In Summary… • “Linear” change will define certain aspects of the
future
• Advances in technology are a certainty – today’s trends in technology make the future visible
• Globalization in emissions regulation will be a driving force for real efficiency progress – if done correctly
• Freight efficiency improvements require not only engine advancements but also powertrain improvement, vehicle improvements and optimized system integration
• Exciting times continue for the commercial vehicle industry
• YOU are at the front line of technology development Our engineers are the ‘engine’ that will propel us into the future of commercial vehicles
