-SCT (Superior Continuous Torque) motors can provide 93% of peak output power continuously. -Cooling is provided by passing air and oil through a hollow shaft and agitating it as the rotor rotates. Features less loss than a fully oil-cooled system.
- Bionic designed radial fan for HVAC. Shape optimization by AI based on the shape of penguin feathers. Achieves 15% higher efficiency and 3.9dB lower noise compared to conventional fans.
-Heat exchanger for coolant used to cool EV batteries, e-Axles, etc. and refrigerant used on the HVAC side. Combining everything into one module makes it compact, and it also features a heat pump, which helps reduce energy consumption for heating.
- Cooling plate for battery packs. Tuning was performed through repeated simulations to minimize flow path resistance. Cooling efficiency is optimized by designing the flow path with varying flow velocities in the front and back halves. This reduces pressure drop by up to 20% and increases heat transfer by 10%.

MAHLE hydrogen power cell unit (PCU) 2025 JSAE Automotive Engineering Exposition MAHLE GmbH
-Pistons for hydrogen engines. -To suppress abnormal combustion, which is an issue in hydrogen engines, oil intrusion into the combustion chamber is minimized, and hydrogen leakage (blow-by) into the crankcase is also suppressed. -Mass production will begin in 2025 for MAN's hydrogen engine trucks.
- The product achieves the high precision, low contamination, and multi-specification surface treatment required for fuel cell components. In addition, the weight is reduced by using PPS molding instead of aluminum casting.
