    I haven't looked at them all but in my opinion it has to be the Ferrari system -> it is very simple (and ingenious).
    This is how it works.

    i heard somewhere that BMW's valves are organised as 1 exhaust valve/3 intake valve. can anyone confirm that? which manufacturer do u think will be the first to come up with a 5 valve, direct injection, twin spark engine with each valve individually controlled by computer?

    Slightly off topic, but American visitors might check the Ford Diesel mentioned in the top ten. Somebody appears to be waking up over there.

    Too bad it lacks torque.

    VVT is nothing new. Some may be different than others, but they're all pretty much the same.

    I perfer BMW's.

    What do you mean it lacks torque? It has an incredible amount of torque for a 2 liter engine and hte torque curve is incredibly flat.

    I heard you have to drop the clutch at really high RPMs because the S2K lacks low end torque, damn it. I obviously heard wrong.
