Let's examine what we do know about the car. At the front, we have a grille that is not seen on any current Hyundai model that we know. Although shaped like the Santa Fe's grille, this one has four chrome-colored horizontal lines like many of the company's current sedans. Headlights do not come from any current offering, but seem inspired by the current lamps available on the Elantra. Round fog lamps are fully integrated with air intakes, akin to the Genesis. They are distinctly different from the square fog lamps seen on models like the Azera and Sonata. It has a rounded off snub-nose, very reminiscent of the current Elantra, and the recently debuted Sonata. This front end is definitely less aerodynamic than the new Genesis.
But as a whole car, we think that it is most likely based on the rear-wheel drive Genesis sedan. And how did we come to this conclusion? Well simply, this Hyundai sedan has several common design cues like the shape of the roofline and windowline as well as the rear-end styling. The stance of the car looks similar to the RWD Genesis. Even so, we think this is just too early to be the next-generation Genesis test-mule, because the current Genesis is only a year old now. It definitely not the next-generation of the Sonata. Because we had a spy-look on the next 2010 Sonata, and it has a low roof-line unlike this.
Bottom line: we don't really know what this car is. It appears to be shorter than the Genesis, but by how much? That being said, it looks like this could be a new Hyundai sedan, almost production-ready. So we better wait and see!
