Audi has issued pictures of the Project Rosemayer supercar that has until now been hidden away at VW group's automotive theme park - Autostadt - in Wolfsburg, Germany.
Project Rosemayer is a pure concept, says Audi, and is not ready to be driven. 'It has not been created in anticipation of any production vehicle,' said a spokesman. 'Rather, it shows the potential of the Audi brand.'
Visitors to the Audi pavilion at Autostadt have been treated to brief glimpses of Project Rosemayer, but until now no official details had been published.
The supercar is designed to take a 16-cylinder mid-mounted engine mated to Audi's quattro permanent four-wheel-drive system. It's also inspired by the German manufacturer's past, recalling the record breaking Auto Union racing cars of the 1930s.
Bernd Rosemayer - after whom the car is named - was among the most successful Auto Union drivers of the period.
'The outlines, with its domed roof, semi-circular wheel arch cutouts and high waistline, all echo Audi's current design philosophy,' said the spokesman. 'It spans the gap between past and present and continues the line into the future of the brand.'
Inside, Project Rosemayer uses brushed aluminum, carbon fiber and leather.
