True, as a philosophy.
But in the case of the older, less carefully filtered diesel trucks, it IS an indicator of it's danger.

A number of adverse short-term health effects have been associated with exposures to diesel exhaust. Occupational exposures to diesel exhaust particles have been associated with significant cross-shift decreases in lung function. Increased cough, labored breathing, chest tightness, and wheezing have been associated with exposure to diesel exhaust in bus garage workers. A significant increase in airway resistance and increases in eye and nasal irritation were observed in human volunteers following one-hour chamber exposure to diesel exhaust. In acute or subchronic animal studies, exposure to diesel exhaust particles induced inflammatory airway changes, lung function changes, and increased the animals' susceptibility to infection.

A number of adverse long-term noncancer effects have been associated with exposure to diesel exhaust. Occupational studies have shown that there may be a greater incidence of cough, phlegm and chronic bronchitis among those exposed to diesel exhaust than among those not exposed. Reductions in pulmonary function have also been reported following occupational exposures in chronic studies. Reduced pulmonary function was noted in monkeys during long-term exposure. Histopathological changes in the lung of diesel-exposed test animals reflect inflammation of the lung tissue. These changes include dose-dependent proliferations of Type II epithelial cells, marked infiltration of macrophages, plasma cells and fibroblasts into the alveolar septa, thickening of the alveolar walls, alveolar proteinosis, and focal fibrosis.
Not to say at all that gasoline exhaust is not deadly - it surely is. They both kill you in their own special way.
I can just picture one of Rukings great-great-grandkids - "Remember grandad talking about his grandpop? Drove around in a diesel car and he liked it." :-)
You were lucky that time. Next time may not be so good for you. Our mechanic was in the shop with the side door wide open and a vehicle running during a tuneup. When he did not answer to a page we went out and he was lying on the floor. We shut off the truck and called the Paramedics. He did not die. He was very fortunate we got to him when we did. The Prius when its engine is running puts out more CO than an equivalent sized diesel engine. I prefer to smell what is going to kill me, than be fooled by an odorless killer.
Lots of times stuck in a drive-thru lane or at a stop light I get A/C with engine not running.
Since the gas engine of the Toyota Camry Hybrid will shut down at a stop and under some driving conditions, the air-conditioning and power-steering systems are driven electrically and powered off of the vehicle's batteries. This maximizes fuel economy and guarantees that the air-conditioning will continue to operate.

Didn't want to make it easy for a burglar to crawl under the door - opened it just enough to vent but not to allow someone to scoot under...
In any event, wow. Just wow. You were flirting with disaster and the fact that you left the door open a bit, proved you knew the risks! One can hope that you at least had the recirculate HVAC door set on recirculate.

You are holding to the definitions, and I actually agree with those definitions.
But, a common practice is still to create a term called a 'clutchless manual', or a 'sequential manual' that have no clutch pedal.
Again, agree with where you are coming from, but it's still a common phrase (i.e. convention).
I also appreciate that the motorsports bodies are trying to be more clear. Perhaps someday, all the world will be properly aligned with the use of the term. I predict that as BMW phases out 'sequential manuals' for Dual Clutch Transmissions, their trademark will die along with the use of that style of transmission, and nobody will feel the need to use it whatsoever.
On the other hand, we have biodiesel algae which is a NEGATIVE -183 GHG Emiter (produces a LOAD of oxygen and in effect EATS C02. It has a HIGH potential, but low resource use for a energy yield. It will take 1-2% but not take away food producing land (unless one eats algae) to address half of the US demand. It also has the potential for almost SILLY high yields per acre. YET we are STARVING the R& D portion needed to make the necessary break throughs.
YET for the almost boutique quantities of bio diesel on the markets we have expressly prohibited passenger diesel cars that can actually burn UP to B100!!! I am not sure about anybody else, but the messages and signals are chrystal CLEAR.
This thread reminds me of the super bluegreen algae MLM craze a few years back. Wikipedia talks about several cases of human poisoning from people eating that stuff.
This compact premium SUV by Audi will roll off the assembly line with three different four-cylinder engines: one TDI and two TFSI units. All three will combine direct injection with turbocharging, and will feature not only an energy recovery system but also a start-stop system. With power outputs ranging from 103 kW (140 hp) to 155 kW (211 hp), these engines will be as efficient as they are powerful. The basic version, the Audi Q3 2.0 TDI, is scheduled to appear a little later and - with 103 kW (140 hp) and front-wheel drive - will average less than 5.2 liters of fuel per 100 kilometers (45.23 US mpg).
The most powerful gasoline engine and diesel engine, respectively, will be paired with quattro permanent all-wheel drive and a seven-speed S tronic, which switches gears at lightning speed.
The Audi Q3 can tow a trailer weighing as much as 2.0 metric tons (4,400 lb).
You read that correctly. An SUV that gets 45 MPG US. May be time to cash in a few Krugerrands.
I think it comes down to what you are used to.

This is NOT to say there are not diesels. However LSD is no longer available and ULSD to B5 is mandatory. So even with no mitigation, the most it can pump out is 1 to 7 ppm sulfur. Conversely an unmitigated gasser can pump out 30-90 ppm sulfur. The math here indicates from (standard against standard) gassers being 2 times dirtier. to a more likely 6 to 18 times diriter, to a max of 90 times dirtier.
Now our host has indicated there are folks who are allergic to diesel fumes. While I am not in the allergy business, I am sure there are many more times that figure (whatever it is) allergic to RUG to PUG fumes.
That is why I never hang off magazine articles written by writers who really aren't familiar with what they are writing about. The guy was probably not a diesel fan.
In any event, the 45 should be possible with the diesel quattro anyway. I think the guy confused the turbo gasser (also 2.0, but greater than 140 hp) with the 2.0 TDI which has the 140 hp, but higher torque than the gasser cousin. My guess is they put the gas turbo in the FWD, but if it manages 45, that in itself is quite the accomplishment. It will be on PUG no doubt because low pressure turbos come at the expense of a bit of go and mpg.
I still think though, that when people think SUV, they think AWD capable, so that is the vehicle the comment's fuel mileage should have referred to.
Sam
I just had a discouraging thought that VW is famous for on these shores. Not putting diesels in AWD vehicles. We have seen it for years with Jetta wagons and Vans and other syncros. So maybe the quattro has one of the TSFI engines. What is TSFI? Turbo Sequential Fuel Injection? Very blasé acronym in these days, if so. It must be a direct injection to get the higher power and mpg, but no DI designation?
AWD (for my op/ed) is almost total overkill. I would not opt for it, almost under any circumstances. Optioned or not one major issue (not under my control) is if it will pass the CA (mountain) chain control points. I guess as I get closer to the pull the trigger phase I should phone the CHP/CA Trans chain control gurus to get a REAL reading.
Indeed if the 45 mpg is a gasser, it sets up a whole new set of filters. Easily one of the major draws to a Touraeg is the 400+ # ft of torque and the TDI's almost perfect match to CA roads. Not to mention it would get easily 4-6 mpg better than a similar gasser.
But it's not only the fumes - the rattling of the engine drowns out the radio.
I do have to say I sometimes wax nostalgic for going skiing with 7/8 folks in the SUV with full gear. The kids now do it a lot with up to 6 (college friends) in the SUV and with full gear- 2/2/2 seating positions)
Has nothing to do with what the official regulations call it.
It's like all the unofficial nicknames for certain equipment in the military. Everything from 'walkie talkie' to 'the BUFF' become common names for things that have separate, official names.
They are commonly used terms and that is how Wiki picks up on them. Wiki is not official regs and nobody said they were. It is a collection of information that is typically cited elsewhere. So if they follow their own process, they can't technically be 'wrong.' They are usually pretty good about citing sources.
They might be "automatic," but to simply call a dual clutch transmission an automatic transmission (which does not have single or dual clutches) merely confuses the situation.
What does the number of clutches have to do with whether a transmission is an "Automatic" or not? Answer: Nothing.
For example, VW's six speed "shiftable" automatic is a very different beast from the DSG six speed transmission.
So? Both transmissions in your "example" are "Automatic" transmissions.
To call a DSG a semi-automatic does not describe it either.
I don't believe I ever referred to a DSG as a "Semi-Automatic" transmissions, and if I did, I was mistaken. The linguistically correct way to refer to a DSG is to call it an "Automatic" transmission with a "Semi-Automatic" mode.
How is it any less automatic in operation than a conventional automatic?
It isn't, both DSG and conventional hydraulic torque converter equipped transmissions are by definition "Automatic" transmissions.
Both viscous coupling transmissions and dual clutch transmissions can shift completely automatically, and both allow you to more or less run through the gears if you choose.
True; hence the fact that they are both "Automatic" transmissions.
Neither lets you actually operate a clutch...but one does have a clutch.
Incorrect, both transmission styles have clutches.
"Automatic manual" sounds dumb, but it does recognize that the DSG has mechanisms more in common with a six speed manual than a six speed automatic.
Not only does it sound dumb, it is dumb; this construct is a complete contradiction and as such, incorrect usage of our language. That and it does nothing to recognize the mechanical similarities between a true manual and the DSG. One possible (and correct) construct from a language perspective would be an "Automatic Mechanical" gearbox. I'm sure there are others.
Since I didn't read this entire thead, I don't even know why this is an issue, but sometimes I just poke my head in to see if it gets cut off. :P
All I'm trying to do here is to help anyone and everyone interested in speaking correctly to use proper language (from a linguistic perspective) to describe automated mechanical gearboxes. The sooner folks adopt correct language, the sooner things like "Automatic Manual" will be dropped from our lexicon.
http://en.wikipedia.org/wiki/Sequential_manual_transmission
This is most often seen on motorcycles. It allows the removal of a clutch pedal (or lever) from the equation. IIRC, a few cars use a SMT gearbox, though. (literally less than half a dozen in production today, all very expensive exotics)
http://www.mbzponton.org/valueadded/maintenance/hydrak.htm
This is the other version of a clutch-less manual that's still a manual. VW and a few others used similar technologies to get rid of the clutch pedal while retaining a manual transmission. Nobody uses such a system now.
The rest is all some form of automatic. (hence the reason the word "Manual" is missing from their official names)
Except by definition.... No offense, but you're in danger of mis-using a term... about mis-used terms.
"Automatic" transmission with a "Semi-Automatic" mode? Good luck with getting the world to go with that, or with "Automatic Mechanical." I suspect that "automatic manual" will not be "dropped from our lexicon" any more quickly than "four door coupe" will.
It seems to me that any time we try to pin language down within certain parameters, the language goes ahead and changes again. People are both creative and prone to bending rules. We will always have to contend with such things as idioms, regionalisms, patois, and social dialects, not to mention common words that "literally" make no sense.
I look forward to your next dissection of my message. This is fun!
You get the idea. As you can tell I'm not "okay" with a term like that.
Long story short, the DSG is an Automatic Transmission; if one wants to qualify it as a mechanical drive coupling versus an hydraulic one, no problem.
Basically one advantage a DSG offers a- step up in mpg over a conventional "slush box" automatic. It is @ the same "higher cost" (option). Since it is seeing application in the VW line, it might be useful to point out that a lot of VW "slushbox" automatics were problematic (higher % wise) and consumed close to 7 mpg more than a manual transmission. FF to today ,...much is made of the SIMILAR if not the same EPA ratings between a DSG and 6 speed manual.
Now I would swag the 6 speed manual probably has a better RANGE of mpg. In my op/ed, a 6 speed manual transmission is probably still the best pairing.
Dismal Alt Fuel Market Ahead Says JD Power Study (AutoObserver)
Keep also in mind that diesel used to be @ 3%. Meaning it went from 3% to 2% a 33.3% DECLINE. The good news is that ULSD is NOT going away.
To me it shows that despite all this conservation talk low per gal prices, etc that it is just that TALK. They are uninterested in saving/conserving ANY fuel, let alone the like for like diesel models that save anywhere from 20-40%. So that is fine. The policy really hasn't changed. Now they have ALWAYS been serious about raising the price of RUG to PUG. They have achieved that in a full depression. Yet now they are looking for the scapegoats to take the blame for the achievements they have worked so hard for. So now in effect they will enforce both higher prices and @ record consumption. Or was that record consumption @ higher prices? In addition, the ppm sulfur is factorially higher for RUG to PUG (30-90 ppm sulfur) than ULSD 15 ppm sulfur nominally delivered 5 to 7 ppm and bio diesel @ less than 1 ppm sulfur..
US consumption is dropping. 1.6% decline recently. (WSJ). But other countries are increasing their demand for oil, so it's not going to help our prices much, if at all.
So now China's middle class will be the new market for American and European gas guzzlers? I have read in passing that China's middle class is 300 M PLUS. and growing. What is the US's total population 307 M?
Is the American Lung Assoc. as verbal about pets causing asthma as they are about diesel? This book I am reading about dust deals a lot with the rapid increase in asthma. People that study it say pets are likely one of the major causes. As diesel gets cleaner, asthma increases. Kind of takes the bite out of your argument against diesel and asthma.
My wife has no fur allergy but diesel fumes bother her. Different coughs for different folks.
What's that book again? Keep meaning to put it on my list (part of me is afraid to read it!).
Ruking1, the US population is around 312 million. In addition to Chinese demand, oil demand is growing fast in India, Brazil and Saudi Arabia.
