It's VTEC-Economy.Just... no. The VX had it first, it was followed in the next generation by the HX.
Actually I think we both may be right. The Haynes Manual for my car says that VTEC-E is Honda's designation for "enhanced performance."
However, I did some research and found
this site. I quote, "The two engines are essentially the same except for the VTEC-E in the Civic HX. But the Civic HX's VTEC-E mechanism results in 115hp, versus 106hp from the Civic DX. So the Civic HX has more power in addition to better fuel economy. But make no mistake, VTEC-E is designed with economy as the primary goal, not power output."
Draw.
