"As we gave the A1 that nomenclature there’s clearly room for another product and another concept between the A3," he admitted.
Stadler wouldn’t be drawn on what exactly a new A2 could be, but admitted that it would be an obvious propostion.
"If you don’t have to explain a car like the A2 then it works," he said.
However other insiders have admitted that the A2 is likely to be an ‘E2’: an electric car based on the the A1 but with a unique bodystyle and look.
Stadler also quashed rumours that Audi was planning a car based on the VW Up!, possibly badged A0, saying that there was no possibility of the company slotting in a car under the forthcoming A1 supermini, which will be launched at the Geneva motor show in March.
