General Motors just announced that its new EcoTec3 6.2-liter V8 engine for its new pickups has been certified by the Environmental Protection Agency at 15 miles per gallon (15.7 L/100 km) in city driving and 21 mpg (11.2 L/100 km) highway for the two-wheel drive model.
The four-wheel drive fuel economy is rated at 14 mpg (16.8 L/100 km) city and 20 mpg (11.76 L/100 km) highway. Both are improvements over the fuel economy on the 6.2-liter V-8 in the 2013 trucks, which is 13 mpg (18.1 L/100 km) city and 18 mpg (13.1 L/100 km) highway on two-wheel drive versions and 12 (19.6 L/100 km) city and 18 (13.1 L/100 km) highway on the four-wheel drive models.
The 6.2-liter V-8 will be available later this fall on the 2014 GMC Sierra Denali and SLT models, the 2014 Chevrolet Silverado LTZ and the new top-of-the-line Silverado High Country model. The engine is rated at 420 hp and 460 foot-pounds of torque (624 Nm), which GM says is the most powerful pickup engine with the highest torque in a light-duty pickup.
At the moment, GM’s new 2014 pickups also offer a V6 engine and 5.3-liter V8 engine.
