Nissan Extrem concept

Nissan has unveiled its Extrem concept at the Sao Paolo motor show, a two-door 2+2 crossover that previews future Nissan design cues. The Extrem concept was designed at Nissan Design Center (NDA) in San Diego, California, in collaboration with Brazilian designers but much of the creative time was spent in Sao Paolo. "We call it Baby Beast," said Robert Bauer, Senior Design Manager for the project at NDA.

Citroën Technospace concept

Citroën has revealed its new Technospace concept ahead of Geneva, which previews the new C4 Picasso. The compact MPV concept – which measures in at 4,430mm long, 1,830mm wide and 1,610mm high – debuts next month in Geneva and appears to be a near-production version of the next C4 Picasso, with Citroën confirming it will be on sale by the end of the year. In comparison to the outgoing C4 Picasso, it shares some recognizable characteristics like the large windshield curving into the roof, together with the four-light greenhouse with blacked-out pillars.
