General Motors has officially begun production of its 2027 Chevrolet Silverado and GMC Sierra full-size trucks at its manufacturing facility in Silao, Mexico. Customers in the United States can expect to receive their first deliveries of these newly manufactured vehicles within the next two months.

This launch follows a streak of 19 consecutive quarters of U.S. sales leadership for the automaker.
Production of the 2027 Silverado and Sierra has commenced in Silao, with combined truck sales rising 9% in Q3 2026 compared to the prior year. Further expansion is scheduled for 2027, with additional assembly starting in Fort Wayne, Indiana and Orion Township, Michigan.
