On the TV this morning was an advertisement for the new 2008 Honda Pilot that now comes with what they call is ‘Variable Cylinder Management’ which they state on the Honda website is:
Honda’s innovative Variable Cylinder Management™ (VCM®) helps to increase mileage* and lower emissions by automatically deactivating and reactivating multiple cylinders, depending on the driver’s needs.
Innovative ? Didn’t GM try this back in the 80′s employing this on their Caddies? Back than it was a V-8 that dropped down to either 6 or 4 cylinders depending on the load? Is this really innovative or just a gimmick?
Honda also states:
Powered by the intelligence of i-VTEC® technology, VCM works on the principal that a vehicle only requires a fraction of its power output at cruising speeds. The system electronically deactivates cylinders to reduce fuel consumption. The new VCM engine is able to run on 3, 4 or 6 cylinders based on the power requirement. So you get the best of both worlds: V-6 power when accelerating or climbing, as well as the efficiency of a smaller engine when cruising.
