Chevrolet Tahoe Horsepower by Year
The Chevrolet Tahoe’s catalog horsepower spans 255 to 420 hp across model years 1999 through 2023. This page covers all catalog years in that range; the figures are a broad summary, not one rating shared by every Tahoe.
Horsepower varies by year and engine, so use the catalog entry for the specific Tahoe year and configuration rather than treating the range endpoints as a rating for a particular vehicle. The listed span shows the lowest and highest figures in the catalog; it does not identify which engine or trim has each figure.
If a horsepower figure for your vehicle is not listed, confirm it in the owner’s manual.
