The 2021 Toyota Sienna has recently been caught for the first time by a spy photographer’s camera on its public road testing. Looking at the spy shots, this prototype version underwent testing in the current Sienna body which received several important modifications on its exterior design. This Japanese-based car manufacturer is currently working hard in order to carry out the initial development for the next-generation 2021 Toyota Sienna. This minivan will most likely get a full redesign for the 2021 model year.
As a reminder, the third-generation Toyota Sienna minivan was introduced for the first time at the Los Angeles Auto Show back in December 2009 and went on sale at American dealers in February 2010 as a 2011 model year. Then in 2015, Toyota provided minor refreshment on this five-door minivan with new taillights and new interior design. Three years later, the mild-facelifted Sienna hit the U.S. market with some minor changes such as the new front grille design flanked by restyled headlights, new side skirts, and standard Safety Sense. So it’s been a very long time that the Sienna Minivan didn’t get a significant changes and total redesign since the third-generation model was launched in 2010.
Toyota is rumored to be making some important modifications to the 2021 Toyota Sienna, including redesigns outside and inside. This new minivan will most likely also ride on the Toyota TNGA platform (longer-version). That means the Japanese automaker is planning to expand the use of TNGA platform across its model lineup. However, the upcoming Sienna seems to use a chassis that doesn’t match the body, marked with a wheel that protrudes outside the wheel arch. Although it’s also possible that this minivan will have a longer wheelbase, and a stretched rear overhang.
Apart from that, the 2021 Toyota Sienna will certainly have a larger size than the previous model and it will get a modified body panel used by the Sienna prototype version during the road test. As a large minivan, the next-gen Sienna will offer spacious interior space, and will be superior in terms of interior space and utilities. Other changes were reflected in the side mirror which had also been moved to the door, not the A-pillar. But the interior now has a bus-like dashboard look and center stack.
The fourth-generation Sienna is likely to be offered with a new hybrid powertrain with 8-speed automatic gearbox, although Toyota hasn’t yet provided an official statement on this matter. However, all Toyota cars that have switched to the TNGA platform are claimed to be much sharper and smoother to drive than the previous generation models. Since the redesigned Sienna will be based on the TNGA platform, it must offer a better level of rigidity and less weight. The current 2020 Toyota Sienna is powered by a 3.5-liter V6 Dual VVT-i engine paired to an 8-speed Electronically controlled automatic transmission with intelligence (ECT-i), which is claimed to be capable of producing up to 296 horsepower at 6,600 rpm and 263 lb-ft of torque at 4,700 rpm.
The scheduled release date is unknown, but the 2021 Toyota Sienna is expected to reach U.S. showrooms at some point next year. While pricing are expected not to rise much from the current model price which starts at the base MSRP of $31,415. Lastly, the next-gen 2021 Toyota Sienna is set to compete with several of its main competitors in the minivan segment, including the Chrysler Pacifica, Dodge Grand Caravan, Honda Odyssey, and Kia Sedona.
