tahoe is a popular alternative to the Ford Crown Victoria for police car use, especially in rural areas.
The vehicles were redesigned for the 2000 model year on the new GMT800 platform, still shared with the full-sized pickups. Two new engines replaced the old 5.7 L small-block, and while both were smaller, both produced more power. The manual transmission was dropped. In Mexico, the GMT800 Chevy Tahoe is called a Chevrolet Sonora.
Both vehicles received significant updates with only the grille and headlights distinguishing one from the other. Both vehicles now featured softer lines as part of a more aerodynamic design. The interior was also updated with new seats, dashboard, and door panels.
"StabiliTrak" stability control was offered for the first time in 2003, as were XM Satellite Radio, Bose audio, and a DVD entertainment system as the models continued to climb upmarket. Both engines received 10 hp (7.5 kW) more for 2004.
