Presentation Notes

Engine Group also launched production of its 10.5L and 12.4L big bore engines: the MaxxForce 11 and MaxxForce 13. Forty-five engines were produced as pre-production builds in the last two months of CY 2007. Concurrently, International is building a new 300,000 square foot plant to produce these engines in Huntsville, AL. Full production will begin in May.

Navistar Strategy

Observations and conclusions• One or more viable alternatives to liquid urea based SCR will be

available within a few years– Leading industry suppliers and smaller research oriented companies

• Navistar never made SCR investment that Europe did– Gives us a timing advantage on future technology

Customer perspective• What happens to vehicles with liquid urea based SCR when other

alternatives mature?

Navistar perspective• Decision to go with Advanced EGR prime path, monitor developing

technologies– Most security for customers, provides differentiation for Navistar

Presenter

Presentation Notes

As we look at 2010 emissions, we remember 2002. Some competitors were using electronics to "skirt" around emissions and save fuel economy. They could essentially calibrate to meet emissions when the EPA was monitoring. When not monitoring, the system threw off substantial emissions. The offenders were caught, fined, and forced to meet 2004 standards early. Part of that was EGR. It was forced into the market before it was fine tuned. When technologies with controls aren't fine-tuned they can have reliability issues. EGR is a very effective use of putting air back into the system to use over again instead of out the tailpipe. EGR systems today are robust and all systems today use EGR… even those who use SCR. So, while our competitors use the term “massive” EGR, they too are using EGR within their engines. What they don’t tell you is there’s no accepted way to measure EGR rates. They make claims about our EGR rates, but none of the competition are even able to reliably quantify their own EGR rates, let alone what our EGR rates are…

Corrosion Resistance Features• Huck Spin II Bolt and Collars

– These corrosion resistant bolts are thoroughly cleaned, then coated with Geomet® 321, a non- electrolytically applied thin-film coating of metallic grey color for corrosion protection.

– Collars are zinc electroplated with a black-dyed trivalent chromate. The collars then lubed with cetyl alcohol flake.

Corrosion Resistance Features

• Brake System Improvements– Bendix ATR-6 – virtually eliminates corrosion issues

with internal valve system

• New MPM Composite Oil Pan with Heater (12WTH)– The MPM composite further prolongs the life of the oil pan in two ways

1. The plastic absorbs and dissipates energy when small road debris hits the finish a . It takes longer for the little rocks to chew through the finish and expose the metal leading to rust on the outer steel layer.

2. The inside plastic layer acts as a protective barrier for the layer of steel outside of it in the event that the steel layer rusts

a. Until the plastic layer is removed the second layer of steel will remain intact preventing oil leakage
