What is the best engine size for the 2019 Audi A6?

I am considering buying a 2019 Audi A6 and am wondering about the engine size options. What is the best size for this model?

The best engine size for the 2019 Audi A6 would be the 3.0-Litre V6 engine, as it provides a good balance between power and efficiency.

I would recommend getting the 2.0-Litre inline-four engine for the 2019 Audi A6. It may not have as much horsepower as the V6, but it offers better fuel efficiency.

There is no clear 'best' engine size for the 2019 Audi A6 as it ultimately depends on your personal preferences and driving habits. I suggest test driving both engine options to see which one suits you better.
