670 HP Modified Audi S6 With Unitronic Stage 2 Tune

This isn’t your typical Audi!

Would you assume this beautiful modified 2017 Audi S6 puts out a whopping 670 horsepower and 708+ lb-ft of torque? Probably not – there isn’t too much that gives it away visually making this the ultimate sleeper luxury sedan!

From the factory, this S6 makes 450 hp & 406 lb-ft of torque which are still very respectable performance figures, but the owner of this Audi wanted to take things a bit further!

Our team at the August Garage performed several upgrades to get this car to nearly 700 horsepower.

Installed Upgrades:

– Fi Exhaust downpipes
– Upgraded CTS Turbo intercooler
– Unitronic Stage 2+ ECU and Stage 2 TCU tunes
– RS7 turbos
– Custom exhaust work
