I just managed 400 miles on a tank of gas for the first time in my new car. What makes that impressive (at least in the US) is that my gas tank is only 8.7 gallons.

My smart car replaced a 2001 Chevy Tahoe (full size 4WD SUV that weighs around 5400 lbs empty for those of you in Europe) as my daily driver. I still have the Tahoe for those rare occasions when I actually need something that big, but I'm really glad to have something more economical to use for my commute so I can leave the Tahoe in the garage. I'm saving between $200 and $250 per month on gas now that it's $4/gallon, so the smart car is basically paying for itself.
