Hybrid Drivers Provide Real-World Mileage Data
The hot-selling Toyota Prius averages 48 miles per gallon among over 150 cars from across the country, with most drivers achieving between 45 and 51. The V-6 Honda Accord Hybrid delivers 30 miles per gallon while Ford's Escape Hybrid SUV averages 28. All hybrid owners are encouraged to post their data for these and other cars on the Internet's largest hybrid mileage database.
Reliable fuel economy figures are increasingly important as consumers explore their options in an emerging hybrid car market. Hybrids, like the new Lexus RX 400h, pair combustion engines with electric motors that recharge while driving to improve gas efficiency. "Until lately," said GreenHybrid creator Jason Siegel, "consumers have associated hybrid vehicles with a small niche of fuel-conscious environmentalists, but today's hybrids offer the best combination of high performance, great mileage and luxury features of any cars on the market."
Basically, I floored it when taking off and took the car to the max.
You know what I found, I got 25 MPG in BOTH cases. In fact, I got slightly better milage when I was agreessive. Granted, this was not completely scientific, but it made me wonder about doing more accurate testing. I expected to see a 5-10 MPG difference. To follow up, I drove the last tank at a normal "in-between pace".
I was talking to someone at work about it and they thought that maybe today's engines are tuned so well and change with different environments that it doesn't make a difference. It only makes a difference if you are stopped a lot like in traffic jams.
Anyone in Central Indiana want to join me for some more scientific testing?
Before anyone gets confused, I just want to point out that the Accord hybrid is not supposed to be super-efficient like the Prius. It's the top-of-the-line Accord, and the hybrid power is mostly used to increase performance while retaining similar fuel economy to the slower models. It's quite zippy; IIRC it has better 0-60 times than a V6 Mustang.
It's hard to be religious when certain people are never incinerated by bolts of lightning.
I have a 1978 British Mini (the old ones) and the gas mileage is anywhere between 50 and 60 mpg. Here we are almost 30 years later and we are getting- lower gas mileage?
:)
Granted the Mini does not weigh anything and lacks AC- still. The 1 liter engine kicking out 55HP (in my slightly modified engine) is more than adequate to move such a light vehicle. Add to that a suprisingly roomy interior (it will seat 4 people comfortably despite being only 10 feet long) and a car that will corner like a go kart and you have to ask yourself what the auto industry is thinking. Not to mention being able to park _anywhere_
We have materials today that Alec Issigonis (the guy who created the Mini back in the 50's) could only dream of- lighter, stronger and easier to shape- and yet cars today are far heavier. We get worse gas mileage- sure the cars are more powerful but then again they have to be. I realize some of this weight is the result of safety improvements and the like but it just feels like there has to be a middle ground.

Really sorry, guys. Slashdot sent me so many referrals the whole server went down! I won't be able to get ahold of my host for 2 hours, so please sit tight. Very sorry.

Quite agree. The Peugeot turbo diesel option (same Bosch direct injection technology) keeps setting world records. Their 307 just got 3.49 litres per 100km's (or 81.16 mpg in old money) according to this website. They averaged 1,700 Km per 60 litre tank! Why add all the complication of hybrid technology, or why not couple an engine like this with hybrid technology?
Putting the flaming comment about people lying to make themselves feel better aside, the ROI for a Prius is decent. A Prius starts at about $20K so if someone "downgrades" from a larger, lower mpg car like say, a Nissan Maxima SE, s/he could feasibly save a lot of money.
:-P.
We are getting 50mpg instead of 20mpg, and we no longer have to buy premium gas...we are saving $1200 a year, not counting the lower loan payments for the car we traded in.
I would go on, but I am starting to feel way, way too good about myself
P.S. - I paid under MSRP for my Prius and got it in a week.
Mass carnage was predicted when the double nickle speed limit was dropped. In fact the accident rate WENT DOWN.
There were several reasons for this. N.B., all of these were predicted by the proponents for the change, but dismissed by the safety "experts."
First, anyone with a clue knows that the biggest threat on the highway is traffic traveling at different speeds, not the absolute speed. People tend to stay in their own lanes - and can even comfortably stay in the right hand lane - if everyone is travelling at about the same speed. But if there's a 20 mph range (which was common in the interurban areas of the square states) there will be a lot of lane changes even when traffic is relatively light. At those speeds just tapping a car may be enough to cause the driver to lose control.
Second, a realistic speed limit actually lowered the speed of the fastest drivers. A driver going 20 mph over the posted speed limit doesn't have much motivation to avoid going 30 mph over the posted speed limit. But the same driver at the same original speed, if it's the speed limit, will often stay at that speed.
Finally, these roads were designed for traffic going at ~70 mph. At those speeds the road has just enough variability to keep the driver's attention. At the slower speeds the roads are mindnumbingly boring and the driver's attention tends to wander. You wouldn't think it would make that much of a difference, but I've driven between Denver and Seattle at both 55 and 75 and there is absolutely no comparison. (I-80 thru Wyoming and the Columbia River Gorge still suck because they were long, straight flat segments.)
That's why the death rate went down when the speed limits were raised. The annual death rate is climbing again, but that reflects more passenger-miles.
P.S., the Colorado Dept of Transportation will actually adjust the speed limit to match the drivers, not the other way around. They feel, reasonably, that thousands of drivers will make an informed decision about the best speed for a segment of road. Sometimes their hands are tied because of regulations, but I've seen them change the speed limit on other segments.

Leo,
Toyota is doing what GM and Ford couldn't do. It's letting it's customers help fund it's R&D related to the transition from gas to electric.
Future cars are going to be all electric. That's all there is too it. Why? Simplicity. It takes a great deal of effort to design a mechanical structure that can transmit anywhere from 200-600 bhp from the front of the car to the back. You lose efficiency on the drive shaft, at the transmission, etc.
The end game of cars is going to be where the motors are built into the wheels. The power plant is interchangeable (and inconsequential). When you brake, all four wheels will capture the energy into some sort of temporary energy storage device.
Toyota knows this. The Prius is subsidized R&D. Personally, I think it's a fabulous idea.
I have 700 grams of stainless steel in my left leg that says that the potential price of a motorcycle is much higher than any amount of fuel efficiency.
