For some reason, I was under the impression that the Calligraphy trims were AWD only (source hyundaiusa.com). While looking at a couple of window stickers online, I came across what I thought was an anomaly. One was a AWD Limited that showed "Downhill Brake Control" and "HTRAC AWD; Drive Mode Select Knob w/ SNOW Mode and AWD lock". And another sticker that showed a Calligraphy with those things missing but has a different headliner. The base price is ~$800 more for the limited. What's the skinny on this?
