  • All-Wheel Drive
  • New headlamp design
  • Top view backup camera system

The 2017 4th generation S6 is the same size as the 2020, though it doesn’t have a touch screen dash or some of the newer driver safety assistance features. You will save a substantial amount of money, though, with an average MSRP of $81,499. That means buying a 2017 Audi S6 will save you around $36,192 – that’s a hard-to-turn-down 42% discount.

The main things you’ll have that are different than the 2020:

  • Twin Turbo V8 engine with 450 HP
  • Seven speed transmission
  • Navigation system on a the pop-up non-touch screen
  • CPO with 300 plus-point inspection on 5 model years or newer/less than 60,000 miles
  • A mildly different design


Some vehicles can lose 10-15% of their value just by being driven off the lot. Here are the fastest-depreciating cars to avoid.
