​​How Do Child Seats Fit in the Cab of the 2026 GMC Sierra EV?​ 

The designers and engineers at GMC know that their pickup trucks are now used as family transportation, not just in Texas, but across this country. A lot of thought has gone into ensuring that every type of child seat fits in the cab of any of our pickup trucks. That includes the 2026 Sierra EV.  

Our battery-electric full-sized pickup truck has an accommodating, large cabin designed to carry up to five people. Available in Elevation, AT4, and Denali, each interior environment not only provides comfort for everyone on board but also offers the flexibility you need to carry out your daily routine on the road. That includes making sure your child is safe inside when using a car seat or a booster seat.   

When it comes to fitting child seats inside the 2026 Sierra EV’s, who do you turn to make sure they can work with your children? The experts at Cars.com test vehicles to see whether they are truly family-friendly for you to bring your little ones along for the ride.  

Their Car Seat Checks use four types of child seats – including infant, booster, front-facing, and rear-facing convertible seats. They also examine how these seats are attached via the latch systems installed in the 2026 Sierra EV. Each category of the Car Seat Check is assigned a letter grade based on testing of the child seat, latching, and overall safety with the seat fully installed.  

To do so, Cars.com goes the extra mile by testing car seat fitment in each vehicle. The driver’s seat is adjusted for a six-foot person, while the front passenger seat is moved up slightly. In the 2026 Sierra EV, they are focusing on the rear seat for installation, access, and overall seat comfort. The ultimate goal is to ensure the rear seat fits all three child seats without any issues.  

The first result is that three child seats can fit in the rear seats of the 2026 Sierra EV. The width of the cabin is a huge advantage in doing so. Accessing the latches was given a high mark from Cars.com. The two sets of lower seat anchors are easily marked and accessible. The infant and rear-facing convertible seats fit very well inside the 2026 Sierra EV, earning high marks from the Car Seat Check testers.  

Keeping your family safe should always be a priority, especially for your littlest ones.
