Which is bigger, X7 or GLS?
In the second row, the gls offers a solid four inches more leg room. Perhaps because of these impressive passenger capacity figures, it trails the x7 in terms of cargo area. A new bmw x7 can offer 90. Gls has 84. In terms of overall size, the 2023 mercedes-benz gls is larger than the 2023 audi q7. The gls has a longer wheelbase and overall length, which translates to more interior space for passengers and cargo.
