Matt Farah has reviewed some highly modified vehicles in the past. In a recent "One Take" video, Farah was handed the key fob to a modified Audi S6 sedan. The 2015 S6 is no slouch with 420 hp and 406 ft-lb of torque from a twin-turbo 4.0-liter V8. However, because the engine has turbos it is the perfect candidate for a tuning boost. The car that Farah drove has been tuned to produce 520 horsepower. This is a huge increase over stock. The RS6 Avant has 560 hp, but is unavailable if you live in the US because apparently we all hate wagons.

If you don't want to spend the extra money on the RS7, this may be a nice alternative. Farah is quick to question whether the seven-speed dual clutch in the S6 can handle the extra power. Audi claimed that that was the reason the RS7 comes with an eight-speed automatic instead. Check out Farah's jaunt with the modified S7 here.
