Does this really qualify to use the term "hybrid"?

It is essentially a conventional combustion engine with a regenerative
braking system added.

I wonder what the weight penalty is and then I wonder how much energy it can hold. Like
on a long downgrade where you have to downshift or use brakes, will it reclaim all the
energy used to climb the upgrade or is it just good for one 60-0 stop and ramping back up?

Might be easier to add an extra air tank, than to add more batteries.
Imagine if you go up and down a lot of hills and on and off ramps.
If you didn't need the space you could add a big secondary tank in the
trunk.
