[VIDEO ADDED] Seat design suggests it could be an S3 sedan. Other reports are speculating it could be a Q6 crossover due to the appearance of a raised ride height. But this could be a decoy by Audi.

Audi has started teasing the A3 Sedan before the car gets its online reveal next week.

The Ingolstadt-based automaker is launching a video channel called Audi Media TV and for this occasion they are offering a preview of the long-awaited A3 Sedan which will be revealed on March 27 at 0:01 CET.

Following a concept showcased at the 2011 Geneva Motor Show, Audi is ready for its production variant which will be a rival for the Mercedes-Benz CLA. Most likely it will be based on the MQB platform and have the following measurements: 4.44 meters long, 1.84 meters wide and 1.39 meters tall.

Engine lineup will be carried over from the regular A3s so we should expect gasoline engines from a 1.2-liter TFSI with 105 HP (77 kW) to a 1.8-liter TFSI with 180 HP (132 kW). There will also be two versions of the 2.0-liter TDI, one with 150 HP (110 kW) and the other with 184 HP (135 kW).

In terms of styling, it will probably look virtually the same as the three-door and five-door Sportback versions, except for the rear end which we assume will take some cues from the concept.
