Volvo’s Roy to Retire; Lirmann to Head N. American Truck Ops
Roy Oversaw Mack Transformation in Second Stint as President
Key Takeaways:
- Stephen Roy will retire Aug. 1 and step down as head of Volvo Group’s North American trucks division and president of Mack Trucks.
- Roy oversaw new Mack truck launches, manufacturing expansion and improved market share during his most recent tenure.
- Wilson Lirmann, head of Volvo Group’s Latin American trucking operations, will replace Roy in both roles.
The head of Volvo Group’s North American trucks division, Stephen Roy, will step down Aug. 1, the Swedish company said April 21.
Roy, who is retiring, will also vacate the corner office at Mack Trucks. The executive led Mack as president twice during a 24-year career with Volvo Group.
Upon his appointment in June 2023 as the top regional truck manufacturing decision-maker for Mack and Volvo Trucks North America’s parent company, Roy returned to a position he held from January 2014 to March 2016.
In the more than seven-year span between those appointments, Roy was first senior vice president of uptime and customer support for the Mack and Volvo brands, followed by nearly seven years as head of Volvo Construction Equipment.
“I am very grateful for Stephen’s contribution over the years,” said Martin Lundstedt, president and CEO of Volvo Group. “In his various roles, Stephen has developed the foundation for continued growth in North America, strengthened our regionalization strategy and prepared us well for the next phase.”

Lirmann
Brazil native Wilson Lirmann will replace Roy in both roles. Lirmann is currently head of Volvo Group’s Latin American trucking operations, a position he has held for almost 10 years.
Before becoming the Latin American region’s top executive, Lirmann was head of a Volvo truck and bus dealer owned by Volvo Group after nearly 20 years in various product quality and aftermarket roles within the parent company.
During Roy’s current stint holding the reins at Mack, the truck maker overhauled its on-highway and vocational portfolios, including the launch of the Pioneer and Keystone tractors and a revamp of the Anthem and Granite models.
The period also saw Mack expand its Roanoke Valley manufacturing facility and regain complete control of its assembly process with the purchase of the Kings Mountain cab plant in North Carolina.
Volvo Group is aiming for a 25% heavy-duty truck market share by 2030, driven by the debut of the two new Mack models and the overhauls plus revamps of Volvo Trucks North America’s VNL and VNR on-highway tractors.
In 2025, Mack’s North American heavy-duty truck market share rose to 8% from 6% on the back of an improved supply chain and relatively strong vocational segment demand.
