The 2005 Honda Accord EX is typically equipped with a 2.4-liter inline-four engine in the U.S. market, though an EX-V6 variant offered a 3.0-liter V6. This article explains the two engine options and what they mean for the EX model.
Engine options in the 2005 Accord
The 2005 Accord lineup offered two main engine configurations. A four-cylinder engine powered most EX models, while the EX-V6 carried a larger V6. The following options summarize the engines available for that year:
- 2.4-liter inline-four (I-4) engine for the EX (and most LX/EX trims in the US).
- 3.0-liter V6 engine for the EX-V6 variant.
In practice, this means that a 2005 Accord EX is almost always the four-cylinder version, whereas the EX-V6 sits on the V6 option.
Performance details by engine
Four-cylinder option
The 2.4-liter inline-four delivers roughly 166 horsepower and around 160 lb-ft of torque, with performance and fuel economy appropriate to mid-2000s mid-size sedans. Output can vary slightly by transmission and market.
V6 option
The 3.0-liter V6 in the EX-V6 produces about 244 horsepower and roughly 211 lb-ft of torque, providing stronger acceleration and towing capability compared with the four-cylinder variant.
Note that availability of these engines could vary by market and the specific build; base LX/EX cars in some regions used the 2.4L engine, while EX-V6 was a separate trim line.
Summary
In short, a 2005 Honda Accord EX is typically powered by a 2.4-liter inline-four engine. If you encounter an EX-V6, that model uses a 3.0-liter V6 instead. Understanding these options helps identify the exact engine under the hood when shopping or restoring a 2005 Accord.
