GMCSierra 2500HD Regular Cab 2014 - Present

　　In 2012 unveiled the fourth generation of the Sierra pickup truck and offered it as a 2014 model-year in a few grades and cab options, such as the two-door 2500HD, also known as the Regular Cab.

　　While the four-door Sierra was fit for families, the Regular Cab was mostly designed to serve as a work truck. It could tow and haul as much as any other competitor from its segment and then some more. This ability was due to the new K2XX platform, which relied on a hydroformed chassis. Thus, thanks to its stronger underpinnings, the 2500HD Regular Cab was a true workhorse.

　　Unlike its four-door sibling Crew Cab, the Regular Cab version was available with fewer features and amenities in the lowest trim level. Still, it featured the same massive grille up front flanked by squarish-looking headlights. From its profile, the angular-shaped wheel arches, both front, and rear, were cut in the wide fenders. But the automaker still thought about its customers, workers or not, and fitted the vehicle with a separate bed in the back that didn't send vibrations to the cabin.

　　Inside, GMC installed a pair of cloth seats separated by a tall center console. Since safety was one of the customers' concerns, the carmaker offered them the possibility of installing a Bluetooth-compatible sound system. The squared-looking dashboard featured a broad instrument cluster where it hosted a wide range of gauges next to the big speedometer and tachometer.

　　To power this heavy-duty truck, GMC used either a gasoline 6.0-liter V8 or a 6.6-liter V8 turbo-diesel. Regardless of the engine option, customers had to stick to a six-speed automatic gearbox.
