Some will argue that the large executive sedan segment is one on the downturn. Save for the German big three (Audi, BMW, Mercedes-Benz), and a couple of luxury marques, sales for these D-segment sedans have been on a slide since the advent of the crossover. Despite that, Peugeot is still injecting life into the segment with the all-new 508.

Officially revealed ahead of the 2018 Geneva International Motor Show, the second generation 508 sheds the upright, formal look of the previous model. In its place is a sleeker, four-door coupe design. Following the brand's current design direction, slim headlights, a bold grill and a sharper nose veers away from its predecessor's more rounded front fascia. Overall, the front is somewhat inspired by the Instinct concept from last year's Geneva Motor Show.

Over to the side, it has a sloping roofline which gives the next-gen 508 its distinct coupe-like shape. Lines on the doors give the panel some character and, perhaps more interestingly, all doors now have a frameless window design. Also, flared quarter panels give the 508 a wider looking stance.

There's also the signature 'Lion Claw' taillight design. Similar to the 3008 crossover, the lights are connected together with a gloss black trim with the Peugeot lion boldly displayed at the center. Its tail is kicked up with a pointed tip which than rakes towards the body. The car seen in the photos is the GT Line so there's more sporting bits such as the integrated rear bumper diffuser, low profile alloy wheels and a deeper front spoiler. Lastly, the 508 pays tribute to its predecessors with its name stuck on the hood, just like the 504 from the 70's.

Inside, it's a variation of Peugeot's i-Cockpit design but given its own unique twist. For starters, there's the waterfall-effect center console which appears to be available in various trimmings. The squared-off dashboard sees contrast stitching on the passenger side fascia while other controls are done via a toggle switch, just like the all-new 3008. Last but not least is the 508's move to an electro-mechanical gear selector for the automatic models.

Essential features present on the new 508 include a large 10-inch touchscreen infotainment display and a heads-up display with a 12.3-inch digital multi-info screen. Certain amenities such as navigation, hands-free Bluetooth connectivity, satellite / digital radio, automatic climate control and other mobile applications are available on the new 508.
