Two engines were offered: the 2.4-liter four-cylinder with 166 horsepower and the 3.0-liter V6 with 244 horsepower.
Engine options and horsepower
The 2006 Accord lineup included a pair of powertrains, each with its own horsepower rating. The figures below reflect U.S.-spec models and official ratings from Honda at the time.
The following list summarizes the horsepower for each engine option in the 2006 Accord:
- 2.4-liter inline-four (K-series) — 166 horsepower (around 5,800 rpm)
- 3.0-liter V6 (J-series) — 244 horsepower (around 6,200 rpm)
Conclusion: The engine choice primarily determined performance—the four-cylinder prioritizes efficiency, while the V6 delivers stronger acceleration thanks to its higher horsepower.
Performance context
In practice, horsepower interacts with transmission, gearing, weight, and drivetrain to shape daily performance. The V6 sedan and coupe provided quicker acceleration, while the four-cylinder model offered better fuel economy and lower emissions in many trims.
Summary
The 2006 Honda Accord offered two horsepower ratings based on engine choice: 166 hp from the 2.4-liter four-cylinder and 244 hp from the 3.0-liter V6. This difference defined the car’s performance range across trims and configurations.
