New Audi Q7 (2013) to shed weight. But no Audi Q9 planned.

The 2013 Audi Q7 will be much lighter than the current Q7 The Audi Q7 was rather late to the SUV party of the noughties, not hitting the road until 2005. That meant the Q7 had a bit of an edge when it launched, as it was newer than its competition, but it also means the Q7 is still soldiering on when its competition has already launched newer, shinier models. But Audi are working on fixing that, and fixing the biggest criticism of the Q7 in the process – its sheer weight and size.

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.
