In 1900, Jack and Gus Mack opened their first manufacturing plant in Brooklyn, New York.
Their first successful vehicle was a bus, and in 1902 they incorporated as the Mack Brothers Company. Their dream that started in that small Brooklyn shop has grown into a global transportation powerhouse and an icon of Americana.
In the decades that followed, Mack Trucks would be used to help build the Hoover Dam, the Empire State Building and as a tool for the Allies in the First World War.
This year, the company marks the 125 anniversary since the doors to the Mack’s brothers’ factory first opened.
“Every Mack truck that rolls off our assembly line carries forward a legacy of grit, innovation and that unmistakable bulldog tenacity that has defined our brand since 1900,” said Stephen Roy, President of Mack Trucks.
The Bulldog
The iconic Mack bulldog — now synonymous with the company worldwide — earned its stripes on the battlefields of the First World War. British soldiers nicknamed the Mack AC models “bulldogs” for their reliability under fire.
“We really earned a very good reputation for durability and reliability out on the battlefields by getting troops and supplies where they needed to be when they needed to be there,” said Jonathan Randall, President of Mack Trucks North America.
Mack embraced the nickname and adopted the bulldog as its corporate symbol in 1921.
Mack’s then Chief Engineer, Alfred Fellows Masury, carved the first Mack Bulldog hood ornament from a bar of soap during a hospital stay in 1932 to pass the time.
Innovation at Mack
Throughout its history, Mack Trucks has developed numerous industry firsts for the trucking and transportation industries.
“It’s been a pretty good century and a quarter, and we’re really proud of the fact that there are not many companies that define an industry and stay around for that long,” Randall said.
For example, Mack pioneered the concept of integrated powertrains, combining engines, transmissions and axles into a unified system in the 1920s. The following decade, the company introduced power brakes and power-assisted steering, setting new safety standards.
“We’re incredibly proud. Not only from the standpoint of just the fact that we’ve lasted that long, but the amount of innovation that it takes to remain relevant for that long,” Randall said.
“We’ve been incredibly innovative throughout the years.”
Mack Trucks innovations throughout the years also includes:
- 1953: Launched the Thermodyne engine, establishing new benchmarks for power and efficiency
- 1967: Introduced the Maxidyne engine, featuring high-torque rise and constant horsepower
- 1979: Debuted the Econodyne engine, marking a new era in fuel efficiency
- 2010: Introduced the mDRIVE automated manual transmission to improve driver productivity and fuel efficiency
- 2016: Launched the mDRIVE HD 13-speed, making Mack the first truck manufacturer in North America to offer low reduction creeper gear ratios in a proprietary automated manual transmission
- 2022: Launched the zero tailpipe-emission LR Electric refuse truck
- 2023: Expanded electric offerings with MD Electric medium-duty truck
“Each of these innovations represents more than just technological advancement,” Randall said. “They represent Mack’s dedication to solving real-world challenges for our customers, while continuously pushing the boundaries of what’s possible in trucking.”
Mack Museum
The history of Mack’s innovation is preserved at the Mack Trucks Historical Museum in Allentown, Pennsylvania. The museum, which celebrated its 40th anniversary last year, welcomes about 10,000 visitors each year to see its collection of vintage trucks and detailed archives.
“What’s remarkable about Mack’s 125-year journey is how the core values have remained constant even as the technology has evolved,” said Doug Maney, Curator of the Mack Trucks Historical Museum.
“In the museum, we have trucks from every era – from early chain-driven vehicles to modern electric models. While the technology depicts the story of innovation, it’s the countless tales of reliability and the determination of owners, drivers and dealers that truly define the Mack legacy. These stories exemplify that whether it’s a 1900 or 2025, a Mack truck is built to get the job done.”
Mack in Canada
Mack trucks are sold and serviced in more than 45 countries worldwide.
Yet, the company remains committed to manufacturing in the United States. The Lehigh Valley Operations (LVO) facility in Pennsylvania, assembles every Mack heavy-duty truck. The Roanoke Valley Operations (RVO) facility in Virginia, produces the company’s medium-duty trucks.
North America represents about 90 per cent of the company’s volume. Canada accounts about 25,000 to 30,000 trucks per year. In 2021, Mack marked 100 years of business in Canada.
“It’s an incredibly important market and we’ve got a great distribution network up there to help handle it,” Randall said.
Like the United States, a large portion of the Canadian market is made up of on-highway trucks. However, Mack’s trucks have found success in Canadian off-highway applications, as well as niche markets like ice road trucking, dump trucks, ready-mix and booms.
“We do well there because of the terrain. The applications are pretty darn rugged,” Randall said.
On the jobsite
About half of the trucks produced by Mack are sold for vocational applications.
“Even a percentage of our tractors go into vocational applications, like oil fields and things of that nature as well. It’s a big, big portion of our business,” Randall said.
In 2020, Mack introduced its MD Series expanding their traditional range for local delivery, construction and vocational applications.
“Our medium duty business has taken off,” Randall said. “We launched that in 2020, and it has surpassed our expectations just in the few short years we’ve had it out there.”
The next 125
As Mack enters its next 125 years, the company is looking to lead the charge toward sustainable transportation. The deployment of the LR Electric refuse trucks in major cities has shown that zero tailpipe-emission vehicles can be used in the most demanding applications.
In addition, the MD Electric series is transforming medium-duty applications from beverage delivery to local freight.
“Our 125th anniversary isn’t just about celebrating our past — it’s about driving toward an even more innovative future,” Roy said. “The same spirit that inspired Jack and Gus Mack to build their first vehicle continues to drive us forward as we pioneer electric and autonomous technologies for the next generation of transportation. Together, we’re moving and building a better world.”
