Big difference between VTEC and Vanos

["Adam Ee-Sun Koo" <isd2k@xxxxxxxxxxx>]

There is a big difference between VTEC and Vanos.
VTEC stands for Variable Valve Timing and Lift Electonic Control. Whilst 
BMW's Vanos is only variable valve timing control only, not lift.

Therefore, we are comparing apples to oranges here. If one has to compare 
Vanos to same type of variable timing, it will be Toyota's VVT-i (the 140hp 
in Celica GT).

Honda's VTEC, Toyota's VVTL-I and Nissan's VVL are more complex technical 
advancement in valve timing and lift control

Below is a link to a clearer picture of valve timing.
