The passenger vehicles segment held a 72.4% share in 2025 and is projected to grow at a CAGR of 4.2% through 2035. This leadership position is supported by high global production volumes across vehicle categories and the rapid adoption of electrified passenger vehicles. Increasing demand for enhanced in-cabin comfort, improved energy efficiency, and extended driving range is driving the integration of advanced thermal management solutions. Regulatory pressure related to fuel efficiency and emissions is also encouraging the adoption of lightweight and highly integrated thermal system architectures in passenger vehicles.
The OEM segment held a 72% share in 2025 and is expected to grow at a CAGR of 4% from 2026 to 2035. This dominance is attributed to the complexity of integrating advanced thermal systems within modern vehicle platforms, particularly for electric and hybrid models. Thermal components are increasingly designed and optimized during the vehicle development stage, making original equipment manufacturers central to system implementation. Strong supply partnerships and large-scale vehicle platform development further reinforce the importance of OEM channels, while the aftermarket remains relatively limited due to the technical complexity of these systems.
