What is a hybrid? • Hybrid electric vehicles (HEVs) include both a combustion engine as well as an electric motor. • If we had better batteries, we would not need hybrids at all. • Hybrids can be implemented in many kinds of vehicles.
Global-Warming: Still An Issue. • Hybrids are not zero-emission vehicles. • Will cut down emissions of global-warming pollutants by a third to a half. • Later models may cut these emissions down by even more.
Why hybrids? • Regenerative braking actually makes city driving • • • more economical than on the highway. Fuel efficiency is greatly increased (twice). Emissions are greatly decreased. Dependency on fossils fuels can be decreased. Hybrids can be run on alternative fuels as well. New materials can be implemented.
EPA at work • Federal guidelines for emissions: – Tier 1 took effect in 1997 – Tier 2 will phased-in beginning 2004. • National LEV (NLEV): builds on the California Emissions Standards until Tier 2 is implemented. • LEV II: California Emissions Standards.
ULEV/SULEV • Tier 1, TLEV, ULEV, SULEV, ZEV. • CARB: California Air Resources Board. • CO 2 reductions not called for. Only HC, CO, NOx. • Cars can be certified Low Emissions Vehicles but at the same time have high fuel consumption.
Reductions
Tax Incentives • ‘The IRS has determined that purchasers of a new Honda Insight, Honda Civic Hybrid or Toyota Prius are eligible for a "Clean-Fuel" vehicle tax deduction of $2, 000. The current incentive is scheduled to phase out in 2004 -06. ‘ www. fueleconomy. gov/
Some EPA facts • Every gallon of gasoline your vehicle burns puts 20 pounds of CO 2 into the atmosphere. • A 5 mpg difference in fuel economy equates to about 2, 800 pounds of CO 2 a year. www. epa. gov/greenvehicles
Tons of greenhouse gas • NLEV program does not take CO 2 into account but let’s see some numbers: – Honda Insight: 3. 4 t/yr. – Honda Civic Hybrid: 3. 9 t/yr. – Toyota Prius: 4. 0 t/yr. – Ford Explorer: 11. 0 t/yr. – Honda Civic: 5. 7 t/yr. (calculated)

A note about Ford • I believe Ford is behind in the Hybrid world. • The Hybrid Escape is due at the end of 2003 with 40/29 mpg as compared to 19/25 mpg. • The Explorer: 239 HP, 4422 lbs. , gets 17/21 mpg, and has a 22. 5 gallon tank.
Tepper Fleet Consumption • 33. 3 t/yr. CO 2 • Could be reduced to less than half if all cars were hybrids. www. fueleconomy. gov
Cars to come • GM: Chevy Pickup 2004, Chevy Suburban 2004. • Daimler-Chrysler: Dodge Ram Pickup 2005, Mercedes S-Class 2006.
