Platform Heritage

The Toyota Sienna is a minivan manufactured and marketed by Toyota primarily for the North American market. It is named for the Italian city of Siena, in the region of Tuscany. It replaced the first generation Previa van, and the Toyota Camry wagon in 1997 (for the 1998 model year) with a more conventional front-wheel drive layout and shares a heavily revised platform with the Camry. Both the Previa and original Sienna were smaller than the other minivans they competed against, but a redesign in 2003 (for the 2004 model year) increased the dimensions to match those of its competitors. It was redesigned again in 2010 (for the 2011 model year). The third generation Sienna went on sale in the United States in February 2010 and is the first Sienna to ever receive a "Top Safety Pick" award from the Insurance Institute for Highway Safety. A 2020 redesign (for the 2021 model year) saw the Sienna becoming a hybrid vehicle for its fourth generation. While previous generations of the Sienna were exported to select Asian and European markets, the fourth generation is the first to be produced outside of the United States as Chinese production commenced in July 2021 by two Toyota joint ventures. In China, it is also marketed as the Toyota Granvia. Following the discontinuation of General Motors' all-wheel drive minivans in 2006, the Sienna was the only minivan in its class offered with AWD in North America until the 2021 Chrysler Pacifica was introduced with an AWD option in 2020. The Sienna is not made in right-hand drive configuration and is not sold in right-hand drive markets. The market segment in many of these markets is occupied by the Alphard/Vellfire and the HiAce/Granvia. As of the fourth generation, introduced in 2020, the Sienna is built on Toyota's TNGA-K platform, which it shares with most of Toyota's other large MPVs and crossovers.
