Yes, a car seat can fit in a Scion FR-S, but it is a challenging and often impractical task. The FR-S is a low-slung, lightweight sports coupe designed for driving enjoyment, not family hauling. While the rear seats are technically present, they are best suited for small packages or occasional use by very small children in car seats. For regular use, especially with rear-facing infant seats, the FR-S is one of the most difficult cars to manage.
The primary challenge is the extremely limited rear-seat legroom and the low roofline, which makes maneuvering a seat into position difficult. The LATCH system (Lower Anchors and Tethers for Children) is present in the FR-S, but accessing the lower anchors requires pushing aside stiff seat cushion material. The tether anchor is typically on the rear shelf.
Here is a comparison of key interior dimensions that impact car seat installation:
| Dimension | Scion FR-S / BRZ (1st Gen) | Typical Compact Sedan (e.g., Honda Civic) | Practical Implication for Car Seat |
|---|---|---|---|
| Rear Legroom | 29.9 inches | 35-38 inches | Driver's seat must be pushed very far forward. |
| Rear Headroom | 36.1 inches | 36-37 inches | Tight vertical space, especially for rear-facing seats. |
| Curb Weight | ~2,800 lbs | ~3,000-3,200 lbs | Lighter car may feel more impacted by the weight of a passenger. |
| Door Opening Size | Narrow and low | Wider and taller | Difficult to angle a bulky car seat through the door. |
For a forward-facing convertible seat, the process is more manageable once the seat is secured. However, for a rear-facing infant carrier, the front passenger seat will likely need to be moved so far forward that it becomes unusable for an adult. If you absolutely must use a car seat in an FR-S, opt for the slimmest, most compact models on the market and be prepared for a daily struggle. This car is not a viable primary vehicle for a family with an infant or toddler.

I tried it once with my nephew's forward-facing seat. It's a real squeeze. You have to be a contortionist to get it clicked into the LATCH anchors behind the seat cushions. Once it's in, there's zero legroom in front of it. Honestly, those back seats are for groceries or a backpack, not a kid. If you need to do this regularly, you'll hate it. It's possible, but it's the opposite of convenient.

As an enthusiast who owns an FR-S, I view the back seats as a convenient place to store my helmet or track tires. The idea of putting a car seat back there is comical. It completely defeats the purpose of the car—adding significant weight in the worst possible place, high up and behind the axle, which hurts handling. If you're at a point in life where a car seat is a priority, this is not the right chassis for you. It's a dedicated sports car, not a compromise vehicle.

From a pure safety and practicality standpoint, the FR-S is not recommended for child transportation. While it can be done, the compromised front passenger space is a concern. In an emergency, a front passenger may not have a safe seating position. The car's stiff suspension also translates road imperfections directly into the cabin, which may not provide the smoothest ride for an infant. For occasional, short trips with a forward-facing seat for a preschooler, it's a workaround. For daily use, a vehicle with a more family-friendly design is a much safer and saner choice.

Look, it fits. But "fit" and "work" are two different things. The real question is about your lifestyle. Is this your only car and you have a newborn? Bad idea. Is it your weekend fun car and you need to occasionally pick up your four-year-old from preschool? That's more feasible. The key is choosing the right seat. You need to research models known for being compact, like the Diono Radian 3R. Measure twice, buy once. Be prepared for it to be a major hassle, and accept that you're using a tool for a job it was never designed to do.
