3. Jully Burau, Vehicle Chief Engineer on the 2014 Sierra, has more than 37 years of experience at GM. So when we asked he to give us some insight as to why GMC opted to go with electric power steering, she told us, “Electric power steering gives us refinement and precision in the steering, both in unloaded and heavily-loaded conditions because we know these trucks get used in many applications." Proper steering feel is crucial, as tow ratings have been increased substantially. A 2WD Double Cab with Max Trailering Package can now tow an incredible 11,500 pounds (with 6'6" box and properly equipped). Going down the assembly line, a line worker ensures the electric power steering rack is secured to the frame.
