Conventional mobility reaches its limits Key challenges Rising CO 2 emissions threaten the global climate and the environment - Without appropriate countermeasures, global CO 2 emissions will double by 2050 Increasing mobility demands are driven by population growth and a growing middle class, especially in BRIC* countries Finite resources such as fossil fuels will run out inevitably Consumer needs concerning mobility are changing The future of mobility must be green 14 Source: International Energy Agency * BRIC countries: Brazil, Russia, India, China

Drivers for Green Mobility Environmental challenges Urbanization Growing population and middle class Changing consumer demands Economic challenges Politics 15

Growing population and middle class inevitably result in even higher mobility Growing world population In 2050, the world population is expected to reach 9.3 billion people Growing middle class in BRIC In 2020, an additional 800 million people will achieve middle class status in BRIC countries* By 2050, all modes of mobility in emerging countries (including BRIC) will have experienced considerable growth** Cars / light-trucks: 5.7x increase Two-wheelers: 3.8x increase Rail: 3.0x increase Aircraft: 2.5x increase Bus: 1.3x increase Main challenge: enabling continuous but sustainable growth 16 Sources: OECD Transport Outlook 2012; UN Population Division * Income bracket of >US$ 6,000 and < US$ 30,000 per capita in BRIC countries ** Changes in passenger mobility compared to 2010

Environmentally friendly means of transport make an important contribution to Green Mobility Means of transport Infrastructure / urban planning Energy Information management systems The future belongs to modern forms of transport offering improved energy efficiency and minimal CO 2 emissions, e.g. due to - Green Tires - Innovative drivetrains - Aerodynamic improvements - Electronic assistance systems - Lightweight design 24

Especially cars have the potential to be significantly improved Cars have the highest operating costs of all means of transport Negative environmental impact of cars due to - High CO 2 emissions per person transported - Relatively short distance driven per 1 ton CO 2 emission ** Operating cost per 100 km* EUR 26.00 EUR 11.30 EUR 9.90 EUR 8.60 Average CO 2 emissions per person 380 g/km 150 g/km Industry must find ways to make cars greener ** 40 g/km 20 g/km 25 Source: Green Mobility Maßnahmen zur Verringerung von CO 2 -Emmissionen im Vergleich (Green mobility a comparison of measures for reducing CO 2 emissions) by Prof. Dr. Horst Wildemann, Munich Technical University * Figures assume that long-distance buses and trains run at 44% average capacity; airplanes at 73% capacity, and cars carry 1.5 persons; operating costs for a car carrying 3 persons equal EUR 11.30 ** Long-distance buses

The requirements for modern cars are expanding and with them, vehicle weight There are 900 million cars across the world a number that is set to more than double by 2050 The result is that cars need to become both more economical and more ecological Additionally, customer requirements are on the rise: - Higher safety standards (e.g. ABS, Airbags, reinforced car body structure) - Greater comfort and quality (e.g. airconditioning, audoio, satnav, and parking systems) - High-quality design The consequence is a trend towards greater weight The car is changing as requirements expand Reliability Affordability Safety Fuel consumption Factors behind the increase in weight Sustainability Connectivity?????? 1886 2012 2016 2036 Over the last 40 years cars have continuously got heavier Legislation Safety Interior 25% 30% 15% 22% 8% Example: Mini Cooper Comfort Quality 26 Sources: Valeo; Klimacampus; Automotive Now (1/2011) - KPMG International; VW; BMW

New drive concepts also adversely affect a car s weight Emission-reduction measures based on innovative drive systems increase weight In the long run alternative energy sources will replace fossil fuels for car engines??? Electric vehicle Range extender Electric vehicle with an internal combustion engine to charge the battery The result: increased system costs*, impaired handling, and reduced range Alternative drive systems need to be compensated for cars must be made lighter Optimized combustion engine Partial hybrid Full hybrid Plug-in hybrid Electric jump start, electric driving at a low speed Start-stop systems, regenerative brakes Full hybrid with a large battery and plug-in capability 27 Sources: Lightweight, heavy impact by McKinsey, Elektromobilität Anforderungen an Reifen, Fahrwerk, Antrieb und Marktpotenziale (Electric vehicles demands on tyres, chassis, drive, and market potential) by Prof. Dr. Horst Wildemann, Munich Technical University * Because, among other things, batteries and brake/insulation systems need to be larger

Lightweight design a key technology for sustainable mobility Lighter cars increase fuel efficiency, reduce CO 2 emissions in road traffic, thereby contributing to Greener Mobility Increasing demands for comfort and safety cause the weight to spiral upwards lightweight design ensures that cars remain economical Lightweight design compensates for the negative consequences of new drive concepts (e.g. battery in electric cars) without lightweight design modern mobility is unthinkable 28

Even a savings of 100 kg enables enormous emission reductions Driving resistance considerably influences vehicles fuel consumption and CO 2 emissions - The higher the resistance, the more energy is required to move the vehicle Rolling, gradient, and acceleration resistances are highly dependent on the vehicle weight and are thus directly influenced by lightweight design Lightweight design is therefore suitable as an effective means of reducing CO 2 emissions and fuel consumption Mass is a key factor in determining the resistances that act on a vehicle lightweight design is the logical solution Acceleration resistance mass x acceleration of the vehicle Rolling resistance (mass x gravity) x rolling friction * c w value: air-resistance coefficient Air resistance (air density/2) x c w * x vehicle surface x speed 2 Gradient resistance (mass x gravity) x (gradient height/gradient length) Rule of thumb: 100 kg less weight means savings of 0.5 l fuel per 100 km and 11.65 g less CO 2 per kilometer travelled** 29 Source: Green Mobility Maßnahmen zur Verringerung von CO 2 -Emmissionen im Vergleich (Green mobility a comparison of measures for reducing CO 2 emissions) by Prof. Dr. Horst Wildemann, Munich Technical University ** Based on a car weighing 1,400 kg and an average consumption of 8 l of conventional fuel per 100 km, which corresponds to an output of 2.33 kg of CO 2 per liter (basis of comparison: car with a life cycle of 120,000 km in six years)

Lightweight design is an effective way to optimize e-mobility concepts Lightweight design increases the range of electric cars The drivetrain of a battery-driven electric car is considerably heavier than the drivetrain of a car with an internal combustion engine Weight is the key factor for e-cars range To increase the range you can either use bigger, more expensive batteries or reduce the vehicle weight The use of lightweight design compensates for battery weight and thereby increases the range Even at costs of up to EUR 14.50 per kg* lightweight solutions are still more cost-effective than larger batteries Lightweight design plays a central role in the widespread use of e-mobility Battery range required by consumers in Germany in 2009 (in km) The average range is currently just 135 km 30 Source: Elektromobilität Anforderungen an Reifen, Fahrwerk, Antrieb und Marktpotenziale (Electric vehicles demands on tires, chassis, drive, and market potential) by Prof. Dr. Horst Wildemann, Munich Technical University * Based on the battery price in 2011

Vehicle weight can be reduced in various ways Areas where lightweight design can be applied: (Share of weight of the vehicle components in %) Lightweight construction methods and lightweight materials can significantly reduce vehicle weight and thus the driving resistance* Interior Electronics Car body Lightweight design Drivetrain Chassis Lightweight construction methods Lightweight materials 31 * Weight savings can also be made by omitting components or downsizing. However, such measures are often not in line with customer expectations and may result in marketing challenges

Lightweight construction methods comprehensive lightweight construction of all vehicle parts Less weight through a combination of lightweight components and innovative concepts For example, various technologies have been developed in the area of the car body: - Multi-material construction: the optimal material is used for each part - Hybrid construction: usually a combination of steel and aluminum - Spaceframe construction: use of extruded metal sections that enclose the passenger compartment However, it is only possible to reduce weight substantially if lightweight construction methods are used throughout the car Successful lightweight construction uses new technologies through the whole car 32 Source: Green Mobility - Maßnahmen zur Verringerung von CO 2 -Emmissionen im Vergleich (Green mobility a comparison of measures for reducing CO 2 emissions) by Prof. Dr. Horst Wildemann, Munich Technical University

Saving weight through smart material combinations, such as plastic/metal hybrid technology Plastic/metal hybrid technology* permits more functions to be integrated into car parts Combining the properties of both materials creates a higher performance than either can achieve separately - Metals such as steel and aluminum provide high strength and stiffness - High-tech plastics such as glass-fiber-reinforced polyamide improve the components properties and allow a reduction in wall thicknesses Significant benefits (in comparison with 100% steel components) Weight reduction of up to 50% High functional integration in the injection molding process reduces the number of process steps, enabling costs to be cut by up to 40% Greater precision, quality, and strength Already successfully applied in practice numerous times Hybrid technology is used in many car components Pedal system Front end Roof frame Structural inserts 33 * Hybrid technology developed by LANXESS

Design with lightweight materials lighter materials that satisfy all requirements Choosing lighter materials aims to reduce the weight of the car Depending on where it is used, the requirements for a vehicle component and thus the material it is made of vary greatly - For example, materials in the engine compartment must be particularly heatstable In the interior, aesthetic considerations are relevant as well as weight The right material needs to be used for the right application 34
