Replying to: usbseawolf2000 (Jul 12, 2004 7:39 pm) I agree, my question is where the break will occur? From my perspective the GM hybrid PU will be a failure. The Hybrid SUV's on the horizon may or may not share in the success of the Prius. I would have to get 25-30 MPG in a Suburban size vehicle to consider changing. |

Replying to: usbseawolf2000 (Jul 12, 2004 7:21 pm) I think the auto start/stop will have less benefit, particularly if it adds substantially to the cost. The diesel is more efficient to begin with therefore more difficult to justify expensive nuts and bolts. Wouldn't it be awesome if a computer knows all those information about your car and optimize everything for you on-the-fly? That will save a lot of work for you, isn't it? Can you say, HSD? Sure, no doubt. Lets just fire it with diesel instead of gas. |

Replying to: usbseawolf2000 (Jul 12, 2004 7:39 pm) Not quite. It's clear to this point what the advantages of running a gas-electric are. When starting out with a motor more efficient than a gas motor, the advantages may not be the same. Getting a base-line comparison from the get-go is on-topic. A gas motor burns substantially more fuel than a diesel to begin with, which will obviously have an effect on how you would implement the electric system. My off-topic comment was a joke anyway, but there's a dreadfully thin margin of that around here anyway. Diesel in general is a very good application for trucks and buses that operate most of the days and nights. For passenger vehicles, gas-electric hybrids are a better solution. Diesel is a good application for trucks because it's superior performance and economy are obvious to most anyone. The same can apply to passenger vehicles if the correct engines are used. I think the new Mercedes diesel is proof of that. No reason it can't be improved upon with a hybrid system. We shall see how the higher horsepower hybrids with better performance do on the economy side in the real world. The Mercedes is a heavy mid-size luxury car with quite good performance, rated for 27mpg city and 37mpg highway. That's 7mpg better on both ends than a V6 Accord which is substantially lighter. And slower. |

i admit i haven't read all the pages of posts here, but has anybody mentioned the possibility of a hybrid-diesel? That's what I'm waiting for.

Replying to: qbrozen (Jul 20, 2004 5:24 am) I'd also like some diesel facts... like real-world spreadsheets (ongoing collections of actual MPG data). Having other facts, like maintenance costs and compression loss after 200,000 miles would be beneficial too... since without stuff of that nature helps support the "reliability" claims. JOHN
