Two gasoline engines were offered: a 2.4-liter inline-4 and a 3.0-liter V6; there was also a hybrid version pairing the V6 with an electric motor.
Engine options by model and trim
Here’s how the engines were typically matched to trims in the U.S. market for the 2007 Accord. The four-cylinder option is the baseline, while the V6 provides more performance in higher trims. A hybrid version used the same V6 powertrain with an electric motor.
- 2.4-liter inline-4 i-VTEC — Approximately 166 horsepower and 160 lb-ft of torque. This engine was common in the base and mid-range trims and is known for smooth power delivery and reasonable fuel economy.
- 3.0-liter V6 i-VTEC — Approximately 244 horsepower and 211 lb-ft of torque. Available in higher trims, including EX and EX-L, this engine offered noticeably stronger performance and quicker acceleration.
Note: There was also a hybrid variant of the 2007 Accord that combined the 3.0-liter V6 with Honda’s IMA electric motor system, producing a higher total output and a different drivetrain setup than the gasoline-only models.
Engine basics and performance context
The 2.4L inline-4 emphasized efficiency and everyday usability, while the 3.0L V6 delivered more robust performance for drivers seeking stronger acceleration and highway capability. The hybrid version targeted buyers who wanted better fuel economy without sacrificing the V6’s power.
Technical notes
Both gasoline engines are DOHC designs with Honda’s i-VTEC variable valve timing technology. The four-cylinder models were paired with either a 5-speed manual or a 5-speed automatic, while the V6 options typically used the automatic transmission. The hybrid version used Honda’s IMA system to combine the gas engine with an electric motor for improved efficiency.
Summary
The 2007 Honda Accord offered two main gasoline engines: a 2.4-liter inline-4 and a 3.0-liter V6, both with i-VTEC, plus a hybrid variant that combined the V6 with an electric motor. Your choice depended on trim and priorities—fuel efficiency vs. performance—with the hybrid providing the best overall efficiency among the options.
