The 2009 Chevrolet Tahoe is available in LS, LT, LTZ and Hybrid models, in either 2WD or 4WD. All Tahoe models are built on GM's full-size SUV platform that incorporates features such as a fully boxed frame, coil-over-shock front suspension, and rack-and-pinion steering. StabiliTrak stability control, ABS, traction control, and curtain airbags for all rows are standard on every trim level.

The big news for 2009 is the new Hydra-Matic 6L80 six-speed transmission that comes standard on all Tahoe models with the Vortec 5.3-liter V-8 and 6.2-liter V-8. By reducing engine rpm at cruising speeds, the new transmission reduces fuel use as well as helping to quiet the SUV's interior. The new Vortec 6.2-liter engine produces 395 horsepower and 417 lb-ft of torque, and is available on LTZ models. The engine features a lightweight aluminum block and variable valve timing.
