Aren't electric cars bound to beat any dragster car eventually? You get max torque instantly.

- xcv123 3y agoDepends on how fast you can release that energy from the batteries. Not as instant. Chemical explosions are rapid.
- TaylorAlexander 3y agoThey could boost with super capacitors.
- The_Double 3y agoSuper capacitors are highly overrated by the general public. They really aren't that much better than lithium ion except for in a very narrow power/time bandwidth.
- TaylorAlexander 3y agoThe comment I was responding to was lamenting the potentially slow speed of chemical reactions in batteries, so I recommended super capacitors specifically for the case where a higher rate of discharge is required. I agree lithium is potentially good enough there, I am merely speculating on solutions in the event that an ultra powerful vehicle really could exceed lithium’s capabilities. As for the general public, I can’t say. I use super capacitors in the power system for my solar powered robot and I love them. Through that experience I have realized they have plenty of other applications.

- acyou 3y agoTo me, this is lacking context enough that it appears to be an automated comment.

- jcampbell1 3y agoDrag cars are slipping a clutch for the first 800 feet or so. Totally traction limited, not torque/power limited.
- js2 3y agoThinking out loud, but it's mostly power to weight ratio isn't it? With batteries currently being less energy dense than fuel, can an electric car be faster? Now there's more to the vehicles than just the energy supply, so I suppose if an electric car could harness battery power more efficiently (i.e. with less weight) than an ICE powered vehicle, it could be faster?
