The Toyota Sienna will likely see a redesign for 2021. When it arrives, the long-running nameplate is expected to move to the automaker's modular TNGA platform. No official specs or details have been released just yet, but early fleet production data indicates Toyota will begin taking orders sometime in July of 2020. This could point to a release date in late summer or early fall.
The current Sienna was introduced back in 2004 and has benefited from incremental updates like tweaks in appearance and important standard features like automatic emergency braking. At the moment, the Sienna remains the only minivan available with all-wheel-drive, a potential selling point for buyers requiring that capability for driving in inclement weather.
That said, the minivan segment has gotten smaller over the past decade as shoppers flock to a growing segment of three-row crossover SUVs. Fortunately, those looking for the utility of a minivan should be aware that Toyota has signaled no intention to abandon the segment. This page will be updated based on the latest information.
