The Mack Trucks Calendar Contest is back, inviting owners of the most impressive working Mack trucks to compete for a spot in the 2027 edition – including several new themed categories designed to spotlight the versatility, endurance, and toughness that define the Mack brand. 

Each winner will receive a professional photo shoot courtesy of Mack Trucks.

The contest continues the tradition of showcasing the best Mack trucks in operation across North America, highlighting the real-world jobs that Mack trucks perform every day. 

“The Mack Calendar Contest is really about the pride our customers have in their trucks and the work they do with them,” said David Galbraith, Mack Trucks vice president, global brand and marketing. “Every year we see incredible entries that capture the toughness, reliability, and character of Mack trucks in action. With the addition of new categories this year, we’re looking forward to seeing even more stories from the people who rely on Mack to get the job done.”

New Categories Added

New categories include Built for Toughest Jobs, Built for Versatility, Built for the Long Haul, and Alternative Fuels, alongside returning favorites such as Old Bulldogs Hard at Work and model-specific categories including Mack MD, MackLR, and Mack TerraPro. The contest is open to trucks in revenue operation, vehicles currently working in fleets, rather than collector or antique vehicles.

Early Entry Period Now Open

An early entry period runs through March 31, allowing participants to submit their trucks before voting begins. Voting runs from April 1 through April 30, and entries will continue to be accepted throughout the voting period. Voters can cast one vote per day in each category at the contest website.

Selected entries may be featured across Mack’s social channels, reaching more than 1,000,000 fans and followers. 

Winners to be Announced May 30

Winners will be announced on Mack Trucks social media channels by May 30. 

Mack Trucks will schedule a professional photo shoot for each winning entry to be featured in the calendar. The 2027 Mack calendar will be available later this year at mackshop.com.
