The frame of the upcoming Chevrolet Silverado EV “is not a unibody and it is not a body-on-frame,” according to General Motors’ chief engineer for battery-electric trucks, Nichole Kraatz. Rather, it is what the automaker is calling “Ultibody”; a nod to GM’s original Ultium EV battery platform. Forgoing a traditional body-and-frame approach to vehicle assembly, Kraatz says this new design integrates the floor of the frame with the Ultium battery structure, which makes up “a good portion of the structure and those two are connected after the body exits the body shaft.” Chevrolet’s communication lead for the Silverado, Kyle Suba said that because the battery pack is such an integral part of the vehicle’s structure, repairs “will follow different processes due to the change in architecture but will not be markedly more time consuming with the new vehicle structure.”
