Two engines were offered: a 2.7-liter inline-four (2TR-FE) and a 4.0-liter V6 (1GR-FE). The 2.7L powered base models, while the 4.0L was optional on higher trims and 4x4 configurations.
As part of the second-generation Tacoma introduced in 2005, the larger V6 brought significantly more power for towing and payloads, while the four-cylinder kept costs and fuel use down for lighter tasks. Engine choice varied by trim and drivetrain.
Engine options at a glance
Here is a concise look at each engine and its typical performance depending on configuration.
- 2.7-liter inline-four (2TR-FE) — Used on base models; typically around 159–165 horsepower with about 180 lb-ft of torque. It emphasizes fuel economy and daily usability for light-duty work.
- 4.0-liter V6 (1GR-FE) — Optional on higher trims and 4x4 models; roughly 236 horsepower with about 266–278 lb-ft of torque. It delivers stronger towing and payload capability for more demanding use.
In short, the 2005 Tacoma offered two engine configurations to match different needs: a economical four-cylinder and a more capable six-cylinder, with availability tied to trim and drivetrain.
Summary
The 2005 Toyota Tacoma could be equipped with either a 2.7L inline-four (2TR-FE) or a 4.0L V6 (1GR-FE). The four-cylinder served as the base option for efficiency, while the V6 upgrade provided superior power for towing and heavier workloads. This mirrored the model’s shift into the second generation, aimed at expanding capability while maintaining a compact-truck footprint.
