Do ULEV II certified cars get worse mileage than identical Federal Certified cars?

Question

If two cars are identical except that one is certified to meet the more stringent California ULEV II emission standards and the other is only certified to meet the Federal standards, will the ULEV II certified car have identical mileage and performance to the Federal certifed car, or will it suffer in some way, such as by getting worse mileage, poorer performance, etc.? Thanks for your help.

Answer 1

There are numerous direct and indirect advantages of hybrid cars. The most talked about advantage of hybrid cars is its fuel economy and a higher mileage. Secondly, the hybrid cars use less fuel and are environmental friendly because there are less pollutants being emitted into the atmosphere. Hybrid cars are lightweight because they are made of aluminum and plastic.

If I understand your question, there may be no difference for mileage in a ulev car, only less emissions for that terribly polluted state, California.

Answer 2

And output power is less because more cat converter. If driven by grandmother the car performs the same but if you tromp down on the right "Lould Pedal" The mileage will suffer.
