The Audi RS5 line-up is set to grow this September at the Frankfurt Motor Show with the arrival of the Sportback version which has just been spotted testing.
Although the prototype is wearing S5 badges, the wheel arch extensions, RS alloys and the RS exhaust pipes are a dead giveaway to their top-spec model.
When the covers do come off, we can expect it to have nearly identical specifications to it’s Coupe sibling although performance may take a fractional knock due to the extra weight of the body.
