The Mazda6 is a roomy car now. For all practical purposes, it’s as large as a Toyota Camry inside, with a backseat that has plenty of space for adults and a trunk that’s actually the biggest in its class at 16.6 cubic feet. The rear seatbacks can also be folded forward to dramatically increase cargo space; however, there are no releases within easy reach of the trunk—you’ll need to climb around.
Motor Trend reports that the available "head and legroom" allow "two full-size-adults—or three in a pinch—to travel in real comfort." Road & Track also appreciates the increased volume, stating that the Mazda Mazda6 features a "6-percent-larger passenger compartment, making it the new class leader." Automobile Magazine contends that "whereas the last 6 was at the bottom of its class in interior space, the new one is at the top." In the front seats, ConsumerGuide says there is "ample headroom and legroom for average sized" drivers, while the "6's standard tilt and telescopic steering wheel is a plus" and makes it much easier to find a comfortable driving position.
The trunk of the 2010 Mazda6 is, according to the numbers, the largest in its class, and it’s a very usable shape. Cars.com notes that its 16.6 cubic-foot capacity is "slightly larger than that of the Malibu and Accord." Cars.com further mentions that "all trim levels get 60/40-split folding rear seats with remote capability," but ConsumerGuide finds that those seats are "difficult to fold."
Interior storage also receives a boost with last year’s redesign. ConsumerGuide says that the Mazda Mazda6 "has decent small items storage space including a large glovebox and deep, two-tier center console," but they're disappointed that "there are no rear door pockets."
Materials in the 2010 Mazda6 echo those used on other newer Mazda models like the fashionable Mazda3 and the more luxurious CX-9 utility vehicle—that’s to say, very tasteful and stylish, with a look and feel that’s not opulent, but sporty and upscale. The standard cloth upholstery feels sturdy yet comfortable, while the available leather will help satisfy luxury cravings to a degree. About the only complaint involves the electroluminescent gauges included on uplevel models; on brighter days, they prove hard to read.
Motor Trend appreciates the "inviting balance of textured plastic to soft-touch surfaces," which is "tastefully accented by bright and matte metallic trim." Car and Driver raves about the "excellent graining on the dash and dour panels, finished with a perfect satin sheen," and Automobile Magazine feels that the interior is "of equal or better quality than Mazda's main competitors."
In terms of build quality, AutoWeek reviewers report that the new Mazda Mazda6 "felt solid and looked fit and trim both inside and out."
Road and wind noise are commendably low in the Mazda6; to those who owned or drove the previous-generation 6 that was sold through 2007, it’s a big improvement. ConsumerGuide is pleasantly surprised to find that "the 4-cylinder is nearly silent at cruise," although the "V6's buzz is borderline intrusive during acceleration." Car and Driver also reports that "noises, both road and wind, are dialed way back."
