What's the point? The Golf (Plus) already exists in the Audi stable, it's the A3?
What's the point of making it physically bigger to make people think it's bigger in side? The Q7 is a whale of a beast on the outside, but inside it's the opposite! The A2 was well-packaged and Tardis-like.
So - it won't have an alu/carbon chassis, it won't therefore likely have alu/ mixed material body panels, it then more than likely won't feature the very clever flat-floor interior of the original or the concept, and unlikely to have any innovation in drivetrain.
More and more likely that my next car won't be an Audi at this rate.
