DETROIT – The same technology that makes the all-new 2014 Sierra’s 4.3L EcoTec3 V-6 the most capable standard V-6 in any full-size truck also makes it a segment leader in fuel economy, allowing owners to go farther on a single fill-up.

EcoTec3 engine technology enables 2WD 4.3L V-6 Sierra models to match Ram HFE’s 18 mpg city, while 4x4 models achieve 17 mpg city, the best of any full-size pickup. EPA highway estimates are highly competitive: 22 mpg for 4x4 versions, and 24 mpg for 2WD models.

Sierras equipped with the 4.3L V-6 also will be the most capable trucks with standard V-6 engines, with highest available payload rating of 2,108 pounds and the highest-available towing rating of 7,200 pounds.

“The 2014 Sierra offers capability, efficiency and refinement regardless of trim level or engine choice,” said Tony DiSalle, vice president of GMC Marketing. “All of the technology that makes this our most efficient half-ton pickup ever comes standard for every customer.”

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

“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.”

The new V-6 joins Sierra’s 5.3L EcoTec3 V-8 , with EPA estimated highway fuel economy of up to 23 mpg, the best estimates of any V-8 pickup, and better than the 22 estimated highway mpg for the Ford EcoBoost turbo V-6.

A new 6.2L EcoTec3 V-8, available this fall, will be the most powerful engine offered on any light-duty pickup, with an estimated 420 horsepower and 450 lb-ft of torque, and a maximum available towing rating of 12,000 pounds.
