We extend our gratitude to Brian for his dedication and contributions.”

Talas brings over 14 years of diverse experience at Allison Transmission, having held roles such as Customer Integration Engineer, OEM Account Manager, and Segment Manager for Europe, the Middle East, and Africa. Most recently, he served as Managing Director of East Asia Sales, overseeing markets in Japan, Korea, and Australia.

Before joining Allison, Talas worked at Daimler as a research and development engineer, focusing on engine and transmission components for Mercedes-Benz Trucks. He holds a Bachelor of Science in Mechanical Engineering from Boğaziçi University and an MBA from Bahçeşehir University.

Talas’s extensive experience and leadership will play a key role in Allison’s continued growth across the Asia Pacific region.
