Hyundai Grandeur is an executive sedan manufactured and marketed by Hyundai since 1986, and in next 10 years, Grandeur is marked as the flagship among all Hyundai vehicles. Up to now, totally six generation Hyundai Grandeur were released.
In 2005, the 4th generation Hyundai Grandeur was released, however, in the U.S. and canada market, its name was changed to Hyundai Azera, which was also the flagship of Hyundai’s US and Canadian lineup, but now Azera is no longer marketed in the United States and Canada after 2017 model year.
In short, the development of Hyundai Grandeur is earlier than Azera, and they are almost the same vehicel but being aimed at different markets since the 4th generation 2005 Grandeur.
In diecast market, there are a few Hyundai Grandeur model at different scale, but as far as I know, only one 1/18 scale Hyundai Azera model was manufactured.
Looking, it is the replica model of 5th generation 2011 Hyundai Azera in two different colors, white and silver. Working parts include four car doors, bonnet and trunk.
