CR's Take

The GMC Sierra (and its Chevrolet Silverado twin) will be replaced this fall by a truck based on the new Chevrolet Tahoe. The 2004 Z71 Silverado that we tested had a stiff, choppy ride. Other trim lines ride slightly better. Braking is adequate, and fit and finish is unimpressive. The powertrain isn't as smooth as competing models from Toyota or Nissan. The Sierra's assets are a selectable, full-time, four-wheel-drive system and a generous load capacity. The Denali is an expensive AWD model with a 6.0-liter V8. The extended-cab hybrid version has a claimed 12 percent boost to fuel economy.

Model History

2019-Present

Current Generation

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. The ride is stiff and snappy, but 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 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 on higher trims. Updates for 2020 include an available 3.0-liter turbodiesel six-cylinder engine paired with a 10-speed automatic transmission. The diesel pulls strongly, feels refined, and returns 23 mpg overall. Other changes for for 2020 saw suspension tweaks improving the ride, and the availability of adaptive cruise control. FCW, AEB with pedestrian detection, and BSW became standard for 2022.

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

1999 Redesign Year

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.
