2016 Audi TT Roadster Spied Testing

While the Audi TT has only just gone on sale in Europe, the German automaker's engineers are already hard at work on its roofless counterpart.

Seen here at the Nurburgring Nordschliefe circuit, this TT Roadster prototype shows that Audi won't be messing with the topless TT's familiar formula.

The new TT Roadster will continue to be offered as a soft-top, with the roof-up silhouette showing a slightly coupe-like profile instead of the coupe's sleeker fastback shape.
