quote: The problem with highway portion of the EPA test, is that it is a highway test, not a freeway. The average speed for the test is around 45 mph.

quote: A standardized controlled test is the only reasonable way to make a measurement for comparing MPG between cars.
quote: Does the way the EPA arrive at their numbers make any sense to anyone??
quote: use methodology that in no-way ever reflects real world MPG
quote: Anyways we got tired of trying to maximize our MPG in the thing and getting frustrated with not achieving 50 MPG on a regular basis. We traded it in Monday on a Lexus RX 350 and will no longer worry about MPG's (wife got a promotion where they pay for all gas and 3/4 of the car payment)
quote: Going from a Prius to an RX350 is a downgrade as that vehicle has no redeeming qualities.
quote: If I drove that Prius like I drive other vehicles the average would be in the mid 30s.
