[quote=7red7;357484]Being that I regularly drive between the 70-80mph mark, I'm interested to know how the VTEC affects the car. Please forgive me, but the Fit is my first Honda so I admit it I'm a complete noob with this. There are explanations online as to what VTEC does to the engine, but I get lost in the physics of it all. Can anyone break it down to me what VTEC actually does, why it kicks in, and if driving at speeds that regularly see it in use causes harm to the car??? Am I just flipping out for no reason and should shut up and enjoy my new car???
Vtec is Honda's name for changing the camshaft that controls the valves that let air-fuel into the engine and lets the combusted mixture out.
Efficient control of the valves at low rpm is different than the control at high rpm and if you want efficient valves at low rpm and at high rpm you need to change cams, So when the vtec system switches cams you are in need of more power to do what you're doing.
And yes, it generally means you are using more gasoline, less mpg. Its nothing for you to be concerned about. Let Honda do the worrying.
