1 MAHLE 17th Stuttgart Entwicklungen International für Symposium den Antrieb von heute und morgen MAHLE Products and Systems Driving Today's and Tomorrow's Powertrain 1 17th Stuttgart International Symposium March 2017 Wolf-Henning Scheider CEO of the MAHLE Group

2 Trends and Challenges in a Changing Mobility World DIGITAL TECHNOLOGY New Mobility Concepts Connected Car Local Pollutants Autonomous Driving Green House Gases Multiple / CO 2 factors influencing modern vehicle development EMISSIONS 2

3 The Solution? Zero Emission? Electric vehicles with zero local emissions 3

4 What is the CO 2 footprint of electric energy? It depends on the energy mix and the time of charging! 100% Renewables 90% 28 % 43 80% Nuclear % 70% vs. Gas Oil 60% 50% 40% 30% Day Night Solids 20% 10% vs. EU power generation by fuel [Source: Publication European Commission 2016] Wind Calm CO 2 footprint of electric energy depends on several factors 4

5 MAHLE Future Worlds (Base and Extreme Scenarios) Powertrain mix Well-to-wheel Green zones Green planet Statutory regulations 1 Base Scenario CHIndia Asian growth Localization Price aggressive suppliers 2 Autonomous driving Car sharing Connected cars LV volume reduction Mr. Roboto Automotive mega suppliers Margin pressure Built to print Increased Tier 2 business New Order High degree of uncertainty leads to various future scenarios 5

6 Dual Strategy HVAC Highly efficient combustion engines Emerging markets New projects Thermal management Commercial vehicles & Off-Highway Aftermarket Electric drives Electric auxiliaries Dual Strategy to consequently further develop ICEs and electric drives at the same time 6
