You probably remember the ungodly power numbers from ABT’s lust-worthy A6 Avant. While we thought those figures were in the upper stratosphere of the car’s tuning potential, German tuner B&B Tuning have shown us that there’s more to be gleaned from the wagon’s beastly V10. Pulling 715 horsepower out of the 5.0-liter mill has put the guys at the top of the RS6 heap and launching the family hauler to 60 in 3.6 seconds. We’re sure there are universal laws being violated as we speak, but who are we to stop ‘em? B&B also offers other levels of tuning for those who don’t enjoy embarrassing Lamborghinis for fun. You can opt for a 650 hp, 670 hp or the full monte. You know what we’d pick. [Motor Authority]
