Yes. The 2015 Honda Accord equipped with the 3.5-liter V6 uses Honda's i-VTEC system to manage variable valve timing and lift.
Understanding VTEC in Honda engines
VTEC, or Variable Valve Timing and Lift Electronic Control, is Honda's system that adjusts when and how much the engine's valves open. In modern engines, VTEC is typically branded as i-VTEC, which adds electronic control to vary both cam timing and lift profiles across a range of engine speeds. This allows the engine to deliver stronger performance at higher RPMs while maintaining smooth operation and better fuel economy at lower RPMs.
What makes the 3.5L V6 different
The 3.5-liter V6 used in the 2015 Accord is a dual overhead cam (DOHC) design that employs i-VTEC on both the intake and exhaust cams. This setup enables variable valve timing and lift to optimize power, response and efficiency across rpm ranges, contributing to the engine's strong mid-range torque and smooth power delivery.
Performance context for the 2015 Accord V6
In typical configurations for the 2015 model year, the V6 produces around 278 horsepower and 252 lb-ft of torque, with the i-VTEC system helping the engine perform well in everyday driving and in acceleration. The system works automatically, so drivers experience the benefits without needing to adjust anything manually.
Bottom line
The 2015 Honda Accord V6 does have VTEC technology, implemented as i-VTEC, on its 3.5L V6 engine. This is Honda's standard approach to variable valve timing and lift in modern engines, designed to balance performance with efficiency.
Summary
Yes — the 2015 Accord V6 uses i-VTEC on a 3.5-liter V6, delivering variable valve timing and lift to optimize power and efficiency across driving conditions. This aligns with Honda's long-running VTEC approach across its V6 lineup.
