Okay, so yes, the Mercedes-Benz GLE-Class has more maximum cargo space overall. You'll need to lower the SUV’s rear bench to expand the hold from 33.3 cubic feet to 74.9. But the E450 Wagon has more space with the second row of seats in place, at 35 cubes.

Dropping the rear seats expands the cargo area to 64 cubic feet, which is quite a bit less than the GLE, but we'll take more volume with max passengers than more space but only with a pair of seats.
