Honda et. al. are not resting. While the US Government pours design incentive money into Hydrogen Fuel Cell tech. The Japanese continue to engineer increasingly efficient Hybrids. Their technology is moving fast enough to make the current green car offerings – well… old tech. I would be hesitant to actually own one of these only because it will likely be obsolete on advent of the next generation (kinda like your 5 year old desktop pc paper weight). There will be a new improved engine version always raising the bar or setting the pace every few years. The gains are not incremental. We’re talking double digit percentage economy AND power advancement. Big problem with the Fuel Cell which hasn’t been thought through – There is zero infrastructure to support the distribution of alternative fuel. No way to immediately ramp up a way to store it, make it, transport it, sell it without spending zillions. I’m afraid that our boys (GM / Ford) are on the wrong tack.
