Torsion Powered Vehicle

Oh yeeesh ... I'm just trying to picture what cleaning up after the first car accident would look like .... picking up springs everywhere ..... :blink:

I think I'd be less inclined to worry about picking up springs so much as fishing them out of the various bodies they'd impale.

Springs with the energy necessary to emulate the amount of chemical energy in a gas tank would have huge potential for massive carnage.

After figuring how much mass of springs you'd need, figure out how much additional mass you need to properly keep the springs from killing peoplee in the event of an accident. My guess is you'll have to factor an additional 30% mass just for the safety aspect.

My off-the cuff inclination (as someone with a degree in Materials Engineering, but someone who doesn't really use the "large metals" part of it) is that the weight of springs necessary to emulate the amount of chemical energy in a gas tank is going to rival the weight of an entire car.
