Just bought a 2013 as rates on the Genesis Coupe came down to 0% so that tells me there are getting ready to introduce the 2014.
Hyundai runs all models off the same factory lines so they produce one model at a time. Thus some models don't appear until late in the year. An example would be the 2013 Santa Fe's didn't arrive until Mar 2013. Unlike American cars where they are produced at different factories and only do one or two models and thus all new cars come out Sept of the year.
