If you make a car modular and you make the parts such as doors, hood, trunk, roof like large super capacitors as well as other body panels you could put solar panel on the top and use regenerative breaking to have extra range. To power the car use something like rechargable zinc air fuel cells or newer versions of NiZn cells. Also you could use methane fuel cells. Put the motors inside the wheels to save space. Motors could be made more efficient by using rare earth magnets and pulsed direct current. To pulse the dc all you need is a ball bearing swtich. The magnets moving on the rotor pull the metal ball off the switch to break the circuit. This acts like alternating current. Bifillar coils on the motor should also increas efficientcy. Also you can make the coils with a coabalt prayseodymium or rare earth iron core. The motors would act as generators while breaking charging the capacitors. They could also be very high voltage or low voltage by increasing the fillar of the coils. To that I add that you can also lower the voltate in parallel or increase it in searies. Current capacity of coils depends on diameter of the magnet wires which do have to be one piece wire and not braided wires.

I’m not sure that it makes sense to just evaluate supercap cost based on $/kWhr like lithium batteries. Large energy storage is not the appropriate use for such a device; peak power is the right application, so the cost metric should be which solution is the best in terms of $/kW over some lifetime. They might supplement an EV energy storage system, but their primary use should be boost/regen and/or start/stop. So, I do not agree that they have a long way to go. They were never intended for the application this article supposes.

A car is not a good mode of transportation within a house, because it is not a good match of potential with needs. Similarly Super Capacitors, (aka ultra capacitors and double layer capacitors) have far greater POWER potential than batteries but less ENERGY potential. For a long range we need energy potential. If we were to install charging points at frequent stops then we need power potential for rapid charging.

Bus service can presently take good advantage of the power potential of super capacitors. Regenerative braking and hybrid design could also use super caps to effect. They are becoming extremely popular in larger sizes so that Maxwell has recently increased its production of its largest 3000 F super caps. Some feel that future expansion in energy potential and the development of hybrid batteries will come from an exploration of super caps rather than batteries.

a combination of capacitor and battery would make a great stop-gap solution. the capacitor can take more energy faster and trickle it to batteries making regenerative braking way more efficient.

Regenerative braking. Caps may work better that batteries there so you can try a hybrid approach.
