The 2023 Chevrolet Suburban is larger than the standard 2023 Ford Expedition, this is because the Suburban is more comparable to the Expedition Max in size and the Chevrolet Tahoe is more akin to the Expedition in size. However even when compared to the Suburban the Expedition prioritizes a few different aspects of travel over the other.
The Expedition focuses on leg room and space, and your rear seat passengers will be extremely grateful for this, adults even feel comfortable in the rear seat. The Suburban prioritizes cargo space, so the Suburban has about 10 more cubic feet than the Expedition. If you are looking for a Ford that has more comparable space to the Suburban, then you may want to spring for the extra cost of the Max, which is about $2,000 of an add-on price to the standard trim.
