TrueDelta Reviews the Seat Room and Comfort of the 2012 Mercedes-Benz GL

2012 Mercedes-Benz GL Seat Room and Comfort: Pros
YearComment
2013 The Mercedes-Benz GL-Class is just a little longer than the Audi Q7 (201.6 vs. 200.3 inches), and isn't as wide (76.4 vs. 78.1 inches). But the Mercedes is considerably taller (72.8 vs. 68.4 inches) and not nearly as curvy. Which might explain how it is far roomier than the much sleeker Audi. Combined legroom for all three rows is 107.6 inches in the Q7 vs. 113.8 inches in the GL-Class, a large difference. The Q7's space deficit grows the farther back you sit. For adults to even fit in the Audi's third row without extreme discomfort, those in the second row must slide their seats forward to the point that they are themselves short on knee room. While the new GL350's third row sits too low to provide thigh support, it's not nearly as cramped. Further evidence that Audi didn't intend the Q7's third row for frequent use: the second-row seat doesn't do a good job of getting out of the way, making the path in and out of the way-back perhaps the tightest I've experienced. The second-row seat in the GL-Class tips forward to open up a much wider path. If manually tipping the seat is too much of a chore (perhaps because you'e a five-year-old and haven't yet learned to read this), $400 buys a power assist. But even with this option the seat must be manually returned to its upright position, so the point eludes me. see full Mercedes-Benz GL review
