While all its oddness might lead you to expect otherwise, the X6 turns out to be an incredibly useful and practical vehicle. The fuel economy was pretty good, at around 25-26 miles per gallon. Normally, during the course of the week, I have to fill up a car’s fuel tank twice: The X6 managed to handle gas well enough that I only needed one trip to the pump. It’s surprisingly efficient, too: The rear-liftback hatch was easy and convenient to operate, and even with the dramatically slanted roofline, the storage space out back is downright cavernous.
You may sacrifice a little bit of capacity in opting for the coupe-shape, but practically, it isn’t much. Numbers wise, the X6 has a maximum storage capacity of 59.6 cubic feet. Comparatively, the X5 has a maximum storage capacity of 72.3 cubic feet. Don’t get me wrong. It makes some compromises for the sake of style, but not in a way that would negatively affect most people’s well-being. It’s not hostile design. It’s just weird.
