Mercedes-Benz: A Greener Luxury Sedan Stephanie Dalquist Seward Matwick Bill Nickerson 13 May 2002
Mercedes-Benz Strategy Manufacture world-class luxury cars Maintain industry leadership in technology and design Maximize profits, delivering consumer and environmental benefits “Resource management” value system –Free market: get the prices right –Earth as a closed system –Technology is the answer: improved efficiency, recyclability
Motivations for Change Maintain profitability Meet environmental mandates –Recycling laws –Fuel efficiency Balance the competing mandates while still achieving profitability
Impact on Design Goals Profitability first –A corporation, above all Deliberate material selection –Aim to meet new EU mandates –Improve fuel efficiency –Provide return on perceived customer value EPS to confirm design choices
The New Mercedes-Benz: Materials Aluminum Roof Steel QPI SMC QPO SMC Floor Production 50,000 BIW Cost $ % recyclable 22.9 mpg
Advantages of the New Mercedes-Benz Increased profit margin, savings on BIW Meet EU recycling mandate Lighter total weight –Greater fuel economy –Lower emissions
Base Case Comparison New ModelChange Cost$1996-$353 Weight2748 lbs lbs Recyclability81%+6.3% ELI Fuel efficiency22.8 MPG+1.3 MPG
Change in BIW Profit by Case Number
Cost Savings versus Recyclability
Cost Savings versus Fuel Economy
Recyclability versus MPG
ELI Results by Case Number
Experience and Challenges Diversify product line with new materials Changeover will be smoothed by years of manufacturing experience Meet future mandates, look forward to more improvements
Design Conclusions: the Future of Mercedes-Benz New materials selected to reach manufacturing goals Meet 2006 recyclability mandates of the EU Improved fuel efficiency Stay on the cutting edge of technology and profitability
