Despite the fact that these are the first official images depicting the Regular Cab version of the 2014 GMC Sierra, GM doesn’t say a word about it. The images come from a GM press release that focuses on busting “myths” about pickup trucks having poor aerodynamics.
Launched as a Crew Cab, just like its Chevrolet Silverado sibling, the all-new GMC Sierra will also have Regular Cab and Double Cab versions, both coming this summer. The images show the 2014 GMC Sierra testing in the wind tunnel, a rather unusual environment for a pickup truck if we’re to be honest.
Of course, the 2014 GMC Sierra Regular Cab looks exactly as it was to be expected, but the shorter cabin and longer bed make it look slightly better and more rugged than the Crew Cab version. The bed is 6.5-feet (1.98-meters) long, with an even longer bed to be offered.
As for the aerodynamics part, GM says that the 2014 Sierra spent more development time in a wind tunnel than any GMC pickup before it, thus being both more fuel-efficient and quieter inside. The release notes that keeping the tailgate up is better for the aerodynamics than rolling with it lowered. As air flows over the truck, it falls over the cab and pushes forward on the rear of the truck. With the tailgate down, the benefits of that airflow are diminished.
GM says that adding soft tonneau covers and running boards can also help improve the overall aerodynamics.
