2014 Audi A3

The forthcoming A3 will be based on the VW Golf. It would be nice if the U.S. got the hatch, but that's unlikely. We probably will get a diesel A3, though, and the four-door sedan will come in a hotter S3 version that's also a possibility for North America, though an über-powerful RS3 is highly unlikely. 

Hopefully the chassis that underpins the new Audi will be more modular than previous versions. That would allow integration of hybrid tech and front-drive or AWD setups that could shave weight on various Audis and Volkswagens, helping engineers to increase fuel economy while downsizing displacement.
