Jeff Luke, Executive Chief Engineer for General Motors, talked to Lou Ann Hammond, CEO, Driving the Nation about the new full size trucks coming out for 2015.

The 2014 Chevrolet Silverado was named North American Truck of the Year so there are high expectations for the 2015 model. Luke talks about the 12th generation of the Chevy Suburban, a vehicle that has been around since 1935. Luke goes through the new engines, 5.3-liter and the 6.2-liter eco-tech engines, for the Chevy Silverado and Suburban and the GMC Yukon XL and Yukon Denali.
