| Cars gone Vanos??? (BMW and every other new car??) Is it me, my lack of knowledge, or is it every new car has the Variable Valve Timing(aka Vanos)??? I recently read a few car magazines and almoust every new car is comming out with it..... This sux because i thought it was original to BMW(since 93??)... but as i can see not anymore...

| I donno if every new car has VVT, but I'm pretty sure that this is true... BMW didn't invent VVT/Vanos in '93, ferarri was the first manufacturer to entroduce it in early 60's(i think) in their race cars... |

| Lack of knowledge. Vanos is just BMW's name for a variable cam timing system. BMW's been using it since 92 with the M3. These type of cam systems aren't a result of BMW. Im sure Honda or somebody started cam timing systems in production cars before BMW did. The important thing isnt who made it first. Its who makes it better. Double vanos.... BABY! |

| Well don't worry BMW will be going to Valvtronic in all engines soon ahead of the competition. Valvetronic, a BMW patented design that regulates the adjustment of the intake valve lift from fully closed to fully opened. This, says BMW, is a quantum leap rivaling the industry switch from carburetors to fuel injection or the jump from points and condenser to electronic ignition. What makes this so earthshaking is that when you step on the gas pedal, you are no longer controlling the throttle plate. Instead, engine speed is controlled by the Valvetronic system directly by varying the amount of intake valve lift based on how hard you step on the gas. There is still a throttle plate, but it is only used as a failsafe or for certain diagnostic functions. Under normal operation, the throttle plate is held wide open, which means that there is no longer any vacuum in the intake manifold. To compensate, they have added an engine-driven pump to provide vacuum for the brake booster. Under normal driving conditions, this system allows the intake valves to open as little as half a millimeter, causing the fuel/air mixture to enter the combustion chamber through an almost paper-thin valve opening. This lets the fuel vaporize more fully, significantly increasing combustion efficiency. Another advantage is that controlling the air flow right at the combustion chamber instead of way up at the throttle plate, makes throttle response virtually instantaneous because there is no lag between stepping on the gas and engine response. |
