Maybe some sort of started motor with the bendex spring engauging into a sprocket on a drive shaft / axle would be the simplest form of EV hybrid mod we could do. Simple connection to the drive shaft with no drag when not in use. Then run a separate battery and charge when braking. When you get stuck in traffic you shut down the ICE and run the starter when you have to creep.
I played with this very starter issue to creep with years ago.
Theres a BIG problem with starters. Its common to not crank a engine for more than 10 to 15 sec's. The reason being is the comutator (sp?) Gets hot and throws the soder out. As the soder comes out you get dead spots and the brush's wear very fast.
This is what kills alot of drill motor's, saw's and such.
When we creep a car with the starter the amp/current load goes way up. Even if we only do it for a few seconds. Once the starter start's throwing the soder it just gets worse as the conductivity of the cumutator get's worse and worse. Once the starter is hurt it spirals out of control to a very fast death. It also wears on the bendix and starter drive ring or fly wheel teeth. When this happens it can cause a starter bendix to hang. That ugly! A starter dosent last long when spun by a running engine. The smake comes out very fast.
Others in the past have mounted starters or other 12/24 VDC motors on a belt and used them for the same thing or a helper motor if you will. Basicly what idiot GM is doing with BAS hybrid system. At one point you could buy such a system from JC Whitney I think it was.

So where can we get the EPA figures for our vehicles?
Apparently they changed the tests that they used to estamate EPA numbers in 1985, so if you have a car that is older then that it gets tuff, but http://www.fueleconomy.gov/ is the offical site, you can also go to your local public libery and get all the same information in book form published by the same agency.
