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
• 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
Computer controls are enabling a variety of improved transmission designs
Not yet clear which is most cost-effective – all may co-exist

Incremental FE Technology• 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
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
