Yes, fitting three car seats across the Audi Q5's rear seat is technically possible but extremely challenging and not recommended for regular use. The success hinges almost entirely on selecting specific, narrow car seat models and using the vehicle's seat belt system instead of the lower LATCH anchors. The Q5 is classified as a compact luxury SUV, and its rear bench, while comfortable for two adults, is simply not wide enough to accommodate three child safety seats safely and conveniently.
The primary obstacle is the lower LATCH anchor system. The Q5 is equipped with two full sets of LATCH anchors in the outboard seating positions (driver-side and passenger-side rear). The center seat position typically only has a top tether anchor; it lacks dedicated lower anchors. This means you can only securely install two car seats using the preferred LATCH system. For a three-across configuration, you must use the vehicle's seat belt to install at least one, if not all three, car seats. A proper seat belt installation is equally safe when done correctly, but it can be more difficult to achieve a tight, non-moving fit.
The key is choosing the right car seats. You'll need to look for models known for their narrow profiles. Infant seats tend to be the widest, so your best bet is a combination of narrow convertible or booster seats. The physical width of the rear seat cushion is the limiting factor, and even with narrow seats, the install will be tight.
| Car Seat Model Type | Approximate Width | Suitability for 3-Across in Q5 |
|---|
| Standard Infant Seat | ~17-19 inches | Poor - Too wide for a viable configuration. |
| Standard Convertible Seat | ~18-20 inches | Poor - Unlikely to fit three across. |
| Narrow-Profile Convertible Seat | ~15-17 inches | Good - The only realistic option (e.g., Diono Radian 3RXT). |
| Backless Booster Seat | ~14-16 inches | Good - But only for children who have outgrown a 5-point harness. |
| Audi Q5 Rear Seat Width | ~52 inches | The physical constraint that must accommodate three seats. |
Ultimately, while it can be done as a temporary solution or for occasional carpools, the Q5 is not an ideal vehicle for a family that requires three full-time car seats. The process is frustrating, the seats will be crammed tightly together, and accessing the center seat buckle can be very difficult. If you frequently transport three children in car seats, a midsize or full-size SUV with a wider bench or a third row is a more practical long-term choice.
