What s driving Regulations electrification? OE technology choices Consumer preference Manufacturers forced to pursue new technologies to meet requirements Regional test methods and enforcement vary Regional trends are similar Powertrain - Turbo / downsizing - Fuel delivery / valve control - Transmission Chassis - Aerodynamics - Tires - Mass reduction Electrification - Smart Charging - Start-Stop - Micro Hybrid - xev Consumers focused on basic needs first - Once basic needs are met, purchase decision is largely economic Segment differentiators - Price - Brand - Configuration - MPG - Years on market Willing to pay for fuel economy improvement Acceptance of new powertrains - Looks weird - Slow Acceleration 3 Johnson Controls 2014 High Impact on Battery Systems Regional regulatory differences have an impact on the benefit of various electrification options 3
