2014 Chevrolet Silverado 6.2-L V8 Rated at 21 mpg

General Motors announced that the trucks equipped with the company’s new 6.2-L EcoTec3 V8 engine are officially rated at 21 mpg on highway. EPA estimates have the two-wheel-drive Sierra and Silverado models achieving 15 mpg city and 21 mpg highway. According to GM, the four-wheel-drive versions are estimated at 14 mpg city and 20 mpg highway. The 6.2-L fuel economy estimates are about 2-4 mpg lower than the two other engine options for the full-size pickups.

The 6.2-L engine produces an SAE-certified 420 hp (at 5600 rpm) and 460 lb-ft of torque (at 4100 rpm). This is the most power of any pickup engine and torque of any light duty pickup truck engine. The 5.3-L EcoTec3 V8 engine with two-wheel-drive is rated at 19 combined mpg – 16 city and 23 highway – and the four-wheel-drive versions are rated at 18 mpg combined –16 city and 22 highway. The 4.3-L EcoTec V6 achieves 17 mpg city and 22 mpg highway for four-wheel-drive versions and 18 mpg city and 24 mpg highway for two-wheel-drive models. The 4.3-L V6 is SAE-certified at 285 hp and 305 lb-ft of torque and the 5.3-L V8 certified at 355 hp and 383 lb-ft of torque.

The similar features on all these three engines include direct fuel injection, cylinder deactivation and continuously variable valve timing. 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. The Silverado, as well as the GMC Sierra, went on sale earlier this year with a host of new technologies for the Detroit-based automaker. The Silverado is the most important vehicle for the Detroit-based automaker. It is the second best-selling pickup and one of the best-selling vehicles in the U.S.
