could we have cars without electricity

Probably not (except for diesel engines). You need a spark (electrical spark) to ignite the fuel-air mixture in gasoline engines.
And you wouldn't have electric starters (and hand cranking an engine can be a real pain in the αss, BTDT ☺), and you wouldn't have headlights or turn signals, and you wouldn't have built in stereos and radios ☺

Yes, as one said, diesel engines don't require electricity to run. You need them to start, however. The compression is much higher than a car, so hand cranking might be a problem.

college undertaking - like toy autos are often evaluated by utilizing distance, now not time. Ten minutes additionally looks an exceptionally severe standards for a non-battery powered toy motor vehicle. you will ought to preserve the small quantity of rubber band, drop weight or spring potential accessible on that small scale so basically organize the force for extremely low speed. assorted reversals on that undescribed board would be difficult. In that regard, is there a stipulation for minimal distance to bypass and are available decrease back ? If now not, then you definately would organize for in easy terms a rocking decrease to and fro action. additionally, is without delay line trip required ? would a around path be additionally suited as leaving a place and returning to it ? EDIT - i myself like the tailored clock motor theory from Thorsten. A around crank arm from the clock pulling a capstan-variety force on the flexibility axle , coupled with a return stress spring ought to be arranged for the reversing force characteristic.

Yes, we can make cars with compressed air (commercially), liquefied air,fuel cells, ethanol (commercially in Brazil), methanol, bio gas or many others forms of stored energies. We Could make cars with light materials like Aluminum-magnesium (Like airplanes), or carbon fiber, or until fiber glass, which the spent energy by kilometer(or mile), would be smaller, but perhaps the problem is cost .

Yes. We had them.
No, not yet.
Not as we know it today.
We did have steam engine cars that ran on steam, fired by oil boiler. Had to stop for oil and water just like have to stop for gas(petrol).
All other answer are good too.
