How Do Car Seats Fit in a 2019 Infiniti Q50?

Editor’s note: This Car Seat Check was written in January 2018 about the 2018 Infiniti Q50 sedan. Little of substance has changed with this year’s model. To see what’s new for 2019, click here, or check out a side-by-side comparison of the two model years.

Infiniti refreshed its Q50 luxury sports sedan for 2018, but the changes are subtle. Like the previous model, the Q50 comes with turbocharged four- and six-cylinder engines, and much of the interior also carries over to the 2018 model year. In back, there’s ample room for two car seats, but watch out for the middle spot’s floor hump, which makes the three-position backseat only hospitable for two passengers.

How many car seats fit in the second row? Two

Solid

  • Latch, grade A: Two sets of lower anchors sit in slits in the leather; they’re easy to access. Three top tether anchors sit on the rear shelf under hinged plastic covers.
  • Rear-facing convertible, grade A: This seat was easy to install and the front passenger had enough legroom.
  • Forward-facing convertible, grade A: After removing the head restraint, this seat fit well.
  • Booster, grade A: After removing the head restraint, this seat fit well. The buckles are on stable bases, which should make it easier for kids to buckle up independently.

So-So

  • Infant seat, grade B: The seat was easy to install, and our 5-foot, 6-inch-tall rear passenger had just enough room; taller passengers will need more.

Skip It

  • None

Grading Scale

Solid indicates an A grade for optimum ease of use and fit. So-So indicates B or C grades for one to two ease-of-use or fit issues. Skip It indicates D or F grades.

B: One room, fit or connection issue. Some problems accessing third row when available.

C: Marginal room plus one fit or connection issue. Difficult to access third row when available.

D: Insufficient room, plus multiple fit or connection issues.

About Cars.com’s Car Seat Checks

Editors Jennifer Geiger, Jennifer Newman and Matt Schmitz are certified child safety seat installation technicians.

For the Car Seat Check, we use a Graco SnugRide Classic Connect 30 infant-safety seat, a Britax Marathon convertible seat and Graco TurboBooster seat. The front seats are adjusted for a 6-foot driver and a shorter passenger. The three child seats are installed in the second row. The booster seat sits behind the driver’s seat, and the infant and convertible seats are installed behind the front passenger seat.

We also install the forward-facing convertible in the second row’s middle seat with the booster and infant seat in the outboard seats to see if three car seats will fit; a child sitting in the booster seat must be able to reach the seat belt buckle. If there’s a third row, we install the booster seat and a forward-facing convertible. Learn more about how we conduct our Car Seat Checks.

Parents should also remember that they can use the Latch system or a seat belt to install a car seat, and that Latch anchors have a weight limit of 65 pounds, including the weight of the child and the weight of the seat itself.
