The 2006 Chevrolet Tahoe adds a new engine option this year: a Vortec 5300 Flex-Fuel V-8 that can operate on a combination of gasoline and E85 ethanol fuel. Other changes include relocating the catalytic converters closer to the engine for improved emissions, making the tire pressure monitoring system standard, combining the OnStar and XM Satellite Radio antennas into one, and installing a new parking brake adjuster.

The 2006 model year will be the last year that the best-selling Tahoe as we know it exists. (The 2007 model, which went on sale in the second quarter of 2006, is a much different vehicle.) Capable of hauling up to nine passengers when equipped with the optional third row, and able to tow up to 7,800 pounds, the Tahoe has attracted a loyal following. When the second-row seats are folded forward, it creates nearly 105 cubic feet of cargo space and the convenience of a flat floor.

A less lengthy version of the full-size Suburban, the Tahoe offers three-row seating and good cargo-carrying ability in a smaller size than its big brother. Though built on a body-on-frame platform and powered by a gas-thirsty V8, the Tahoe remains a popular choice for families who need room for the kids and power to tow. Rising gas prices have cut into sales, forcing Chevrolet to offer some sweet deals that shave thousands off the Tahoe's MSRP. A significantly revised and restyled version of the Tahoe is expected to arrive soon, so the 2006 is predicted to be the last of the current bodystyle.
