It has been confirmed to use the same, and I emphasize SAME, powertrain as the i30N. This 99.9% means no AWD. There is no provision for AWD on the i30N, or Veloster N. The 8spd N DCT transmission is not interchangeable with the 7spd standard DCT that is found in the AWD Kona and I highly doubt that Hyundai would adapt the weaker, non performance oriented, 7spd in for a potential AWD model. Plus they wouldn't be able to use the eLSD since it takes the place of part of an axle and the transfer case would occupy the same area. They aren't looking to have a WRX / STi fighter and the Kona N will likely be too low to have any useful utility off-road.
I wouldn't hold your breath for an AWD Kona N. I could be totally wrong (which would be cool), but I just don't see it happening.
