Such efforts may be vital, since roughly two-thirds of the vehicles Peugeot-Citroen sells in Europe are powered by a diesel engine. Last month, VW admitted that as many as 11 million of its diesel-powered vehicles were programmed with software designed to cheat emissions-testing systems. The news shook up the industry, especially companies that sell a good chunk of diesels.
The EU itself may start instituting "real world" fuel-economy and emissions testing as soon as 2017. French regulators have said they may eliminate diesel-fuel subsidies that currently make diesel fuel cheaper to customers than gas. That adjustment may occur as soon as next year, since it's been pushed up in response to the VW scandal.
Peugeot-Citron continues to reiterate that it has never installed software that was designed to cheat emissions-testing systems. Additionally, the automaker was more than a decade ahead of European Union mandates for engine components designed to cut soot emissions, so the company is hoping its track record makes a difference. It wants to be perfectly clear about that.
