Chevy & GMC's New Half-Tons Are Coming
We had a chance to look over the new Chevy Silverado and GMC Sierra recently and are excited about more than just what’s under the hood. Now we can tell you a fair amount on these trucks, but there is still plenty left untold since GM has not released power or performance numbers, nor did we actually get to drive one (much less in the dirt as we’d like), but all that will be revealed soon.
The most exciting news is the new GM small-block family or, as they like to call them, the EcoTec3 engines. These are the new Gen V small-block powerplants, and the new half-tons will be offered with two V-8s and a redesigned V-6. There are a lot of body and frame changes as well, but for the most part the overall recipe stays the same: body on frame, six-speed automatic transmission, independent front suspension, and leaf-sprung rear axle.
We’ll give you a quick overview now and check back as soon as we can get behind the wheel to deliver real world drive impressions.
These three cutaway display engines show the new direct-injection gas small-block family of truck engines for the ’14 Chevy and GMC trucks. There is a 5.3L V-8, a 6.2L V-8, and a 4.3L V-6. All are brand-new, even the V-6, which hasn’t had a major overhaul in over 20 years. These engines have high compression ratios, variable valve timing, and cylinder deactivation that allow them to run on just four cylinders when needed for optimal fuel economy. In case you’re wondering, they will bolt up to older transmissions, but swapping one in your ’72 Blazer may require fancy computer work. We, like you, are already dreaming.
The interiors offer a plethora of “connectivity.” GM’s Mylink and Intelilink systems allow drivers and passengers to interface through a large touch screen featuring audio, phone, and navigation. In one of the vehicles we counted up to six different power ports for USB, 12-volt, and 110-volt charging or downloading. The transfer case shift dial is right beside (and oddly the same size as) the headlight dial on the dash along with optional trailer brake controls.
