2010 Initial Quality Study Results
2010 Toyota Sienna

Overview
The Toyota Sienna is a family-oriented minivan with optional seating for up to 8 passengers. The Sienna offers dual sliding doors, standard 6-cylinder power, and front-wheel drive. All-wheel drive, unique in this segment, is optional.
History/Genealogy
Toyota introduced its first minivan in 1984. Bucking conventional wisdom, Toyota mounted the engine in the middle of the chassis (under the driver's seat). Although this design improved handling, it led to unconventional styling and-with only a 4-cylinder engine-the minivan was somewhat underpowered. The second-generation Toyota Previa arrived in 1990. It continued with the mid-engine configuration, but added an all-wheel-drive (AWD) powertrain and a supercharger to boost power (a 6-cylinder engine simply would not fit in the existing engine compartment).In 1998, Toyota switched to a conventional front-engine, front-wheel-drive platform with the introduction of the Sienna minivan. Sharing platforms with the Camry sedan (but still a bit smaller than the competition's offerings), the new model offered a 6-cylinder engine for the first time. This model was followed by the second-generation Sienna in 2004. Again sharing the Toyota Camry platform, the new Sienna was now "full size" with 8-passenger capacity, giving it the ability to compete directly with the offerings from Honda, GM, and Chrysler. In addition to standard V-6 power and available AWD, the Sienna could be optioned with a flat-folding third row, retractable side windows, and voice-activated navigation.
The 2010 Sienna is offered in many trim levels, with up-to-8-passenger seating. Toyota made no significant changes to the 2010 Sienna, as an all-new third-generation model has been introduced for 2011.
