Which Audi models have the most spacious interiors?

I am looking for an Audi model with a large amount of interior space. I need to comfortably fit four adults in the car with enough legroom for long drives.

The Audi Q7 and Q8 models have the most spacious interiors, with plenty of legroom for both front and back seat passengers. The larger size of these SUVs also allows for ample cargo space.

If you're looking for a smaller Audi option, the A6 and A7 models also have spacious interiors. The A6 has a roomy back seat with adjustable seats for added comfort during long drives.

One unexpected model with a surprisingly spacious interior is the Audi TT. Its clever design allows for a surprisingly roomy cabin, perfect for fitting four adults comfortably.
