How many cylinders are in a Toyota Avalon?
Typically six cylinders in gasoline Avalons; four cylinders in Avalon Hybrid. The exact count depends on the model and generation.
The Avalon has been produced in several generations since the mid-1990s. Early generations used a V6 with six cylinders, while the later hybrid version uses a four-cylinder engine paired with electric motors. The sections below break down the cylinder configurations by variant.
Gasoline-only Avalons: six-cylinder V6 engines
Gasoline-only Avalons have used six-cylinder V6 engines across generations, with the displacement shifting from 3.0 liters in the earliest generations to 3.5 liters in later ones.
- First- and second-generation Avalons used a 3.0L V6 (six cylinders).
- Subsequent generations switched to a 3.5L V6 (six cylinders).
In short, all gasoline-only Avalons from these generations run a six-cylinder V6 engine.
Avalon Hybrid: four-cylinder engine with electric motors
The Avalon Hybrid pairs a four-cylinder gasoline engine with an electric motor system as part of Toyota’s Hybrid Synergy Drive.
- Avalon Hybrid uses a 2.5L four-cylinder engine (Atkinson-cycle) along with electric motors, for a total of four gasoline cylinders.
In summary, the hybrid variant uses a four-cylinder engine, while the gasoline-only variants use six-cylinder V6 engines.
Summary
The Toyota Avalon comes in two primary engine configurations: a six-cylinder V6 for gasoline-only models and a four-cylinder engine paired with electric motors for the Avalon Hybrid. If you’re unsure which engine your Avalon has, check the vehicle’s badge, the engine code on the engine itself, or the owner's manual to confirm the cylinder count and configuration.
