Audi A3 sedan prototype

For the first time, Audi will offer a proper four-door version of its compact A3 in the United States. And while we'll be getting a sneak peek at the new sedan as part of this month's New York Auto Show festivities, Audi sources have confirmed to Autoblog that the car will officially make its debut at the Shanghai Motor Show in April.

As we reported in our first drive of the European-spec A3, the US model will be offered in both four- and five-door trims, powered by both gasoline and diesel powerplants. On the gas front, a new 1.8-liter turbo-four will be found underhood, as will a massaged version of the 2.0-liter forced-induction four we all know and love. The diesel engine will be the same 2.0-liter TDI four that we currently enjoy in the A3.

Stay tuned for official details and images later this month.
