General Motors previewed all-new versions of its GMC Sierra and Chevrolet Silverado full-size pickups in a flurry of media releases today.

The 2014 GMC Sierra will be “the most powerful, most advanced and most refined truck in the brand’s 110-year history,” according to the GMC presser. It will be outfitted with GMC’s Intellilink infotainment system as well as the longest list of standard features ever included on a GMC pickup truck, the release said.

The 2014 Chevy Silverado will continue its tradition of being the everyman’s truck and will be available at lower prices than its GMC sister, if past pricing strategy is any indication. However, those wanting to tech it up will have the option of Chevrolet’s MyLink infotainment system controllable by natural voice commands– “no phrases to remember” boasts the Chevy press release– or via buttons on the steering wheel, knobs and buttons on the dash, or even via touchscreen technology, for those who opt for the up-option 8-inch MyLink screen.

The trucks will share engine and powertrain details, as is the norm for the Silverado and Sierra twins. The base V6 remains a 4.3-liter unit. While that displacement is familiar to any GM truck fan, the engine is not– it’s an all-new “EcoTec3″ unit that GM promises will have ample power and torque for moving a loaded crew cab truck down the road while towing a trailer.

Also familiar to GM truck aficionados will be the V8 engines’ 5.3- and 6.2-liter displacements, but here again are the engines new-and-improved, according to GM. Both the V8s and the base V6 will have the ability to run on only four cylinders when throttle loads are light in an effort to gain all-important fuel efficiency and also partially to make for a smoother, quieter ride.

GM said it will launch three new EcoTec3 engines in the 2014 GMC Sierra and Chevrolet Silverado full-size pickup trucks. The engines come in three familiar displacements– 4.3, 5.7, and 6.2 liters– but share only a few parts with the previous truck engines, according to a GM press release.

All of the engines feature direct injection and continuously variable valve timing, as well as a relatively stiff 11:1 compression ratio. That last detail– achieved on regular unleaded, no less– was doable thanks to the widely variable valve timing and should help the engines make more power while returning better fuel economy numbers, the GM release said.

While this post is just an overview of the information GM has released about the new trucks’ tech features so far, we’re looking forward to the opportunity to dive deeper and learn more about the trucks in the future. For one thing, we’ll be eagerly awaiting EPA fuel economy numbers and SAE horsepower and torque ratings for the new trucks, none of which had been released at the time of this writing. Watch this space.
