2005 GMC Sierra Truck Driving Impressions
On the road, the Sierra is quiet and well behaved, more so than other full-size pickups. It's stable at high speeds, particularly the longer wheelbase (143.5-inch) models. It rides well and handles well. The optional 5.3-liter V8 (327 cubic inches) delivers pleasurable performance around town and on the Interstate. Called the Vortec 5300 by GM, it's rated 295 horsepower and 335 pound-feet of torque, plenty for light towing and hauling. For 2005, an aluminum-block version of this engine produces 310 horsepower, but is available in Extended Cab, standard-box 4WD models only. The base V6 produces 195 horsepower and 260 pound-feet of torque, but most Sierra buyers opt for a V8 and automatic transmission. With 285 horsepower and 295 pound-feet, the 4.8-liter Vortec 4800 V8 is the most popular engine for this truck. With its 6.0-liter, 345-horsepower V8, the Denali really gets with the program.
