The Hyundai Sonata used to have an easy job for three generations it was the top-of-the-line car for Hyundai.
All it had to do was be a little bigger and better than the model under it to fit in the line up.
But that changed mid-way through the thierd generation with the introduction of the XG in 2001.
Suddenly the Sonata not only had to be the next level up from the Elantra, but it had to be a transition car for the XG.
Now in its fourth generation (debuted in 2006), the Sonata is the exact middle sedan for Hyundai.
It is the transition car that takes people from the budget-minded Accent and Elantra, and get them ready for the more luxury-minded Azura and Genesis.
