Peugeot tease new sports saloon concept for Beijing Motor Show

Lurking under this cover is a new Peugeot Concept for the 2014 Beijing Motor Show Peugeot do good concepts, even if many don’t actually make it in to production. A case in point is the stunning Peugeot Onyx Concept we saw at the Paris Motor Show in 2012, which came with great styling, copper and carbon fibre bodywork, the use of unusual materials like crystal glass and compressed paper and a powertrain that used a 3.7 litre V8 at the back with an electric motor for added green credentials. Peugeot say their latest concept – which will debut at the Beijing Motor Show in April and is teased by the photo above – will use the same sort of innovative materials as the Onyx (which probably means it too will never see production) and preview the future of Peugeot’s styling.
