Spied: The Audi RS7, RS6 Avant spotted with new 4.0L Biturbo TFSI engine

Editor’s Note: We have updated this post with a completely new set of photos that show us much more detail.

For the very first time, both the Audi RS7 and RS6 Avant have been spied spied in the wild, the RS7 is even without any sort of disguise. The RS7 show here is in a beautiful Matte Black paint scheme that looks as menacing as we would expect from the crew at quattro GmbH. If you look closely, the car next to the RS7 is ineed an RS6 Avant in full Camo wrap.

We are very excited to see that Audi is taking the tuning of the Audi RS7 and RS6 to the next level with a highly potent 4.0L Biturbo TFSI engine which is borrowed from the Bentley Continental GT and is believed to be coming with at least 550HP. According to the exif data on the photos, these cars were located in Las Vegas, Nevada and were likely out there for some high temperature testing. We can only hope and dream that this means these car may some day grace the showroooms of US Audi dealers!
