Is Toyota Sienna 4-cylinder or 6?
The latest Toyota Sienna uses a 2.5-liter four-cylinder hybrid powertrain, not a traditional V6. In current generations (2021 onward) Toyota dropped the V6 in favor of a hybrid-only setup; older Sienna models did offer a V6 option.
Current generation engine and performance
Powertrain overview
The contemporary Sienna relies on a 2.5-liter inline-4 gasoline engine paired with electric motors in a hybrid system. The combined output is around 245 horsepower, and power is delivered through an electronic continuously variable transmission (e-CVT). All-wheel drive is available as an option, with front-wheel drive as the standard setup.
Here are the key specs of the current generation's hybrid powertrain:
- Engine: 2.5-liter inline-4 Atkinson-cycle gasoline engine
- Hybrid system: two electric motors, total system horsepower around 245
- Transmission: e-CVT (electronic continuously variable transmission)
- Drivetrain: FWD standard; AWD available
- Fuel economy: typically in the mid-30s mpg range depending on drivetrain and configuration
In sum, the modern Sienna is engineered around a four-cylinder hybrid setup designed for efficiency and smooth operation rather than a traditional V6.
Older Toyota Sienna engine options (pre-2021)
Before the 2021 redesign, the Sienna was offered with a traditional V6 engine and a conventional automatic transmission, and there was no hybrid option in those generations.
Here’s a quick look at the main characteristics of the older engine option:
- Engine: 3.5-liter V6
- Power: roughly 266 horsepower
- Transmission: conventional automatic transmission
- Drivetrain: usually front-wheel drive with optional all-wheel drive
- Notes: No hybrid powertrain in those generations; the V6 was the standard alternative to the hybrid setup introduced later
So, while earlier Sienna models offered a robust V6, the current lineup relies on a four-cylinder hybrid configuration.
Summary
The Toyota Sienna currently uses a four-cylinder hybrid powertrain (2.5-liter inline-4) with electric motors for a combined output around 245 horsepower, and it does not offer a traditional V6 in its modern form. If you’re looking at a used model from before 2021, you may encounter the 3.5-liter V6 option, but new models are four-cylinder hybrids only.

Which Toyota models have a V6 engine?
The Toyota Sequoia and Tundra are the primary Toyota models that currently offer a V6 engine in the United States, both using a twin-turbocharged 3.4L V6. The Sequoia uses a hybrid version called the i-FORCE MAX, while the Tundra has both a standard i-FORCE V6 and the hybrid i-FORCE MAX option available. Toyota is phasing out V6 engines in many other models, such as the Camry, Tacoma, and 4Runner, in favor of 4-cylinder engines.
