General Motors Mexico Starts 2027 Silverado and Sierra Production

General Motors Mexico Begins Production of 2027 Silverado and Sierra 1500

General Motors Mexico has begun production of the all-new 2027 Chevrolet Silverado 1500 and GMC Sierra 1500 at its Silao Assembly plant in Guanajuato, according to a report dated October 13. The facility is the first General Motors plant in North America to manufacture the new-generation pickup truck models. Production began with Crew Cab versions, with the first units rolling off the assembly line in October. The launch establishes Silao as the initial manufacturing location for both vehicles and precedes the planned addition of production at GM's Fort Wayne Assembly plant in Indiana in early 2027.

Silao to Remain the Sole Production Site Through 2026

General Motors will keep production of the 2027 Chevrolet Silverado 1500 and GMC Sierra 1500 exclusively at the Silao Assembly plant through the end of 2026. The Guanajuato facility will manufacture Crew Cab and Regular Cab configurations. This production arrangement makes Silao the sole manufacturing location for the new-generation models during the initial phase of the program. The planned timeline provides a defined transition period before manufacturing expands to another North American facility, although the source does not specify production volumes, capacity targets, or the expected output split between the two plants.

Fort Wayne Assembly to Join Production in 2027

General Motors plans to add its Fort Wayne Assembly plant in Indiana to the production program in early 2027. Once the facility joins manufacturing, it will produce Crew Cab and Double Cab variants of the Chevrolet Silverado 1500 and GMC Sierra 1500. The planned allocation differs from Silao's configuration, where Crew Cab and Regular Cab models will be manufactured. Both plants will therefore contribute to production of the new-generation pickups, while their assigned cab configurations will not be identical. The source does not provide further details about production capacity, staffing, investment, or the precise date when Fort Wayne manufacturing will begin.

Silao Prepared Its Operations for the New Models

Before beginning the new production program, the Silao complex temporarily suspended Silverado and Sierra manufacturing during periods in July and August. The interruptions allowed the facility to carry out operational preparations for the new-generation models. The source does not identify the specific equipment changes, production-line modifications, workforce measures, or other activities undertaken during those periods. The reported preparations preceded the October production start and formed part of the transition to manufacturing the 2027 model-year pickups. No further information was provided about the duration of each suspension or its effect on total production volumes.

Production Allocation and Manufacturing Timeline

The reported production plan establishes a phased manufacturing arrangement for the 2027 Chevrolet Silverado 1500 and GMC Sierra 1500. Silao is responsible for the initial production period, while Fort Wayne is scheduled to join in early 2027. The plants will also have different cab-configuration assignments, with Silao producing Regular Cab and Crew Cab versions and Fort Wayne producing Double Cab and Crew Cab versions. The shared Crew Cab configuration will be manufactured at both facilities. The following table summarizes the plant assignments and timing reported in the source.

Industry Impact & Outlook

The production launch establishes a phased manufacturing arrangement for General Motors' next-generation full-size pickups across facilities in Mexico and the United States. Silao's exclusive role through the end of 2026 makes its operational readiness central to the initial production period, while the planned addition of Fort Wayne in early 2027 will broaden the manufacturing footprint. The different cab-configuration assignments also define distinct responsibilities for the two plants, with Crew Cab versions planned at both locations. For suppliers, production planners, and other stakeholders connected to these vehicles, the next significant milestone is Fort Wayne's entry into the program. The source does not establish projected sales, output increases, investment levels, or employment effects.

Frequently Asked Questions

Where are the 2027 Chevrolet Silverado 1500 and GMC Sierra 1500 being manufactured initially?
General Motors began manufacturing the new-generation Chevrolet Silverado 1500 and GMC Sierra 1500 at its Silao Assembly plant in Guanajuato, Mexico. The facility is the first General Motors plant in North America to manufacture these new-generation models. The first units, consisting of Crew Cab versions, rolled off the production line in October. Silao is scheduled to remain the sole production location for both vehicles through the end of 2026, before manufacturing is planned to expand to Fort Wayne Assembly in Indiana in early 2027.

When will Fort Wayne Assembly begin producing the new Silverado and Sierra?
General Motors plans for its Fort Wayne Assembly plant in Indiana to join production of the 2027 Chevrolet Silverado 1500 and GMC Sierra 1500 in early 2027. Until the end of 2026, Silao will remain the sole production location for the new-generation models. Fort Wayne's planned entry will add a second manufacturing facility to the program. The source identifies early 2027 as the expected timeframe but does not provide a specific start date, production volume, or detailed schedule for the transition between the facilities.

Which cab configurations will Silao and Fort Wayne manufacture?
The two plants will have different cab-configuration assignments under General Motors' reported production plan for the 2027 Chevrolet Silverado 1500 and GMC Sierra 1500. Silao Assembly in Guanajuato will manufacture Crew Cab and Regular Cab versions. Fort Wayne Assembly in Indiana is scheduled to produce Crew Cab and Double Cab variants when it joins the program in early 2027. Crew Cab models will therefore be produced at both locations, while Regular Cab production is assigned to Silao and Double Cab production is assigned to Fort Wayne under the reported arrangement.

Why did Silao temporarily suspend Silverado and Sierra manufacturing in July and August?
The Silao complex temporarily suspended Chevrolet Silverado and GMC Sierra manufacturing during periods in July and August to prepare its operations for the new-generation production program. These preparations took place before the October production start for the 2027 models. The source confirms the purpose and timing of the interruptions but does not detail the specific operational changes, equipment installations, production-line modifications, or workforce activities involved. It also does not state how long each suspension lasted or quantify any resulting impact on production volumes at the facility.
