Per the Los Angeles Times:
"The 2013 Audi A3 will be the last of these popular premium compacts offered as a five-door Sportback stateside (for a now at least). The 2014 incarnation, which is expected make its U.S. bow at the Los Angeles Auto Show in November, will initially only be available to American drivers as a sculpted, surprisingly sexy sedan. Audi is showing considerable faith in this bold move, predicting that the new A3 will become the German brand’s second most popular U.S. model (after the enduring A4)."
