Despite recent fuel prices, pickup trucks continue to be popular choices for transportation. They are highly customizable from the factory, they provide a commanding view of the road, they can carry just about anything, and they’re more luxurious than ever before. The GMC Sierra 1500 and its twin (Chevrolet Silverado 1500) received a fresh update back in 2015 that General Motors hopes will sway customers away from the popular Ford F-150.
Performance – Part of that refresh is what’s under the hood of every GMC Sierra 1500. There are 3 engines for customers to choose from; a 4.3L V6, a 5.3L V8 and a 6.2L V8. The truck being tested here is equipped with the 5.3L V8 that will occupy the engine bays of majority of Sierras sold. It produces 355 horsepower and 383 lb-ft of torque. With an empty bed, the engine feels like it barely needs to exert any effort to move the 2,600kg truck. There’s plenty of grunt down low in the rev range with peak power coming just before the redline. However the engine doesn’t have a sense of urgency due to a very slow throttle response. Under light throttle applications, there’s a noticeable delay between the time the throttle is depressed and the engine reacting to the input. Not helping is the automatic transmission. There’s a choice of either a 6-speed (as tested) or an 8-speed, neither of which are very quick when it comes to doing their jobs of shifting gears. Under full throttle applications, the engine and transmission are a bit more immediate in their response but majority of people don’t continuously drive as though they’re on a race track.
