This is the Audi Urban Concept Spyder - the roofless version of Audi's radical city car, due to bow in at the 2011 Frankfurt motor show.
There's not much else to say about this Audi: it's the same as the coupe shown earlier this month, but with a low, continuous window area and doors that open diagonally to the top.
Audi Urban Concept Spyder: the lowdown
It's a tiny two-seat runabout powered by two electric motors. How do two people fit into this slip of a car? By sitting in a 1+1 tandem layout, like on the Caparo T1.
The Audi concept is made from a mix of carbonfibre reinforced plastic and aluminium.
The full details will be issued nearer the Frankfurt motor show. Stay tuned for more.
