GM builds Chevy Bolts in batches of 30 to improve quality and efficiency
General Motors is building the 2027 Chevrolet Bolt in groups of 30 identical vehicles at its Fairfax plant, using a 'batch build' strategy to boost quality and simplify production.
- 30 vehicles
- 7 colors
- 3 roof configurations
What Happened
General Motors' Fairfax Assembly plant in Kansas City is using a 'batch build' process for the 2027 Chevrolet Bolt, where 30 identically equipped vehicles roll down the line together. This approach, part of GM's 'Winning with Simplicity' strategy, simplifies work for employees and suppliers, reduces variation, and ensures each vehicle is built right the first time.

After three months of production, the team continues to achieve their quality targets for electrical system checks.
- Suppliers deliver parts on a fixed seven-day schedule, improving consistency.
- Delivering parts in batches of 30 reduces the need for specialized racks, saving floor space.
- Grouping vehicles by exterior color reduces paint-purge cycles, saving time and money.
“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.”
Why this matters
Batch building reduces manufacturing complexity, improves quality, and lowers costs, which could make EVs more affordable and reliable for customers.
