How General Motors is Batch Manufacturing the Chevy Bolt EV

General Motors is manufacturing the Chevrolet Bolt EV in batches of 30 at its Fairfax Assembly and Stamping Site in Kansas City, Kansas.

The automotive manufacturer has implemented a process a batch build process for the 2027 Chevrolet Bolt, marking a shift in how EVs are assembled at scale.

This approach forms part of GM's manufacturing strategy named "Winning with Simplicity", which reduces complexity so teams can work more efficiently, protect quality and lower the cost of building new EVs.

GM's EV production line

On the plant floor, 30 similar Bolt LT or RS models, all in the same colour, roll down the line in one unbroken sequence. This batch-build approach simplifies the complex process of assembling modern high-tech EVs.

According to GM, its teams are meeting their monthly electrical first-time quality targets, which is a key electrical-system check for EVs.

The system has offered improvements in supply chain, floor space and paint operations. The company's "clone process" has helped quality control across the production line.

Michael Youngs, General Motors' Fairfax Plant Director, says: "We're proud to be the first GM plant in North America to adopt batch build. It's paying off with quality and efficiency. The lessons we are learning here will carry over to the next products we build here, and we believe it will also carry on to other GM plants in the future.
