The new electric Silverado will not be a modified version of the gasoline- or diesel-powered truck equipped with batteries and electric motors. Instead, it will be engineered from the beginning as an electric-only truck, GM said, using the same Ultium electric vehicle engineering that will underlie many of the automaker’s future electric vehicles, including the GMC Hummer EV models and the Cadllac Lyriq SUV.
Engineering a vehicle from scratch for electric motors and batteries only, rather than designing it to accommodate petroleum-fueled powertrains as well, can bring numerous benefits. When a vehicle is designed to be fully electric from the beginning, storage and occupant space, as well as performance and driving range, can be optimized. It does require a big investment, though, to create an entirely separate version of that vehicle.
