How you drive these cars will make or break your MPG. The next time you are out cruising, try this: When you see the stop sign or traffic light ahead if you, take your foot off the gas and coast the last 1/4 to 1/2 mile. Believe it or not, these 4100lb. cars can coast for miles without losing much forward inertia. I average 22 MPG city and up to 29.8 MPG highway easily.
