GMC Sierra 1500

Current Model
The Sierra is essentially a Chevrolet Silverado. Power delivery is smooth and responsive, and fuel economy is 17 mpg overall for the 5.3-liter V8 engine crew-cab four-wheel-drive version.
A new 3.0-liter turbodiesel six-cylinder engine got an impressive 23 mpg overall. The ride is steady, and the cabin is very quiet. Handling is sound and secure. The infotainment system is easy to use. Rear-seat room in crew-cab versions is immense, but the high step-in requires a climb. Helpful options include a power liftgate that can be opened using the key fob, a tailgate that can be configured into a workbench, and power running boards that can shift back to help reach the bed. The luxurious Denali version has a 6.2-liter V8 mated to a 10-speed automatic. Blind spot warning and automatic emergency braking are optional.

2014-2018
2014 Redesign Year
Sierra's 2014 redesign brought a more spacious cabin that is nearly as quiet as a luxury car's. The truck's relatively low ride height eases access, while the dashboard controls are simple to use.
The Silverado also provides impressive towing and payload capacities. An assist system makes the tailgate easy to lift and prevents it from flopping harshly when it drops open. The 5.3-liter V8 hits the sweet spot, combining plenty of power with a high towing capacity and strong performance. We'd only get the 6.2-liter V8 if we had to frequently tow a heavy trailer in hilly terrain. The optional Driver Alert Package includes lane-departure warning and forward collision alert.

2007-2013
2007 Redesign Year
GMC's 2000-06 full-size Sierra has powerful, efficient engines and an inviting interior, but expect a stiff, choppy ride. A 2007 redesign brought more responsive handling and improvements to the ride, but the powertrains still aren't as refined as some competitors'.
High-end interiors have attractive fit and finish -- all have simple controls. Fuel economy from the 5.3-liter V8 and six-speed automatic are decent, and its crash test scores are improved over previous versions. Cabin access is easy, while towing and payload capacities are generous.

1999-2006
This full-sized half-ton pickup ("C" is used for 2WD versions, "K" for 4WD) was fundamentally unchanged from 1991 through 1998, though upgraded powertrains and an optional third door for extended-cab models were added in 1996. A complete redesign for 1999 brought powerful, more efficient engines and friendlier interior packaging.
Braking and handling were also significantly improved. Extended-cab models received a fourth door for 2000, and the pricey AWD C3 model, later called Denali, joined the line in 2001.
