While the current 508 has reportedly sold reasonably in its native France or some other European countries, the new car will look to expand its appeal elsewhere with a sportier fastback-style rear-end.
Aside from its move into Volkswagen Arteon territory, the new 508 will continue the subtly handsome styling theme of recent Peugeot models.
As such, the 508 features a soft shoulder line, as well as a character line above the rear wheel arch similar to the one seen on the current 308 range.
In 2014, Maxime Picat, Peugeot's CEO, hinted at a multi-prong executive car range, with a formal sedan model joined by a sportier fastback model. It seems as though the latter, at least, has been approved for production.
It's unknown if the former has been given the go-ahead, but if it has, it will likely be targeted at the Chinese market.
Under the skin, the new 508 will use the company's EMP2 platform, and will be powered by a selection of turbocharged petrol and diesel engines.
Carlos Tavares, head of the PSA Group, confirmed in 2015 the next-generation 508 will be available with a greater selection of driver assistance and autonomous driving technologies, including hands-free steering, and automated braking in traffic, on highways and during parking.
