2021 Toyota SiennaAug 27th, 2020
“This is an all-new vehicle from the ground up, including a new chassis platform as well as a new electrical platform,” said Chief Engineer Monte Kaehr. “The development of the fourth-generation Sienna was a huge undertaking but we always worked towards one single mission—to make the best van yet.”
Learning from today’s minivan customers that they do not want to feel like they are driving a bus, the design team took this to heart and thought carefully about how to combine the practical attributes of a minivan with the emotional desire for having a more personalized driving experience.
In addition to exemplary collision protection provided by the TNGA-K Platform, the 2021 Sienna comes standard with second-generation Toyota Safety Sense (TSS 2.0), a comprehensive active safety system that includes:
- Pre-Collision System with Pedestrian Detection/Low Light Detection and Bicycle Detection
- Full-Speed Range Dynamic Radar Cruise Control
- Lane Departure Alert with Lane Trace Assist
- Automatic High Beams
Like all Toyota vehicles built on the new TNGA-K Platform, the 2021 Sienna benefits from a multitude of measures that bring library quiet to the cabin. In particular, Toyota engineers focused on reducing noises in the frequencies where conversation takes place.
Of course, with all the onboard connectivity Sienna offers (seven USB ports, available JBL 1,200-watt amp/12-speaker Premium Audio and 1080p HD rear entertainment system), conversation is just one of the things made better by the quieter cabin.
If interior noise level should rise, say, due to a minor altercation between certain young passengers, Sienna’s unique available Driver Easy Speak is the driver’s best friend. Introduced on the third-generation Sienna, this feature is essentially a built-in PA system that carries the driver’s voice through the audio system’s rear speakers right to the source of the disturbance.
Over the years, the Sienna has augmented its excellent outward visibility and sightlines with technology to see more of what’s behind and around the vehicle. The 2021 model delivers the latest generation of that tech:
- The standard backup camera features projected path, while higher grade models have a wide-angle monitor to show even more of what is behind the vehicle.
- The available digital rear-view mirror functions as a standard mirror most of the time, but if rear-seat passengers or some cargo block the view to the rear, the touch of a switch makes all obstructions disappear, replaced by the camera’s image from behind the vehicle. The digital mirror also integrates a HomeLink® transceiver to conveniently operate garage doors and other compatible devices.
- The available Bird’s Eye View Camera with Perimeter Scan provides a live, 360-degree view to help the driver to see potential obstacles. This is especially critical for seeing children or small animals that might be close to the vehicle. And, Curb View can help prevent scuffing those beautiful 20-inch wheels.
Electronic on-demand All Wheel Drive
Sienna has long offered optional all-wheel drive, and the 2021 model is no exception. The 2021 Sienna is the only vehicle in its segment that combines a hybrid powertrain with AWD, and the system is available on all model grades.
