Intriguingly, Keogh also mentioned that the German performance division is also bringing a top secret RS model to the US. "We have one other surprise we're working on, but I'll hold that one," he teased. "There's a cool European model that we haven't brought in yet, and it has been the number 1 car on my list. So maybe we'll get it." Could this mean we'll see the glorious RS4 Avant stateside? Quite possibly, but we have a feeling it will remain forbidden fruit. We'd love to be proven wrong though, because America is in short supply of fast German wagons right now. Alternatively, there's a rumor that Audi is developing an RS Q5 that utilizes the RS5's 2.9-liter biturbo V6 with 444-hp and 443 lb-ft of torque.
