Gallery: The 740 HP ABT RS6-R Share Comments Previous ImageNext ImagePreviousNextView Large Following in the footsteps of last week’s RS7-R, ABT has released photos of its tuning regimen for the RS6 Avant. Making 740 HP and nearly 680 lb-ft of torque, the car is a reminder of the awesome capability of Audi’s 4.0-liter V8. ABT has also taken some time to create a new front lip, a grille add on, rear skirt add-on, side skirt attachments, and fender inserts. All of these parts (and more) are made of carbon. Inside, too, there have been improvements, including a leather-wrapped steering wheel. The RS6-R will be limited to just 125 examples, so exclusivity won’t be an issue.
