The generating capability of the motor must be very high to recapture as much as it can. But the real problem is this may translate into hundreds or thousands of charging amps to the battery and most batts can't handle it, or if they do it's very inefficiency. A123 should do much, much better than other technologies though.
> 4. The benefit of "buffering" the engine with a "hybrid drive train" in normal driving has reached urban legend proportions. In fact it does little to increase mpg in most circumstances and may well decrease it. Prius has one of the lowest drag coefficients ever seen in a production car. Then they used an Atkinson engine which gets much better mpg but it has poor peak power to get the car off the starting line and the battery booster makes that engine drivable. The lower drag/rolling resistance and more efficient engine alone already explain essentially all its mpg gains over other sedans.
