Take one look inside the all-new 2014 GMC Sierra and you’ll see clearly why this is the new standard in truck interiors. Sierra’s interior brings comfort, refinement and convenience to a whole new level. From innovative cargo-box features and a stronger foundation, to striking new styling featuring details that make it truly stand apart, the 2014 Sierra is clearly a respected leader in the truck market….by example. Sierra owners expect outstanding power when trailering and hauling, and excellent efficiency when highway cruising or commuting to work. The all-new Sierra EcoTec3 engines deliver just that. Sierra’s available EcoTec3 5.3L V8 engine offers the best V8 fuel economy in any fullsize pickup3 at an EPA-estimated 16 MPG city and 23 MPG highway (2WD). All three engines feature three sophisticated technologies that work together to optimize power and fuel efficiency. No other competitive pickup offers all of these technologies standard in any of their engines.
