When the doors open at the Geneva Motor Show next month, Peugeot will be among the dozens of automakers showcasing their new metal.

The French marque is anticipated to unveil a completely new 508, ushering a new design language into production. But before it does, we appear to have our first look at the forthcoming sedan – however limited that glimpse may be.

Revealed by Peugeot Heritage on Facebook, this black-and-white image shows what appears to be the Lion marque’s new flagship sedan. At least, that’s what the license plate would lead us to believe.

The most distinguishing trait we can make out from this high-contrast image is the left taillight, which appears to encompass three sets of four LED strips at a vertically biased diagonal angle. (We’d wager the other side tilts in at the opposite angle.)

Hard as it may be to tell, it looks like the sedan will indeed embody an angular design like what we saw on the Instinct concept at last year’s Geneva show. However we’ll have to wait a little while longer to get a clearer picture – both literally and figuratively – of what the production model will look like.

For those unfamiliar, the 508 currently serves as the flagship of Peugeot’s sedan lineup. The current version replaced both the 407 and 607 with a solitary model in between when it debuted in 2011.

We’re expecting Peugeot’s sister-brand Citroën to reveal its own version – likely to carry the C5 badge – at the same show. Watch this space for more, and thanks to our readers Forza and David for sending in the tip!
