That's just outright funny how people proclaim 15-18 year old VTEC technology as superior to VVT-i technology, which was more or less geared for the same purpose: more power.
VVT-i > VTEC for more reasons that I could possibly type out, which would only bore the shit out of you all. ;)
Main reasons are VTEC acts as an on/off switch, whereas VVT-i is infinitely a variable throughout the entire powerband, and it's CONTINUOUS from the moment you start the engine.
The "i" for intelligent marks its clever control program which varies the timing of the valves not only by engine speed (RPMs) but acceleration (so it senses your lead foot) and going uphill or downhill.
VVT-i has better overall useable power, fuel economy, more intelligent, wider tq band, more smoothness, better acceleration, and more reliable because everytime VTEC kicks in, your valvetrain weakens, your gas consumption goes up, and VTEC solenoids use up a lot more oil, where VVT-i has more efficient uses for the same engine oil.
I could go on and on, but VTEC pales in comparison to VVT-i.
