The 2013 GMC Sierra Denali is the top of the line GMC pickup truck.

It comes with almost every creature comfort found on high end luxury sedans including heated seats and a heated steering wheel and all-wheel-drive.

So naturally we were curios how the Denali would do with AWD off-road.

In another fun and informative TFLcar video we take the 2013 GMC Sierra Denali on our standard off-road trail to determine if an AWD pickup is as capable as a 4X4 pickup in the snow, mud and rocky terrain of the Colorado Rocky Mountains.

CONFIDENCE ON DEMAND

Sierra Denali is available with electronic All Wheel Drive that helps detect wheel slippage and, in a fraction of a second, responds by sending power to both the front and rear wheels to help enhance traction.

EATON^® AUTOMATIC LOCKING REAR DIFFERENTIAL

No other competitor in its class offers a standard fully automatic locking rear differential for on or off-road use:

• Senses a difference in speed between left and right rear wheels
• Locks to turn both wheels in unison” – – GMC.com

So, we know that they are very proud of their rear end. Yay!
