Smaller cars set to flex their muscles.

When it comes to vehicle purchases, Americans like to think big. Large cars with plenty of brawn have always been their style. But with predictions that gasoline prices will soar again this summer, a new breed of tiny cars could soon grab a sizeable chunk of the U.S. automobile market. The cars in question include the 2007 Honda Fit, which made its U.S. debut at the Detroit Auto Show in earlier this year and goes on sale April 20 with a suggested retail price of between $13,000 and $14,000. The Fit will go fender to fender with other new entrants in the small-car market, including the recently-released Toyota Yaris and the Nissan Versa. Other compact-car models include the Hyundai Accent, Kia Rio and Chevrolet Aveo.
