With every number from A1 to A8 having already been assigned, Audi is rumored to be working on an A9 to top its ever-expanding range. Earlier reports indicated that the A9 would arrive as a four-door coupe to take on the likes of the Mercedes-Benz CLS. But while a four-door model may be in the cars, the latest word from Autobild is that the A9 will arrive first as a two-door coupe and convertible.

Platform underpinnings are still tipped to be shared with the upcoming Lamborghini Estoque, as well as the next-generation Porsche Panamera, Audi A8 and possibly the next Bentley Continental GT as well. If a four-door model follows, the A9 could follow a similar derivative roll-out scheme as the A5, which came first as a coupe before being turned into the five-door Sport back version. Either way, we suspect it won’t look anything like the rakish A9 concept conceived of by independent designer Daniel Garcia shown above.
