The automotive heat shields market reached $11.8 billion in 2020 and is expected to expand 3.5% from 2023 to 2030. Electric vehicles, lightweight and fuel-efficient passenger cars, and commercial vehicles will drive market growth. The heat shield helps maintain thermal comfort within the automobile, protects delicate vehicle components from heat, and dissipates excess vehicle heat. The gadget also boosts engine power by decreasing hood and intake air temperatures. If the vehicle creates too much heat and lacks proper heat management, it may not perform properly. An overheated engine may lose power and spark plugs. To manage vehicle temperatures and maximise fuel efficiency, utilise efficient heat shields. Electric vehicles using lithium-ion batteries create a lot of heat. Lack of heat management and dissipation affects battery life and vehicle range. Growing interest in electric vehicles is expected to drive product demand throughout the forecast timeframe.

Increasing fuel economy standards in the EU, Japan, and China have prompted OEMs to emphasise lightweighting and engine efficiency. The European Commission introduced fuel-efficiency measures in December 2018. By 2025, average CO2 emissions from vehicles and vans were expected to be 15% lower, and by 2030, 37.5% lower. The authority aims to cut LCV emissions by 15% by 2025 and 31% by 2030. Lightweight heat shields would reduce the car's weight and fuel efficiency. Leading OEMs are developing lightweight technologies to meet stricter fuel efficiency rules. Heat shield producers focus on lightweight, effective solutions. Tenneco, the heat shield industry leader, offers an ultra-lightweight corrugated aluminium heat shield. It improves thermal protection by 15–30% over aluminized steel while being 80% lighter. Comparing aluminized steel heat shields. It can be used in the catalytic converter, exhaust manifold, and turbocharger to boost fuel efficiency. As OEMs develop more fuel-efficient cars, heat shield companies make similar advances. Lightweighting and fuel economy will increase need for better heat shields in future cars.

The automotive components industry has always been regulated, and businesses must follow a variety of rules. Such legislation in the automotive sector force OEMs to produce products that comply with regulations. These regulations require reduced carbon emissions from vehicles, so manufacturers are reducing the number of cylinders to reduce engine size. To maintain engine power, a turbocharger or supercharger is fitted. This device needs a heat shield to avoid overheating. Growing use of turbochargers in spark ignition and compression ignition engines is expected to boost heat shield use. Law requires turbochargers to have heat shields.

24 major European nations enacted new car taxes in April 2020 based on fuel use or CO2 emissions. European automakers are moving to electric or mild hybrid automobiles. Instead of improving ICE vehicles to meet regulations, OEMs are investing in electric propulsion. EV heat shields would generate new economic opportunities, although thermal management is less important in EVs than in ICE vehicles. Existing ICE heat shields won't work. Heat shield manufacturers must devote more resources to research, design, and development for electric vehicles (EVs). If the government limits ICE automobiles and pushes alternative energies, heat shield demand will be lower in the future.

The auto industry has long been subject to government restrictions, which require stringent adherence to norms. OEMs are pressured to design compliant devices. To cut carbon emissions, laws call for smaller engines and fewer cylinders. Turbochargers or superchargers boost engine power. Turbochargers have heat shields for optimum functioning. As turbochargers and compression engines become more popular, the demand for automobile heat shields is projected to rise.As environmental concerns grow worldwide, governments are working to adopt stricter standards to reduce the noise, vibration, and harshness (NVH) caused by light and heavy vehicles. OEMs and Tier I businesses are developing effective soundproofing barriers for under a car's hood, which will raise demand for under-hood heat shields.

Single shell heat shields accounted for almost 60% of overall revenue in 2021. A single shell product is 0.3 to 1.0 mm thick and constructed of aluminium foil. This heat barrier works well against moderately hot sources. The increased area requirement may hinder its adoption during the forecast term.Double-shell heat shields are commonly made from 0.3 to 1.0 mm thick aluminium sheets. These goods have a low thermal expansion coefficient and can operate in cold to room temperature. This substance is used to regulate heat in catalytic converters, turbochargers, and starter motors.

The engine compartment segment accounted for more than 30% of overall revenue in 2021. Heat shields are used to protect engine assemblies from high temperatures. The car's engine is its most important part. Improper heat management can cause the engine to fail, shortening its life.Regulatory agencies throughout the world are tightening automobile pollution rules to slow environmental damage. The trend will likely raise demand for car turbochargers because they are environmentally friendly and help drivers achieve better fuel economy. This drives product demand.Turbocharger applications are expected to grow at the greatest CAGR of 4.8% over the forecast period. The growing use of turbochargers in passenger cars, light commercial vehicles, and heavy commercial vehicles is expected to promote market growth in the near future.Heat regulation improves a vehicle's performance, fuel efficiency, and service life.
