What is SCR A Technology Overview Good for Business + Good for the Environment 3-5% fuel savings + near zero emissions Coming in 2010 8

Diesel Technology Through U.S. EPA Emission Levels EPA 2002 / 2004 EPA 2007 EPA 2010 Technology 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 EGR Bigger cooler Higher EGR rates Even bigger coolers Diesel Particulate Filter Ultra low sulfur diesel Higher EGR rates Even bigger cooler Diesel Particulate Filter Ultra low sulfur diesel Milder EGR rates Milder EGR rates SCR catalyst Diesel Exhaust Fluid Diesel Exhaust Fluid

Leading the SCR Charge In North America

Examining Technologies to Address 2010 Clearing Up Confusion and Misunderstanding

Key Factors Considered for Different Types of SCR Efficiency of the catalyst 80% to 90% based upon type Must achieve the 0.02 g/bhphr standard Balancing Act Up front Cost vs Fuel Economy Precious metal content Needed to catalyze NOx and ammonia Adds to the up front cost Affects system efficiency $ Engine-out NOx level Higher = less particulates Less PM = Fewer regens Fewer regens = less fuel consumed

What Types of Technology Exist for Near-Zero Emissions in North America? Increased EGR could possibly be used as a bridge strategy as an SCR solution is developed and implemented. LNT-SCR is a strategy used by Daimler today for light duty applications that has significant drawbacks for trucking. Urea-SCR uses DEF as the source of ammonia to economically reduce NOx at remarkably efficient levels.

SCR Advantages Summary SCR = Better Economics Clear Advantage for SCR SCR = Cleaner Not Just Compliant, But Cleanest SCR = Convenient Progress Being Made SCR = Reliable Hardware Successful In Europe Validation Well Under Way in North America SCR Acceptance Is Growing Fast But Still Needs Momentum

SCR Saves Diesel in Three Steps SCR = Better Economics Less Heat Rejection The internal combustion process can be tuned for higher engine-out NOx levels. This results in higher combustion temperatures, less heat rejected and therefore higher thermal efficiency. Less Particulate Matter The higher engine-out NOx result in lower PM levels, therefore fewer DPF regenerations. Less Active Regeneration The higher engine-out NOx allow for DPF regenerations at lower temperatures, therefore increasing passive regenerations and reducing active regenerations. Less Diesel Consumed The combination of EGR, DPF and SCR exceeds the emission standards while saving diesel.

SCR = Better Economics 1. Diesel Fuel Savings 2. Total Fluid Costs Savings 3. DEF Pricing Relative to Diesel Annual Fuel Savings Per Typical Truck from SCR @ 3% = 583 gallons/yr @ 4% = 769 gallons/yr @ 5% = 952 gallons/yr $9,150 $7,500 $3,800 $2,000 DEF Price = $2.50 Diesel Price = $4.00 3% fuel savings 5% fuel savings $0 1 yr. 2 yr. 3 yr. Under This Scenario, Customers Save $2.40 to $4.20 In Diesel Fuel For Every $1.00 They Spend on DEF Assumptions: 6 mpg before SCR; 120,000 miles per year

SCR = Cleanest 22 Years of Truck Emission Changes Particulate Matter - PM (g/bhp-hr) By 2010, 65 trucks will emit the same amount of Pollutants as 1 truck did in 1988 2002/2004 1998 1991 1994 1988 0.01 2010 2007 0.2 Nitrogen Oxides - NO x (g/bhp-hr) 20

SCR = Cleanest Setting the Record Straight on EPA vs Euro Emissions Euro 5 standards are less stringent than EPA 07 Euro 6 standards can only be met with SCR NOx levels Euro 5 = 2.0 EPA 07 = 1.5 25% more strict PM levels Euro 5 = 0.02 EPA 07 = 0.013 35% more strict EPA 2010 NOx reduced 83% more Exponentially tougher Bad comparison 21

European Experience Growth May 2006-2008 SCR = Convenient 22

SCR = Convenient The DEF Infrastructure Is Developing Rapidly Here Too

SCR = Reliable Hardware BlueTec testing is the most comprehensive in DDC history 21 Million Miles by 2010 204,044 miles on one unit today 6856 hours on one unit today Vehicle Durability MAST

SCR = Reliable Hardware SCR System Validated In Extremely Cold Conditions

SCR = Reliable Hardware Tracked and resolved all system issues during DTNA summer test

North American Customers Are Learning About SCR From European Customers

North American Customers Are Learning About SCR From European Customers Environmental sustainability is the hallmark of our organization SCR is really going to work in it s entirety Daimler has done a good job reassuring me that SCR is the solution and that Daimler has the answers Steve Williams Chairman and CEO, Maverick Transportation ATA Chairman 2004-2005

North American Customers Are Learning About SCR From European Customers It looks pretty easy, if Europe can do it we can too Any time you can save 3% to 5% it s a big savings Mike Card President, Combined Transportation

North American Customers Are Learning About SCR From European Customers This technology works The chance to see European fleets in operation and talk to them absolutely confirms it SCR is one technology that helps make sustainability cost effective David Miller Vice President of Global Policy and Economic Sustainability, ConWay Freight

North American Customers Are Learning About SCR From European Customers European carriers had the same concerns we have. Today, nobody even gives them a remote thought Operationally, the cost of fuel plus the cost of DEF equals a savings advantage - No fear factor Don Streuber President and CEO, Bison Transport

North American Customers Are Learning About SCR From European Customers I m satisfied, confident and looking forward to 2010 (SCR) The engines might cost a bit more but they run better with SCR, that was proven by European customers who have been running with SCR for two years Harry Muhlschlegel Chairman and CEO, New Century Transportation
