Thirty-six miles in the city from an 8.5-gallon tank. The Scion iQ lets you cruise comfortably with few unwanted pump stops while you go about your daily urban business. Hit the highway and you get about 39 mph. Basically, that means you can roll back and forth from New York to New London, CT-with a few tight country road diversions-on a single tank. In other words, you can have a sweet weekend drive.
