VTEC uses two (or occasionally three) camshaft profiles and hydraulically selects between profiles. It was invented by Honda engineer Ikuo Kajitani. It is distinctly different from standard VVT (variable valve timing) systems which change only the valve

VTEC (Variable Valve Timing and Lift Electronic Control) é um sistema de comando de válvulas variável, desenvolvido pela Honda em 1983, para aumentar o torque dos motores em baixas e altas rotações. Foi inventado pelo engenheiro da Honda, Ikuo Kajitani. O sistema VTEC utiliza dois perfis de árvore de cames, selecionando hidraulicamente. É diferente do sistema VVT da Toyota, que avança apenas o sincronismo da válvula e não altera o perfil da árvore de cames. Depois veio o dual vvt, que já seria comando duplo.
