A Legacy of Leadership: Dimitris Psillakis’s Impact
Dimitris Psillakis departs the CEO position after a distinguished 33-year career with -Benz, during which he held numerous leadership roles across Europe, South America, and Asia. His global experience and strategic insight have shaped his tenure at MBUSA, where he has served as Head of Sales for North America since late 2020 and CEO of MBUSA during a period marked by industry upheaval, global supply chain disruptions, and accelerated shifts toward electrification and digital transformation.
Under Psillakis’s guidance, Benz strengthened its dealer relationships and modernized its customer-facing operations. He championed digitalization initiatives that enhanced the customer journey, both online and in dealerships. Psillakis also played a leading role in expanding the company’s electrified lineup in North America, overseeing the introduction of all-electric and plug-in hybrid vehicles into the U.S. and Canadian markets—an essential step toward achieving Benz’s long-term sustainability goals.
In his upcoming role as Senior Strategic Adviser, Psillakis will provide continued guidance on key initiatives and work closely with the incoming leadership to ensure a smooth and seamless transition of responsibilities.
