no it is definitely not passe, they r still the most powerful and efficient engines around, only other alternative is electric motors, they r also being used but mostly in conjecture with ic engines.
storing electric power is still a problem.

The internal combustion engine is definitely not passe. It is still the most powerful energy source for its size that we know how to make.

It isn't true. Even if one uses fuels other than petroleum-based, you still need an internal combustion engine to get mechanical power from a package of reasonable weight and size. (You have to count the fuel tank as part of the package.)

Because gasoline is the only stable and reliable fuel source we have so far created. Hydrogen is too dangerous and costly, ethanol is still not widely available enough to change all the technology, and electric cars still pollute (since we need to produce the electricity for them somewhere, and that is via the power stations).

Currently that is best and most economical and reliable we got.

because it burns oil products... keeping the $$$ flowing to the oil companies
