Prepare to downsize your life if you upgrade to the latest 2010 Z4. BMW's penned a cabin that's not very spacious-in fact, it's just adequate for most adults.
It is larger than before, however. Cars.com reviewers find that the "two-seat interior offers noticeably more headroom and legroom than before," with Motor Trend measuring "0.2 in. more headroom, 0.79 in. more shoulder room and 1.69 in. more elbowroom." It may not sound like much, but Car and Driver says that the "roomier, more comfortable interior" helps make the BMW Z4 "an everyday-capable roadster." The 2010 BMW Z4's interior size is generous enough that one Autoblog reviewer claims his "six-foot two-inch frame fit comfortably" inside the cockpit, which offers legroom that is "nearly identical to the Porsche Boxster, but the Z4 offers a bit more shoulder room." Taller drivers will have to slouch to see stoplights from behind the low windshield header. Car and Driver observes "the standard leather seats are treated with the hot-pants-friendly Sun Reflective Technology (also applied to the steering wheel), which keeps the surfaces cool to cut back on any skin scorching on a hot day."
What it lacks in interior space, it makes up for in storage. Cars.com observes that, compared to the previous BMW Z4, there are "more storage options-albeit few compared to a conventional luxury sedan or coupe." There's a small cargo shelf behind the seats, a low cargo net to trap objects nearby, a center console tray, and clamshell door pockets. A cold-weather package packs on seatback netting, luggage straps, and a storage box at the bulkhead. Edmunds adds that interior storage includes a "small storage area behind the seats that works well for purses or backpacks as well as a moderately sized pass-through" into the trunk. The trunk space is big enough for a couple of carry-on suitcases, plus a camera bag or several duffel bags, but as Edmunds notes, trunk size drops from "a respectable 11 cubic feet with the top up" to just "6 with the top down." Jalopnik calls the six cubic feet "still-very-useful," though.
Aside from a sharp edge or two, the 2010 Z4 wears quite nice interior trim in aluminum, ash, leather and metallic-painted plastic, with an extended-leather option that hides the dash, door caps, and visors. Assembly quality and finish on TheCarConnection.com's test vehicles are high. Edmunds raves that the "cabin is...more elegant than it used to be, with better materials and greater attention to detail." Jalopnik reports "the fit and finish and quality of materials is far beyond that of the old Z4" and is now "on par with the 3- and 5-Series." The Z4 also has low wind buffeting with the top down and windows raised. With the top up, you can carry on a quiet conversation at 80 mph-which wasn't possible in the previous Z4. Jalopnik says it has "all the refinement of a coupe-conversation is easy even close to the vehicle's top speed-without the traditional downsides of a folding hard top." Car and Driver believes "BMW's claim that the aluminum roof is quieter than a softtop," while Autoblog states that, "even with all of the windows down, and without a wind blocker between the seats, air management is acceptable."
