ABT's Devilish Tuning Takes New RS6 to 666 HP [Video]
When the RS6 left the factory, it did so with a setup that was already impressive, 560 HP (412 kW) and 700 Nm of torque. But the ECU power kit from ABT pushes that to 666 HP (490 kW) and 830 Nm (612 lb-ft) of torque - an increase of 106 HP (78 kW) and 130 Nm (96 lb-ft) of torque.
As a result of this boost in power, the RS6 Avant reaches 100 km/h in 3.9 seconds and tops out at 300 km/h (186 mph).
No other details were released, not even pictures, but it's enough to get us dreaming of RS6 ownership. After all, the car now has more power than a Murcielago.
