In the minivan world, the 2021 Toyota Sienna is a very big deal. For starters, there aren't a lot of minivan models any more – four in fact – so any completely redesigned version is noteworthy. Yet, this is also the first all-new Sienna in 10 years; a much lengthier gap between generations than usual, and one that resulted in its predecessor getting awfully long in the tooth despite consistent updates. A new Sienna has therefore been overdue, but Toyota at least used the extra years to develop a van that moves the ball far downfield.
What's under a minivan's hood rarely makes headlines, but in this case, it does. Every 2021 Sienna is a hybrid, foregoing the usual V6 and its low-20s-mpg fuel economy in favor of Toyota's familiar gasoline-electric powertrain that returns an EPA-estimated 36 mpg combined. Sure, it's not quite as quick as those V6-powered vans, but we're not sure how much minivan buyers will care about that. The Chrysler Pacifica is the only other minivan available as a hybrid, but that's a plug-in hybrid model that provides some all-electric range and carries a higher initial price tag.
