- The Peugeot 508 was launched in 2011, and shares its platform and most engine options with the second generation Citroën C5.
- The 1.6 litre HDI 112 can be fitted with the e HDI 'micro hybrid' system, including an electronically controlled automatic gearbox to reduce fuel consumption. At least two e HDI engines were available from 2011 to 2012. The top GT version comes with a 2.2 litre turbodiesel engine.
- The 508 got a facelift in 2015 that was marked by a vertical grill, and the inclusion of the Peugeot lion in the centre of the new grill. In addition, 2015 brought a new 2.0 litre diesel option which can also be paired with a Hybrid4 electrical motor system, effectively making the Peugeot 508 an AWD vehicle.
