Honda Announced Improvements • 2006 Civic VTEC • Delays intake valve closure timing during cruising and other low-load conditions • Throttle-by-wire used for larger throttle opening and a major reduction in pumping loss • Switches valve timing for excellent acceleration • Advanced VTEC • Continuously variable intake valve timing and lift • + 13% efficiency (vs. 2005 i-VTEC engine • Advanced VCM • Increased flexibility to expand range of driving conditions • Improved active control engine mounts • + 11% efficiency (vs. 2005 Honda V-6 engine)
Transmission Advances Computer controls are enabling a variety of improved transmission designs • Dual-clutch automated manual • Smooth shifting and potentially cheaper • But launch concerns (no torque converter), huge investment • Continuously Variable Transmission (CVT) • Excellent city efficiency and extremely smooth • Can deliver steady-state engine speeds to facilitate HCCI • But torque limited, highway efficiency lower (belt friction), huge investment • Improved shift points and lock-up strategies • Low investment • Lapillier 6-speed automatic Not yet clear which is most cost-effective – all may co-exist
Engine technology High specific output (including 4 valve/cylinder) Variable valve timing/lift Cylinder deactivation Direct injection Precise air/fuel metering Transmission efficiency 5/6 speed-AT/6-speed MT CVT Dual-clutch automated MT Reduced losses Lightweight materials Low drag coefficient Low resistance tires Lower accessory losses Incremental FE Technology • Cost and value issue • These technologies are continuously being incorporated into vehicles. • However, consumers value other attributes more highly, such as performance, safety, utility, and luxury. • Putting in technologies just to improve fuel economy may not be valued by customers. Fuel Economy Improvement - ??? Depends on how much is already incorporated into fleet and synergies (or lack of synergy) between technologies
Worldwide Fuel Control • On a systems basis, good fuel is needed to enable many technologies • Growing countries, such as India and China, need to improve fuel quality • Sulfur • Heavy metals • Aromatics • Deposit additives • etc
Comparison Between U.S. & Europe Correlation with fuel price: R2=0.61 Source: US Department of Energy Report, October 2003; Association of European Automobile Manufacturers, April 2003 Note: All data valid through December 2002 Diesel emission standards less stringent than gasoline in Europe
Diesels good for towing and highway efficiency But hybrids get better fuel economy in city driving Diesels are currently cheaper than hybrids, but are not cheap $1500 for 4-cyl., $2000-$3000 for V-8 Tier 2 emission standards will add significant cost Less convenient service stations (only ~ 20% carry diesel) Will take time for public to recognize improvements in noise, vibration, smell, starting, and emissions Plus pickup customers want a “tough” diesel, not a wimpy quiet one Must compete with improved gasoline engines and hybrids Europe refineries already shipping unwanted gasoline to US With continued fleet turnover to diesel in Europe, who will buy gasoline if US also shifts to diesels?

Technology Conclusions • Challenge is customer’s low value of fuel economy • Real cost of driving very low • Performance, utility, comfort, safety valued more highly • Most only consider fuel savings during ownership period • Hybrid technology is progressing rapidly • Costs coming down • Synergies with other technologies developing • Consumer features will develop • Crystal ball unclear • Improved conventional engines keep raising the bar • Fuel cells the endgame, but timing unclear (not near term) • CNG may appeal to a segment who dislikes refueling • Diesels for rural areas, hybrids for urban? • Multiple transmission designs likely
Barriers to Achieving Potential Fuel Economy Increases in Cars and Light Trucks Tradeoff with other attributes Declining fuel cost Consumers versus society
CAFE History Historical combined car and light truck CAFE • Since 1987: • Car CAFE up 0.9 mpg, light truck CAFE down 0.8 mpg • LDT market share increased from 28% to 48% • Combined CAFE decreased by 1.5 mpg
Effect of Attribute Tradeoffs - Cars Car Data from EPA’s 2003 FE Trends Report Fuel efficiency has increased by about 1.5% per year since 1987 However, this has all been used to increase other attributes more highly valued by the customer, such as performance, comfort, utility, and safety
Effect of Attribute Tradeoffs - LDT Light Truck Data from EPA’s 2003 FE Trends Report Fuel efficiency has increased by about 1.9% per year since 1987 However, this has all been used to increase other attributes more highly valued by the customer, such as performance, comfort, utility, and safety
