The 5.3 liter EcoTec3 V8 engine in the 2014 Chevrolet Silverado and GMC Sierra 1500 produces a hefty 355 horsepower and 383 lb-ft of torque. This workhorse of an engine enables the truck to tow up to 11,500 pounds and carry an additional 2,102 pounds in the bed, but there is one more area where the 5.3 liter V8 excels: fuel efficiency.
Thanks to new technologies like continuously variable valve timing, direct fuel injection and active fuel management, the 5.3 liter EcoTec3-equipped Silverado and Sierra are the two of the most fuel efficient full-size V8 pickup trucks on the market. Seeing as so many truck owners take their vehicles cross country, whether it be for work or vacation, owners of GM’s new pickups will appreciate having a thicker wallet and not having to stop at the pumps as often.
GM has put together a video featuring two 2014 Silverado owners, Realtree Roadtrips and Bone Collector host Nick Mundt and Silverado powertrain engineer, Nick Smith. Mundt is out on the road 300 days a year, so as you can imagine, he appreciates the added efficiency of the EcoTec3. Smith also likes to take a road trip or two, and explains how VVT, direct injection and active fuel management work to save GM’s customers money. Check out the video below.

My dad insisted that he should have been on one of these commercials with his 2004 Silverado 2500HD Crew Cab LS 6.0L 4X4. He took that thing to hell and back! It now has 136K hard miles and is still not just running tough, but strong as well. .
He is going to the dealer to buy a 2015 2500HD Crew Cab Standard Box 6.6L LT Z71 in awhile. Hopefully these new trucks live up to expectations! I am sure they will. .
