Yes. The 2015 Civic EX uses Honda's i-VTEC engine, which includes VTEC technology.
Engine details for the 2015 Civic EX
The 2015 Civic EX sits in the ninth-generation lineup (2012–2015) and is powered by a 1.8-liter i-VTEC four-cylinder engine. This non-Si engine prioritizes a balance of everyday efficiency and usable performance, with the i-VTEC system enabling variable valve timing for better fuel economy at low to mid RPM and enhanced power at higher RPMs.
What i-VTEC means in this context
VTEC stands for Variable Valve Timing and Lift Electronic Control. In the Civic EX’s 1.8-liter engine, i-VTEC applies electronic control to vary the cam profile—primarily on the intake valves—to optimize performance across different speeds. This allows the engine to behave like a frugal commuter at low RPMs while delivering more power as engine speed increases.
How the EX compares to other Civic trims
While the EX uses the 1.8-liter i-VTEC engine, the Civic Si in the same generation offers a higher-output 2.4-liter i-VTEC engine. Both families use VTEC technology, but the Si is tuned for performance, whereas the EX emphasizes a balance of efficiency and practicality for everyday driving.
Bottom line
Yes—the 2015 Honda Civic EX features VTEC technology through Honda’s i-VTEC system on its 1.8-liter engine. This provides variable valve timing to improve efficiency and drivability without the higher-performance focus of the Si.
Summary
The 2015 Civic EX demonstrates Honda’s continued use of VTEC in mainstream Civics. With a 1.8-liter i-VTEC engine, it achieves a practical blend of efficiency and everyday power, proving that VTEC isn’t exclusive to the sportier Si trim.
