I have been playing with Maxwell super caps for many years, well before Tesla acquired that company.

There is a massive difference between caps that are found in an AC systems and the ones I am referring to.

Compared to a battery, the service life and cycle life of a super cap far exceeds it. If used within spec, it will likely long longer than the product life-cycle it is installed in. So while it might not last forever, the product would be probably go EOL before they die.

Either way, its a promising technology that has a niche application. Do some searching around, it's pretty impressive.

I read a few years ago about the promise of Graphene battery tech that would be able to store and deliver on a scale of 100:1 on the current battery tech. So a Tesla type drivetrain, with "ludicrous" type of torque/acceleration in an SUV with a 30-40K range. Oh, and recharge time is as little as 15 min, because you are not generating heat like a typical battery cell.
That would revolutionize the entire industry.

Seems almost ideal if you ask me when max torque is available instantly, and can be had without complex gearing and transfer cases making it less fragile in the process.

The viability of charging for off-road would present obvious challenges, on vehical solar would not be sufficient.

I took this snap shot of a fully electric FJ being built by EV West. It was still work in progress, but I have driven in a few of their other EVs including the Baja Bug which was pretty sweet.

As much as I enjoy EV tech, I don't think its viable in a true off-road truck right now. Not without a hybrid gas/electric combo where its using electric motor for torque fill, which is already being done in supercars... It would help with power and fuel efficiency in a very positive way (getting off the line in regular driving, tow, crawling)

I'd drive that! Ha
