Audi readies flagship Sport Quattro concept for Frankfurt

Audi will unveil its new Sport Quattro concept at next month's Frankfurt motor show, previewed in a number of sketches.

We first saw the Quattro concept back in 2010 at the Paris motor show and three years later the carmaker has produced another iteration, a 2+2 coupé, that measures in at 4,699mm – 419mm longer than the Quattro concept (4,280mm).

From what the sketches show, the Sport Quattro retains the chunky C-pillar of the 2010 Quattro concept, the 1984 Sport Quattro and the original Ur-Quattro models, while the four headlamp units are another nod to the original.

Full specifications and details haven't been released yet but given the number of sketches revealed more information can't be far away.
