Audi is playing its part in saving the wagons by giving the A5 Avant a bigger brother. We mean that in more ways than one since the new A6 Avant ("C9") seems like an upsized version. That's not a bad thing, as both wagons look great, although more variety wouldn't hurt. Curiously, the next-generation A6 debuts strictly as a wagon, but the traditional sedan body style will follow next month. In the meantime, the long-roof model takes the stage.
