It's important to remember that the way gas mileage is calculated has been changed substantially for this model year (2008). All cars are going to have lower mileage claims because of the new standards. 21 MPG city is actually pretty good; it's the same as the 4C Camry gets in town. Here is a link to the 2008 fuel economy guide. Read more at fueleconomy.gov.

Every evening on my walk home from work, I cross the giant parking lot of an upscale steakhouse. Something like 80% of the vehicles parked there are typically SUVs. I often watch people parking and waddling into the restaurant.
Based on this extensive and objective survey, I estimate that approximately -- approximately, mind you -- 0.000% of SUVs driven by actual people in really real reality are ever occupied by more than two human beings at any given time.

Chevrolet’s Tahoe Hybrid changes this dynamic with a fuel efficiency improvement of up to 30 percent compared to similar vehicles equipped with a standard V-8.
I bet I could redesign this vehicle to increase the fuel efficiency a few percent. Like make it weigh 1/5 as much.

I actually saw an SUV that was used semi-appropriately today. It was a ten-year-old Expedition with bullbars and enough surface rust to choke a yak. There were no seats left and the trunk was full of power tools. It was effectively an enclosed pickup truck for the workmen whose tools it housed.
Parked in front of it was a brand new Cadillac Hideousity with one occupant idling while talking on a cellphone and smoking.

...it costs less that one dollar to charge the [Plugin Prius]. Its all-electric range includes the first 50-60 miles....
WHA?? My truck gets 25 mpg, so that's around $6 for that distance. If electricity is 1/6th the cost of gas, why aren't we producing gasoline electrically (if we can't have electric cars)?

I saw an ad for this thing in the latest Car & Driver magazine, and I admit, my first thought was that making an SUV into a hybrid was sort of like giving a bull a breast enhancement. But what we have here is a hybrid vehicle marketed to a segment that is most resistant to hybrids... "well, I'd love to save gas/save the environment/decrease our dependance on foreign oil but I need to haul around eight passengers and a trailer..." For these folks, they think "hybrid" means tiny, noisy, and weird. This will go a long way to changing those minds.
Is it perfect? Not even close. But it's a start...
The next step is the plug-in hybrid, like this Volvo effort based on the C30.

They spend all their design money at the ad agencies, which is where all the designers in the country work.
I estimate that approximately... 0.000% of SUVs ... are ever occupied by more than two human beings at any given time.
And pickup trucks almost never carry anything you couldn't put into the trunk of a small car. What's new? Their logic (?) is that they could carry lots of people or lots of stuff, they could go on an off-road vacation adventure running over small animals and tearing up the landscape, that these giant boxes give them some kind of freedom. They need a Civic but they try to buy this freedom the ads are pushing. So they get some big horrible thing for reasons that makes sense for them almost never, maybe just a few days days of the year, but it makes them feel better about driving some big stupid fucker around all the rest of the days of the year.

Yes, jughead, I look at this as further evidence that concern for the environment is a part of mainstream America. Remember, you can't get people to make big changes all at once; little steps are needed. This is a little step.
I would love to see the US government invest heavily in mass transit infrastructure and vehicle upgrades so that fewer people have to drive, but that is not going to happen right away. So we take this little step for what it's worth.

While I would never consider buying an SUV (I drive a Honda Fit that gets 50MPG), I'm not totally convinced that a V8 Chevy Tahoe is such a bad choice as 'green car of the year.'
Someone has to shoulder the cost of developing expensive technologies that will help humans decrease their environmental footprint (although in this case a bicycle would be the best choice). Technologies and special features once found only in high-end, high-margin cars, such as airbags, A/C, CD changers, reinforced autobodies, ABS, etc., are now pretty much normal in economy cars, as automakers have figured out how to do it cheaper by testing out production methods on more expensive cars first.
Still, I often wonder how much CO2 goes into the manufacturing of a new car, versus the CO2 emissions created when driving the car itself.

A pair of Jetta TDIs could get also ~21 MPG (collectively), and they'd have room for 1 extra person in each car.
So, we have an SUV that's as efficient as, uh, two separate cars?

Just to be fair, MPG estimates for Jetta TDI have been revised to a still-excellent 35/44 (5-speed manual; 2002 model year). The new method for calculating MPG for vehicles has resulted in lower stated MPG for every vehicle.

Yes, but in terms of physical mass one USian super-sizing steak-gorging waddler equals two or three regular human beings, so technically those tin tanks are filled to at least half capacity.

i've read that a car produces up to 40% of its lifetime emissions before it's sold. i don't have a cite though, and it would depend on how far it went, how well it was maintained, etc.
but all this crap about fuel efficient behemoths is really beside the point. the problem is not how much gas cars use, but that we drive them at all.
think of the metal and plastic that goes into them; the vast areas of landscape that we pave to accomodate them; the toxic fluids we pour into them (that eventually leak out); the retarded urban planning "strategies" that cater to them - i've lived in LA. i know what happens when you build a city to favour the automobile. the automobile is probably the single most dangerous force in western society. making them more fuel efficient doesn't really address much of their destructive potential.
i own a pickup truck that i drive about once a week. i use it for recreation that requires travel, usually with two people and gear on board, or for moving heavy items. the rest of the time, i walk, bike or bus. my gas-guzzling truck uses less gas than a hybrid driven every day, because i use it as sparingly as possible. most people seem to think that the development of fuel efficient vehicles gives us to be a pass to be stupid and lazy about transportation, but we will end up in just as bad a fix either way. hybrids may just delay the inevitable crunch a little longer.

I think about this point a lot. I live in a medium-sized sub-development out in the country. 100 years ago, it would have qualified as a small, rural town. As such, it would have had it's own school, markets, pubs, doctors, etc. The surrounding farm lands would have supplied the populace with food.
Today, though, we have to drive several miles to do/get anything. I'm not sure that's necessarily progress.

I live in a suburb with very mixed zoning (Levittown, NY), and really, it's only marginally better. I walk to the library, the bagel shop, the pizzeria, but most people don't. These places are a quarter of a mile away--no matter where you live--and yet everybody drives.
While I do think that the really terrible zoning in suburbs in much of the US is a big problem--why should I have to drive 10, 15, 30 miles to go grocery shopping?--I don't think that fixing that is going to get people out of cars. People will complain all day long about traffic and the price of gas, but nothing you do (possibly short of insane, iron-fisted regulation) is going to get them out of their cars.

KokuRyu, what are you doing to squeeze 50 mpg out of your Fit?
Check your gas -- if it's E10 (10% ethanol) that may be the problem right there. Most cars lose about five percent of their normal mileage, because ethanol has less energy density than gasoline. Some cars lose more -- the ethanol seems to much up the mix a bit. I lose almost 10% with my Honda Civic Hybrid and corn gas.

Well, I own a small SUV (97 Toyota 4Runner) that gets about 20mpg in the city. The main reason I bought it is because I live in a rural area where many people live at the end of ungraded dirt roads (including my own). Part of my job is going to people's houses, so it's necessary. In the middle of winter, it's not uncommon to get more than a foot of snow on the ground, and anything less than a 4-wheel drive is going to struggle on heavy snow-covered dirt roads. I also need the SUV because I have to haul around a lot of parts when working. My last car, a Volvo hatchback, got about 25mpg in the city - not much of an improvement, and it struggled when the snow got over 4 inches (plus it cost way too much in maintenance/problems). Not sure I'd buy a Volvo again, but they do well in accidents, if that's an issue.

My last car, a Volvo hatchback, got about 25mpg in the city - not much of an improvement, and it struggled when the snow got over 4 inches (plus it cost way too much in maintenance/problems). Not sure I'd buy a Volvo again, but they do well in accidents, if that's an issue.

I own a small SUV [...] it's necessary.
Hey man, that's cool. I didn't mean to come off sounding like some holier-than-thou prick; I drive a totally unnecessary car because it's fun, for crying out loud. I'm just generally pissed with people who only drive big cars because they can't be bothered to try to avoid accidents (like the small-lady-in-big-truck who likes to make a left turn in front of me 5 seconds after the light goes red because she can't wait for the next cycle). I'd be thrilled to keep them off of the road (as they seem to be the vast majority of drivers).
Yes, 5 seconds, at the minimum. Yes, this happens every day. Yes, it's always a woman in a truck, usually a Lexus RX or a Porsche Cayenne. Yes, this has caused me to drive with both middle fingers extended outside of the car. No, I am not proud of that.

ninjew-Perhaps you should also read How to Lie with Statistics. The raw numbers from the editorial suggest that the hybrid Tahoe still burns 200 more gallons per year than the non-hybrid Civic.
Sure, everyone is free to drive whatever car they want, but the precise point of the criticism is that the environmentally devastating choice a Tahoe owner is making when they choose a Tahoe is not really rationally ameliorated by the switch to a hybrid Tahoe. I agree with the editorial, it is relatively better, but only relative to something indefensible to start with.

Yeah, I see this a lot when I go to the big city. I'm always amazed at how clean all those big 4x4s are (especially compared to mine, most often covered in mud). Out here most people have pickups or SUVs, but it's almost always out of necessity.

I'm not attempting to stand up to the anti-SUV popular opinion. The car I drive now averages about 18mpg. In the past, I'd owned more than a few Civics, all of them averaging in the upper 20s in mpg numbers. I've never owned a truck or SUV, but I wouldn't feel bad about owning one if I had a reason to. In that editorial, he was looking at an average American community where truck use was common, and mostly justified. It's not so much the statistics that I found convincing, it was that these people were going to buy large trucks. They are aware of the consequences of their purchase. Now that they're given a choice, they can opt to use the same type of vehicle while burning less fuel.
That being an average American community, they've got kids and dogs and boats and whatever. If this was 1978, they might be rolling around in one of these. The only station wagons you can usually find now are made by the luxury brands, and mostly they aren't driven by middle class buyers. Well, maybe used ones are. Minivans can haul all the people, but they generally can't tow much of anything. And like someone pointed out above, minivans don't get great mileage overall either.
If I needed a truck like that, and now I'm able to own that type of vehicle and average over 20mpg, while still being able to use it is as intended... well I'd be happy to have that choice.

This SUV gets the same mileage as a Honda Accord. So why isn't the Accord green car of the year? Why isn't the Prius?
Because this SUV sends the right Red State message - you can have it all - fuel economy and the big truck - and you don't have to sacrifice.
The best part about all this is that gas prices do NOT reflect the current price of oil. They are lagging as refining margins are pushed ever lower. Wait until next year and when people start to see $4.00 gas. At that price point people will be sawing off their catalytic converters to squeeze out an extra 10% MPG.

...but only relative to something indefensible to start with.
I've said this before, and I'll probably say it again...but I like my small SUV. I can carry multiple 90 pound dogs, my kid, 800 pounds of raw ingredients or finished product and a partridge in a pear tree. Yay me. So...it's not indefensible. I actually need that much cargo space. Do I need it all the time? No...but I need it often enough that having to go rent an SUV if I need to take my dog to the vet, or need to make a delivery would be stupid.
By the same token, my SUV is almost 10 years old, and has less than 25,000 miles on it...so it's not like I load it up and go trekking cross country with it either. Who could afford that? Good god, the thing gets the same mileage as my souped up old Camaro...well, maybe a little better...the Camaro was pretty rough on gas. And my 64 1/2 Mustang...with a 351 windsor, 10/11 rear end gears and double holley high rise....sheesh, just to crank the engine on that bad boy takes a gallon of gas.
But, ya know, oddly enough, nobody has ever fucked with me when I'm driving the growling monster car of evil death. Nobody comes up and accuses me of "destroying the earth" or raping the planet, or causing global warming...or whatever; whereas I get shit from all sorts of holier-than-thou, leather wearing, dolce and gabbana uniform fetish, Starbucks cup-carrying, pseudo hippies about the SUV.
You know, some of us still live in rural areas. Some of us drive roads on a daily basis that would destroy a Prius...as adorable and cuddly as they may be. Some of us are surrounded by trophy wives in Lincoln Navigators and the only way we can get them to see us through the haze of face powder and botox is to drive something at least as far off the ground. And frankly, my SUV gets about 17 miles to the gallon, which is in line with any minivan and better than most trucks and significantly better than any big suvs.
I'm just saying;not all SUVs are indefensible, not all SUV drivers are blinded by stupidity and false eyelashes, and I'm pretty sure South Park was right about the Smug Factor from the early adopters killing off the willingness of middle America to move into saner vehicles. (For the record, we are replacing one of our trucks with a Prius...we decided we only needed one utility vehicle...but by gods, we actually do *need* that one.)

Why are cars built by Americans so uniquely ugly?
Not necessarily. Sure, some of the new SUV monstrosities are hideous, but there have always been very aesthetically pleasing American cars as well.
I remember sitting in my uncle's brand new black 1977 Pontiac Firebird (he'd shipped it from San Diego to London) in Baker Street while he ran into a store to pick something up. In the ten minutes he was gone, a crowd of about forty or fifty people gathered around the car to gawk at it, oblivious that there was a little boy in there nervously looking back at them. Some of them even took it upon themselves to reverently stroke the car, paying particular attention to the firebird/phoenix painted on the hood. It was the strangest thing.

You're right that crack spreads and refining margins are pretty low nowadays, and it's true that they mean-revert over time, but in the face of a weaker US consumer (and a refining market that tends to clear near marginal cash cost), I'm not lining up to make the bet that refiners do measurably better anytime soon.

DU,
I see what you're getting at, given the conservation of energy and all. So I looked it up. Electricity is not 1/6 the price of gas. Using the energy equivalent for gas of 114,100 Btu per gallon, and gas at four bucks a gallon, I get the electical energy equivalent of 3 cents a kilowatt-hour. So gas is way cheaper than electricity, even at four bucks. It wouldn't surprise me if a Smart is cheaper to run than a Prius.

Hi Mister A,
Not based on any efficiency, just grabbed it from the web and it claims to be an average amount of energy in a gallon of gas. So I converted it to kWh.
I see what you're getting at. Electric motors are more efficient than gas engines, sure.
But most of us pay 10 - 20 cents a kilowatt-hour for what comes out of our outlets, so the efficiency difference would have to be way more than it is, I'm guessing, for this to pencil out.
A person considering this would probably want to know which is more polluting, and that would depend where you live. And then there are the dam fish...
Complicated. I like the Drive Less idea for best guilt attenuation.

1 US gallon of gasoline is good for about 130000000 joules (reference). 130000000 joules is 36.1 kWh, which at 15 cents per kWh is $5.42, significantly above the current price of a gallon of gas.
The exact efficiency difference between pure-internal-combusion, hybrid and pure-electric cars, however, depends on which factors you include in the equation. That, in turn, depends on where you are, and whether you're interested only in what a given vehicle will cost you personally to run, or what it's costing "society" or the environment.
In "typical US driving conditions", about 20% of the fuel energy, at best, ends up pushing you down the road (reference). Efficiency is rather better on the highway - maybe 30% - but falls to zero whenever you're sitting still with the engine running. Hybrids use no fuel in that situation, which is a big part of the reason why they have excellent city mileage.
(There are a few internal combustion cars that cut the engine whenever they're at rest, too.)
Overall drivetrain efficiency for (pure) electric vehicles, in contrast, is close to 90% (reference). Interestingly, regenerative braking doesn't usually make very much difference, since most electric vehicles and hybrids don't have a capacitor bank to rapidly accept the very large power that a serious regenerative braking system outputs.
So, once you've got your gallon of gas or 130000000 joules of electricity into your vehicle, a pure electric vehicle will take you 4.5 times as far on it than a gasoline vehicle will, all other things being equal.
Since the electric vehicle is likely to be light, very streamlined, have low rolling resistance tyres and so on, it could easily go even further - I wouldn't be surprised to see ten times as far - per unit of energy. All of these latter features could, of course, be applied to the internal combustion vehicle too.
If you live somewhere with much steeper petrol taxes than the USA - which is to say, almost anywhere else in the world that isn't full of oil wells - the value difference is likely to be much more dramatic. US electrical power prices are not vastly different from European prices, but petrol in the States is (still) much cheaper than it is in Europe.
But it's more complex even that that.
If you take into account electricity generation and transmission and charging losses (same reference), overall efficiency for pure electric vehicles is less than 30%. That's mainly because electrical power is usually generated in fossil fuel or nuclear plants, both of which use hideously inefficient steam turbines to turn the generators.
But if you take into account losses in the refining process and transportation (vehicular fuel can't be moved down a wire...), the overall efficiency of even diesel IC automobiles starts to dip very close to 10%.

Eletric motors are pretty efficient, much better than 90%. You can see this is true by looking at the cooling systems of large industrial motors. Mostly they have some metal fins, maybe a fan. Internal combustion engines need liquid cooling and big radiators.

I was recently in France, and gas there averaged out to about $8/ gallon (or $1.5 euros/litre - check my math).
Nobody there was sawing off anything. In fact, cars were remarkedly bigger than the last time I visited 4 years ago.
Honestly, I think gas prices could rise to a similar level, and despite all the yelling and crying, most everyone would drive just as much as they do now.

No, but I do think we're all going to stop driving cars virtually overnight, and it won't be pretty. Like most good citizens, I can only hope I'm dead by then.

50 years ago a volkswagen, as well as most other european cars, averaged over 30 mpg. what have automakers been doing for half a century? how can they possibly be bragging about 23 mpg?

Adding safety equipment to keep you alive when the two-ton Tahoe hits you. And power windows, moonroofs, larger wheels and tires, heated seats, CD changers, and soundproofing. Heavier small cars need bigger engines to deliver acceptable performance, which use more fuel. The 50hp 4-banger might have been sufficient for the sub-ton Beetle, but it wouldn't get your 1.5-ton Corolla up the on-ramp anymore.
Modern internal combustion technology delivers more horsepower-miles for a given volume of fuel, but the fact remains that cars keep getting heavier, and engines keep getting bigger.

Interesting. My 1989 Corolla gets the same city mileage as the 2008 Tahoe, according to the EPA's new formula. And I know my MPG highway is higher in practice. 30-35 MPG highway is more accurate, and is what is estimated by the old formula. My actual city MPG is just a little lower than the older estimate, IIRC (low to mid 20s).
It seems a little odd that they chose this one, even if the judges were trying to show progress within SUV models. It's not even in the list of most efficient SUVs for 2008, unless it has really good highway mileage. What is the highway mileage for this Tahoe? I didn't see it in the article.

Why are cars built by Americans so uniquely ugly?
You want eye-searingly ugly, designed-by-Homer-Simpson ugly, you can't beat Ssangyong, the also-ran Korean carmaker. Dear sweet automotive jeebus, they must be eating that import Chinese kimchi that's tainted with parasites and heavy metals.

It depends if people actually use the available horsepower. Most people who bring their Corolla up to 3K before shifting will only be bringing it up to 30-40hp.
50hp is more than enough to get the Corolla up the ramp. It's just that people won't actually use it unless there's another 80hp in front of it.

How much energy is lost during the recharging of the batteries?
It depends on the battery chemistry and the charge connection. The standard rule of thumb for charging small batteries - loose consumer-sized cells, radio control model batteries and such - is that you have to put in 1.4 times as much power as you get out, meaning only about 70% efficiency.
Larger battery systems are generally considerably better; that electroauto.com page gives a figure of 88%, which seems pretty decent for a directly connected charger to me.
If the charger isn't directly connected, you can expect to lose a few more per cent, at least. This is the case for some electric vehicles (the old GM EV1, for instance), which use an "inductive" charger, as seen in a much smaller scale in those electric toothbrushes that you just park in their smooth plastic holder to recharge.
An inductive EV charger has an insulated plastic paddle that you plug into the car. A coil within the paddle inductively couples with a coil in the similarly insulated receptacle, making a transformer that moves the power. The advantage of this is that there are no exposed contacts; the disadvantage is loss of efficiency.
Also, how much is lost when the temperature falls below freezing?
It depends, again, on the battery chemistry, and also on how cold the batteries actually get. For a regularly used car, this may be less of an issue than you'd think, since it's pretty easy to insulate the batteries well enough that they'll still be above freezing after a night in a -10°C garage, yet don't bake when you drive around in summer.
Nickel metal hydride, nickel cadmium and lead acid all have -20°C as their commonly quoted lower limit, but at that temperature you're only getting about a fifth of full capacity. -5°C, on the other hand, is pretty much fine. Lithium ion batteries (but not true lithium polymer, which I think still has a water-based electrolyte) are better for very low temperatures.

Ssangyong
¿Eh? The SUV•RV they show on the home page looks like any other boxy SUV. [pokes at "showroom"] The Rodius, though, yah, that's fugly. And the Actyon's looks odd, although I could see it working as a reworking of the old-school Honda CRX Si.

Much of the inefficiency in modern gas engines has nothing to do with gas itself, and everything to do with marketing.
A Prius cruising at 80mph requires about 31.5hp to keep going in a straight line. Seems pretty thrifty compared to a 325hp-engined H2.
But an H2 cruising at 80mph only requires 78.9hp of it's available horsepower. And if they slow down to 65, they only need about 42.3hp to keep cruising.
Auto manufacturers are putting out engines that are far more powerful than anybody can usefully use, because big numbers sell product. unfortunately, they also mean that the engines are very poorly suited to sitting around and generating the extremely small amounts of power that are actually required to keep a car at cruising speeds.

Well, one does want some acceleration power. And in this mountainous terrain (BC), the ability to go up hills in low gear during icy weather is kind of a bonus.
