Automotive engineering, electrification, and thermal management are evolving as manufacturers balance efficiency, emissions, and performance across diverse powertrain architectures. In this context, Marelli is presenting a portfolio of propulsion and thermal innovations at Auto China 2026 (Beijing, China, 24 April–3 May 2026, Booth W2B08, Hall W2, NCIEC), highlighting solutions designed to support both conventional and electrified vehicle platforms.
The technologies address key challenges in modern vehicle development, including energy efficiency, thermal optimization, and flexibility across different propulsion systems.
Modular cooling solutions for electrified transmissions
A central highlight is the new e-Transmission Cooling Pump, designed to deliver on-demand oil cooling for e-axles and dedicated hybrid transmissions (DHT). The system is based on a modular architecture with integrated electronics and brushless motor technology.
Key technical characteristics include:
- Energy efficiency: Approximately 30 W lower consumption compared to typical market benchmarks
- High system efficiency: Around 40% efficiency for transmission control applications
- Multi-voltage compatibility: Available in 12 V and 48 V configurations
- Modular design: Adaptable for multiple transmission-related applications
The solution improves thermal control and contributes to both electric driving range and fuel efficiency in hybrid systems.
Flex fuel technology for diverse propulsion strategies
To support internal combustion and hybrid powertrains, Marelli is also presenting its flex fuel system, designed for 3- and 4-cylinder engines. The system enables the use of biofuels and ethanol while maintaining performance and emissions control.
Functional features include:
