Do you not remember the end of the first movie, when he did have the Mr. Fusion (instead of using Plutonium from the Libyans, or electricity from the clock tower lightning strike,) and was stuffing banana peels and beer cans into it, he ended up flying off, not driving off.

Right, but there is a bit of discontinuity. A major plot element of the 3rd movie was the fact that the car needed to get to 88 MPH, and the gas tank had been punctured, so it couldn't be driven. Thus the need for the train to push it.

I shouldn't expect consistency out of hollywood, but that's a big inconsistency.

The plot for III begins in 1955. Marty is using the 1985 DeLorean, not the 2015 Mr. Fusion DeLorean when he goes back to 1855 to save Doc Brown.
