While the Sienna's suspension is tuned toward comfort, the SE trim features improved springs and dampers for better handling that aims to be more like that of a car. The standard 19-inch wheels on the SE trim are a nice complement to that model's privacy glass, roof rails and smoked chrome exterior pieces.
The Sienna is the only vehicle in its class to offer optional all-wheel drive. Toyota's system utilizes a center differential to split power 50/50 between the front and rear wheels under normal driving situations, but transfers more to the wheels that have traction during slippery conditions. Two-wheel-drive Siennas are configured as front-wheel drive.
Safety is an important factor in designing any minivan, and the Sienna comes with a long list of such features. Electronic stability control and anti-lock brakes with brake assist are standard, as are front seat-mounted side airbags and side-curtain bags for all three rows. Driver knee airbags are also included. All-wheel drive models are also fitted with run-flat tires that allow the Sienna to go up to 100 miles at 55 mph once the tire loses air. Blind-spot monitoring is optional on the XLE.
Interior accommodations in the Sienna include three rows of seating and a capacity of either seven or eight passengers. The 8-passenger configuration -- offered on SE, LE and XLE trims -- includes a second-row bench seat that can slide fore and aft. The 7-passenger models substitute two captain's chairs for the bench. Second- and third-row seats are removable to expand cargo space.
L, LE, XLE and Limited trims for the Sienna span a wide range of equipment, depending on whether the buyer wants simple and basic or luxurious. The base L does include most popular equipment such as keyless entry, power windows, locks and mirrors, cruise control, 3-zone climate control, Siri Eyes Free iPhone integration and a 4-speaker CD sound system. At the top of the range, the Limited adds a JBL premium stereo, 18-inch alloy wheels, Smart Key remote keyless system, a power moonroof, heated seats, automatic climate control system, woodgrain interior trim, a parking-assist system and a Bluetooth hands-free calling interface.
Options at the top of the line include a unique dual-view entertainment system that allows rear seat passengers to watch two different programs on one display, navigation satellite radio, HID headlamps, rain-sensing wipers and adaptive cruise control.
