NEW FOR 2011: - 20-inch chrome-clad wheels available on LTZ - Trailering package includes integrated trailer brake controller - Exterior colours: Mocha Steel Metallic, Steel Green Metallic and Ice Blue Metallic added For 2011, changes to the Chevrolet Tahoe are minor. There are 20-inch chrome-clad wheels available for the LTZ trim line, and the trailer package now includes an integrated trailer brake controller. The Tahoe uses a 5.3-litre V8 engine with six-speed automatic transmission, while the Tahoe Hybrid uses a 6.0-litre V8 and hybrid electric propulsion unit with four-speed automatic transmission. All engines use Active Fuel Management, which shuts off half the cylinders under light load for improved fuel economy. The Hybrid can launch and travel at speeds of up to 49 km/h on its battery alone, and features an automatic-stop that shuts off the gasoline engine when the truck is stopped, such as at a light. The battery pack is recharged through regenerative braking. The LS and LT come standard with two rows of seats, but can be optioned with a third row; the LTZ and Hybrid come only with three rows.
