Mack Trucks has announced the winning entries of the 2025 Mack Trucks Calendar Contest. Twelve trucks, each representing a month in the year, will be featured on the calendar.

Thousands of Mack fans chose the winners from 177 submissions in seven categories — Mack Anthem, Granite, Legacy, LR, Mack MD, Pinnacle, and TerraPro. These represent the truck models currently available in the Mack lineup, except for Legacy, the category for Mack models no longer in production but still in operation with customers.

In honor of Mack’s 125th anniversary, this year’s contest included a special category for the oldest Mack still in revenue operation.

The winning dozen will be professionally photographed by Mack for the 2025 edition of the calendar.

“It was exciting to see how involved everyone was in this year’s contest,” said David Galbraith, Mack Trucks vice president, global brand and marketing. “We received a record 432,000 votes this year, which is particularly special to us considering the 125th anniversary of Mack in 2025. The strength of the Mack community, even after all these years, shows an affinity for the brand that is unmatched in virtually any industry.”

To be eligible for the calendar, each truck, including the Legacy truck models, must currently be in operation in a business or trucking company; the truck must be in routine use; and trucks may not be collector or show trucks that are no longer licensed for commercial use.
