Honda's name for their variable valve timing system that happens to include electronic lift control. (See also : MIVEC, VVTL-i, VariCam Plus, VANOS, and VVL. )
For combustion engines, it allows the increase of air and fuel consumption when VTEC is engaged.
Due to its "lift control", VTEC doesn't engage until higher RPMs to save fuel. Once engaged however, fuel economy drops significantly as performance increases by 20 - 30 horsepower with an increase of torque efficiency.
To market their "economy" cars, Honda used VTEC to have higher horse-power claims. Most of their horsepower claims are at high RPM marks (7,500 or higher), whereas other motor companies make their claims at lower RPM marks (5,500 or below).
This confused most buyers as they thought that engaging their VTEC would allow for them to enjoy peak fuel economy AND peak performance at the same time (hence grew the term to mock VTEC-users; "vtak just kicked in yo!")
To add to the illusion of performance (but keep the status of "economy car"), most VTEC-motors were dropped into chassis with a front-wheel drive drive train (with the S2000 and NSX exempt).
Due to their front-wheeled drive pull, some VTEC users became euphoric in what seemed to be a "fast" car(though it was mostly because of the "pull" force from the car being a FWD vehicle).
Ultimately, the concept of variable valve timing and lift control is now used by other car companies.
Person A : "I got a VTEC motor." *Grin*
Person B : "I bet that guy is a ricer."
"My RSX goes 0-60 in 7.8 seconds. It's got a VTEC."
Person B : "Dude, why do you have that gay looking spoiler on your Civic?" :/
Person A : "Are you stupid or something! Dude, it's got a VTEC. There has to be something to hold down its rear-end or I could spin the fuck out!"
the thing that always kicks in, yo!
vtec just kicked in, yo!
VTEC=Variable timing and lift electronic control.
By changing the variable timing and lift these engines can perform better than it's normal non-VTEC cousins. More horsepower, torque, revolutions per minute and so on.

VTEC - Variable Valve timing and Lift Electronic Control and is an electronic and mechanical system in some Honda engines that allows the engine to have multiple camshafts. VTEC engines have an extra intake cam with its own rocker, which follows this cam. The profile on this cam keeps the intake valve open longer than the other cam profile. At low engine speeds, this rocker is not connected to any valves. At high engine speeds, a piston locks the extra rocker to the two rockers that control the two intake valves.
Honda has VTEC to increase efficiency not increase performance.
A "performance enhancing technology" employed by Honda in its "high-performance" "engines."
My Civic makes 130hp and 12 ft/lb of torque, yo.
VTEC keeps the hamsters from getting too tired.
Wait, you mean a bottle of Mountain Dew displaces more than my engine?
variable valve timing and lift control. several other car companies use the same thing but with different acronims:
even though they are essentialy the same, each one dose have it's flaws for example:
vtec has very little torque.
VVL parts are rare and hard to come by.
VTC only works on the intake cam.
Honda guy: yeah i got more power cause i gots vtec.
nissan guy: *coughs* no torque *coughs*
ford guy: you know he's right
Honda and Nissan guy: shut up, you car doesn't even run.
Variable valve Timing and lift Electronic Control.
engine's powerbands are limited to their cam lobe profile, by using multiple cam profiles, honda's VTEC system enables a much larger powerband. Not to be confused with VTECH electronics.
"Using mad 3rd gear vtec, I was able to pass the del sol.
A term for Honda's valve timing system on most of their cars. Unfortunatly, it does not kick in until higher RPMs, thereby essetially doing nothing for acceleration. It's a poor excuse for losers in drag races.
I forgot to turn on my VTEC. *switches on foglights*
