Cylinder Deactivation System Market Report 2026

The cylinder deactivation system market size has grown strongly in recent years. It will grow from $3.86 billion in 2025 to $4.06 billion in 2026 at a compound annual growth rate (CAGR) of 5.1%. The growth in the historic period can be attributed to emission regulation enforcement, demand for fuel-efficient vehicles, internal combustion engine optimization, automotive technology evolution, OEM adoption of efficiency systems.

The cylinder deactivation system market size is expected to see steady growth in the next few years. It will grow to $4.88 billion in 2030 at a compound annual growth rate (CAGR) of 4.7%. The growth in the forecast period can be attributed to stricter emission norms, hybrid vehicle growth, advanced engine management systems, real-time engine monitoring, sustainability-driven vehicle design. Major trends in the forecast period include integration with engine downsizing strategies, adoption in high-end vehicles, expansion of smart engine controls, focus on fuel economy improvement, compatibility with hybrid powertrains.

The increasing vehicle production is expected to propel the growth of the cylinder deactivation system going forward. Vehicle production is a complex, multi-faceted process that involves numerous industries and technologies, requiring coordination and precision to ensure the production of reliable and safe vehicles. The demand for vehicles is due to economic growth and urbanization, increasing globalization and market expansion, infrastructure development, and cultural and social influences. Cylinder deactivation systems are integrated into vehicle production to enhance fuel efficiency and reduce emissions by integrating cylinder deactivation systems into vehicle production, manufacturers create engines that deliver better fuel efficiency and lower emissions without compromising power and performance when needed. For instance, in May 2023, according to the Global Association of European Automobile Manufactures (ACEA), a Belgium-based government organization, around 85.4 million vehicles were produced worldwide, an increase of 3% compared to 2024. Therefore, rising vehicle production drives the cylinder deactivation system market.

The increasing adoption of hybrid electric vehicles is expected to propel the growth of the cylinder deactivation system going forward. A hybrid electric vehicle (HEV) is a car that uses both an internal combustion engine and an electric motor to improve fuel efficiency and reduce emissions. Hybrid electric vehicles are rising due to growing demand for better fuel efficiency and lower emissions compared to conventional gasoline vehicles. Cylinder deactivation systems in hybrid electric vehicles shut down selected engine cylinders during low-load conditions to reduce fuel consumption and improve overall efficiency. For instance, in August 2024, according to the Energy Information Administration (EIA), a US-based government agency, reported that hybrid vehicles made up 8.6% of all light-duty vehicle sales in the first quarter of 2024, rising to 9.6% in the second quarter of the year. Therefore, increasing adoption of hybrid electric vehicles is driving the growth of the cylinder deactivation system market.

Major companies operating in the cylinder deactivation system market are focusing on adapting cylinder deactivation (CDA) technology for heavy-duty diesel engines, such as modular variable valve actuation CDA, to gain a competitive advantage. For instance, in July 2024, Cummins Valvetrain Technologies, a US-based technology company, announced the latest on-road evaluations of its Jacobs Cylinder Deactivation (CDA) technology, confirming measurable fuel-efficiency and emissions benefits for heavy-duty trucks. In standardized SAE J1321 tests, CDA delivered a 2.76% fuel-saving on highway routes and 2% on distribution routes using fully loaded comparison vehicles. The system improves efficiency by shutting down select cylinders under low-load conditions, reducing parasitic losses and maintaining higher exhaust temperatures for better after-treatment performance. CDA also enhances braking through integration with the Jake Brake® system. Designed to support tightening EPA 27 and Euro 7 regulations, the technology is currently progressing across multiple engine development programs.
