ABT Sportsline, the tuner, has unveiled the RS6 and RS7 Legacy Edition models, featuring an incredible power output of up to 986 horsepower (equivalent to 1,000 metric hp) and 848 pound-feet (1,150 Newton-meters) of torque. The cost of this package is $218,999 (or 205,000 euros), which includes the installation. However, customers must provide their own vehicle for the modifications.

To achieve its maximum power, these cars must be fueled with 102-octane fuel. If filled with 98-octane gas, the power output decreases to 927 hp (940 metric hp) and 774 lb-ft (1,050 Nm) of torque.
