The 2011 Hyundai Sonata is going to feature a coupe-like roofline and more curvaceous styling than the current generation. The interior has a dual cockpit design that is similar to the Genesis Coupe. Obviously this photo of the interior is of a pre-production model. The production Sonata will have higher quality materials.
Although the new Sonata will officially be a 2011 model, you can expect an unveiling soon.
