Sustainability and Market Growth
“Mack is committed to making the industrial and product investments we need to be a North American market leader,” said Stephen Roy, global president of Mack Trucks. “The expansion of the RVO plant will help us grow in a strategic market segment and support our sustainability goals.”
Virginia Gov. Glenn Youngkin announced the $14.5 million investment during an event with state and local officials at RVO. Gov. Youngkin approved a $255,000 grant from the Commonwealth’s Opportunity Fund for the project. Roanoke County offered a package of incentives totaling $842,420.
“Mack Trucks’ expansion further strengthens Virginia’s manufacturing industry ecosystem, which is a core focus of the Commonwealth’s economic development strategy,” said Gov. Youngkin. “We are proud that Mack Trucks’ initial investment in a new Roanoke County operation four years ago has yielded a second major investment. This is truly another voice of confidence in Virginia by a global industry leader.”
Mack’s investment will go toward equipment, tooling and a 72,000-square-foot building expansion, making the facility 352,000 square feet. Construction will begin in April, and the expansion project is expected to be completed in the fourth quarter of 2025.
Demand Beyond Expectations
All Mack medium-duty models are produced at RVO.
Mack launched the diesel-powered Mack MD Series in 2020 and launched the Mack MD Electric in March 2023. Adding the new model to the product lineup increased the need for more space at the facility.
“Customer demand for the Mack MD and MD Electric continues to grow beyond our expectations,” Roy said. “This investment and expansion will well-position Mack Trucks for the future.”
The diesel-powered Mack MD and MD Electric are available in Class 6 and Class 7 ratings. The Class 6 model has a Gross Vehicle Weight Rating (GVWR) of 25,995 pounds, and the Class 7 model has a GVWR of 33,000 pounds. Both models are exempt from the 12% Federal Excise Tax (FET).
Developed specifically for medium-duty applications, the Mack MD and MD Electric are built with the same focus on reliability, durability and productivity customers have come to expect from a Class 8 Mack truck.
The MD and MD Electric will meet the needs of trucking applications requiring dry van/refrigerated, stake/flatbed and dump vocations. The MD6 model does not require a Commercial Driver’s License to operate for non-hazardous payloads.
