Interior accommodations in the 2010 BMW 1-Series are what you've come to expect from BMW of late: less austere and more attractive, while remaining easy to use.
Whether as a coupe or convertible, the 1-Series is more of a 2+2 than a vehicle with a full backseat. But in a nod to practicality, the rear seat of the 2010 1-Series includes both a pass-through and 60/40 split-folding access to the trunk. The compact folding mechanism of the convertible's soft top even ensures usable trunk space with the top down.
The BMW 1-Series, as either a coupe or convertible, is designed to seat four. ConsumerGuide points out that the front allows "ample room for adults on comfortable seats." As expected in a car of this size, the rear seat gets mixed reviews. ConsumerGuide reports that the backseat offers "enough headroom and legroom for an average-size adult to sit behind another average-size adult." The reviewer adds a caveat, however, which is that "any front-seater over six-feet tall will delete rear legroom behind them." Additionally, "elbow space is very tight in the coupe and even less in the convertible" for rear occupants. Reviewers at Kelley Blue Book characterize the seating in the back of the BMW 1-Series as "comfortable but cozy."
The coupe versions of the BMW 2010 1-Series have a trunk that "offers a reasonable 10 cubic feet of storage space," according to Kelley Blue Book, and if additional space is needed, "the rear seats can be folded to accommodate larger items." Motor Trend approves of the storage space on the convertible, remarking that "because it's a fabric roof rather than a rigid folder, it doesn't swallow too much trunk space."
Aside from trunk space, there's not much storage room on the 2010 1-Series, as ConsumerGuide notes that "interior storage is limited to a small glovebox and smaller console box, along with a tiny console bin and map pockets."
Most reviewers are impressed with the interior quality of the 1-Series. Kelley Blue Book lauds the fact that the "interior treatment of the 1 Series is anything but cheap." Edmunds says, "Despite being the cheapest BMW sold, the vehicle's interior materials are consistent with its larger and more lavish siblings." Cars.com, however, remarks that on BMWs 2010 1-Series "the leather is less luxurious" and the "plastic also seems to be a lower grade in a few places" compared to the 3- and 5-Series BMWs.
Solid build quality contributes to the low level of ride noise, which ConsumerGuide says is "well checked," and "top down, the convertible requires only slightly raised voices at highway speeds." Motor Trend, however, observes that the convertible top "generates wind noise."
Ride quality on the BMW 2010 1-Series is a function of trim level and options, but there aren't really any surprises here. ConsumerGuide finds that "the tested 128i convertible [rides] surprisingly well, easily soaking up smaller road blemishes and pavement heaves." However, opting for the 135i brings a "sport suspension and 18-inch tires, a combination that reacts much more sharply to bad pavement, yet never feels harsh." Customers should expect that the 135i in full sport mode will feature a rougher ride than the 128i with more comfortable settings.
