Is a Toyota Sienna a V6?

The current Toyota Sienna is not a V6. Since its 2021 redesign, the minivan has been sold exclusively with a hybrid powertrain that pairs a 2.5-liter four-cylinder gasoline engine with electric motors.


Current powertrain and driving figures


What has changed with the latest generation


Here are the core details of the Sienna's powertrain in the present generation.



  • Hybrid-only design: there is no traditional V6 option in the current generation.

  • Gas engine: 2.5-liter inline-four Atkinson-cycle gasoline engine works with electric motors to provide power.

  • Combined output: about 245 horsepower when the gasoline engine and electric motors work together.

  • Transmission: electronically controlled continuously variable transmission (eCVT).

  • Drivetrain: front-wheel drive is standard; all-wheel drive is available on hybrid models.

  • Efficiency and practicality: typical real-world fuel economy is in the mid-30s mpg, depending on trim and driving conditions.


In short, buyers seeking a Sienna with a V6 will not find one in the current generation; the focus is on hybrid efficiency and family hauling capability.


Historical engines by generation


Generational overview of Sienna engines


For context, the Sienna's engine lineup evolved across generations. Earlier models used V6 powerplants to balance performance with utility.



  1. First generation (1998–2003): 3.0-liter V6 used in the early Sienna models.

  2. Second generation (2004–2010): 3.3-liter V6 carried the lineup, continuing the traditional V6 approach.

  3. Third generation (2011–2020): 3.5-liter V6 became standard for higher trims, with robust towing capability.

  4. Fourth generation (2021–present): Hybrid-only propulsion with a 2.5-liter four-cylinder gasoline engine paired with electric motors; no V6 option.


These shifts reflect Toyota's broader move toward electrified powertrains in the Sienna while preserving practicality for families that need reliable, spacious transportation.


What this means for buyers


For shoppers prioritizing a V6, the current Sienna does not offer one. If hybrid efficiency, standard seating for families, and available all-wheel drive are appealing, the Sienna remains a strong option. Those seeking traditional V6 performance or high towing capacity might consider looking at older used Sienna models with V6 powertrains or evaluating other Toyota offerings in the minivan and SUV segments.


Summary


The Toyota Sienna's latest generation is not a V6; it relies on a 2.5-liter four-cylinder hybrid system producing around 245 horsepower. While previous generations used various V6 engines, the 2021–present Sienna marks a shift toward hybrid efficiency and modern electrified powertrains, with no V6 option available.
