chevy volt mule

the "mule" isn't to be offensive, it explains it out in the article


http://money.cnn.com/galleries/2009/...ive/index.html

there are links at the bottom for the actual test drive.

Good find. I'm glad to hear they're still charging ahead with the work on it in spite of their financial troubles.

There's not much about the actual drive in that writeup. I suspect that's because the Volt-powered test mule drove pretty much like any other car, except for the things they mention as being different.

The Volt's electric motor is sized to provide performance comparable to a 250-horsepower V6, said Posawatz, and that seemed about right.

I hadn't read much about the Volt and didn't realize how high a performance level it was at. I guess given its price they want it to have driving satisfaction. Definitely not the car for me.

Why not? Unlike a gasoline engine, you don't have huge efficiency drops from using an oversized electric motor.

Most AC motors keep their high efficiency ratings at relatively low load levels. When you start changing AC frequency and voltage that efficiency peak moves as well.

An electric motor pulling 1hp at 100% load will generate more heat than an electric motor pulling 1hp at 75 or even 50%. That's especially true if you start over-volting the smaller motor to try and make more power than originally specified.

While the electric motor's partial load performance is quite good, it's still heavier than needed if lower power driving is your desire. Also, the transmission components, generator, and backup gasoline engine will all be larger to support that more peppy driving style they've settled on. The battery pack will also be larger and heavier than needed, and while that would give more electric only range if driving frugally, I wouldn't value it. Of course, I'm not the intended market by a long shot since I am focused on TCO.

I'd love a volt but I get this feeling the apartment complex won't like an extension cord from my 3rd floor apartment to the parking lot. It's actually the perfect car for me, other than lack of utility. I rarely drive over 40 miles a day and when I do it's for long trips out of town where the gas engine comes into play.

The trick is to figure out how to take it from one of the first floor apartments!

I can't imagine worrying about the weight of extra performance equipment if it's producing results. That makes it seem like you're morally opposed to the mere concept of weight, rather than interested in it as a means to an end.

isn't it still running around $40k?

that is the biggest factor for me.

make a $20k plug in hybrid and I am all over it.

From that article (last page):

While GM hasn't said, officially, what the Volt will cost, it also hasn't batted aside the common prediction that it will cost about $40,000. Buyers should be eligible for a $7,500 tax credit, so the real cost for most people will be about $32,500.

I thought the $7500 credit was for FULLY electric vehicles.

I haven't done my homework on that one but that is what I have always heard. maybe it qualifies because of the plug-in feature.

Maybe if I put in a small DC motor operating off my battery I could qualify?

I think it has to be a mass production model.
