Sit behind the wheel of this Unitronic-Tuned C7.5 Audi S6, while I drive up through the snowy mountains of New Hampshire!

We're running Michelin Pilot Sport AS3+ tires, a 93 Octane Unitronic ECU tune, and Unitronic Stage 2 TCU tune.

Let's see how the Michelin's and Quattro All Wheel Drive work on the slippery mountain roads.
