Hybrids are not a step forward. It's a step to the side at best and a technological dead-end.
@ 18 city, and 23 - 26 hwy. She loves it. She shops with her mother on
the weekends. Flowers, Groceries, heavy/ bulky items fit well. She never
is stuck in the winter (important in buffalo). I drive a beater neon that
gets 27 - 35 mpg. It gets me to work. I wanted a hybrid Escape, but the
cost premium was on the order of 8k at the time. With a family, and the
desire to enjoy your "personal" vehicles, it cannot compromise on the
functionality that you need. I would get a hybrid for myself, but I drive
@5k / year. My wife's vehicle is the primary vehicle, and get a lot of use.
She cannot have compromises. We will get an Edge next for the room,
no hybrids in that class. We wait for something that will work for our
AMERICAN family...
Electric motors are a great match for a gas engine. The electric motor can take care of low-speed acceleration, and gas engines can be used only at the most efficient speeds and power loads.
Fuel cell cars will also be hybrids. The fuel cell doesn't react quickly to power demands, so these cars need batteries to be usable.
Adding an electric motors and a battery to a car enables an efficiency increase of 20-50%, and this efficiency gain is even higher in stop-and-go traffic. That is a technological advancement; to get equivalent or better performance at a higher efficiency level.
The only question about the usefulness of hybrids is whether the extra costs outweigh the increased efficiency. That isn't a technological issue, it is a cost-of-fuel issue. By my calculations, a hybrid that gets 45 mpg will burn 1666 fewer gallons of fuel over a 150,000 mile lifetime than a vehicle that gets 30 mpg. If we assume gas will cost $3 a gallon or more for the next decade, then a hybrid will save $5000 worth of gas. That's pretty close to break-even now, and if gas prices go up, or roads become more congested, the hybrid powertrain will be worth even more.
Maybe we will switch fuels from gasoline. Maybe that alternate fuel will be cleaner and cheaper so we don't have to worry about wasting it. But, if the quantity of fuel you are using matters, hybrids are a technological advance that will allow you to reduce fuel use, in any type of vehicle, for a fixed cost.

- "The more we are consuming oil that either comes from places that are bent on our destruction or helping those who are ... the more we are enabling those who are trying to kill us," Frank Gaffney, President Reagan's undersecretary of defense. " Gaffney, who heads the Washington, D.C.-based Center for Security Policy, said Americans would embrace hybrids if they understood arguments from him and others who say gasoline contributes to oil-rich Middle Eastern governments that support terrorism.
