VTEC, or Variable Valve Timing and Lift Electronic Control, is a technology developed by Honda to optimize engine performance. It allows the engine to adjust the timing and lift of the intake valves, improving efficiency and power at different RPMs. This means that the engine can perform better at both low and high speeds. By using VTEC, engines can achieve a balance between fuel efficiency and power output. When the engine reaches a certain RPM, the system activates, changing the valve operation to enhance performance. This technology is commonly found in many Honda vehicles, contributing to their reputation for reliability and sporty driving experiences.
