The 2010 Sienna includes a very spacious interior with a third row of seats that fold neatly into a well, allowing plenty of flat, low space for cargo while maintaining seating for five. Note, however, that the top-of-the-line 2010 Toyota Sienna XLE and XLE Limited models get twin captain’s chairs in the second row instead of the three-place bench seat. Dual sliding doors and folding third-row seats are included on all models. A higher trim level gives you power sliding doors, a power folding third row, and a power rear tailgate.
Up front, ConsumerGuide reports “room aplenty on comfortable seats” and “no-strain entry and exit.” Furthermore, they appreciate that “standard seat and steering-wheel adjustments cater to most any size driver.” One of Car and Driver’s testers note “butt burn” from the driver's seat resulting from a shape that forces a thin person's weight uncomfortably forward on the cushion.
Edmunds finds that in the second and third row, the Sienna is “one of the roomiest minivans available,” and in Car and Driver’s minivan comparison, the Sienna’s optional “second-row captain's chairs were rated highest for comfort.” Kelley Blue Book notes that “the Sienna's seats take full advantage of the van's roomy interior, with wide seat bottoms as well as firm back rests.” “Bench or buckets, the second-row seats seem long-haul comfortable,” comments ConsumerGuide. The Sienna is one of the few minivans to offer true eight-passenger capacity.
In case you need more space, the second row of seats can fold away as well, allowing you to carry things as big as 4x8 sheets of plywood. Kelley Blue Book elucidates, “the Sienna's rear seat can fold flush into the floor and features a 60/40 split.” However, its removable seats are a bit heavier and more difficult to manage than in some of its rivals.
The Sienna impresses all-around interior-wise, thanks to quality fit and finish. The only noticeable complaint might be that the interior materials and appointments feel a bit less refined compared to those of its competitors, though overall quality is still commendable. “The gauges are clear,” says ConsumerGuide, “and minor controls are guess-free.” Thoughtful features abound, such as “door panels … scooped out to give exceptionally good elbow space” (Car and Driver). “The various controls are simple to use, storage space is plentiful and the seats are plush,” notes Edmunds. And the ever-critical ConsumerGuide mentions “the cabin benefits from high-grade plastics, but some of our testers say the colors and fabrics are drab.”
Perhaps making up for its lack of athletic moves, Car and Driver claims that in comparison with the others makes in this segment, “what you get instead of confident handling is a soft, quiet ride that makes the others seem a bit rude.” Edmunds also notes the “softly tuned suspension,” and ConsumerGuide finds the van to be “comfortably composed. Large humps and dips induce some body bounce, but the suspension irons out most rough pavement.”
The Sienna’s noise levels, according to ConsumerGuide, are “at least equal to the class-topping Honda and Chrysler/Dodge minivans” and that “the main noise source is moderate coarse-pavement tire thrum.”
