The 2015 Honda Accord offered two engine choices: a 2.4-liter inline-4 and a 3.5-liter V6.
In that model year, Honda positioned the four-cylinder option as the efficient standard-bearer, while the V6 delivered stronger performance. Both engines used Honda’s i-VTEC variable-valve timing system to optimize power and efficiency across rev ranges.
Engine options
The following summarizes the two engine options available for the 2015 Accord, including their core power output.
- 2.4-liter inline-4 i-VTEC: approximately 185 horsepower and 181 lb-ft of torque.
- 3.5-liter V6: approximately 278 horsepower and 252 lb-ft of torque.
These figures reflect the two-engine lineup for that year, with the four-cylinder carrying the aim of fuel efficiency and the V6 offering notably stronger acceleration.
Transmission pairings by engine
The typical drivetrain pairings for the two engines in the 2015 Accord were as follows, reflecting Honda’s approach to balancing efficiency and performance.
- 2.4-liter inline-4: commonly paired with a Continuously Variable Transmission (CVT) across most trims.
- 3.5-liter V6: paired with a 6-speed automatic transmission.
In short, the four-cylinder model emphasized efficiency with its CVT, while the V6 leaned on a traditional automatic for a more responsive driving feel.
Summary
For the 2015 Honda Accord, buyers could choose between a 2.4-liter inline-4 or a 3.5-liter V6. The four-cylinder engine produced about 185 hp and was typically matched with a CVT, prioritizing fuel economy. The V6 produced around 278 hp and used a 6-speed automatic, delivering stronger performance. Together, these options defined the Accord’s hybrid of efficiency and power for that model year.
