As an industry participant in the Hybrid market, I have a bit of insight.
I graduated High School in 1990 and the gas prices were about a $1.00 a gallon in America. 15 years later, it is over $2.00. What will the price be in another 15 or even less, say 6-7? I would expect it to go up to at least $3.00 a gallon within 5-7 years, since China is exponentially growing as a market for new cars and there are obviously dwindling reserves. The tale looks grim in 20+ years from now. America will be in dire straights, although Europe will shine, due to their public transportation infrastructure. I am currently a Test Engineer of Battery Systems at Cobasys, see link below.
Back to Hybrids!
Toyota and Honda have lead the market and forced every other automaker to admit that there is profit to be made from the market segment. Ford now has the Escape. DiamerlerChrysler and GM are on the verge of releasing Hybrid vehicles as is every other automaker out there within the next 2 years. This is just the passenger market. Everywhere you look in the heavy duty segment, such as over the road trucks (not as much here), transit busses, Delivery vehicles, etc are also developing Hybrids. Hell, the Military is even getting into the act, which for them is a huge fuel savings! Toyota has said within 5 years (or less) every vehicle in their fleet will offer hybrid drivetrains as an option!
So, every vehicle manufacturer out there is ready to release new hybrid vehicles, which means that soon, the market will be flooded with Hybrids! What will happen once they are there, well I predict that they will then for the most part become a standard part of the vehicle, such as Electronic Fuel Injection has become, such as Anti-lock brakes, air bags, etc. Since the market will be flooded in a couple of years, I would guess about 5 years to saturation and standardization of hybrids as a normal vehicle. About the time gas should hit the $3.00/gallon mark.
I could provide links to reference of these future hybrids if anyone is interested, but I bet if you Google them, you'll find as much as I can or more, but let me know if your interested.
HYBRIDS are here, but are they too late?
Well, if you like Hybrids, you should look at Electric vehcles as well! They are probably economical for most and not that difficult to do.
