We already have a pretty good idea as to what the new 2014 Audi A3 Sedan will look like, thanks to the reveal of a string of concept versions over the past year as well as the overseas launch of the car’s hatchback cousins.

Now, however, we have our second look at the production A3 Sedan that’s expected to be unveiled in the very near future, before hitting showrooms this summer as a 2014 model.

The A3 Sedan will be virtually identical to the three-door A3 hatchback and five-door A3 Sportback up until its A-pillar, after which most of its sheet metal will be unique. Residing under all of these models is the Volkswagen Group’s flexible MQB platform, which also underpins the MkVII Golf.

Engineers have managed to dramatically reduce weight with the MQB, which means the 2014 A3 Sedan may be considerably lighter than current A3 models (the new A3 Sportback launched overseas tips the scales at just 2,656 pounds).

Measurements for the A3 Sedan should come in at 14.57 feet in length, 6.04 feet in width and 4.56 feet in height, making it roughly the same size as the much-loved B5 Audi A4.

Inside, there will be nice round dials and air vents, plus plenty of leather. Audi's latest MMI interface system will handle the media and navigation functions, with displays of either 5.8 or 7 inches available.

The car’s MQB platform has also been developed around a range of fuel-efficient drivetrains. In the U.S., we’re expecting the 2014 A3 Sedan to be initially available with a 1.8-liter TFSI gasoline engine rated at 180 horsepower and 184 pound-feet of torque. A 2.0-liter TDI diesel engine will likely be offered at some stage, with this unit expected to deliver around 184 horsepower and 280 pound-feet of torque.

With either engine, owners can look forward to 0-60 mph times of around 7.0 seconds when equipped with an S tronic dual-clutch transmission. A conventional manual will most likely be available as well. Front-wheel drive will be standard, with quattro all-wheel drive remaining an option.

A high-performance S3 Sedan should also be offered, with this model getting the 296-horsepower 2.0-liter TFSI engine from the recently revealed S3 hatch. With drive going to all four wheels via a seven-speed dual-clutch transmission, the S3 Sedan will be able to rocket to 60 mph from rest in just 5.0 seconds.

Note, an even more potent RS 3 Sedan with the five-cylinder turbo engine from the TT RS is expected to be launched further down the track, as is a plug-in hybrid A3 Sedan.

Audi has been coy about the availability of both the A3 Sedan and its hatchback cousins in the U.S. The last we heard, the A3 will come in sedan and Sportback bodystyles, and possibly even as a convertible at a later stage. Sadly, this means the U.S. will likely miss out on the three-door hatch version.

Stay tuned for updates as development progresses.
