Acceleration and Power
When referring to the Sierra 1500's power, reviewers unanimously agree that the Sierra is a success. All this praise can be accredited to the GMC Sierra 1500's wide variety of engines, all of which were found to provide sufficient power. The base-engine is a 4.3-liter V6, which makes 195 horsepower and 260 pound feet of torque. The next engine level is a 4.8 liter V8, which generates 295 horsepower and 305 pound-feet of torque. Also available is a 5.3- liter V8 that produces 315 horsepower and 338 pound-feet of torque. At the top end of the Sierra's engine options is the 6.2-liter V8 (only available on the crew or extended cab), which makes 403 horsepower and 417 pound-feet of torque.
- "Acceleration is more than adequate at all speeds." -- Consumer Guide
- "Acceleration is sluggish with the base V6 but just fine with even the modest 4.8-liter V8. The 5.3-liter V8 feels brawny, and the 6.2-liter V8 turns the Sierra into a veritable muscle truck." -- Edmunds
- "Acceleration is good, meaning that the GMC Sierra 1500 has no problems entering freeways or changing lanes." -- Washington Post
- "The 4.3-liter V6 and 4.8-liter V8 should be more than adequate in work truck applications." -- Kelley Blue Book
Handling and Braking
Test drivers seem generally pleased with the 2010 GMC Sierra 1500's handling abilities. The majority of reviewers have found that the vehicle handles like a truck, but is not as stiff as previous generations. Different suspension options are available, and each is tuned for different performance strengths. A Z71 off-road suspension is geared for off-roading.
- "Riding on a fully-boxed frame for more chassis stiffness, with coil-over-shock front suspension and rack-and-pinion steering, the big pickup truck is surprisingly nimble and easy to maneuver." -- Kelley Blue Book
- "The new rack and pinion steering enhanced our confidence on the back roads where handling was better than we would expect from such a heavy truck." -- MarketWatch
- "With an unladen cargo bed the Sierra's ride quality is fairly stiff, but the suspension does a good job soaking up large imperfections in the road. Reasonably precise steering response gives the driver much appreciated confidence when driving at highway speeds." -- Cars.com
- "One of the trucks we drove had its bed loaded with heavy cargo and the brakes were good enough that nothing dramatic happened when we had to make a hard and fast stop." -- New Car Test Drive
