3.0T is a powerful and responsive platform when combined with the transmission. Plenty of power when needed. Quattro model is fun to drive in the canyons. Options in my vehicle are well thought out and easy to use. Quality interior craftsmanship are exactly why I picked an Audi! New my Audi app on my phone is a bit frustrating.

Audi will always be the first brand of cars I research or investigate. I'm sold on the brand.

The A6 is a top notch mid level luxury vehicle with the right amount of timeless style, comfort, surprising power with unexpected great fuel economy. You will be spoiled by the quietness of the ride.

Very happy so far! Used to own a BMW 320i before my Subaru Legacy. Got the Subaru for the all wheel drive. Love the combination of security from the all wheel drive and the fun acceleration and performance in A6!
