That's pretty low MPG for your Odyssey. I get about 30 in my 2003 when driving on the highways mostly. I got about 30 when I did 3500 miles from OKC to DC/Philly/Boston and back last fall.

However, I am glad to hear of your Bullitt's MPGs as I have a 2000 Accord 4cyl that barely gets 28 MPG on a mostly highway commute (16 of 17 miles).

 

The trouble with cylinder deactivation is that you are still rotating eight pistons, pins, connecting rods and a full crankshaft and full camshafts & their related gear even though the deactivated cylinders contribute absolutely NOTHING to move your vehicle down the road--in fact, in addition to continuing to place wear on all these parts you create additional drag on the cylinders that ARE activated. As a concept, there has to be a better way--even if you can save a little fuel by doing this. MUCH better would be to trade the vehicle in on a vehicle with a six or a four--in those engines your "deactivated cylinders" add no drag, no weight, and no wear because the engine never had them to begin with! VASTLY superior!

Best of all, turn the engine off completely and harness 20 naked babes up front and then crack the whip, offering rest periods to three or four at a time who want to spend their break pleasing the whipmaster in special little ways. This could be called "EcoBoobs" or "EcoBooty" (Better still: "EcoBoobsandBooty"!) and would increase Mustang sales at least a thousandfold. I'd buy a dozen Mustangs so equipped myself, maybe more.

And people thought Da Vinci had great ideas. Lame.

My mom's Charger R/T has MDS(Multi-Displacement System) and i've never found any issues with it whenever i've driven it. I personally think its a good system and should be implemented. We still get all of our cylinders and the same power, but some better mileage here and there. I don't see a downside to that if the system works the way it should.

 

Maybe, it does look like it has full VCT and that is a good way to reduce pumping losses IIRC, not to mention Ford is going with M6 and A6 tranmissions and maybe they'll juggle the final drive ratios a bit as well for improved effciency. The bottom line for Ford just needs to be that they can advertise a more effcient package compared to the current offering regardless of what technology they employ.

The M6/A6 transmissions by themselves are probably the biggest fix for the GT/V6 cars. The GT is positively frenetic in 5th compared to its competion (also I suspect one of the biggest reasons Brand X guys claim effciency and emissions superiority over the MOD motor).

 

If it did you would be driving a lawn mower

 

Yeah, but a really nice lawn mower.

 

I agree in every way
