Is the Toyota Sienna a 4 or 6 cylinder?
The latest Toyota Sienna uses a four-cylinder hybrid powertrain in all current models, while older generations offered a six-cylinder option. This article outlines the current setup and how it compares to past versions.
Current generation powertrain: four-cylinder hybrid (2021–present)
The modern Sienna is powered by a 2.5-liter inline-four gasoline engine paired with electric motors, delivering a combined output around 245 horsepower. An all-wheel-drive option is available that uses a rear electric motor to aid traction.
Powertrain details
In this generation, every Sienna uses a 2.5-liter inline-four engine with one or more electric motors and an e-CVT (continuously variable transmission). The setup emphasizes efficiency and smooth, quiet operation, with AWD available through an additional rear motor.
Key specifications of the current Sienna’s four-cylinder hybrid are listed below.
- Engine: 2.5-liter inline-four hybrid
- Motors: one or more electric motors (including a rear motor for AWD)
- Transmission: e-CVT
- Combined power: about 245 horsepower
- Drivetrain: front-wheel drive standard; all-wheel drive available
- Fuel economy: typical efficiency in the mid-30s mpg range, varies by configuration
In short, the current Sienna is a four-cylinder hybrid with an optional AWD system and no gasoline-only V6 option.
Historical powertrain options (pre-2021): the six-cylinder option
Before the 2021 redesign, the Sienna offered a gasoline-powered 3.5-liter V6 as the primary engine in most trims. This setup was paired with an automatic transmission and provided stronger onboard performance, with optional all-wheel drive depending on the model year.
Legacy engine overview
- Engine: 3.5-liter V6 gasoline
- Transmission: automatic (typical configurations used a conventional automatic transmission)
- Drive: front-wheel drive standard; all-wheel drive available on some trims
- Power: roughly in the mid-to-upper 200s horsepower (varies by year and trim)
For shoppers considering older Sienna models, a V6 offering means more traditional, higher-powered acceleration but lower fuel economy compared with the current hybrid setup.
Bottom line and quick guidance
For the latest models (2021–present), the Sienna is a four-cylinder hybrid. For earlier generations (pre-2021), it could be equipped with a six-cylinder gasoline engine. When shopping, check the specific model year and trim to confirm the engine configuration and drivetrain.
Summary
The Toyota Sienna’s cylinder count depends on model year: four-cylinder hybrid in the current generation, versus a six-cylinder gasoline engine in most pre-2021 versions. The shift to a hybrid four-cylinder aimed to improve fuel efficiency and reduce emissions, while older V6 variants offered stronger raw power. Always verify the exact engine configuration for a given vehicle year and trim when evaluating a used Sienna.
