Has anyone thought of a small diesel engine for the generator drive. It would be more effiecent than a gas engine would be better suited to run for extended periods of time at one speed. Any ideas? Comments? Imagine cooking your own biodiesel? Heck, you only need 6 gallons to go 340 miles.

I agree

It makes too much sense to do such a thing. More profit for a car company to have us buy several models over time with "new advancements"!

JMHO! :)

PML flightlink has a mini that uses the same technology. It used a gas gen. A cat diesel 15hp gen engine burns .87 gals an hour at max power. Thats like getting 80mpg at 70mph. WOW!

Diesel will appear in the Opel Flextreme (based on same platform as the Volt, but sold as a 4-door hatchback for GMs European market). I think the main reason we won't see it in the Volt is because the US doesn't rely much on diesel due to availability and cost.

Annual fuel savings are well under $500/year with diesel in small cars (like VWs) compared to regular gas. And you can pay anywhere from $1500 to $5000 extra just for a diesel engine compared to a gas engine. In the end, whatever savings you get from better fuel economy is basically rubbed out with the extra cost of the engine and the higher diesel prices.

But I agree. One of the supposed benefits of E-Flex is that the genset is flexible, meaning it can be any number of options. GM should stand up to its promises and deliver more genset options as soon as possible to give customers more flexibility. With a EREV like the Volt, there's not much they can offer as far as options and customization like you can a traditional car. We should at least be able to choose the genset fuel.

Gas
Diesel
E-85 Flex-fuel
CNG/Gas Dual-fuel
Hydrogen Fool Sell
Etc...

So far, it looks like the Volt will be only gas. That's a shame.

A diesel gen set is definetley a possibility for the future, but the first generation Volt will be Flex Fuel. The reasons are that GM wants to sell this car in all of the North American markets including California. To make diesel engines pass the requirements for the the smog laws here require a lot more expense in additional equipment. Also they want to have the car appeal to the widest amount of American buyers as possible. Many US car buyers are till hesitant to buy diesel because it is only offered at a minority of filling stations. It is also more expensive than gasoline.

So for the short term future, to keep vehicle costs down and have the widest appeal, a gasoline powered range extender makes the most sense. In Europe, it will be another story.
