The Audi models that can most reliably fit three car seats are the three-row Q7 and the Q8 e-tron (formerly the e-tron) SUV. For two-row models, the larger sedans like the A6 and A8 can be a tight fit, but it's highly dependent on the specific car seat dimensions and your willingness to use the seat belt installation method for the center position.
The key factor isn't just the car's size, but the configuration of the Lower Anchors and Tethers for Children (LATCH) system. Most vehicles, including Audis, have dedicated LATCH anchors only for the window seats. The center seat often lacks these anchors, meaning you must use the vehicle's seat belt to secure the middle car seat, which is perfectly safe if done correctly. The Audi Q7 is the standout choice because its third row provides the flexibility to seat three children without needing to fit all seats in one row.
Here’s a comparison of key Audi models for this task:
| Audi Model | Body Style | LATCH Anchor Positions (2nd Row) | Realistic 3-Car-Seat Fitment | Key Consideration |
|---|---|---|---|---|
| Q7 | 3-Row SUV | 2 sets (Outboard seats) | Excellent | Use 2nd row outboard seats + 3rd row. Or, two narrow seats outboard and a seat belt-installed seat in the 2nd row center. |
| Q8 e-tron | Midsize SUV | 2 sets (Outboard seats) | Very Good | Wide second-row bench. Requires one seat to be installed with the seat belt in the center. |
| Q5 | Compact SUV | 2 sets (Outboard seats) | Challenging | The second row is narrower. Success depends entirely on using slim-profile car seats. |
| A6 Allroad | Wagon | 2 sets (Outboard seats) | Good | Wagon body style offers more rear headroom than a sedan. Center seat belt installation is key. |
| A8 L | Full-Size Sedan | 2 sets (Outboard seats) | Fair | Legroom is ample, but sedan roof lines can make buckling children in the center difficult. |
The most crucial step is a test fit. Bring your actual car seats to the dealership. Try installing them using both LATCH and the seat belt to see what configuration works best for your specific setup. Focus on "slim" or "three-across" specific car seat models for the best chance of success in two-row vehicles.

We have three kids in car seats and went through this with our Audi. Our Q7 is the only one that works without a major headache. We put the two older ones in the third row and the baby’s rear-facing seat in the second row. Trying to fit three across in our old A4 was a nightmare—it just isn’t wide enough. My advice? If you have three young kids, just get the three-row SUV. It saves your sanity.

Focus on the Q8 e-tron or Q7. The width of the rear bench is critical. Remember, you'll likely be using the seat belt to secure the center car seat, as LATCH anchors are typically only on the sides. Look for car seats marketed as "slim" or "three-across" friendly. The official measurements matter less than a real-world test with your specific seats before you buy.
