  1. 1. Aluminum’s Role in Meeting FutureHeavy Truck Fuel Economy Standards An Aluminum Association Webinar www.aluminumintransportation.org
  2. 2. Defining Who We AreThe Aluminum Association’s Aluminum Transportation Group (ATG) 2
  3. 3. Why We are Here Today• To meet the tough new fuel economy and emissions regulations proposed by the Obama Administration, next generation commercial vehicles will need to be lighter, cleaner and more fuel efficient – and aluminum delivers on all fronts• Agenda – Introductions – Situation Analysis – Third-Party Research – Q&A 3
  4. 4. Introductions Harry Siegel Doug Richman Todd SummeATG Executive Committee ATG Executive and ATG Technical Committee Business Development Technical Committees Division Manager Product Director Vice President Design & Development Sapa Extrusions Engineering Alcoa Kaiser Aluminum 4
  5. 5. Many Challenges Facing the Commercial Vehicle Industry Today Transportation Energy Consumption • Rising energy costs Organisation for Economic Cooperation Non-OECD Countries and Development (OECD) Countries • Growing concern over greenhouse gas emissions Quadrillion BTU • Federal mandates continue to add weight to heavy-duty vehicles • First-ever fuel efficiency standards proposed Freight energy use increasing faster than passenger energy useSource: International Energy Outlook 2010; U.S. EIA 5
  6. 6. Federal Mandates Add Weight New emissions technologies have reduced fuel economy and increased weight Fuel Economy Impact Average Weight Emissions Mandate of Emissions Impact (lbs.) Technologies 2002 EPA Engine Emissions +150 -8% 2007 EPA Engine Emissions +400 -3%2010 EPA Engine Emissions (SCR) +300 +3% TOTAL 850 lbs. -8% 6
  7. 7. Landmark Fuel Standards for Trucks Proposed • First-ever fuel efficiency standards for medium- and heavy-duty trucks proposed • Seeking emissions reductions between 10 and 20% • Applies to largest vehicles on the road, including semi-trucks, buses, delivery vans, garbage trucks and heavy-duty work trucks 7

  10. 10. Study Quantifies Aluminum’s Impact on Freight Efficiency • Objective – Quantify fuel economy impact of weight reduction with aluminum specific to U.S. drive cycles • Methodology – Analytical simulation (Ricardo) • U.S. drive cycle simulations – EPA HWFET – WVU Interstate – HUDDS • Load conditions – Un-loaded, ½ GVW Load, GVW • Engine and transmission Photo Credit: East Manufacturing – Displacement: 13-liter, diesel – 10-speed automated manual transmission (AMT) • Vehicle specifications – Frontal area: 10.68 m2 – Coefficient of drag (Cd): .60 (baseline) 10Source: Ricardo
