2021 Toyota Sienna vs. 2020 Toyota Sienna 

As was stated earlier, the biggest change made to the 2021 version of the Toyota Sienna when it is compared to the 2020 model is physical size. Both model years will be able to hold seven or eight passengers, depending on which trim grade is chosen by the customer. While the 2021 Sienna is smaller than the 2020 model, future owners will still have a lot of room to work with. A 2021 Toyota Sienna will offer almost the same amount of legroom for the driver and front passenger. Second- and third-row passengers will have more legroom in the 2021 Sienna than in the 2020 version. There will be 33.5 cubic-feet of cargo volume behind the third row in the 2021 Sienna. Up to 75.2 cubic-feet and 101 cubic-feet can be made available behind the second and first rows, respectively. This is slightly less than what’s in the 2020 Sienna.

The only story bigger than the physical dimension changes to the 2021 Toyota Sienna is the change made to its standard powertrain. Toyota has decided to eliminate the previously used the V-6 engine which was the standard power plant in the 2020 model. Colonial Toyota customers interested in the 2021 Toyota Sienna will have a 2.5-liter, four-cylinder hybrid engine under the hood that is attached to a continuously variable transmission and it will make up to 245 horsepower. While this is significantly less than the 295-horsepower produced by the V-6 engine employed by the 2020 Sienna, both versions are capable of towing 3,500 pounds. Additionally, both iterations of the Toyota Sienna are available with all-wheel-drive. 

Customers with the 2021 Sienna in their driveway can expect the redesigned platform to record 36 miles per gallon in the city and 36 miles per gallon on the highway when the vehicle is equipped with front-wheel-drive. This is a significant improvement over the 2020 version. Even the all-wheel-drive-equipped models of the 2021 Toyota Sienna will be able to post very similar fuel economy scores.
