Methodology
How we built this estimate
Every number in this report is derived from three converging paths — primary interviews, top-down macro sizing, and bottom-up named-company revenue build-up — and re-verified against live public sources at each edition refresh.
-
Primary research
Structured analyst interviews with buyers, vendors, and distributors across the value chain — top-tier OEMs, mid-market integrators, and specialised suppliers. Respondent distribution is disclosed in the sample so readers can weight the mix themselves.
-
Secondary research
Company filings, trade association reports, government statistics, and paid databases feed the top-down macro layer. Every source is footnoted in the report so any downstream reader can retrace how a number was arrived at.
-
Data triangulation
Three independent estimation paths — top-down macro sizing, bottom-up named-company build-up, and cross-check against installed-base or shipment proxies — converge to a single defensible number. Divergences greater than 8% trigger a re-review.
-
Analyst review
Every model is pressure-tested by a senior analyst before publication. Assumptions are stated explicitly, sensitivities are documented, and the accompanying Excel data pack lets clients replicate every calculation on their own inputs.

The growing popularity of hybrid and electric vehicles, which rely on EHR systems to boost the performance of their internal combustion engines and increase the range of their electric powertrains, is another factor driving the industry. -
• What are the leading applications in this market?
Using the waste heat energy from a car's exhaust system to heat the cabin or passenger area is known as an Automotive Exhaust Heat Recovery (EHR) System. It is possible to achieve this by putting the exhaust gases via a heat exchanger, where they give off heat to a fluid (such as coolant or air) that is then utilized to heat the cabin. An EHR engine cooling system can be utilized in conjunction with other cooling systems, such as conventional air or liquid cooling, and can be integrated into the car's existing exhaust system. It works by heating coolant or air that is then circulated through the engine to provide cooling using heat from the exhaust gases that would otherwise be wasted. To use the waste heat energy from a car's exhaust system to create electricity is called an Automotive Exhaust Heat Recovery (EHR) System. This can be accomplished by transferring the exhaust gases through a heat exchanger, where they give off heat to an air or coolant-filled fluid. Following that, the heated fluid is utilized to power a generator, which generates electricity that can either be used to power the vehicle's systems or stored in a battery for later use. -
