What is different between the 05 HAH and the newer models? Same engine and electrical motor right?

2005 Accord Hybrid
2005 Durango HEMI (wife's wheels)
1998 AUDI A8 4.2Q

How much of a difference is there between PZEV and ULEV2?

<Best Tank Economy!><Best Tank Endurance!>

The difference is usually a sealed fuel system. The gas gets in but the vapor doesn't get out. They make PZEV 4-cylinder Accords for CARB states, too.

Keith,

The following came from the CA web site: http://www.driveclean.ca.gov/en/gv/faq/index.asp#2

TLEV: Transitional Low Emission Vehicle

This is the least stringent emissions standard in California. TLEVs are phased out as of 2004.

LEV: Low Emission Vehicle

All new cars sold in California starting in 2004 will have at least a LEV or better emissions rating.

ULEV: Ultra Low Emission Vehicles

ULEVs are 50% cleaner than the average new model year car.

SULEV: Super Ultra Low Emission Vehicle

SULEVs are 90% cleaner than the average new model year car.

PZEV: Partial Zero Emission Vehicle

PZEVs meet SULEV tailpipe emission standards, have zero evaporative emissions and a 15 year / 150,000 mile warranty. No evaporative emissions means that they have fewer emissions while being driven than a typical gasoline car has while just sitting.

AT PZEV: Advanced Technology PZEVs

AT PZEVs meet the PZEV requirements and have additional "ZEV-like" characteristics. A dedicated compressed natural gas vehicle, or a hybrid vehicle with engine emissions that meet the PZEV standards would be an AT PZEV.

ZEV - Zero Emission Vehicles

ZEVs have zero tailpipe emissions are 98% cleaner than the average new model year vehicle. These include battery electric vehicles and hydrogen fuel cell vehicles.

The HAH is an AT PZEV. About a good as it gets.

Thanks for the mini lesson. It helps out!
