GMC and Chevrolet are rolling out a variety of enhancements to their 2017 pickup truck models - including a high-end off-road GMC model dubbed the All Terrain X - along with a retooled 6.6-liter Duramax diesel engine option that offers 19% more torque than its previous incarnation. Chevrolet also found time to set a Guinness Book of World Record mark in the process, too. (All photos courtesy of General Motors)
