With regen ability, even after otherwise depleting the batteries, you can use a minimal regen load while cruising to keep just enough charge in the batteries to still be able to use the electric motor for acceleration. This lets you avoid heavy usage of the internal combustion motor for acceleration and instead run it more in its optimal efficiency band. That is, take an hit of couple miles per gallon for a short while while the gas engine is at its most efficient in order to avoid significantly using the gas engine when it's at its least efficient. b& -------------- next part -------------- A non-text attachment was scrubbed...
