We've known for a while that Audi is working on a new RS7 Sportback, which will rival the new BMW M5 and Mercedes E63 AMG. The new RS7 will boast over 600 horsepower from a 4.0-liter twin-turbo V8 shared with the Porsche Panamera, though some rumors have pointed towards a hybrid drivetrain borrowed from the Panamera Turbo S E-Hybrid.
Now, an inside source at Audi has told us the next-generation RS7 will be joined by a more practical sibling, the RS6 Avant. Our source spoke to two Audi USA Executives, who confirmed that both the A6 and RS6 Avant models will be sold in the US market by 2020. If this information is accurate, our prayers for a fast Audi wagon in the US will finally be answered, hallelujah!
