We haven't even gotten used to the 2012 GMC Sierra at Duke Automotive in Suffolk, VA and GM is already working on a 2014 upgrade.  Full details were not discussed publicly by the auto maker at 2012's Detroit Auto Show, but we know this next generation of pickups will pack more power, without skimping on fuel economy.  

These trucks will receive better fuel economy thanks to a direct injection small-block V8 from the company.

Front Wheel Drive and 4WD variants will be available. HD models that attract municipal and constriction buyers, will arrive for the 2015 model year. Other specifics have yet to be released.

These trucks will receive complete overhauls inside and out. There will be a body styling redesign, making it aerodynamic. Inside, wood trim and fun gadgets will adorn Sierra's dash.

Stay tuned for the updates as we hear more!
