The thermal systems market is increasingly being shaped by the transition from component-level cooling and HVAC toward integrated, software-controlled thermal-energy management across ICE, hybrid, and electric powertrains. In ICE vehicles, higher power density, turbocharging, downsizing, and tighter efficiency requirements are increasing the need for precisely controlled engine, charge-air, transmission, EGR, exhaust and cabin thermal circuits. Further, in hybrid and EV platforms, thermal complexity is expanding as battery, e-motor, inverter, OBC/DC-DC, cabin HVAC and charging systems must be maintained within optimized temperature windows. This is accelerating adoption of liquid cooling, heat pumps, high-efficiency e-compressors, variable-speed coolant pumps, smart valves, advanced heat exchangers, battery preconditioning and integrated thermal modules. For instance, Mahle has developed a compact module integrating the compressor, heat exchanger, coolant pumps, sensors and valves, with the company targeting up to 20% higher range in cold conditions compared with electric-heater architectures.

The growing adoption of premium comfort and personalized thermal features is expanding thermal-system content beyond conventional HVAC. Features such as heated steering, heated/ventilated seats, rear A/C, and localized cabin conditioning are increasingly moving into mid-range SUVs and larger passenger vehicles as OEMs use thermal comfort as a vehicle-differentiation lever. At the same time, localized heating/cooling and intelligent seat-climate technologies can deliver occupant comfort with lower energy consumption than conditioning the entire cabin. For instance, Gentherm's ClimateSense integrates localized heating and cooling with central HVAC to enable personalized thermal comfort while improving energy efficiency. The shift toward personalized, energy-efficient cabin thermal management, particularly in hybrid and EV platforms where HVAC energy directly impacts vehicle efficiency, is creating new opportunities for higher thermal content per vehicle.
"BEV segment to lead electric & hybrid vehicle thermal systems market"
The battery electric vehicle (BEV) segment is expected to lead the thermal systems market as the architectures of BEVs require the highest level of integrated thermal control across the battery, e-motor, inverter, e-axle, charging system and cabin. The shift toward larger batteries, higher power density, 800V-1,000V architectures and ultra-fast charging is increasing the need for battery preconditioning, liquid cooling, advanced cooling plates and high-capacity thermal circuits. At the same time, the move toward CTP/CTC battery architectures, higher-performance e-drives and larger SUVs is increasing thermal uniformity and heat-flux management requirements. Since BEVs lack ICE waste heat, heat pumps, waste-heat recovery and intelligent HVAC control are also becoming critical for maintaining cabin comfort without significantly reducing driving range. Regionally, China and broader Asia are at the forefront, supported by high BEV penetration, battery manufacturing and rapid deployment of high-voltage/ultra-fast charging technologies, while Europe is advancing premium, high-efficiency thermal architectures. Overall, thermal management is shifting from component-level cooling toward integrated, software-controlled vehicle thermal-energy management, giving BEVs the highest thermal-system content and value potential per vehicle.
"Waste heat recovery segment to witness highest growth rate during forecast period"
Waste heat energy recovery is emerging as one of the fastest-growing thermal-management technologies as OEMs increasingly shift from dissipating excess heat to recovering and redistributing thermal energy across the vehicle. In ICE vehicles, heat from exhaust gases and engine coolant can be recovered for cabin heating and thermal conditioning, improving overall thermal efficiency and reducing reliance on auxiliary heating systems. In HEVs and PHEVs, frequent engine stop-start events and EV-mode operation reduce the availability of conventional engine waste heat, increasing the importance of recovering heat from the engine, e-motor, and power electronics and coordinating it with heat-pump systems. In BEVs, heat generated by the e-motor, inverter, battery, and e-axle can be recovered and redirected to the cabin or battery, reducing electrical heating demand and helping preserve driving range, particularly in cold conditions. This is driving the transition from standalone heat-recovery components toward integrated thermal modules, heat pumps, intelligent valves, and software-controlled heat-flow management that can optimize the use of available thermal energy across the vehicle. Technologically, the market is moving toward multi-source heat recovery, integrated thermal loops, intelligent valves, heat pumps, and predictive software that dynamically determine where recovered heat can deliver the greatest energy benefit. Strategically, this is shifting thermal management from component-level heat recovery toward whole-vehicle thermal-energy orchestration, enabling OEMs to capture efficiency gains across ICE, HEV/PHEV, and BEV platforms while improving cabin comfort and reducing energy consumption. Therefore, waste heat energy recovery is expected to become a core element of whole-vehicle thermal-energy management, particularly as larger batteries, higher-power electric drivetrains, and faster charging increase the importance of efficient thermal-energy utilization.
"Europe to be second-largest market for thermal systems"
Europe is estimated to be the second-largest thermal systems market, owing to its automotive industry combining rapid electrification with a strong premium/SUV vehicle mix and stringent efficiency requirements, which are increasing thermal-system content per vehicle. EV sales grew by more than 30% in Europe in 2025, reaching 28% of new-car sales, while the availability of EV models increased by nearly 35%, accelerating the adoption of battery cooling, heat pumps, e-compressors, and integrated thermal architectures. The growing penetration of larger SUVs, premium vehicles, and electrified PHEV/HEV platforms is further increasing thermal loads across batteries, e-powertrains, cabin HVAC, and high-power electronics. Technologically, European OEMs are moving toward 800V architectures, fast-charging thermal control, multi-loop cooling, waste-heat recovery, integrated thermal modules, and predictive thermal-energy management to improve range, charging performance, and cabin efficiency. Regulatory pressure is also a major catalyst, with EU CO2 standards tightening from 2025, while the regulatory framework continues to push OEMs toward lower-emission and zero-emission vehicles. HVAC efficiency improvements can also qualify as EU eco-innovations from 2025. Consequently, Europe's thermal-management opportunity is shifting from conventional engine cooling toward highly integrated, energy-efficient thermal architectures that simultaneously manage battery, e-drive, cabin, and charging loads, supporting its position as the second-largest and technologically advanced regional market.
