LAS VEGAS - General Motors will unveil the electric-powered version of its best-selling vehicle during the Consumer Electronics Show on Wednesday.

GM CEO Mary Barra will make a keynote address during the presentation of the Chevrolet Silverado EV at noon, which will be streamed live on the company’s Exhibit Zero website.

Less than one hour later, GM will begin taking reservations from consumers for the pickup truck, which is expected to be available by mid-year.

Chevrolet says the truck will offer a Four-Wheel Steer chassis feature that allows steering on all four wheels, enabling increased agility and turning radius at low speeds, improved handling and stability at higher speeds, allowing tight turns.

Also available will be a fixed-glass roof, offering increased visibility and headroom for both front and rear passengers

In addition to new interiors, Super Cruise, and new off-road and luxury packages, GM says the electric Silverado will offer an estimated range of more than 400 miles on a full charge.

GM says it has designed the new vehicle as an EV from the ground up, using the Ultium Platform.

The first Ultium battery plant is nearing completion in Lordstown, Ohio.

Plans are also underway to build an Ultium manufacturing plant in Spring Hill, Tennessee.

Last year the automaker said it also planned to build a third and fourth Ultium factory.
