At first glance, the 2014 Chevrolet Silverado 1500 and GMC Sierra 1500 light-duty pickup trucks appear mildly evolved. A taller front end mimics current heavy-duty GM trucks, the track has been widened for greater stability, the doors have been reshaped to make the cabin quieter and the bulging wheel wells give the pickups a more rugged look.
But how do they perform as work trucks? Three new engines are addressing that challenge, in addition to an interior with greater storage, a more flexible mix of body styles, powertrains and drivetrains and a few other touches.
