Chevy Tahoe generations, 1995 to today
By CarWhere Research · Updated
The Chevrolet Tahoe has had five generations since it replaced the full-size Blazer for 1995: GMT400 (1995–2000), GMT800 (2000–2006), GMT900 (2007–2014), K2XX (2015–2020) and the current T1XX from 2021, which added independent rear suspension and a diesel. It is the shorter sibling of the Suburban and GMC Yukon.
Chevy Tahoe history
The Tahoe began as a rename. GM's GMT400 full-size Blazer, which had dropped the K5 prefix in 1992, became the Chevrolet Tahoe for 1995, sold in three-door and five-door forms; the five-door rode a shorter wheelbase than the Suburban, which was about 12 inches longer in wheelbase and 20 inches longer overall. The three-door Tahoe ended in May 1999.
The GMT800 generation for 2000 standardized the Vortec 4.8L and 5.3L V8s. The GMT900 of 2007 added cylinder deactivation, a 6.2L V8 and, from 2008 to 2013, a two-mode hybrid with a 6.0L V8. The K2XX of 2015 brought EcoTec3 engines and later the RST and a 10-speed automatic.
The current T1XX Tahoe, revealed in Detroit on December 10, 2019, switched to independent rear suspension, which lowered the floor and expanded third-row space, and made a 10-speed automatic standard. It offers 5.3L and 6.2L V8s and, for the first time, a 3.0L Duramax inline-six diesel rated 277 hp and 460 lb-ft at launch.[1],[2],[3],[4],[5]

What to check before you buy one
- Confirm the engine and drivetrain: 5.3L V8, 6.2L V8 or 3.0L Duramax on current trucks, and 2WD or 4WD — badges and trim names do not always tell you.
- On V8s with cylinder deactivation, ask for oil-change records and listen for lifter tick on a cold start.
- Test every row of seats, the power-folding third row and liftgate, and the infotainment and camera systems, which are expensive to repair.
- Check towing history: hitch wear, transmission fluid condition and whether the factory trailering package is fitted.
- Run the VIN through NHTSA's recall lookup (nhtsa.gov/recalls) and have a Chevrolet dealer confirm open campaigns are complete.
- Use the factory build record to confirm packages such as Z71, Max Trailering and Premium options.

Medians of asking prices, not transaction prices; every trim is blended, so performance variants usually sit well above these medians. "Below new median" compares each model year's median used listing with the median listing price of a new 2026 Tahoe today. More in our Chevrolet Tahoe depreciation study.

How to verify a Chevy Tahoe's factory options
Tahoe trims overlap heavily, so the build record is the clearest way to see how a specific VIN was ordered: engine, 2WD or 4WD, axle ratio, Z71 or Max Trailering packages, seating and option groups, when licensed build data exists. It lists ordered-option RPO codes rather than every code on the glovebox label.
