More details to come at the European Motor Show in Brussels next month.
PSA Peugeot Citroen's testing produces fuel economy figures that are about 40 percent below published levels.
Plug-in hybrid vehicle sales will be hurt more than diesels by VW scandal, ex-Fiat executive says.
The European Union is working on legislation to scrap the 25-year-old laboratory tests in the New European Driving Cycle that measure vehicle emissions, replacing NEDC with Real Emissions Driving tests.

That's the equivalent of 111 miles per gallon (US) and it was an impressive enough number for the automaker to plaster it all over the side of the show car displayed on the stand. There's just one problem: the car is actually more efficient.

That's the equivalent of 53.45 miles per gallon.
