Volvo Taps Latin America Chief Lirmann to Replace Retiring Roy

Key Details Stephen Roy, president of Volvo Group's North American trucks division and head of Mack Trucks, will retire effective August 1. Wilson Lirmann, currently leading Volvo Group's Latin American trucking operations, will assume both positions. Roy's Impact During his tenure since June 2023, Roy oversaw significant product launches including Mack's Pioneer and Keystone tractors and refreshed Anthem and Granite models. The company expanded its Roanoke Valley facility and acquired the Kings Mountain cab plant in North Carolina, regaining full assembly control. Lirmann's Background Lirmann, a Brazil native, brings nearly a decade of Latin American regional leadership. His career includes approximately 20 years in product quality and aftermarket roles before leading regional operations. Why It Matters Volvo Group is targeting 25% heavy-duty truck market share by 2030 through new model introductions and portfolio overhauls. Mack's North American market share increased to 8% in 2025 from 6% the prior year, driven by improved supply chain performance and strong vocational demand. The leadership transition positions the company to continue this growth trajectory during a critical expansion phase.
