(MAHLE) At IAA Mobility, MAHLE is presenting innovations for electrification and further sustainable powertrain solutions; New range extender system and thermal management module extend the range of electric vehicles and relieve customers’ range anxiety; MAHLE supplies components for efficient ethanol engines which help in leveraging the tremendous potential of biofuels for climate protection immediately and effectively; Technological diversity is and remains the strategic approach of the globally active group; MAHLE CEO Franz: “Europe needs technological diversity for climate protection, to strengthen its competitiveness and to safeguard employment in Europe.”
At this year’s IAA Mobility in Munich, MAHLE is presenting innovations for electrification and further sustainable powertrain solutions to reduce CO2 emissions in road traffic. “Our products are not just visions. They are ready for series production and offer genuine solutions to genuine challenges faced by our customers,” said Arnd Franz, Chairman of the MAHLE Management Board and CEO, speaking to an audience of journalists at the IAA. He added that MAHLE’s highly efficient new range extender system with its high-voltage generator could extend the range of battery-electric vehicles to as much as 1,350 km, making it the “motor of e-mobility”. A compact thermal management module with integrated heat pump can extend the range of electric vehicles by up to 20 percent even at low temperatures.
In addition, MAHLE is showcasing components for internal combustion engines that can be operated on up to 100% ethanol, massively and immediately reducing the carbon dioxide emissions of the existing vehicle pool. “MAHLE is doing its homework and working on the decarbonization of road traffic in all areas of technology. Europe must now follow the other major world markets and allow competition between all technologies in its CO2 regulation,” said the CEO. “This is not just a matter of climate protection but also of Europe’s competitiveness and safeguarding employment.” IAA Mobility is being held from September 9 to 14, 2025. The MAHLE stand is in Hall A1.
“Efficiency in Motion” is the mission of the MAHLE Group. Under the heading of “Efficiency3”, the company is presenting at the international motor show innovations from its three strategic areas of electrification, thermal management and sustainable internal combustion engines. “Our customers expect quality, reliability, a good price-performance ratio, and efficiency,” said Arnd Franz. “And that is what MAHLE delivers.”
Range extender system – the motor of e-mobility: compact, resource-conserving drive package
In addition to pure battery-electric vehicles, MAHLE’s strategy is based on range extender technology to boost acceptance of e-mobility by relieving customers’ range anxiety. It is forecast that the market for electric vehicles with range extenders will grow by 15 percent per year up to 2030; strong demand is already evident, especially in China. The new system from MAHLE allows the cost-effective right-sizing of the battery and reduces charging times on longer trips.

- Can be used immediately on the existing vehicle fleet without any compromises in terms of performance or reliability
Bionic radial blower: penguin makes for efficiency
With a view to further improving the efficiency of its products, MAHLE has repeatedly been inspired by nature. The most recent example is a revolutionary bionic radial blower for vehicle air conditioning systems. In this case, the development engineers at MAHLE took their inspiration for the design of the blower blades from penguins’ flippers. They were supported by an in-house AI tool. MAHLE refers to the process of engineers guiding AI and providing data as “superhuman engineering”. This approach allowed more than 30 million virtual designs to be generated within a very short space of time and the first prototypes were rapidly produced. The innovative blower can be used in a wide range of passenger cars and commercial vehicles and sets new standards for the sector.
System benefits through optimized design:
- 4 decibels quieter (-60 percent) than conventional components
- 15 percent higher energy efficiency
- The compact, symmetrical design of the air conditioning unit creates more space for other components, a key advantage especially for battery-electric vehicles.
MAHLE is also presenting solutions for smart charging on its stand. MAHLE chargeBIG has become an established player for professional, scalable cable-connected charging infrastructure. Several thousand charging points have already been installed in Germany and France. Since the summer of 2025, the latest product generation has been available. This makes the electrification of customer parking spaces even easier. chargeBIG includes the smallest wallbox in the world. It now also offers a mobile solution that can be used immediately on construction sites and at events without complex installation work.
MAHLE’s inductive charging system paves the way for the rapid, area-wide introduction of this attractive alternative to cable-connected charging. The convenient positioning system offered by MAHLE, which has been recognized as a global standard by American standardization Institute SAE International, ensures that the vehicle is aligned in the optimum position above the infrastructure unit, maximizing the efficiency of energy transmission – over 92 percent are possible under everyday conditions.
At IAA Mobility, MAHLE is showcasing products for the targeted, fast and efficient maintenance of electric vehicles including its E-HEALTH Charge battery diagnostics unit. This unit can measure the performance of the high-voltage battery in an electric vehicle within only 15 minutes.
In the test drive area of the show, visitors can see for themselves how MAHLE controls and trains the air conditioning system of a vehicle individually for each occupant using artificial intelligence and takes active cabin air purification to a new quality level.
Also in the test drive area, visitors can view the MAHLE Workshop Heroes Van.
