Spied: 2014 Chevrolet Silverado/GMC Sierra

Introduced as 2007 models, the current Chevrolet Silverado and GMC Sierra full-size pickup twins are due for a revamp. Our spy photographers (dressed like snow leopards, we hope) have nabbed several shots of both extended- and crew-cab versions during cold-weather testing. While it’s difficult to make out much in the way of design aside from the familiar cab-in-front, bed-in-back layout, here’s a rundown of what changes to anticipate.

GM already has confirmed its investment and a few details on the fifth-generation small-block V-8, and you can count on the new engine(s) powering these trucks. As we’ve mentioned in our recent sightings of the C7 Corvette, the new small-block also will make its way into Chevy’s iconic sports car; historically, truck production volumes have supported the small-block program, making the Vette’s V-8 possible. We know all Gen V small-blocks will feature aluminum blocks, direct injection—which in turn allows for a higher compression ratio—and a “new combustion system design” that has us intrigued. In addition to the new fuel-saving tech, we’re also expecting to see the continued use of cylinder deactivation

Additionally, with the Ford F-150 bushwhacking a V-6–powered trail, we’re thinking we’ll see wider use of a six-pot in the new Chevys and GMCs. At the very least, expect the prehistoric 4.3-liter V-6 that comes standard on base 1500 trucks to die, perhaps being replaced by GM’s ubiquitous 3.6-liter direct-injected V-6. That engine currently produces up to an additional 100 hp and an extra 15 lb-ft of torque compared to the older, larger-displacement six. Remaining four-speed automatic transmissions should be swapped for six-speed units.
