Global Thermal Systems Market Size, Share & Trends [2026-2033]
The thermal systems market for ICE vehicles is projected to reach USD 50.28 billion by 2033 from USD 44.85 billion in 2026 at a CAGR of 1.6% during the forecast period. The market is supported by increasing vehicle production, rising thermal loads, and the need to improve energy efficiency across ICE and EVs. While vehicle electrification is creating new thermal-management requirements for batteries, motors, and power electronics, ICE and hybrid vehicles continue to represent a significant revenue base for engine cooling, charge-air cooling, HVAC, and exhaust thermal-management systems. According to ACEA in Europe, hybrid-electric vehicles accounted for 37.3% of new passenger car registrations in H1 2026, while battery-electric vehicles accounted for 20.7% of new passenger car registrations in H1 2026, highlighting the continued coexistence of multiple powertrain technologies. Increasing focus on engine efficiency and emissions control is creating new opportunities for engine therma...
