Slightly longer, wider, and taller than in the first generation, this second-edition Mercedes GL Class gets a little better on making almost all of its vast space to people and cargo.
By the numbers, the 2013 GL Class is 202.6 inches overall, with a 121.1-inch wheelbase. It sits 72.8 inches tall, and 84.3 inches wide. That makes it about an inch longer and an inch wider than before, and a half-inch taller--measurable differences, but given the GL's size, not dramatic ones.
The GL's front seats are fine, and don't require too much of a step up to access. The basic functionality is eight-way power adjustments; they can be optioned up with 10-way power controls, ventilation, heating, and multi-contour control, which adds massaging and adjustable thigh and thorax support, along with four modes of on-the-go shiatsu, everything from "slow" to "fast and vigorous."
In the second row, there's a bit of innovation that doesn't affect the generous head and leg room. These second-row seats benefit from wider door cuts, which makes it easier to get in, but they also have a new Easy-Entry feature--either a manual handle or a power actuation, that flips and folds them forward for superior access to the third-row seats. The power controls also slide the front seats forward to accommodate the folded second-row seats, a nice touch--but the sounds of the motors moving the seats aren't the most precise ones we've heard in a Mercedes.
The third-row seats are split 50/50, and all models have power-fold ability, so the bench seat can be stowed or used for passengers. Even adults will fit back here, better than in most full-size utes.
Folding the seats in various ways opens up the GL's cargo space to cavernous proportions. With the third row up, there's 16 cubic feet of space; with the third-row seats flipped forward, the GL has 49.4 cubic feet of storage space. With the second row folded forward, it has 93.8 cubic feet of room--an immense amount of space, if not quite so much as a full-size GM SUV.
