2014 Chevy Silverado trio of engines

Sheryl Balsley, assistant chief engineer of small block engines, showed www.drivingthenation.com the 2014 Chevy Silverado three engines available in the new Silverado, all-new EcoTec3 engines, a V-6 and two V-8s without the cost of turbocharging.

From Chevrolet:

New shear-style body mounts tune out both up-and-down and side-to-side movement for a quieter, more comfortable ride. The compression ratio is 11:1 on regular fuel on the 4.3 and 5.3. Double cab and crew cab models have a set of hydraulic body mounts to further isolate the cabs. Combined with numerous other acoustic and NVH (noise vibration and harshness) enhancements, the intended result is a solid, refined feel with no loss in traditional truck capability.

The 4.3L V-6 SAE-certified at 285 horsepower (212 kW) and 305 lb.-ft. of torque (413 Nm), a 5.3L V-8 certified at 355 horsepower (250 kW) and 383 lb.-ft. of torque (519 Nm), and later this year, a new 6.2L V-8.

All three EcoTec3 engines feature direct fuel injection, Active Fuel Management (cylinder deactivation) and continuously variable valve timing, a combination not found in competitive trucks. The engines also use a compact overhead-valve design and weight-saving components such as aluminum blocks and cylinder heads, to reduce mass, for additional energy savings

All three provide the proven power, torque and dependability of a large-displacement engine, seamlessly switching to four-cylinder mode to save fuel during light-load driving. The 5.3L V-8 has EPA“estimated fuel economy of up to 23 mpg highway (2WD models), the best of any V-8 pickup, and better than Ford EcoBoost V-6.

Silverados equipped with the 4.3L V-6 will have towing ratings up to 7,200 pounds, the highest for any base V-6 in the segment. Silverados equipped with the 5.3L V-8 and the max towing package, available later this year, will have towing ratings of up to 11,500 pounds, which is more than any light-duty pickup currently on the market.
