GM has released some of the specs for the 4.3L version of the all-new 2014 Chevy Silverado and GMC Sierra pickups. The all-new 4.3L EcoTec V-6 packs 285-hp and 305 lb-ft. of torque. It also gets up to 24 mpg in rear-wheel-drive models and 22 mpg for four-wheel-drive models. GM claims that the 4.3L V6 will be the most capable standard V-6 in any full-size pickup truck. The 4.3L V-6 gives the full-size pickups the highest-available payload rating of 2,108 pounds and the highest available towing rating of 7,200 pounds.
The 4.3L V6 engine matches Ram HFE's 18 mpg city, while 4x4 Silverado and Sierra models achieve 17 mpg city, the best of any full-size pickup.
"Our V-6 has torque where you need it to get the job done," said Jeff Luke, executive chief engineer. "With 230 lb-ft of torque available at 1,200 rpm, and more torque available from 2,400 to 5,300 rpm than competitive V-6s make at their peak.
"The average pickup on the road is more than 11 years old," said Luke. "Customers driving these trucks with V-8 engines will be amazed at the power and refinement of Sierra's new EcoTec3 V-6, which has fuel economy some 30 percent better than older V-8s with comparable performance."
