History/Overview
The Sienna is Toyota’s long-running minivan model, introduced in the late 1990s to replace the quirky but cool Previa. For 2021, the Sienna is all-new and enters its fourth generation with fresh styling and an all-hybrid lineup, making it the first-ever minivan in North America with conventional (non-plug-in) hybrid power.
