More power, fresh styling, and new features highlight the 2007 redesign of these large SUVs. Tahoe shares its basic design with the GMC Yukon and Denali and Cadillac Escalade. All three also come in extended-length versions; Tahoe's is called the Suburban. All these GM SUVs have more cargo space and rear passenger room than the 2000-2006 generation, despite little-changed exterior dimensions.

Tahoe comes in LS, LT, and luxury LTZ trim. Each offers rear-wheel drive or 4-wheel drive that can be left engaged on dry pavement and includes low-range gearing. ABS and traction/antiskid control with rollover sensors is standard.

A 295-hp 4.8-liter V8 is standard on the 2WD LS. A 320-hp 5.3-liter V8 is optional on that model and standard on all other Tahoes. The 5.3 V8 has GM's Active Fuel Management cylinder deactivation. The only transmission is a 4-speed automatic. Standard on LTZs is GM's Autoride suspension that includes load leveling and automatically adjusts firmness based on road and driving conditions. LT is also available with Chevy's Z71 Off-Road Suspension Package.

Passenger capacity ranges from five to nine, with two- and three-place seating available for any of the three rows. Standard with LTZ and available for LS and LT are curtain side airbags that cover all seating rows and include rollover deployment. The 2nd- and 3rd-row seats fold, and the 3rd row is removable. As in GM's other large SUVs, a spring release option flips the 2nd-row seats to provide 3rd row access. Other new features include a rearview camera, power liftgate, power running boards, and rear obstacle detection. Also available are a navigation system, power-adjustable pedals, heated 1st- and 2nd-row seats, and DVD entertainment. OnStar assistance is standard.
