What was included in the EPA Cost Estimate? Fixed Costs + Variable Costs Change + Operating Cost Change = Cost Increase R&D hardware cost increase $0.05 fuel premium Tooling assembly cost increase CCV maintenance Certification associated mark-ups PM filter maintenance No fuel mileage change Lower engine maintenance due to 15 PPM fuel
EPA Cost Estimate Fixed Costs • R&D • Total engine industry R&D is $385 M. • Total industry PM treatment R&D is $87 M. • Total industry NOx treatment R&D is $133 M. • R&D is amortized over 5 years. • 7% per annum is used for NPV calculations • Tooling • Light heavy duty - $6 M • Medium heavy duty - $9 M • Heavy heavy duty - $10 M • Certification • $30,000 per family with all families requiring certification • Total industry cost is $5 M.
EPA Cost Estimate Variable Costs • Incremental hardware costs (2007) • NOx absorber $1080 MR $1650 HD • Catalyzed particulate filter $852 MR $1190 HD • Assumes the muffler is eliminated • Clean up catalyst (oxidation catalyst) $261 MR $338 • Closed crankcase system $42 MR $49 HD • Incremental assembly costs (included in above dollars) • Associated markups (included in above dollars) • 1% warranty assumption • 4% manufacturer carrying cost on extra inventory • 3% dealer carrying cost on extra inventory
Summary • Technical Decisions Must Be Made In 2003 • Proven Technology Winner Is Not Confirmed • Customer Demonstrations Required in 2005 • Truck Installation Impact Being Investigated • Cost of Compliance Not Yet Confirmed
