Unlike everyone who has posted here so far, the guy at the dealership was almost CORRECT! Everyone, so far, has described Honda's old version of VTEC (no H). The newer engines come with iVTEC, which is a little different. But the V6 Honda engines have an even different version of iVTEC. At low rpms, the valves on 3 of the cylinders close shut. This helps greatly with fuel economy, and "coasting". At a certain rpm, the cam profile changes to allow the valves in the 3 cylinders to open with the rest of them. 4th paragraph down: http://www.123usedcars.com/road-test...y/index.htmlIf you do a google search of "ivtec v6" you'll find hundreds of links about it.And VTEC or iVTEC does not act like a turbo. People exaggerate how VTEC feels when it kicks in. Some of the B-series engines will let you feel it a little more than others, but it's nothing like a turbo. In fact, most of the time it's just in their head, from hearing the exhaust get louder at VTEC cross over.
