What level of horsepower does the Audi A7 have?

I've been looking at the Audi A7 as a potential car to buy and I'm curious about its performance. Can anybody tell me how much horsepower it has?

The Audi A7 has a range of horsepower options, with the base model starting at 248 horsepower and the highest trim level reaching up to 591 horsepower.

I've been driving an Audi A7 for the past year and I have to say, the 335 horsepower in the mid-level trim is more than enough for daily driving.
