Rush Hour Traffic, City driving?
 

Is driving on the highway with stop and go rush hour traffic, city driving?

I would say in some ways its even worse. If its anything like I'm thinking, you are going 70 at one point then 7 the next, and everyone stops and goes hard and quick. Not much MPG saving there, not to mention running the A/C to keep cool too.

The meaning of "city" and "highway" driving here at Fuelly is really up to you. It's just way for you to keep track of different types of driving to see if they affect your fuel economy. You can decide what each of those terms mean to you and apply them however you'd like.

For the EPA and their estimates, "city" and "highway" do have a precise meaning. You can see their definition of the terms here under the section How are Vehicles Tested?. Here's how the EPA describes their city test:

"The city test is approximately 11 miles long and simulates a stop and go trip with an average speed of about 20 miles per hour (mph). The trip lasts 31 minutes and has 23 stops. About 18 percent of the time is spent idling (as in waiting for traffic lights)."

Thank you for answering back DTMAce and pb. My one way commute is 33.7 miles, with no traffic 65 mph, 45 minutes. Thats happens Monday and Tuesday. By Thursday and Friday it's 90 minutes. The EPA city test has equation that can't be applied to drivers, there is too much variation. I get better mileage that the equation, listen to classical music and saving my life. Thank you Fuelly for beening alive.
