2027 Chevrolet Silverado 1500 Production Starts October

The first units of the 2027 Chevrolet Silverado 1500 and GMC Sierra 1500 are scheduled to be Crew Cab models, with production set to begin October 12 at GM Silao in Mexico, according to sources familiar with the matter. The production timing provides the first identified build sequence for the next-generation full-size pickup trucks. GM Silao currently handles Regular Cab and Crew Cab configurations, making the Mexican facility an important launch location for the new-generation models. The initial production schedule also establishes the first confirmed body style and plant combination described in the source information.

Production plans call for Regular Cab production at GM Silao to begin February 8, 2027. Double Cab production is scheduled to follow April 12, 2027, at GM Fort Wayne Assembly in Indiana. The schedule indicates that different body configurations will enter production in stages rather than all at once. GM Fort Wayne is responsible for Double Cab and Crew Cab models, while GM Silao builds Regular Cab and Crew Cab trucks. The staggered timing therefore reflects a production allocation across the two assembly facilities as the next-generation truck program moves into broader manufacturing.

GM Silao in Mexico currently builds Regular Cab and Crew Cab trucks, while GM Fort Wayne Assembly handles Double Cab and Crew Cab production. The source information does not yet provide production timing for Oshawa Car Assembly or the recently renovated Orion Assembly Plant. That leaves the future production schedules for those facilities unspecified in the available information. The known plant assignments nevertheless establish a two-facility manufacturing framework for the initial body styles and provide a basis for tracking additional production announcements as the next-generation Silverado and Sierra programs progress.

The first Crew Cab units are expected to use GM’s new Gen 6 5.7-liter L76 V8 and 6.6-liter L78 V8 engines. The L78 is expected to represent a greater share of the early production mix. The new 5.7-liter V8 replaces the outgoing 5.3-liter L84 V8, while the 6.6-liter V8 replaces the 6.2-liter L87 V8. This engine transition is a key technical element of the next-generation trucks because the initial Crew Cab production will introduce the new V8 powertrains while replacing the corresponding outgoing engines identified in the source information.

Next-Generation Silverado and Sierra Production Schedule

The currently identified production schedule separates the next-generation truck program across body styles and assembly facilities. Crew Cab production is scheduled to start first at GM Silao on October 12, followed by Regular Cab production there on February 8, 2027. Double Cab production is then scheduled for April 12, 2027, at GM Fort Wayne Assembly. Production timing for Oshawa Car Assembly and Orion Assembly remains unspecified in the available source information.

Taken together, the scheduled production dates, plant assignments, body-style sequencing, and new V8 applications outline the initial manufacturing path for the next-generation full-size pickups. The October 12 start for Crew Cab production at GM Silao is the earliest stated production milestone, followed by Regular Cab production in February 2027 and Double Cab production in April 2027. The timing for Oshawa and Orion remains unknown. The early engine mix is also expected to favor the 6.6-liter L78, while the 5.7-liter L76 replaces the 5.3-liter L84 and the 6.6-liter L78 replaces the 6.2-liter L87.

The production sequence also establishes separate responsibilities between Chevrolet and GMC truck programs through the shared manufacturing infrastructure described in the source information. The initial Crew Cab launch at GM Silao will introduce the new V8 engines into production, while later Regular Cab and Double Cab milestones expand the manufacturing schedule. Because no dates are currently identified for Oshawa or Orion, additional production announcements will be needed to establish the complete assembly footprint for the next-generation trucks.

Industry Impact & Outlook

The staged production schedule gives the automotive industry a defined sequence for the introduction of the next-generation full-size pickup program, with manufacturing activity beginning in Mexico before expanding through additional body styles at U.S. facilities. The new Gen 6 V8 engines also represent a significant powertrain transition because they replace the outgoing L84 and L87 engines identified in the source information. Suppliers, assembly operations, and customers following the program will have clearer milestones for Crew Cab, Regular Cab, and Double Cab production, while the timing of Oshawa and Orion remains an important unresolved element of the broader manufacturing rollout.
