Slightly misleading. Ford & Nissan licensed Toy's 1st gen hybrid technology from the original Prius. The current Prius is Toy's 2nd gen. And obviously an improvement since the car is larger & heavier but gets even better mileage than the original Prius.The article Howell linked to said:Ford and Nissan have both licensed Toyota's technology to make hybrids, while Honda has developed its own system.
We shouldn't even be using internal combustion engines in 2020, but to say we'll only have 5% to 15% of vehicles hybrids (with the rest presumably regular internal combustion engines) by 2020 is laughable. This is progress? We should have been rid of combustion engines on autos for 20 years by now. The technology certainly exists. Exactly what is wrong with straight electrc vehicles powered by batteries for 99% of the real world driving people do? People seldom need to go over 100 miles in one shot. On the rare times they do, just rent a gas car. The limited range thing has been blown out of all proportion by automakers resistant to change.He pointed to independent forecasts that hybrid engines could power 5-15 per cent of the world's cars by 2020.
For the Escape, gas 4 cyl gets 22 city, 25 highway, gas 6 cyl gets 20/25, and hybrid w/4cyl gets 36c/31h (from Ford's site). For those city miles, that's an 80% improvement in mileage over the V6 while maintaining comparable power. Why or how is that dumb? City mileage doesn't benefit that much from Cd, does it? If so, you can apply any Cd changes to both the gas & hybrid versions; both should improve even more. The problem with changing Cd is most aerodynamic vehicles aren't as visually appealing. And while that shouldn't be a major factor when comparing vehicles, it is.jtr1962 said:On the hybrid SUV thing, one word comes to mind here-dumb. You use hybrid technology to try to improve fuel economy on a vehicle which is ill-suited to it. It seems like we forgot what we learned about aerodynamics overnight. If you want good economy start by reducing frontal area and streamlining. On after that does using hybrids make sense. We can design driveable vehicles with drag coefficiencts of 0.08 (maybe even less). Those should be the norm. I'd like to see a Cd of 0.12 or less mandated by law. There is no good reason for boxy vehicles like SUVs.
It's dumb in that vehicles like that shouldn't even be made unless there is a real need for it. You don't see me complaining that an 18-wheeler gets maybe 4 mpg because that's the best you can do given the requirements. If someone really needs to tow 10,000 pounds, drive on a glacier, or drive up the side of a building then I have no complaints about them owning an SUV. For most, though, it's a status symbol and/or a means to compensate for poor driving habits by intimidating other drivers. Ever been on a bike with a wild pack of SUVs bearing down on you? I have and it isn't pleasant. They make little enough sense even in the suburbs. In a large city they make zero sense.Fushigi said:For the Escape, gas 4 cyl gets 22 city, 25 highway, gas 6 cyl gets 20/25, and hybrid w/4cyl gets 36c/31h (from Ford's site).

City mileage is affected somewhat by Cd in that reducing frontal area and Cd can improve mpg by maybe up to 100%, despite the low speeds, all else being equal. Remember that while 30 or 40 mph may seem slow enough to not benefit much from aerodynamics, any cyclist will tell you that there is substantial air drag at those speeds. However, more than anything rolling resistance affects mileage at low speeds, and SUVs are heavy, and have big tires with a lot of rolling resistance. Remember that the auto makers sold the public on SUVs because those were the vehicles they made the most profit on. Given enough marketing, the public can be sold on more sensible vehicles. Also, for urban dwellers who take mostly short trips of 20 miles or less (often way less), the ideal vehicle of choice is the straight electric. It's a damned shame there hasn't been legislation to mandate zero emission vehicles within the limits of large cities. The savings in health care would be worth the costs and the relatively minimal inconvenience.City mileage doesn't benefit that much from Cd, does it?
Again, marketing. The public really has no set taste and can be made to like anything via proper marketing. I'm thoroughly convinced of that given some of the stupid, ugly things which have become "fashionable". I don't think we've ever had a very streamlined vehicle so it would be a completely different look, sort of resembling those human powered vehicles. Plenty that marketing can do with that. I personally think boxy vehicles look disgusting but maybe in part that's influenced by the way their needless lack of efficiency rubs me the wrong way. And from a logical perspective, you only see what the vehicle looks like while you're walking towards it to get in it. I care more about what it looks like inside rather than out. If the average user worries about outside appearances just to appeal to a bunch a strangers while they're driving then that speaks volumes about the superficiality of Western culture. Really, the idea of a car of a status symbol is silly at best. It's to get you from point A to point B.The problem with changing Cd is most aerodynamic vehicles aren't as visually appealing. And while that shouldn't be a major factor when comparing vehicles, it is.
Now here this makes more sense since the form of those vehicles is dictated by their function, and in many cases commercial vehicles are already as efficient as they can be shape-wise because companies who use them care about the bottom line. With the constant stop and go hybrids can increase efficiency enormously. Still, I tend to think for short haul local delivery vehicles straight electrics make the most sense. Buses are probably a natural for hybrids, though, unless we go to something better like overhead power wires (or straight electric if possible for a given route).Think of all the light-duty commercial vehicles like delivery vans, plumbers, the van fleets from utility providers, etc. all going hybrid. The savings in fuel from commercial vehicles would be huge.

Think of what would happen to the economics of the following:
The road we drive on - pavement?
Tires?
Plastic bottles?
CD-ROMs/DVD's?
Milk Containers?
(basically anything plastic)
Cosmetics?
Soaps?
Candles?
The list could probably go on and on.

Doug, it's the burning oil for power part which concerns me more than anything else. The other methods of using oil you mentioned put far less junk in the air than using it for fuel. In fact, all the more reason to conserve oil since it's a finite resource and very useful for something besides fuel (for which there are many other alternatives).Handruin said:Another thing I seldom see mentioned is that cars are not the only thing which require oil.

And the bitter irony is that if one was mass produced, it would actually cost less than a gas-engined car. It's a chicken and egg sort of thing where I feel the government may need to step up to the plate and jump start the EV industry.mubs said:In the last 6 years that my wife has had a daily commute, it's been <= 8 miles one way. I've wished and wished there was an all electric vehicle available that was affordable - we've would have bought it. Now by the time her engine has warmed up, she's shutting it off. Higher wear and tear, lower mileage

Hey Buck-
Keep an eye open for the new Corvette Z06 at your local Chevy dealer. Here's what I know from some people in the know at work: 500+HP hand-assembled V8, under 3,100 lbs., 60mph in approximately 3.5s. Quarter mile in approximately 11.5s. I say, if you're going to burn some oil...have fun doing it!

Sounds very nice Clocker. Here is a good read over at Automobile Magazine. article
Maybe I'm the only one here who thinks in exactly the same way. I stayed in NYC after college despite a smaller variety of job choices for the very reasons you mention. I simply don't wish to be a slave to a car so that means living in an area that offers comprehensive public transportation. Say what you will about it, the subway and/or city buses can take you within a few blocks of nearly anywhere worth going to in NYC except in the borough of Staten Island, often faster than you can drive the same distance, and for only $2 (actually $1.67 if you purchase 6 rides for $10). This is so much better than having to pay thousands to buy the vehicle in the first place, and then often over $1000 annually just to insure it. This is even before you get into fuel and repair costs. Given all the headaches associated with owning a car, it's amazing that such a large percentage of the population has bought into the idea of owning their own transportation. Sure, there are some conveniences, but then again I don't consider door-to-door service to be a good thing since the sedentary American population would be better off walking to subway stations. And then we have the injuries and deaths associated with automobile use thanks to clueless idiot drivers.i said:If not, then why do people still buy into cities where they experience frustration with their transportation options?
I live in Arlington, Virginia. The public transportation throughout this part of northern Virginia, DC, and into southern Maryland is very good.
I don't own a bike.
I also don't own a car. (Shocking!)
Yep. Plain old 21-speed road bike. The funny part with the 65 mph run was that I could have gone even faster but my gearing limited my top speed. Figure that with a 53 tooth gear on the crank and a 12-24 cluster in back, plus a 27" tire, when I reach 180 RPM (about the fastest I can do) this translates to a road speed of 63.9 mph. With that steep downhill plus a 40 mph tailwind I'm pretty sure that even at 65 mph the hill was supplying more than enough for to maintain my speed. Most of my pedaling energy was going right into acceleration. I'd say given a high enough gear, I might have broken 80 mph that day. It was a rare combination of a great hill, a very rare tailwind, and no traffic.RWIndiana said:Jtr, A Bike? A plain, ordinary (perhaps 15 speed) bike? Say it ain't so!
