Idling, peak acceleration and sudden throttle changes are the operating regimes where gasoline engines are most polluting. Hybrid technology takes care of all three. Hybrids can turn off the gas engine when the car's not moving, can borrow energy from the battery to meet peak demand without having to push the gas engine, and can instantly throttle the electric motor to provide responsiveness.
The Prius is an SULEV, a Super Ultra Low Emission Vehicle. It's several years ahead of even California standards.
Glad someone's taking the sporty route. My Prius's drive motor could deliver 258 foot-pounds at 0 rpm if the computer would allow it. Toyota went for conservative design and lightweight parts instead. They made the right choice for proving that hybrids are practical. Now we'll get to see that hybrids are fun;
Oh, and you want to know just how fast a computer can throttle an electric motor? The Honda Insight has a 3-cylinder engine which runs smoothly. The reason it runs smoothly is that the Insight's electric motor changes torque in real time to counter the momentary imbalance from the gas engine. Sort of a software flywheel.

As for electrics, the electricity at least doesn't HAVE to come from a fossil-fuel-burning plant. It can come from hydroelectric power, from wind power, from solar power, or from nuclear power. It at least gives us a choice of what power source we can use, by converting that power source into something universal.
Ultimately, the real problem with fossil fuels is that we're locked into using them -- this is bad because we will eventually run out, and it is bad because we are forced to send our money to folks in the Middle East, some of whom then send that money to terrorist organizations, some of whom then kill Americans.
Electricity, at least, can be created through many sources.

A common misconception. (Score:5, Informative)
Current hybrids like the Prius, Insight, and Civic don't need external electric charging. Their batteries are very small, and store energy generated by braking or excess power from the gas engine if necessary. The economy comes from a couple of things:
1. You get back energy when you brake.
2. Your gas+electric motors combined are approximately the same power output as a traditional gas motor, but you can turn off part of a hybrid when you don't need it. So you've got the power you need for acceleration, but once you're cruising, the extra motor can cut out leaving you using less energy.
3. Your gas engine can shut off at stoplights, since your electric motor acts as the world's most kickass starter motor. (For example, the Prius' electric motor brings the gas engine to speed in less than one revolution)
4. Your electric motor doesn't waste power "idling".
At no point are you ever charging your battery with power generated from a power plant. They really are just more efficient than gas-only cars at the moment.

It's probably not horsepower so much as it is torque. Internal-combustion engines produce maximum torque (and power as well) at some non-zero rotational speed (usually, it's quite a bit to the right on the curve...3000 rpm or higher, unless it's a big-ass diesel). An electric motor, OTOH, produces maximum torque when it's stopped and still delivers plenty of torque at low speeds...and low speeds are what you're dealing with when you're accelerating from a stop. Torque is what gets you off the line, not horsepower.

As far as I know, none of the available hybrid automobiles are doing this. Honda uses a simpler design, where the main drive is a gas engine, with a small electric "assist" motor. The Insight and Civic are never running electric-only, and use their gas engine traditionally. The electric motor acts as a booster to give you more acceleration.
The Prius is more complicated, and allows electric-only driving. However, the main gas engine is still used to directly drive the wheels.
Now, the advent of CVT transmissions has produced some gains in this direction-- but they're not exclusive to hybrids. Because they're continuously variable, the engine rpm can stay relatively constant. My non-hybrid CVT civic has a couple of spots on the tach that it prefers-- somewhere around 2000 for cruising, and much higher for acceleration.
Yes - Impact on the enviornment, but less (Score:1)
However, one way hybrids are cleaner than conventional rides burning the same materials is that they run their combustion engines at a constant "ideal" rpm. All piston engines have a specific RPM where the ratio of pollution to power is smallest. Car engines driving wheels mechanically pollute more and burn more fuel because have to speed up and slow down.
Diesel-Electric trains replaced direct drive combustion and steam locomotives decades ago for this reason.

That's interesting then.... the cool thing about a gas engine + electric motor is that, at 0 rpm, the gas engine has 0 torque, and the motor has full torque... as the RPMs go up, the gas engine gains torque and the electrice loses (up to a point, of course). The two assist each other,
That would make it harder to do a diesel + electric motor combo in the same fashion (both motors driving the same axle) because it would get sucky high-end torque.
Just an interesting story:
Steam locomotives were popular because they could generate great torque at low rpms - no combustion was needed, so the pistons just filled with steam slowly. Gas engines couldn't replace the steam versions because you'd burn out the clutch in no time. It wasn't until the diesel+electric came out that steam faded away - unlike modern electric cars, the diesel drives a generator that drives a motor. No rotational energy from the diesel is coupled to the wheels. Thus, the diesel generates a lot of current at a speed it feels comfortable at, and the electric motor provides the massive torque @ 0 rpm. The generator-motor system acts as a clutch/gearbox.
That system would be as good as the pure electric cars we have, except, of course, that they'd have better range. I wonder if the electric alone works well enough (to the general population), or if the gas engine is really needed to pass at highway speeds...

Third, diesel engines are more efficient than most other internal combustion engines. Those of you that think they are dirty and pollute the air more than gasoline engines are also wrong.

First of all, large electric motor => large batteries => expensive, heavy and takes a lot of space => not suitable for a normal-looking (or in this case, great looking) car. Because if it didn't have large batteries, the range would be very limited - the small gas engine would not be sufficient to keep the battery charged. This depends on HOW small we're talking here, but if it needs to be large enough to basically deliver all the power for the electric motor, it would be wiser, energy-wise, to forego the generator and have the gas engine run the wheels directly, since even the best generators have noticeable losses of energy.
Second, the idea is to have the two engines do what they each do best. The electric motor keeps it humming along the highways at cruise speed (where little power is needed), and the fuel one delivers the power to accelerate (where more power is needed). So you get the best from both worlds.
Finally, Why use petrol and not natural gas or some other alternative fuel, If you make the tank the standard size then you should be able to get around the "not having enough gas stations problem" which holds these types of fuel back? Since you aren't constantly filling the thing up.
The idea seems to be that using ordinary fuel will speed acceptance. No Joe Sixpack will want a natural gas engine if he THINKS there's not going to be a gas station within range wherever he goes. The hybrid car presented in the article is really just another fuel burner with a really impressive miles/gallon figure, so there is nothing more to worry about than what to do with the gas money saved :-)
Personally, I can't wait for this type of car to reach my country, where fuel is $1/liter. If only they'll put this style of engine in a more usable size car (say, one that can hold my family of soon-to-be 5 persons) and still reap the benefits of a hybrid engine. No wonder my country is the place in the world where 33 km/l VW Lupos are most popular :-)

Well, the auto companies (well, really the auto industry) stand to have a more damaged profit margin than the oil companies do. An ICE (internal combuston Engine) based car cost 28cent per mile to run (about 6cent of that goes to gas, the rest is spend on brakes, oil changes and replacement parts and repairs), and electric car cost about 6 cents per mile run, around half of this is spend on charging the batteries, the rest is spent on new motor brushs (At 80k miles) and replacing all the batteries after 4 or 5 years (also brakes, which may wear less if you have regenerative braking, or may wear more because the car has to be heavier due the wieght of batteries.
I think that everybody in a household should have an electric car for driving around town...
Here are 100s of ICE cars converted to electric [austinev.org]
I'd like to see a used car dealership that buys ICE cars with blown motors and converts them to electric, every town should have one....

Regarding the brakes and wear regarding the increased weight from the batteries. In the Toyota Prius, it's 110 lbs. The 1.5 Liter engine with the generator/starter and motor/generator and battery is about the same weight as the V6 engine it replaces. So same weight, but most of the braking is done regeneratively, so brakes are saved from wear.
Since the gas engine is shut down much of the time, and does not waste fuel idling, the recommended service interval (oil changes) is 7500 miles, not 3000 miles most cars get. Think of the oil saved, not just the gas saved. Even with the savings, it has the get up a go of a typical V6 of the same weight.

The Toyota Prius has an 8 year warranty on the battery. It's a Nickel Metal Hydride battery. It is designed not to be deep cycled. Running out of gas and going electric only is very hard on the battery.
The electric provides short bursts of high torque for merging on freeways, climbing hills, stop and go city traffic, etc. Regenerative braking and the gas engine keeps the batteries up. Gently pulling away from a stop sign leaves the gas engine off until you reach about 10 MPH, then it starts using the generator. No gear grinding cranking noise from this one. The best thing about the Prius is the almost silent engine. It's totaly quiet at stoplights and you don't notice the engine when it starts because the small amount of road noise masks it.
In short, I also like the car because I can enjoy my music in it. (Get the CD changer option!)
