Hope this helps.

Its not a practical solution.
The clockwork spring would need to be so big, it would fill the car. Also because of the possibility of it breaking when wound up, it would need to be placed in effectively an armour-plated box.
This would make the car very heavy with little interior space compared to a normal car. The extra weight would mean the car would use even more energy to travel any distance than a normal car.
Also, the clockwork mechanism would have a lot of internal friction, meaning that of the energy you put into winding it up, a lot would be wasted rather than driving the car forward.
How do you propose winding it up? It would require a lot of effort for a prolonged time to store the energy necessary to power the car.
Also controlling the flow of energy from the clockwork mechanism to the wheels would be difficult - clockwork toys only work at full speed, but that wouldn't be practical for a car.

Clockwork machines store kinetic enery in a spring, to propell a vehicle at the speed cars travel at would need a vest amount of energy and a person probably doesnt have the strength to turn a key enough to even get an everage 1300kg car off of their drive.
Second of all, and this is assuming you could get it going, you are driving at 70mph on the motorway and you run out of kinetic energy and the car suddenly stops. Pile upsand deaths at worst, having to get out and crank you car up for another 5 hours at best.
In short no, nobody is making a clockwork car not even toy ones. It would be utter crap and you are quite frankly a bit daft for even thinking it.
EDIT: This is something I can see happening on Scraphead.

Not as far as I know, but the Smart Car was designed in collaboration with Swatch!

Leonardo Da Vinci tried but found impracticable.Not able to store enough potential energy.

No, you still need energy to wind the spring where would that come from?

what would happen if it needed winding up on a motorway or you was somewhere and it was rainning fast you would not want to get out to wind it up. sound like a rubbish idea

Thank god for you!! Its about time they did...they would be difficult to wind up, but instead of petrol stations there will be massive winding stations.

Not enough torque at the wheel gear.

is this question a wind up?
