This a sketch of an Audi concept called Prologue which suggests the premium brand is about to get involved in the space now led by Mercedes-Benz CLS Shooting Brake, writes Brian Byrne.
The concept itself will feature at the Geneva Motor Show in March, and follows the reveal of a Prologue Coupe at the Los Angeles Auto Show last November.
The concept will also show design details of next versions of the A6, A7 and A8 models.
