"Powered by the intelligence of i-VTEC=AE technology, VCM=99 quickly and seamlessly activates or deactivates the three rear cylinders, depending on the driver's needs. So you get the best of both worlds: V-6 power when accelerating or climbing, as well as the efficiency of a smaller engine while cruising."
am i understanding correctly? an engine which configures the number of cylinders in use on the fly? anyone understand if this really saves fuel/money (i am imagining friction/wear and tear/incredibly complex valvetrain etc). if it really does save money then i would be truely impressed.
