The Sienna has remained virtually unchanged in the six years it's been on the market. This is telling in terms of its rather dull design inside and out, especially when compared to its newer, more stylish competitors. In some ways, the simple one-box profile is dictated by the requirements of carrying as much as possible, be it passengers or cargo, coupled with fulfilling safety and fuel economy needs.
As can be expected of a minivan, the design of the 2010 Toyota Sienna is not something that most automotive writers rave about. Road & Track half-heartedly classifies it and other minivans as “family cartons,” and MyRide.com, the biggest fan of its lines, finds “the basic shape of the Sienna appealing,” though they cite its “sneering grille work and those big headlights” as the features that create the strongest impression. Kelley Blue Book offers mild praise, describing the Sienna as “smartly styled,” but admits that this generation of the van, now in its sixth year, “offers nothing radical in the way of exterior features or design.”
Inside, the Sienna isn't going to set any pulses racing, but the simplicity wins over some reviewers. Edmunds reports that “the Sienna’s spacious cabin is handsomely fitted.” MyRide.com claims the “Sienna driver sits before a smooth, organic dashboard, with a prominent if slightly awkward center stack.” They like its standard trim with its “dark, lacquered-look plastic,” but are less favorable of the faux wood on the XLE and limited, which “looks tacked on.”
