Honda Civic Hybrid
Civic Hybrid owner upset over averaging 32MPG

This past December, the Environmental Protection Agency (EPA) announced that it would revise its fuel economy ratings to reflect current real-world conditions. EPA ratings at the time didn't take into account stop-and-go traffic, cold weather environments or posted speeds of 65MPH or 70MPH currently found today's highways (EPA testing maxed out at 55MPH).

In February, the EPA rolled out its revised testing procedures for 2008 model year vehicles and included a tool on its website that would take old EPA estimates and convert them to the new testing methodology. Not surprisingly, hybrids were some of the big losers with the 2008 EPA estimates.

Popular hybrid models including the Toyota Prius, Toyota Camry Hybrid and Honda Civic Hybrid drop from 60/51 (city/highway), 40/38 and 49/51 to 48/45, 33/34 and 40/45 respectively.

John True, an Ontario, California native, wasn’t amused with the latest MPG mash-ups. True purchased his Civic Hybrid last year when the stated EPA mileage ratings were 49/51. True averaged 32MPG in his Civic Hybrid over the course of 6,000 miles -- even lower than the revised 2008 EPA ratings of 40/55. Consumer Reports also tested a Civic Hybrid in 2005 and averaged just 26MPG in the city.

The poor fuel economy led True to file a class-action lawsuit against American Honda Motor Company. True claims that Honda has misled buyers with false advertising.

"This case does seek relief for tens of thousands of consumers like Mr. True, who purchased the HCH expecting to benefit from its 'remarkable' fuel efficiency, and paid thousands of dollars extra for an HCH that looks identical and performs basically the same as the non-hybrid Honda Civic," said a June 4 court filing.

Even though the suit goes after Honda, the actual party responsible for MPG ratings is the EPA. "I can tell you that the 49/51 figures are EPA numbers, not Honda numbers," said Sage Marie, a Honda spokesman. "Some customers achieve the EPA mpg figures and some don't, as fuel economy performance is a function of conditions, traffic, driving style, load, etc."

Manufacturers have no control over what rating the EPA will give a particular vehicle once it has completed for regular production. It just so happens that hybrid manufacturers like Honda and Toyota have been able to use the inflated EPA scores to entice buyers over the years.

Honda already acknowledged that its Accord Hybrid wasn't up to snuff. Honda promised performance greater than a V6 Accord with fuel economy comparable to a 4-cylinder Accord. Edmunds, however, showed that its Accord Hybrid only managed 23.8MPG after two years and 30,000 miles of driving.

Honda is dropping the hybrid model from the 2008 Accord redesign and instead will go with a 2.2 liter i-CTDi clean diesel.

If you are not happy with your car, just freaking sell it and buy something else.

These are EPA numbers and I am sure nobody gets exactly what the posted numbers are anyway.

I hate stupid crap lawsuits like this. What a waste of everyone's time and money.

I don't think it's much of a crap lawsuit.

Now if he was getting like, 1-2 mpg off... then yeah, it's pretty frivolous. But if he's that far off, and as was Consumer Reports... I definitely think it has some legs to it.

If you paid more for a product based upon it's performance, and it turned out to get less performance... significantly less... than I'm certain you'd be upset as well.

Some people buy hybrids for the "environment". Some buy them for the "status". This guy clearly bought it for the gas mileage, and it turns out he spent much more money for a vehicle that does not deliver the promise of gas mileage.

If they took something that was wrong and used it in their advertising, even if it was someone else's numbers, they're still at fault.

Clearly the EPA needs to review their procedure for testing gas mileage if it's as much as 35-40mpg off.

If their ads specify that it's EPA numbers, then they're perfectly right to advertise that if they so choose. If someone doesn't understand what EPA number mean (or don't) then it's just their fault. Who runs the test isn't relevant so long as it's the EPA that defines the test (unless their contention is that the car's advertised EPA numbers aren't that what one gets with the EPA testing methods). This also is true for Consumer Report values, they need to be specified as the source because they have their standard of measuring that also may not match up with anybody else.

Else it's like suing a computer company for selling a really slow computer that was advertised with some high dhrystone ver 1.2 rating (that it gets). It's a not-so-good benchmark, but it's well defined.

The EPA has been sued in the past, I recall, for having misleading numbers for MPG. I think this is a permanent situation. Anybody recall how those turned out, I don't remember.

Honda can get sued because they advertised the federally tested figures within their marketing literature as a sales point or feature. Billboards were everywhere (I work in NYC) focusing on the fuel economy of the new Civic Hybrid.

But my question is, why would anyone buy the Civic Hybrid after a test drive? I test drove one, it was a poor implementation of a hybrid. The transition between electric to gas was too noticeable, brakes were poor performing, and the accerlation was too slow. The Prius honestly performs much better than the Civic Hybrid, but I still question crash safety along with long term radition effects.

Bring on the diesels for 2008.

The EPA and CARB are working extra hard to make sure that diesel is not viable in the U.S. The new 2007 and 2010 emissions standards for diesels are a huge challenge for automakers and are resulting in more complicated and expensive emissions reduction equipment.

Diesels are able to be popular in Europe because they have relatively less stringent emissions standards, despite the perception of being more "green" than the Americans. The reality is the opposite in this case.

In the past 6 months or so, I have seen a huge increase in the number of old MB 300Ds on the road. You can always benefit from the increased fuel economy by buying a used diesel. The current EPA rules allow for a car to be legal on the road as long as it meets emmissions requirements of model year, I am not concerned of tighter emission controls.

It begs to question the timing of the new diesel restrictions in conjunction with the current GWB administration and rise in fuel prices. Diesel passenger cars currently only have 1% of the market. It would be a greater public service to ban smoking entirely than restrict diesel emissions to the level the US government is.

Particulate emissions have a direct immediate nevative impact on human respiratory health, compared with CO2 which is naturally occurring in our atmosphere and can't even be rightly considered a pollutant, except for if you buy into the global warming hype.

If you believe that CO2 is causing global warming, then you're going to have to explain how CO2 causes global warming since historically CO2 level increases lag temperature increases. I'm having a hard time with that one myself.

As much as I was hoping for some good talking points, the New Scientist article is very weak. There are a few good rebuttals in there, but for the most part the counterarguments in the article amounts to repeated statements that "although there is some truth to their claim, on the balance scientists say that they are wrong". While this may or may not be true, such a weak discussion is hardly worthy being the cover story. Wasted $5 buying it when I saw it on the newsstand too.

European diesel and gasoline is of much higher quality than what they serve up there in the US. Also, diesel engines can run practically unmodified on a variety of bio-diesels that for the most part do not have nasty other particles.

Lastly, the economy is still a large beneficial factor, as well as reduced co2/greenhouse gases. Using the right filter systems/fuel gets rid of most of the rest.

The reality is thus not the opposite, the average american consumes almost twice as much carbon fuels than the average european.

You're right to challenge that, since the exact opposite is the case.

Aside from sulfur content, American diesel fuel has a much lower cetane (a measure of the fuel's resistance to predetonation) count than European diesel fuel. This means American consumers will receive diesel engines that are detuned to account for low-quality fuel. These engines will deliver poor power and less fuel-efficiency than European counterparts.

Your post states that American Diesel cars need to be de-tuned to accept low-quality fuel and have less power. Therefore, this clearly indicates that Europe has higher quality Diesel. Less cetane means that American Diesel is prone to predetonation, which si a bad thing.

So you're equating the antenna for picking up radio waves (doesn't transmit them, only receives them) as dangerous? Or are you suggesting that the fact we have antennas means that there will be radio stations which correspondingly emit radio waves?

I'm not seeing your logic.

Smoking health concerns were specifically covered up by a few extremely wealthy and powerful lobbyists for many years. Saccharine was shown to increase chances of cancer in laboratory rats by independent research. Fen-Phen was rushed to market and received Rapid FDA approval through lobbying

Low level radiation research has been ongoing for a VERY long time (compared with the other things mentioned). None of the research has shown that there is any link between exposure to Radio Antennas and any health concerns. Granted, none of the research has shown an inverse relationship either.

EMI will not affect you negatively, ionization due to scattering/absorption reactions from particles, aka, alpha/beta/gamma/neutron radiation, that will harm you.

Bodies are a very poor receiver of RF energy - especially compared to an antenna.

Car manufacturers don't publish RFI/EMI specifications because it is not a health concern. And automotive electronics and/or power systems are already designed to reduce RFI/EMI so that your car radio works. Hybrid vehicles would be designed to follow similar standards. Not a concern.

But feel free to worry about it, if you wish!

Well...sorta. The health risks of smoking were well known even in the 1800s (and before). Mark Twain repeatedly commented on his disdain for the 'Moral Statisticians' who were "always ciphering out how much a man's health is injured...in the fatal practice of smoking..." Of course, Twain never disputed the health risks of smoking. He was arguing 'big deal', being alive is the greatest risk factor for death (i.e. life is full of risks), and that many people including himself found smoking to be a pleasurable activity with certain social and/or cultural benefits, health risks aside.

Though most ordinances, statutes, and decrees banning tobacco use in numerous places around the world dating back to the 1700s were influenced by religious beliefs that viewed smoking as immoral or sinful, it was viewed as immoral or sinful precisely because smoking was widely believed to be injurious to one's health. Many such laws or decrees in the 18th and 19th century expressly cited health reasons rather than religious or moral. The information was readily available and has been for over a century, but people tend to pick and choose what they want to hear or believe, anyway.

As for Fen-Phen, it was hardly 'rushed' to market, whether from lobbying or other influence. Fenfluramine and dexfenfluramine were developed by a French company (Servier Labs). Fenfluramine was approved in Australia seven years before it was approved in the United States; 1966 vs. 1973. Dexfenfluramine was approved in Australia three years before the United States, 1993 vs. 1996. Dexfenfluramine (e.g. Redux) was approved in Europe nearly 10 years before the United States and was very popular there, but the dangers went undetected in these countries until US researchers at the Mayo Clinic and FDA sounded the alarm.

Within the www.drive.com.au piece, there is contradicting information.

"Three 30 second video clips focusing on the five-star crash safety of Volkswagen's latest Jetta compact sedan are being considered for Australian audiences." But it then later states it scored 4 stars.

While the EuroNCAP appears to be more comprehensive than the United States testing since it accounts for child safety (my principle concern) it does not list the Jetta on the list below, not even as the Bora. http://www.euroncap.com/carsearch.aspx?make=60df67...

When comparing the Jetta vs the Prius, I have admitted in previous posts about being biased to rear seat safety above all other metrics. The Prius does not offer rear torso airbags yet and its safety cage was rated as "adequate" by IIHS vs Jetta's "good."

Take a look at the Motor Trend figures. For rear safety, the Jetta gets 5/5 vs. the Prius of 4/5. The forces exerted on the crash dummies was higher for the front seat passengers in the Jetta, but I would "take it on the chin" to walk on crutches for 8 weeks with a broken femur so there is a reduced possibility of my child being paralyzed due to side impact injury. http://www.motortrend.com/cars/2007/toyota/prius/s...

vs. the Jetta's http://www.motortrend.com/cars/2007/volkswagen/jet...

As you also might not be aware, the Prius only has rear drum brakes in the US, but the overseas models have four disc brakes. The Jetta comes standard with four wheel discs in the US. Why have reduce braking ability in the US, but have it offered overseas?

Notice the roof and door crinkles on the Prius. None are visible on the Jetta. The narrator on the Jetta video also notes how the structure of the Jetta held up well without exhibiting crinkles. But he also states that the femur forces was the limiting factor from making the Jetta "Best Pick."

I do agree, on both parts. The EPA does have to take some responsibility. However, the testing is performed by the manufacturers themselves.

"EPA estimates are based on laboratory tests conducted by manufacturers according to federal regulations. EPA re-tests about 10% of vehicle models to confirm manufacturer's results."

Now are these vehicles the EPA gets off the lot, or are they supplied by the manufacturers themselves. Are these cars "cherry picked", or randomly chosen?

We can get into 100s of conspiracy theories on the subject. The fact remains, the gas mileage is significantly less than advertised and I know if I as a consumer bought it in order to achieve X amount of gas mileage, and I was 10-15 mpg less than advertised consistently, I'd be upset.

I personally have a full size truck. 5.3l of V8 goodness under the hood. However, I don't drive like an idiot. EPA rates it at 14/19 mpg... I get 19-21 mpg driving in Atlanta traffic.

It doesn't take much effort to get the truck up to highway speeds, whereas a smaller engine does take more effort. I've had 4 cylinder Accord, same drive... 22 mpg. 4 Cylinder Altima, same drive... 21 mpg. Twice the displacement, twice the horsepower, almost three times the torque, and I'm very comparable. Why? I don't have to floor it to make it move.

I work in the automotive industry, and most of what you say is correct. The automakers are responsible for doing their testing, according to published EPA standards/regulations, and the EPA does audit some of the results. The vehicles are randomly chosen.

Automakers go through a lot of trouble to optimize the results of the EPA testing - the engine control calibration is routinely optimized to deliver good MPG and emissions results specifically for the EPA tests, at the expense of delivering sometimes poor results at other operating conditions. This is just another case of "what you measure, they will optimize for," and this explains why normally you don't get as good of results as the EPA estimates.

But as mentioned elsewhere, EPA did recently change their tests to be more realistic, so hopefully this situation will improve in the future.

I also do a lot of business with the auto industy and TomZ is completely correct in how the auto industry tests and how they optimize the vehicule to meet epa standards. Remember, as far as manufacturers are considered EPA requirements are first, everything else comes secondary.

In gerneral, the Japanese do a much better job of optimizing, which is unfortunate for us (the consumer) since it is harder to obtain those numbers real life. Before everyone starts flaming back, just remember I'm talking about generalities based on experience and data, and not your specific case. That's also why the OP's big heavy truck can routinely approach the fuel economy of those small 4-bangers. And this is not uncommon in real life.

But on topic, if the manufacturer is testing according to EPA guidelines, then the EPA is the one that should be pressured for a new testing procedure. If the manufacture is not, then they should be held to the fire.

The numbers are very conservative for a person who knows how to drive smoothly. If you drive like an idiot, or spend a couple hours per day parked on a "freeway", you're going to get worse numbers no matter what you do.

With gas prices what they are, I'm spending most of my time on my Suzuki Katana and getting over 60mpg -- and I don't ride conservatively at all, in contrast to how I drive a car. It drives my friends nuts that I spend less than $10/wk on gas and I look cooler than they do in their lame hybrids.

YOu're missing the point, that if you want to take extra measures to be especially fuel efficient, you should achieve higher than the rating, but given the expected actual use of a typical customer, the number can only be useful if meant as a realized goal.

Also, you don't have to drive like an idiot to get worse fuel economy. Some things are just common courtesy, like not dragging your ass when your sitting at a short-timed stop light so at least a few people can get through that light instead of only the two people who felt like accelerating from 0-40 in 25 seconds.

I agree - far too many people are sue-happy these days.

Probably related to the amount of (beneath) pond-scum lawyers there are floating around.

Anyway, according to the article, he is suing the wrong party - Honda did not make the figures.

Also, the mpgs that you see are highly dependant on the eagerness of your right foot - I can get over 40 or under 20 mpg in my motor if I wanted.

If you knew anything about the technology, you would know that this isnt true. A hybrid will get its best gas mileage when maintaining a constant speed. City ratings, and city gas mileage, are not given for true stop and go traffic scenarios. Sitting in the same spot with the AC on for 2 hours isnt exactly MPG friendly.

That's true, however, the Hybrids are based on a fixed reserve of power - the assumption is that the gas engine (and to s lesser extent the braking) will recharge the battery over time. Generally, the Hybrid will have substantially better mileage in short stop and go traffic, but once the charge on the battery has worn out (which will occur relatively quickly in stop and go traffic, particularly if you're in it for hours at a time), you're still stuck with a gas engine. Granted, it's a tiny gas engine, and a relatively efficient gas engine.

However, I suspect that one of the issues is exactly that - driving habits. I'd like to see some research in many many differing driving habits of people (measurable ones) to see exactly what the effects on fuel consumption really is. Pick several stop and go traffic situations - one where you are trying very hard to be right on the person in front of you's behind, one where you let a little more space between you and the person in front of you (aka not accelerating quickly to "close the gap" and one where you just drive very slowly nearly never changing speeds. Then do the same for moderate speeds (30-40) then one for highway speeds (55-75) with all 3 driving modes. The results of THAT study, I suspect, would be incredibly telling, if not completely unexpected.

I'd bet that hybrids are MUCH more sensitive to the style of driving within a given speed than other cars..

close to useless for interstate driving

On my last interstate trip, a 500 mile drive from central PA to Boston, my Prius got 53mpg driving 75mph on the interstate, despite the hilly Appalachian terrain. Even in the dead of winter when the mileage is the worst possible I get 45mpg on the highway. Either way the figures are comparable to the EPA numbers.

Actually, despite the widespread belief, the Prius does its worst when you have to accelerate and decelerate regularly. On city streets in bad stop&go traffic I can average below 30mpg, which is much farther off the EPA figures than the highway values (although still better than any "normal" car in comparable traffic). The Consumer Report figures were likely also derived in a high traffic environment.

Just in case you are suggesting the Prius is not fast enough for the interstate, remember that Al Gore's son got pulled over driving 100mph in a Prius. Basically, other than your brilliant observation that the Prius runs on gas, you don't know wtf you are talking about.

The perception about city mileage for a hybrid is not that it gets better mileage than highway, but that it is relatively much more efficient than a traditional IC engine alone in city driving.

On the highway, the difference between the two technologies is negligible, with differences related to other effects like vehicle weight, aerodynamics, and tire rolling resistance.

Naw, the trick is that to maintain a constant speed on the highway takes surprisingly little actual engine power - I'd estimate less than 20 horsepower for a car the size (and shape) of a Prius. It's tiny gas engine (which puts out 80 hp?) runs more efficiently generating that 20 necessary hp than a 150 hp engine would to generate the same 20 hp.

Parent is spot on. Physics (and mechanics) tells us that an engine puts out it's highest efficiency right at hp peak. The closer your necessary hp (ie "Power Required") is to that peak number, generally, the more efficient the engine will be at generating that amount of power. The fact that the Prius has a tiny engine in it means that on relatively level ground (or some relatively short hills where you need less than 80 hp), the Prius is going to get better gas mileage than any 150+ hp car.

The point of the electric engine is for those cases where your Power Required is more than what the gas engine can deliver - if your current driving condition calls for 100 hp (say accelerating quickly), it has to kick in the electric motor to give you that extra power. However, that extra power kick has a limited supply - when the batteries are done, you don't get that power any more, and the gas engine has to recharge them.

It's the same effect as if you had 2 gas engines in your car - if you can optimize your usage patters so that you rarely need the second engine, just shut it off, and run off the first engine. You'll get better gas mileage than a single engine that provides equivalent power as both smaller gas engines combined - PROVIDED - you optimize your driving requirements for rarely needing the second engine.

The rated mileage on city streets is higher than on the highway for most if not all hybrids. Likewise journalists regularly claim that hybrids get better mileage on city streets than on the highway.

Regarding hwy fuel economy, certainly aerodynamics and such play a role in the Prius' efficiency, but the much mocked small engine gives hybrids a further advantage. If say the Prius' engine were replaced with a non-hybrid one then the hybrid version would still do better, since thanks to the electric motor providing acceleration, you can pair it with a smaller gas motor optimized to run at a constant highway speed. The V6 Accord Hybrid had only negligibly better mileage than the regular V6 Accord because they paired the electric motor with a regular large gas engine, which was kind of pointless (which is also why reviews for the new $100K Lexus hybrid have been so poor).

The Prius gets better mileage than other vehicles in most any circumstance because it's a small, aerodynamic, light weight car. Take the same drive train and put it into a Ford Explorer and it would get much much worse mileage.

Stop and go traffic isn't good for any vehicle's mileage, the Prius is no exception. However the Prius does better than other non-hybrids (and better than most hybrids for that matter) because it has a couple of advantages - #1 it can turn off the ICE when standing in traffic, and #2 regenerative braking makes use of all that energy which is normally just wasted in a standard vehicle.

No, the Prius uses an Atkinson cycle engine which achieves 34% efficiency at only 13.5hp, which is why it is so efficient at highway cruising speeds, a very low hp situation. An Otto cycle engine does not achieve this efficiency even at its peak efficiency. You can find more info at:

http://www.ecrostech.com/prius/original/Understand...

The following paragraph is particularly relevant:
quote:
Ideally, then, [with an Otto cycle engine] we would like to size the engine in a car so that in the most common driving situations, we use about 40% of the maximum power the engine can deliver. Unfortunately, such a car would not be able to accelerate according to our expectations and would not be able to climb hills very well. It takes only about 15 hp to drive a car like the Echo at 65 m.p.h. on a level road and considerably less at lower speeds. But if we gave the car a 30 hp engine, it would take more than 30 seconds to accelerate to 60 m.p.h. and would slow to 30 m.p.h. on a 10% slope. So, the Echo has a 108 hp engine for acceleration and climbing hills. This means that most of the time the power demand is well below the efficiency "sweet spot" and fuel economy suffers as a result.

I was not aware it could change timing, but in any case I was responding to the claim that on highway driving the improvements were merely due to the car being light and aerodynamic. It seems we both agree that the Prius engine has different timing dynamics than a "regular" engine.

I used to get 50 mpg out of a 1990 Ford Escort Pony on a highway trip. Dinky little 4 cylinder as the only power with a four speed manual. This was with myself as the driver and two or three passengers with the extra stuff needed for a couple night stay somewhere. One of the passengers was a baby/toddler while the others were adults. That's a good bit of extra weight added in there.

The interstate I would run on was mostly straight but half the trip was on a hilly and curvy two lane highway. I would do 65-70 mph on the highway and 80-85 on the interstate and I would manage to get the mileage I did with that weight.

I still don't see the use of a hybrid as I would get mileage as good or better than what hybrids get now. That car is no longer in service (RIP)but up until it's death it got damn good mileage especially considering its age. Even with heavy city driving mixed in, I don't think I ever got less than 40 mpg out of that car. I confess that I did not figure the mileage on each and every tank of gas, though.

Getting up to 100 mph is not difficult. The aforementioned Escort was clocked at 110 as well as an '87 Escort with three speed auto that I had. It took a while to get up to those speeds and the engines were rather loud at that high RPM, but it wasn't difficult to do. Yet, neither one of those cars would be considered race cars or powerhouses by any means.

I would be surprised if there is hardly a newer car model in the US which can't hit 100 mph. I'm sure there are a few that can't while there are others which aren't safe at all to get anywhere near that speed, but it would still be possible otherwise.

In my area(Seattle area) Honda has clearly been advertising thier cars as having the posted mileage without stating that its EPA tested. I have seen ads claiming that they are the only company with cars that get 60+MPG and calling themselves the mileage leader. The Prius has even in the past few months been advertised with the 2006 EPA numbers rather than the revised 2008 numbers. If they are doing the same in this guys' location then I would say he has a valid reason to sue since they clearly do not perform that well for most drivers.

Furthermore, the Microsoft campus shuttles are almost all Prius' now, and they average 34-36mpg in stop and go operation(building to building on campus), which I have always been lead to believe was the sweet spot for such vehicles. Thats only slightly more than half the advertised mileage on the window stickers. Deceptive indeed.

Thanks, but I'll take a diesel instead. I enjoy my Liberty CRD, and were I to buy a car it would likely be an older Mercedes 300TD or Jetta TDI. You can easily get 40-55mpg with those vehicles, depending on the model. Plus no concerns about 100k mile batteries.

Not exactly. If you read it, they have not 'proven' otherwise, they are simply saying that such bias in the study they are critiquing is unsubstantiated. That is true, and I am not arguing with it. However I also know that the battery capacity of the systems in use diminishes over time, and that yes, around 100k you will get less and less bang for the buck. The vehicle will continue to operate of course, but your mileage will decline until you get around to replacing the batteries.

Keep in mind that that is assuming average usage pattern. Battery life is based on age and the pattern of discharge/recharge, not on actual miles. So someone who drives one extensively daily for a few years is not going to see the same problem as someone uses one in a more typical pattern over the course of a longer time frame. That is why taxis in Canada can go 250k miles, they are running up that mileage in a very short peroid of time due to the usage pattern. A typical owner will never get 250k miles out of one and have any sort of reasonable battery life left.

The problem with that estimate is that the average person puts about 12k miles on their vehicle per year. For that claim to be accurate, the Prius battery would have to be good for 15 years, which is highly unlikely. As I stated beforehand, mileage is not the real way to measure a battery's lifespan. Discharge pattern and time are. There are no rechargable batteries on the market today that will retain thier performance for 15 years. Roughly half that time is more likely, with some degredation in performance by the 7 year mark.
