Passenger & boot space
How it copes with people and clutter
The RS3 is based on the A3, so if you want lots of detail about how much space there is for passengers in each body style, visit our detailed reviews of the Audi A3 Sportback or Audi A3 Saloon.
In short, you get rear doors on all RS3s to make it easy for people to get into the back. Once inside, those passengers will find a similar amount of room as they would in the Mercedes AMG A45 or Mercedes AMG CLA 45. If you're planning to put tall people in the back, it's worth noting that the RS3 Sportback has slightly more head room than the Saloon.
