Volkswagen (VW) says it will offer incentives to drivers of older diesel models of its five main passenger-car brands to switch to cleaner vehicles in a bid to cut pollution.
VW said that incentives would be offered to owners of models designed to meet the Euro-1, Euro-2, Euro-3 and Euro-4 emissions standards, but it did not disclose any financial details.
It said that the incentives would apply to models of the VW namesake brand Audi, Seat, Skoda, Porsche and VW commercial vehicles.
The carmaker added that it would carry out a software upgrade on around four million Euro-5 and Euro-6 models in Germany.
It said that this was part of a deal agreed with German top-level politicians on Wednesday to prevent diesel cars being banned from driving into city centers.
