Overview
The GMC Sierra 1500 – when taken in combination with its Chevrolet Silverado 1500 twin – is one of the most popular vehicles in the United States.

The Sierra 1500 Denali is available only in the Crew Cab bodystyle, either with a short or a standard cargo box, and in rear-drive or four-wheel drive. Three different engines are available, from the 5.3-liter V-8, the 3.0-liter Duramax inline six-cylinder diesel, or the 6.2-liter EcoTec V-8 (in four-wheel drive only). All of the trucks feature a 10-speed automatic transmission.
Key Features
- 355hp 5.3-liter V-8 standard, standard 10-speed automatic transmission
- unique Denali chrome grille, six-inch chrome assist steps, chrome vertical recovery hooks, dual-projector LED headlamps, and GMC running lamps with signature C shape
- 40 inches diagonal of combined driver-focused digital displays, WiFi hotspot, Amazon Alexa built-in capability
- Perforated Forge Leather seating surfaces, patterned aluminum trim and chrome accents, premium instrument panel and door trim with chrome and open-pore walnut detailing

Ruben M. S
Reviewed a 2011 GMC Denali Crew Cab AWD on Jul 28, 2013
I've had this truck for 2 1/2 years and have had no mechanical issues of any kind. It has been on long distance road trips and provided us comfort, lots of room, and reliability. I will be buying a new Denali sometime soon.
