Are there vehicles that operate on BOTH bio-fuel AND electricity?

Question

i know that there are cars that run on biodiesel and cars that run on electricity and gasoline in combination. but what about a vehicle that runs on a combination of bio-fuel (soy, corn or what ever else) AND electricity? does it exist already?

Answer 1

Trains yes (although I doubt there are any that run on biodiesel), but there are no diesel electric hybrid cars yet.

Answer 2

Idano, but appearently it's a d**n fine idea. You'd get along great with my husband lol. He's always talking about that stuff.

Answer 3

I'm guessing no, but I was thinking the other day that it would be a great idea. I wonder why it hasn't been done yet?

Answer 4

i don't think so.

and i think the reason is that starting a diesel engine is harder than starting a gasoline powered engine.

that would decrease the efficiency.

now, if they made batteries such that the fuel engine was off for longer periods, then it might make sense.

but my experience is that the engine turns on and off fairly often, which would not be good.

Answer 5

Diesel electric trains have been doing it for years.
