When considering a spacious family vehicle, the Toyota Sienna, often categorized as a large SUV alternative due to its size and functionality, comes into focus. A common point of discussion among potential buyers revolves around comparing older and newer generations, particularly concerning cargo space and safety features. Let’s delve into a factual comparison between the 3rd and 4th generation Toyota Sienna models.
A point frequently raised is the seemingly larger cargo space in the 3rd generation Sienna, often cited at 150 cubic feet compared to the 4th generation’s 101 cubic feet. However, this comparison is misleading. The 3rd generation’s measurement includes space with the middle row seats completely removed, a configuration not factored into the 4th generation’s figures because its second-row seats are not designed for removal. In practical terms, the usable interior dimensions are not drastically different between the two models.
Where a significant difference emerges is in safety ratings. The Insurance Institute for Highway Safety (IIHS) crash test evaluations reveal notable improvements in the 4th generation Sienna. Specifically, the 2016-2020 (3rd generation) Sienna received a “Marginal” rating for the small overlap front passenger-side test and “Acceptable” for the driver-side. In stark contrast, the 2021 and newer (4th generation) Sienna achieved “Good” ratings in both these critical small overlap front crash tests, matching the “Good” scores of the 3rd generation in moderate overlap front, side crash, roof strength, and head restraint tests.
Further examination of detailed crash test results for the 2011-2020 Toyota Sienna models highlights areas of concern in frontal crash protection.
Conversely, the 4th generation Toyota Sienna demonstrates consistently high safety performance across the board in IIHS testing.
While detailed driver and passenger-specific breakdowns are more readily available for the newer 4th generation models, all assessed safety aspects for both driver and front passenger in the 4th generation Sienna earned the top “Good” rating. Considering these objective safety evaluations from IIHS, the 4th generation Toyota Sienna presents a clear advantage in occupant protection compared to its 3rd generation predecessor, particularly in demanding small overlap frontal crash scenarios. For families prioritizing safety in a large SUV-sized vehicle, the advancements in the newer Sienna generation are a significant factor to consider.
