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.
