What engine does Toyota Avalon use?
The Avalon offers two powertrain options: a 3.5-liter V6 for standard gasoline models and a 2.5-liter inline-4 hybrid for the hybrid version. This article breaks down what drives the Avalon and how the engines differ across trim levels and generations.
Engine options by variant
Before listing the engines, note that Toyota has differentiated Avalon trims with distinct powertrains. Here are the two primary configurations you’ll encounter:
- Gasoline-only Avalon: 3.5-liter V6 engine (2GR-FKS) paired with an 8-speed automatic transmission. This setup delivers about 301 horsepower and strong on-road performance.
- Avalon Hybrid: 2.5-liter inline-4 engine (A25A-FXS) combined with electric motors in a Hybrid Synergy Drive system. The combined output is typically around 208–215 horsepower, with the drivetrain leaning toward efficiency and smooth acceleration.
In general, the non-hybrid Avalon uses a traditional V6 with a conventional automatic gearbox, while the hybrid relies on a gasoline/electric powertrain for better fuel economy. The hybrid is designed to maximize efficiency without sacrificing the Avalon’s characteristic comfort and pace.
How the two powertrains differ in practice
Gasoline V6 details
The standard Avalon’s 3.5-liter V6 (2GR-FKS) produces about 301 hp and around 267 lb-ft of torque. It is paired with an 8-speed automatic transmission and delivers confident acceleration for daily driving and highway merging, along with a refined, quiet cabin experience.
Hybrid powertrain details
The Avalon Hybrid uses a 2.5-liter inline-4 Atkinson-cycle engine (A25A-FXS) along with electric motors to form Toyota’s Hybrid Synergy Drive. This setup emphasizes fuel efficiency and smooth, steady performance, with a combined output typically cited around 208–215 hp. A dedicated hybrid transmission (often an electronically controlled CVT-like setup) manages the power delivery to the front wheels for most configurations.
Model-year notes and availability
Across its run in North America, the Avalon has consistently offered these two powertrain options, with refinements to efficiency and tuning over different model years. The V6 remains the choice for those prioritizing outright power and a traditional driving feel, while the Hybrid appeals to buyers seeking better fuel economy without sacrificing comfort or space.
Summary
In short, the Toyota Avalon is powered by two core engine configurations: a 3.5-liter V6 for gasoline-only models and a 2.5-liter inline-4 hybrid for the hybrid version. Each setup is paired with its respective transmission and tuned for a balance of performance and efficiency, making the Avalon versatile for different driving preferences.
Is the Avalon just a Camry?
The Avalon is just a little bigger than the Camry. It fits into the full-size sedan market where the Camry is a mid-size car.
What engine is in a Toyota Avalon?
3.5-liter V-6
A 3.5-liter V-6 that delivers 301 horsepower and 267 lb-ft of torque is standard. An eight-speed automatic transmission sends power to the front wheels.
What is the common problem of Toyota Avalon?
Common problems for the Toyota Avalon include ignition coil failures, especially after 100,000 miles, and leaking valve cover gaskets. Other issues include problems with the automatic transmission, such as rough shifting, and issues with the Evaporative Emission Control System (EVAP) (like a faulty canister or purge valve) which can cause a check engine light. Some model years have also reported specific issues like unintended acceleration and peeling paint.

Engine
- Ignition Coils: May fail after 100,000 miles, leading to misfires and a check engine light.
- Oil Leaks: Valve cover gaskets are a common source of oil leaks.
- EVAP System: Issues with the EVAP canister or purge control valve can trigger the check engine light.
- Oxygen Sensor: A failed oxygen sensor can cause the check engine light to turn on.
- Sludge Buildup: Can occur with infrequent oil changes and cause engine problems.
Drivetrain and transmission
- Automatic Transmission: Some owners report the transmission not shifting correctly at higher mileages.
- Unintended Acceleration: A serious problem reported in some models, particularly the 2014 model year, where the gas pedal may become stuck.
Other common issues
- Rear Window Sunshade: This feature has been reported to fail and make a grinding noise.
- Peeling Paint: A problem reported on certain model years, often on the roof and around the sunroof.
- Infotainment System: Some owners have complained about distorted speakers and issues with the infotainment system.
