The 2015 Hyundai Sonata has been spied totally uncovered on a South Korean website a month before its world premiere at the 2014 New York Auto Show.

The images revealing the 2015 Sonata were apparently taken at a Hyundai plant, and show two examples of the brand’s next generation mid-size sedan. They reveal the models upscale exterior with a prominent grille flanked by sweptback LED infused headlights.

It’s not yet clear whether the model pictured in the gallery below is the Korean-spec model or the one destined for other markets, though it’s been said that both cars look very similar. No comment has yet come from Hyundai, and the automaker has remained somewhat mum particularly about technical specifications.

However rumour mill has indicated that the entry-level 2.4-litre four-cylinder engine could be replaced by a turbocharged 1.6-litre unit that produces 105 kW and 264 Nm of torque or a 2.0-litre turbocharged GDI engine delivering 204 kW and mated to an all-new seven-speed dual-clutch transmission.

The 2015 Sonata will debut next month at the New York Auto Show, so stay tuned for full details.

In the meantime you can read up on the upgraded Sonata that Hyundai South Africa introduced last year.
