This constant R&D in tappet design promises compatibility with changing powertrains, boosting the progress of the automotive tappets market.

Restraints

Volatility in the prices of raw materials hampers the market progress

Automotive tappets primarily depend on alloy, steel, and other specialty materials, whose prices have been highly volatile. According to research, worldwide steel prices increased by 15% in the first half of 2024 due to supply chain disruptions and geopolitical tensions. These variations raise manufacturing costs and decrease profit margins for tappet producers. In recent news, many component producers in North America and Europe have temporarily slowed production due to significant increases in alloy costs, which are adversely impacting tappet supply. This raw material dependency restricts consistent scaling and impacts industry stability.

Opportunities

How does the adoption of lightweight materials present favorable prospects for the expansion of the automotive tappets market?

Automakers are moving towards lightweight engines to enhance fuel efficiency, motivating the use of alloy and aluminum tappets. According to the 2024 research, lightweight components can reduce engine weight by 5-10%, improving performance. Tappet manufacturers who advance in material science can gain a competitive advantage. Recent news from Schaeffler AG highlights tappet prototypes designed for hybrid engines. This material advancement offers a fresh market niche with substantial growth potential, positively impacting the automotive tappets industry.

Challenges

Technological complexity and R&D costs limit the market growth

Developing tappets for high-performance, GDI, and hybrid engines requires advanced research and development, as well as precision manufacturing. According to the 2024 reports, research and development costs for novel tappet designs can exceed USD 2-3 million per engine platform. High technical complexity raises testing cycles and failure risks. Recent delays reported by Bosch and Mahle in the introduction of tappet products highlight this intricacy. Companies should strike a balance between innovation and production feasibility to remain competitive.
