General Motors’ venerable commercial vans, the Chevrolet Express and GMC Savana, will likely go electric in 2026, forecasters say.

Production of the vans is expected to remain at GM’s plant in Wentzville, Mo., when they become electric vehicles. One source expects GM to discontinue the gasoline-powered Express and Savana around the same time.

Automotive News reported last year that the vans could become EVs in 2026. No major updates are expected through 2025.

The current vans, based on a design from the early 1970s and also available as passenger haulers, have been overshadowed by newer models such as the Ford Transit, Ram ProMaster and Mercedes-Benz Sprinter. The Express and Savana were last overhauled for the 1996 model year and received a major update in 2003.

Chevy delivered just 44,355 Express vans last year as the microchip shortage slowed production. In 2019, it sold more than 77,000 Express vans. Deliveries peaked in 2005 at 127,585, according to the Automotive News Research & Data Center, which tracks sales since 2004.

GMC sold 17,744 Savana vans last year, down from more than 24,000 in 2019.

GM is expanding its commercial electric van fleet with its BrightDrop subsidiary, which has launched the Zevo 600 delivery van and plans to launch the smaller Zevo 400 next year. The BrightDrop vans will be built at GM’s plant in Ingersoll, Ontario.
