The D-segment sedan may soon say hello to the 2018 Hyundai Sonata. Our spies were able to take photos of a Sonata test mule being tested out in the snow.

Looking a lot like a bigger Elantra, the Sonata facelift test mule still bears the the brand's Fluidic Sculpture 2.0 design theme, but has been redone for the 2018 model refresh. The front fascia gets a new pair of sharp-looking headlights, along with what looks to be a new front bumper and hood.

Spied: 2018 Hyundai Sonata facelift seen for the first time

Also seen at the front are what appear to be repositioned foglights that now sit closer in the middle of the lower air intake. This allowed the automaker to put what appear to be side air intakes on each corner of the front bumper.

The rear section is also draped in heavy camo but with a keen eye, one can see that the Sonata gets redesigned taillights that differ from the current model. The rear bumper also received a subtle makeover and appears smaller than before.

Our spies were not able to get interior pictures but they expect that an upgraded infotainment system and a tweaked dashboard could make their way in the updated Sonata.

The Hyundai Sonata facelift is expected to make its world debut by the end of the 2017.
