While it currently competes with BMW and Mercedes-Benz for supremacy on the premium market, Audi was nowhere near as fancy as a brand some three decades ago. But the Ingolstadt-based firm evolved quite dramatically in the 1990s and 2000s, and it’s now selling a handful of highly appreciated premium vehicles, including the A4, A6, A8, and Q7. However, while Audi joined several new niches in recent years, it still doesn’t have a competitor for the relatively new Mercedes-Benz S-Class Coupe. But this will change soon, as Audi is already working on the A9, a two-door version of the new A8 and its largest, most luxurious coupe yet. Alongisde the A9, Audi is also rumored to have an RS9 model in the works. The latter will compete against the Mercedes-AMG S63 and the recently confirmed BMW M8.
