“I wonder if there's a point to these small hybrids. The regular Fit already gets pretty good mileage - how much can they really improve it by adding weight? ” - Demosthenes X
Idling stop: Saves gas.
Low RPM torque boost: Improves performance.
Energy recovery: Saves gas and reduces brake wear.
I do not know how the public judge the benefits/cost of sub-compact hybrids. But, Honda’s move is in the right direction. Because of high cost and heavy weight of the NiMH battery, Honda cannot use the electric motor power more aggressively. The industry expects the price of Li-ion battery to come down as low as $220/kWh by 2014-2015. Then, Honda can use more powerful motor and higher capacity battery pack so that its hybrids can go on battery power alone for much longer distance with much better performance. There is nothing wrong with the concept of IMA. It is simple in construction and MT(and dual clutch) friendly.
