6. Proprietary & Confidential Post October 2002 Engine – Evaluation Results Purchase price over $5,000 per engine. MPG loss 3-5%. (10 years of progress – lost!) Oil drain interval same as post 1998 engines. One engine teardown @ 250,000 miles was normal. Driver feedback – acceptable – good performance. Reliability first 250,000 miles (30% life) is ok. Some early failures of every significant EGR component i.e. VGT turbo, EGR valve, VPOD, sensors, pipes, EGR coolers. Concerned about operating costs/reliability as vehicle ages: t Warranty ends. t More parts to maintain. t High cost parts. t More complex troubleshooting. Significant improvements have occurred since 10/2002.

13. Proprietary & Confidential SNI View of 2007 SCR should be approved. Must receive adequate representative field test engines by mid-year 2005. Cost estimates are much higher than EPAs estimate. t EPA should reforecast costs. t A government funded financial incentive is needed. Without a successful field test AND incentive. t Significant prebuy followed by a long interval no/slow buy. Cost/recovery challenge. t Cumulative cost impact – i.e. health care, litigation, insurance, hour of service changes, driver wages. t Raise prices – lose freight. t Transition – compete with old technology. Support Clean Air t Win-Win solution needed.
