Think of this truck as a professional grade tool for work, with the durability and versatility we’ve all come to expect from the GMC nameplate. GM says the Sierra is tops in many categories, including gross vehicle weight and maximum towing capacity, which checks in at 16,700 pounds. And with extensive noise-reduction measures, it has one of the quietest interiors among heavy-duty trucks. Add in the luxurious Denali trim package, and this pickup is tops in all regards. It’s what’s under the hood that separates the men from the boys among heavy-duty pickups. Most folks will get by just fine with this standard 6.0L gas V8 engine that uses variable valve timing to produce 353-horsepower and 373 ft-lbs of torque. Both the interior and exterior are designed to make this HD version look different from its milder cousins. Differences include larger door-pull handles, plus a new grille, hood and front fenders. Rear seating in our crew cab means there is roomy comfort for three people back there, with 38.7 inches of rear legroom to boot. The rear seat is split 60/40 and can folded up individually for a flat load floor. Silverado may be the more popular of the two GM models, but truck buyers shouldn’t overlook this Sierra just because there aren’t as many of them. For a truck, it offers a refined driving experience and an upscale cabin that wouldn’t be out of place in a premium SUV. This is a truck with class-leading power efficiency and smarts.
