Stuttgart/Germany, January 31, 2018 – As of February 1, the new CEO of MAHLE, the fourth-largest German automotive supplier with sales of around EUR 13 billion and 77,000 employees, will be Dr. Jörg Stratmann. When ZF Friedrichshafen AG and Wolf-Henning Scheider, Chairman of the MAHLE Management Board until the end of January, both expressed the desire for a change, the MAHLE Group was able to resolve the matter swiftly.

  • The 48-year-old industrial engineer becomes the new CEO of the MAHLE Group as of February 1, 2018.
  • Wolf-Henning Scheider leaves MAHLE on January 31, 2018.
  • Succession arrangements and new appointments at the top-level management of the MAHLE Group implemented quickly and sustainably.

This quick transition was made much easier because MAHLE had already earmarked Dr. Jörg Stratmann as a possible successor. Dr. Stratmann joined the MAHLE Group after leaving Continental AG in 2008 and has taken on increasingly demanding tasks. Until now, he has been responsible for managing the entire MAHLE Behr Group, now the MAHLE Thermal Management business unit, which comprises a number of operational units and most recently accounted for over 45 percent of MAHLE’s group sales with its future-oriented products.

“Dr. Stratmann brings a wealth of automotive experience—from both a technical and a business perspective. He is the ideal person to head the MAHLE Group,” stated Chairman of the MAHLE Supervisory Board, Prof. Dr. Heinz K. Junker.

Following in his footsteps is Bernd Eckl (50), who since April 1, 2017, has been a Member of the MAHLE Management Board with responsibility for the Engine Systems and Components business unit, which generates around 22 percent of MAHLE’s group sales. Bernd Eckl joined MAHLE from Getrag at the start of 2017 and rapidly made an outstanding contribution with his excellent teamwork within the MAHLE Management Board.

Georg Dietz (54) has been appointed a Member of the MAHLE Management Board for the Engine Systems and Components business unit. He has worked at MAHLE for 28 years and has demonstrated his technical and international competence in a wide variety of roles and with long deployments abroad.

MAHLE would like to wish the departing Chairman of the MAHLE Management Board, Wolf-Henning Scheider, who steps down on January 31, 2018, all the best and much success in his future role. “Our thanks go to Mr. Scheider above all for his intensive work during the transformation process that is currently affecting the whole automotive industry,” commented Prof. Junker.

“I firmly believe that with these personnel changes and new appointments we have made the right choices to guarantee a sustainable setup within the top level of management at the MAHLE Group. It is particularly important to me that we further focus on the ongoing technological development of MAHLE’s product portfolio. With the top management team at the head of the group, we are sure to succeed. I would particularly like to thank all shareholders and the members of the group’s boards and committees, including those on the employee side, of course, who have helped us to make these time-critical decisions with the necessary urgency. Without this intensive cooperation at all levels, such a prompt solution would not have been possible,” added Prof. Junker.

Tata Motors and MAHLE partnered to develop Secondary Loop Mobile AC System (SL-MAC)

Secondary Loop Mobile Air Conditioning System
A secondary refrigerant used in a secondary loop

13 July 2017– Tata Motors Limited and MAHLE, one of the world’s 20 largest suppliers to the automotive industry, have signed a joint development agreement for designing and developing a Secondary Loop Mobile Air Conditioning System (SL–MAC), under the aegis of United Nations Environment. MAHLE and Tata Motors, along with the Institute for Governance and Sustainable Development (IGSD), which is coordinating the project, received funding for developing the SL-MAC system from the Climate and Clean Air Coalition to Reduce Short-Lived Climate Pollutants (CCAC), a global initiative to support fast action and make a difference in the areas of climate, public health, and food and energy security. This project envisages use and trial of environment friendly, low global warming potential (GWP) refrigerants HF01234yf (ASHRAE A2L) and HFC-152a (ASHRAE A2).

A team comprising of representatives of the California Air Resources Board (CARB), the Mobile Air Conditioning Society Worldwide (MACS), the National Renewable Energy Lab (NREL), MAHLE, Tata Motors, and IGSD reviewed the newly constructed SL-MAC system and the prototype at the MAHLE Behr facility in Lockport, New York, USA, on 7 April 2017.

A Tata vehicle based on a new generation platform for utility vehicles, consisting of a more complex architecture with front and rear air conditioning system, has been selected for this joint development program. The SL–MAC system will first be installed in the Tata utility vehicle as a prototype. In the SL-MAC system, the alternative refrigerants first cool a secondary fluid/coolant, which in turn cools the air to comfortable temperatures inside the vehicle cabin. This process allows the safe use of slightly flammable refrigerants that have a low GWP and in turn achieves high cooling capacity, minimizing the losses and achieving an optimized overall thermodynamic efficiency in the process. This is in contrast to the conventional mobile AC system, where the cabin air is directly cooled by the refrigerant HFC-134a, which is ozone safe but has a high GWP.

According to Dr. Tim Leverton, Chief Technology Officer, Tata Motors – “Tata Motors has been at the forefront of innovation and is constantly working towards shaping the future of mobility. As a part of our R &D efforts, we are committed to pioneering and inventing solutions to a greener future in the auto industry and this initiative is a step in that direction. We are the first OEM in India who is developing and evaluating an SL-MAC system on a car, using environmentally friendly refrigerants. We are delighted to work with class leading global suppliers like MAHLE and institutions like IGSD to contribute to the United Nations Environment initiative.”

The new SL-MAC system, which is testing the low-GWP refrigerants, is expected to increase vehicle energy efficiency through engineering. This system will turn off the compressor during acceleration and will retain coolness when the compressor is inactive or the engine is turned off for a short duration, allowing rapid cool-down at re-start. In addition to the expected energy efficiency benefits (fuel saving of up to 3%), the SL-MAC system allows the use of refrigerants that should avoid flow into the vehicle cabin. The refrigerant never enters the passenger compartment and instead stays in the engine area. Only the coolant circulates through the interior air conditioning unit.

According to Dr. Stephen O. Andersen, PhD, Director of Research for IGSD – “The Secondary Loop System will permit the use of alternative refrigerants like HFC-152a (GWP of 138) and HFO-1234yf (GWP<1) which have much lower GWPs than the current most-commonly used refrigerant, HFC-134a (GWP of 1300). We will be comparing the life-cycle carbon footprint of HFC-152a – with a higher GWP offset by higher energy efficiency – to the carbon footprint of HFO-1234yf and we will be estimating the cost of manufacture and ownership for each system.”

The SL-MAC project is on schedule, as expected, with anticipated environmental and cost advantages to be determined in the next stages. The prototype will be tested on the Indian roads later in the third quarter of 2017, where long seasons of hot and humid weather and stop-start driving conditions make a secondary loop air conditioning system highly advantageous.
