According to these latest renderings, the A5 Sportback will feature a five-door configuration but will be much sleeker than traditional Audi Avant wagons. The design appears almost like a four-door coupe but the roomy cabin, tall profile, and sloping hatchback style rear-door ensures the Sportback sits in its own niche.
The base model will remain FWD but AWD variants will feature the latest quattro torque vectoring systems, which distribute drive individually between each axle and between the rear wheels for improved traction and stability. Power will come from the same engines used in the regular A5 lineup, with a 4.2L FSI V8 expected to appear in a range-topping RS5 model.
