2024 Toyota Sienna Hybrid Sneak Peek: Potential Features & Upgrades [Update]

  • Will be the fourth model year of the fourth-gen Toyota Sienna
  • We expect it to have the same design and interior
  • Could have enhanced safety with a new version of Toyota Safety Sense (TSS)
  • Expected to be launched in Fall 2023

Update: ‘Sales’ section updated.

The fourth-gen Toyota Sienna, the Japanese automaker’s hybrid minivan designed and developed primarily for American customers, is expected to enter the 2024 model year in the coming months. That will mark the Chrysler Pacifica rival’s fourth model year. Here’s everything we expect from the 2024 Toyota Sienna Hybrid. Kindly note that the information and visuals featured in this article represent the current model year, and we will keep sharing updates on this page as they emerge.

Design

The current Sienna celebrated its third anniversary on May 18, 2023, and if you ask us, it doesn’t seem old or in need of a redesign. With the 2024 model year update, the Shinkansen-inspired hybrid minivan is unlikely to undergo wholesale design changes.

Features & Grades

We expect the 2024 Toyota Sienna Hybrid to launch with the same premium features such as kick-open and closed sliding side doors and tailgate, Super-Long Slide captain’s chairs with ottomans and a heating function, a 4-zone climate control system, a 12-speaker JBL sound system, and 10-inch color HUD. The new Toyota Audio Multimedia System, made in 8- and 14-inch touchscreen versions, continues to be on our wishlist for the Sienna, but we have no confirmation about its arrival with the MY2024 update.

Going by the nature of past updates, Toyota should carry forward the Sienna Hybrid’s LE, XLE, XSE, Woodland Edition, Limited, and Platinum (pictured in the story) grades with the 2024 model year update. The 25th Anniversary Edition grade (2,525 copies were made during the 2023 model year update) understandably will not be available in the incoming model year.

Safety

Toyota has been offering the Sienna Hybrid with the 2.0 version of Toyota Safety Sense (TSS) ever since its launch as a 2021 model. We expect the company to upgrade the hybrid minivan’s safety suite with the 2024 model year update. There are three newer versions of TSS: 2.5, 2.5+, and 3.0.

Should Toyota offer the 2.5 or 2.5+ version of TSS in the 2024 Sienna Hybrid, the camera and millimeter-wave radar will have been optimized for improved response range and enhanced low-light pedestrian and daytime bicycle recognition. The Pre-Collision System with Pedestrian Detection will have intersection support. It will be able to detect an oncoming vehicle when turning left at an intersection or a pedestrian when turning left or right at an intersection, give the driver audio/visual alerts, and automatically brake in certain conditions.

Emergency Steering Assist, another enhancement in the 2.5 and 2.5+ versions of TSS, stabilizes the steering maneuver during emergency situations while avoiding a pedestrian (2.5 and 2.5+), bicyclist (2.5+), or another vehicle (2.5+). It provides additional steering input to help the vehicle stay within its lane. A Curve Speed Management function (2.5+) of the Dynamic Radar Cruise Control determines if the vehicle needs to slow down when approaching a curve on the road and decelerates it if required.

TSS 3.0 packs an upgraded forward-facing camera with high-res and wider angles and an improved radar sensor for a longer and wider field of view. These hardware upgrades bring new and additional feature capabilities. Moreover, TSS 3.0 is capable of over-the-air updates.

The 3.0 version of TSS brings enhanced intersection support with improved detection range capability, including, in certain circumstances, oncoming vehicles more than one lane while turning and vehicles approaching from a lateral direction. In addition to pedestrian and bicyclist detection, the TSS 3.0 offers motorcyclist detection in certain situations. Lane Departure Alert with Steering Assist provides enhanced lane recognition.

Dynamic Radar Cruise Control in TSS 3.0 has several enhancements, including an additional, fourth cruise distance setting. The new version of TSS also brings improved vehicle detection that leads to smoother, more natural speed adjustments. The new system is designed to detect preceding vehicles in adjacent lanes and can preemptively tweak the speed for the upcoming lane when the driver signals to change lanes.

Proactive Driving Assist, a new feature of TSS 3.0, can provide gentle braking when driving into curves or gentle braking and/or steering to help support driving tasks, such as distance control between the driver’s vehicle and a preceding pedestrian, bicyclist, or vehicle.

Specifications

The 2024 Toyota Sienna shouldn’t have specification changes. The TNGA-K-based minivan should employ the familiar 245-hp Toyota Hybrid System II powertrain that combines a 2.5-liter gas engine with up to two electric motors (front in FWD/front & rear in AWD). A 1.9 kWh Ni-MH battery pack should allow driving solely on electric power at low speeds for short distances. The 2024 Sienna Hybrid may have the same EPA-est. combined fuel economy ratings as the outgoing model: 36 MPG (FWD)/35 MPG (AWD).

Price

The 2024 Toyota Sienna Hybrid’s prices in the U.S. should start at around USD 37,000 and go up to approximately USD 52,500.

Sales

Toyota sold 69,720 units of the Sienna Hybrid in the U.S. in 2022. Compared to 2021 (107,130 units), the hybrid minivan’s annual sales were 37,410 units or 34.9% lower, in a year that was marred by supply chain problems that affected vehicle production.

In the first half of 2023, Toyota delivered 27,937 units of the Sienna Hybrid in the U.S. Compared to the first half of 2022, sales were 18.8% lower. Toyota hasn’t disclosed the particular reason behind the reduction in sales, whether it’s a supply shortage, or a drop in demand, but it’ll have higher expectations from the MY2024 Sienna to reverse the trend.

Though Sienna sales have declined, the units that are sold don’t spend all that long at dealer lots. According to a study iSeeCars conducted based on July 2023 sales, the hybrid MPV ranks 10th on the fastest-selling new car chart for the United States. On an average, it took 22.9 days for a new Sienna to sell. The hybrid MPV fetched USD 51,170 on average, which is pretty close to the price tag of its top-end, Platinum trim – USD 52,345 (excl. USD 1,395 DPH fee).

Fast-moving car in Minnesota & California

iSeeCars‘ study showed that the Sienna was the most popular new vehicle in Minnesota in July 2023. Each unit of the hybrid MPV remained at dealer lots in the Land of 10,000 Lakes for just 18.1 days on average. Interestingly, it was more popular in California, where it took just 11.5 days on an average for it to sell.

TopElectricSUV says

The 2024 Toyota Sienna Hybrid may not pack significant changes. With more than 2.2 million units sold in America since 1997, Toyota should be feeling confident about the Sienna’s continued longevity. As one of the most popular choices of American family van buyers, Toyota’s U.S.-built minivan continues to appeal by checking all the main boxes – affordability, practicality, safety, and efficiency.
