At this point, nobody really knows what the upcoming Audi A6 will look like when it arrives and Audi has made it clear that they plan to keep the public away from the vehicle until they are ready.
However, they did add that those looking for clues as to how the Audi A7 could look like when it arrives might want to check out the Audi A7 Sportback model. We know that the Audi A7 Sportback was fitted with a few new features including the 12.3-inch digital instrument cluster, new interior layout, and a few new tech so we are expecting to see the same in the Audi A6.
The A7 was also powered by a 3.0-liter TFSI V6 engine which offered about 340PS and 500Nm of torque. We do not know if the A6 will be offering the same kind of performance so we will have to wait and see.
At this point, most people believe that the Audi A6 will only make its debut at the Geneva Motor Show but others think it might be earlier than that.
