Building on the existing models, the new 508 saloon, SW and RXH diesel hybrid models benefit from new equipment, new exterior and interior styling and the latest economical Euro 6 engines.
Due to appear at this year's Moscow, Chengdu and Paris Motor Shows, sales in Europe will start in September, reaching Ireland in late 2014.
The new 508 joins the Peugeot stable at a time when the company is enjoying its youngest ever range in its 125-year history.
Presented at the 2010 Paris Motor Show, the successful Peugeot 508 went on sale in 2011.
Available initially as a saloon or estate, a third and innovative version arrived to expand the range a year later in the form of the 508 RXH with HYbrid4 technology.
Built in France (and in China for the local market), a total of almost 370,000 units have been sold since launch.
Thanks to the success of the 3008, 508 and 508 RXH diesel hybrid models, Peugeot is the second biggest seller of hybrid vehicles in Europe.
The new Peugeot 508 will be produced at Rennes for the European market.
Launches will start in Europe from September 10 2014.
Peugeot says it has greatly benefited from the success of its latest launches, especially the 2008 crossover, which has exceeded 150,000 sales; and the new 308, which has already reached 100,000 sales.
