Chevy releases EcoTec3 4.3l V6 Engine Specs

Tuesday, May 7th 2013. | Review

We’ve been waiting anxiously for Chevy to release the specs on its new family of EcoTec3 engines. It is important data on many levels. We’ll get to find out in a number of ways what we can expect from these engines in the new line up of 2014 Chevy Silverado’s and GMC Sierra’s. In this article we’ll start with the base engine, the 4.3L EcoTec3 V6. We will follow up short with articles for the EcoTec3 V8′s which will be 5.3L and 6.2L in displacement.

EcoTec3 4.3-Liter V-6

For its base engine, Chevy does not dissapoint! The 2014 will grace showroom floors near you with a class-leading (among base v6′s) torque number of 305 ft-lb’s and an impressive 285 horsepower. That horsepower number may not be class-leading, but its the torque where it matters in a pickup truck. It is torque that delivers off-the-line acceleration and it is very important to hauling and trailering/towing performance.

Speaking of towing and hauling, the 2014 SIlverado will, again, not dissapoint. Here too it puts down class-leading numbers of a 7,200 pound towing rating, that number is 500 pounds higher than a Ford F-150 with its 3.7l base v6 and a whopping 700 pounds better than a Ram 1500 with base v6.

Another number we are anxious to know, especially for the v6, is fuel efficiency, unfortunately Chevy has not released numbers yet, but promises us estimates soon. I’m sure we are all anxiously waiting for this number, especially for the 4.3l V6 where Chevy has a shot at yet another class-leading figure. For more information on the technology you can expect in an EcoTec3 engine navigate here. A couple of highlights include cylinder deactivation (or active fuel management) and the use of direct injection.
