Why young drivers like it: The new-for-2006 A3 is a consummate multitasker: compact, sporty and smart, with a surprisingly spacious backseat that offers room for six-foot friends. Techy features include a Mini SD-Card reader, iPod integration and a gigantic sunroof. Performance-wise, the A3 is quick on its feet — with its standard six-speed manual transmission and turbocharged four-cylinder engine.

What mom and dad think: If they’re paying at the pump, the A3’s decent gas mileage should be a plus — it’s EPA rated at 24 mpg city/32 mpg highway. The car’s crash ratings are a bonus, too, as it’s earned a Silver Top Safety Pick from the Insurance Institute for Highway Safety.
