First Look: 2009 Chevrolet Avalanche
It's been five years since we've revisited the Chevrolet Avalanche, our 2002 Motor Trend Truck of the Year. Since that time, Chevrolet has addressed the few problems we found with the winner and subsequent one-year test vehicle, including adding more power, ditching the unnecessary plastic body cladding, and upgrading its options. For 2009, the Avalanche adds a host of technological improvements to its already versatile package.
The biggest change to the 2009 Chevrolet Avalanche is the addition of a new Hyrda Matic 6L80 six-speed automatic transmission, which replaces the long-running 4L60 four-speed unit found in earlier Avalanches, improving highway mileage and reducing engine noise in the process. Under the hood, 2WD models come standard with an iron-block 5.3L OHV V-8 that produces 320 hp and 340 lb-ft of torque. 4WD models will first come standard with an aluminum-block, 5.3L OHV V-8 making 310 hp and 335 lb-ft, and then switch over to an iron-block 5.3L making 320 hp and 340 lb-ft featuring Active Fuel Management, which shuts off half the cylinders under light loads, and Flex Fuel capability, allowing it to run on E85 Ethanol. Both the 2WD and 4WD models can be equipped with an optional 6.0L OHV V-8 that features Active Fuel Management as well as Variable Valve Timing producing 366 hp and 376 lb-ft of torque.
