The big news in the world of GM trucks this year was the introduction of its new full size pickups, but the news is literally bigger for 2014.

That’s when the next generation of the heavy duty versions of the Chevy Silverado and GMC Sierra hit the road with an updated look and improved capabilities.

Both trucks get new bodywork that features supersized takes on the look of their light duty siblings, and includes their clever CornerStep rear bumpers and EZ lift tailgates.

The cabins have been substantially overhauled, as well, with increased passenger space and a higher level of refinement, particularly in the top of the line GMC Denali trim.

Underpinnings are largely carryover, and the choice of 6.0-liter gasoline and 6.6-liter diesel engines remains the same, but maximum payload and towing capabilities have been increased due in part to improved engine cooling systems.

Trailer sway control is now standard, while the available exhaust braking and auto grade braking systems have been integrated with the cruise control.

Pricing has not yet been announced, but you won’t have to look too hard for these huge trucks when they start filling up showrooms next spring.
