The 2007 Toyota Avalon offered two powertrain options: a standard 3.5-liter V6 and a hybrid variant that combines the same V6 with electric motor assistance. In short, the gasoline Avalon uses the 3.5L V6 (2GR-FE), while the Avalon Hybrid uses the same displacement with a hybrid system (2GR-FXE).
Engine options by configuration
Two engine configurations were available for the 2007 Avalon, depending on whether you chose the conventional gasoline model or the hybrid. The following outlines the engines and the typical drivetrain pairings for each setup.
- Gasoline-only Avalon: 3.5-liter V6 engine (2GR-FE) paired with a five-speed automatic transmission.
- Avalon Hybrid: 3.5-liter V6 engine (2GR-FXE) integrated with Toyota's Hybrid Synergy Drive and an electronically controlled continuously variable transmission (ECVT) for smooth power delivery.
In short, the 2007 Avalon offered two powertrain configurations: a conventional 3.5L V6 and a hybrid variant that uses the same engine with hybrid hardware for efficiency.
Engine specifics
Gasoline engine: 2GR-FE
The standard 2007 Avalon uses a 3.5-liter V6 with a Dual Overhead Cam (DOHC) design and variable valve timing (2GR-FE). This engine is paired with a traditional five-speed automatic transmission in most trim levels, delivering smooth and refined acceleration suitable for a full-size sedan.
Avalon Hybrid powertrain: 2GR-FXE
The Avalon Hybrid employs the 3.5-liter V6 configured for the Atkinson cycle (2GR-FXE) alongside electric motors as part of Toyota’s Hybrid Synergy Drive. This setup typically uses an electronically controlled CVT to blend engine and electric power for improved efficiency while maintaining a smooth driving experience.
Summary
For the 2007 Toyota Avalon, the engine choices were straightforward: a gasoline-only model with a 3.5-liter V6 (2GR-FE) and a hybrid model using the same displacement (2GR-FXE) with hybrid hardware. The gasoline version emphasizes traditional power and refinement, while the hybrid version prioritizes fuel efficiency without sacrificing comfort.
