Propulsion Type Insights

Internal Combustion Engine (ICE) vehicles led the global automotive electronic control unit (ECU) market with significant revenue share proportion in the year 2024, accounting for nearly 96%. Further, the segment expected to dominate the overall automotive ECU market during the forecast period. This is majorly attributed to the rising production of ICE vehicles across developing countries especially in China and India. However, the segment projected to exhibit minimal growth rate over the analysis period due to increasing penetration of electric and hybrid vehicles.

Hybrid vehicles anticipated to flourish prominently with remarkable CAGR over the forecast period owing to low carbon emission, enhanced fuel efficiency, and extended driving range. On the contrary, battery-powered vehicle encountered the fastest growth in the coming years. The segment growth is mainly because of the increasing government initiatives to control pollution along with rising consumer awareness for energy-efficient vehicles.

• In July 2024, Toyota unveiled a new and in-development internal combustion engine (ICE) that the company itself calls a “game-changer". These 1.5-litre and 2.0-litre four-cylinder engines are designed to be much more efficient than current offerings.
