239 MPG Car

Kozmik writes "VW/Audi has a history of being a leader in creating super fuel efficient vehicles. They currently sell the most fuel efficient car in the world, 3L Lupo and the Audi A2, and the most fuel efficient station wagon (Jetta TDI Wagon). Now VW is experimenting with something along the lines of the Honda Insight ( a 2 person vehicle ). The 1L VW concept car can achieve .89L/100kms or 239MPG. With Biodiesel and Ultra low sulfur diesel becoming available, hopefully more of these vehicles will come to North America. These fuels are already available in Europe and combined with the new catalyst technology they use, these new engines produce very low emissions." It's nice to talk about alternative fuels, but I have yet to see a gas station selling one of them.

      Having worked for an oil exploration company (Unocal), I know that this is already done. The efficiency with which existing wells are tapped is much higher than it used to be. Unocal does mostly off-shore work in the Gulf of Mexico, off of Indonesia, and some exploratory work off of West Africa (with smaller operations in many other locations), and I remember talking to some of the engineers about the process.

      Some of the initial investigation is done using sounding from a boat to check out the sea bed and the underlying geology, and they usually return four reels of tape that contain more than a terabyte of information each. This is then run through computers to determine the true geology to great detail, and if it looks like there's a possible profit to it, further work is done to investigate whether a drill rig should be put into place. This is not a lightly-made decision by any means; these rigs can take more than a year to construct and are very expensive to operate. Every single one of them uses the latest available technology, so no two platforms -- even in the same field -- are quite alike because they are usually started at least a few months apart, and the state of the art advances even in that short time. Rigs are left in place until the very last possible barrel of oil has been extracted, and sometimes longer than that if a possibly promising new technology that can be refit to an existing rig becomes available. These rigs also are the endpoints for more and more wells, sometimes covering hundreds of square miles for a single rig with wells going off at all angles, decreasing the cost for tapping a given field.

      Once a rig is no longer useful and there's no immediate hope of re-use, its wells are capped (though the caps can, of course, be removed later), the rig abandoned, and either scrapped or scuttled. If scrapped, the materials get reused, and if scuttled, the fish get a new home and place to play.

      Much research is now going into investigating the heaviest crude oils. This stuff is thick beyond belief, and almost impossible to pump with current technology. Oil companies have been investigating how to do this for the last 25 years or more, starting around the energy crisis of the '70s when OPEC flexed its muscle, and have made some progress, but it's still not a profitable field at this point. I remember reading an article long ago that suggested that the US is sitting on a virtual sea of this ultra-thick oil that could allow for total domestic consumption, but because it can't be pumped, it sits there, waiting for the day when we get advanced and/or desperate enough to do something with it.

    This was a concept car which isn't much more than a motorcycle on three wheels with a cockpit rather than a fairing. However, VW is a big name in fuel efficiency. The Lupo, a production car, needs less than 5l/100km, or close to 50mpg, and that with a top speed of 199km/h or about 120mph.

    Diesel is more fuel-efficient, but it's also burned less clean than gasoline. Diesel motors release particles into the air which are higly carcinogenic. Only very recently have there been trends to install filters in the cars which accumulate these particles and destroy them every so often. Some car manufacturers refuse to install them since the filters, in turn, decrease fuel efficience - but just by about 0.1l/100km, so that shouldn't be that big a deal. Anyway, without these filters, Diesel engines are not that great, environmentally.

    Tyro,

    Let me address your concerns one by one.

    1. The engine being noisy and dirty are things of the past. Modern computer design has improved diesel engines to the point that the clattering sound you hear from old-style engines no longer exists on a 2002-manufactured diesel engine. As for the air pollution problem, the use of modern fuel-delivery systems and modern particulate traps/exhaust catalysts will eliminate the unhealthy exhaust of diesel engines of the past. The only reason why diesels aren't common in the USA is the fact Diesel #2 fuel sold in most of the USA has sulfur compound levels of around 2,000 parts per million, which will quickly corrode fuel-delivery and exhaust emission control systems on European market diesel cars in very short order. Fortunately, with the EPA mandating low-sulfur diesel fuels very soon, we will see clean-burning diesel engines in the US market in a few years.

    2. Finding diesel fuel pumping stations is fortunately not as bad as it used to be, thanks to the fact diesel engines are very popular for pickup trucks.

    3. Because modern diesel engines don't have the vibrations of older-style engines, you don't have to worry about engine vibration causing long-term structural damage to the car. The current 90 bhp TDI engine on the VW Golf/Jetta is quiet enough that you really for the most part can't tell if it's a gasoline or diesel engine. I can't wait for VW to bring over the PD 130 diesel engine with its 130 bhp output and massive initial starting torque.

    4. Modern diesel engines have pretty much cured the problem of not being able to shut them off on high temperature conditions, thanks to modern fuel delivery systems that have automatic cutoff.

    I for one want to see Toyota build a Prius with a 1.0-liter turbodiesel engine instead of the 1.3-liter gasoline engine. Instead of getting fuel mileage around 50 miles per US gallon try getting fuel mileage in the range of 70 miles per US gallon! :-)

    You are quite obviously diluted and misinformed when it comes to automotive safety.

    Your low-tech, oversized SUV has a ladder frame chassis. This does not compress when in an accident. A car with crumple zones (invented by VW, BTW) will absorb a huge amount of the collision impact leaving only a minimum amount for the human occupants to absorb. Whereas your BODY will absorb this force in an SUV collision.

    Guess what is the leading cause of high speed collision deaths? Nope.. not intrusion into the passenger cabin - Its your internal organs coliding with your skeletal system - This force is magnified several times when in a ladder-frame SUV, so you guessed it - your dead, while your buddy who is driving a CAR in the same accident would survive. Food for thought.

    Also consider the government warnings on the sun visor of your new SUV? Yes, they are true - your SUV *WILL* flip over (and probably kill you from being crushed) if you make sudden turns or collide with a curb. Again, in the SUV - your dead. In a car, your alive.

    An SUV derives all it's structural integrity from that antique ladder from chassis, while a car gets it's strength from the design of the unibody shell. With newer supercomputers working to design more rigid monocoque car bodies, it's no wonder a car is so much safer in an accident than an SUV.

    And lets not forget that 50% of safety is *AVOIDING* the accident to begin with. Who do you think can avoid an accident better? An SUV with very antique primitive suspension, and therefore awful handling (and prone to flipping over) and brakes that are not very effective because they have to stop such a large mass, and huge blind spots that prevent you from seeing smaller cars around you -or- a car with a modern suspension so it can handle well, brakes that can stop it in a shorter distance, and good visibility in all directions? Sorry buddy, you lose again. In an SUV, your dead, in a car you'll live.

    Not safety related, but any self respecting slashdot geek should appreciate modern technology. An SUV does not deliver in that department either folks. That live rear axle was invented around the year 1900, while that leaf spring suspension came unchanged, from the covered wagons of the 1860's.

    Regression period 1994-1997.

    The Cato article does state that other sources do show that light trucks increase the fatalities of other drivers in head-on and side-impact collisions, and that light trucks have an higher incidence of roll over. They seemly ignore this and suggest that the improvement in overall traffic fatalities is due to the stiffer construction, vehicle weight, more safety features of SUVs!

    The study is doing what good studies do: present the counterarguments first. The confusing thing is that the study concludes that while both of the above statements are true, the increase in fatalities they contribute is outweighed by the decrease in fatalities due to the construction of SUV's:

    The strong light truck effects in the case of single-vehicle fatalities imply that the stiffer frames and greater weights of light trucks are protective of life in collisions not involving other vehicles. Moreover, the light truck effects substantially offset any fatalities from increases in single-vehicle accidents associated with light truck use. The multiple-vehicle fatality equations imply that the protective effects of light trucks to their occupants outweigh any increase in fatalities associated with an increase in multiple vehicle accidents due to light truck use and any increase in fatalities to occupants of other vehicles.

    They even suggests more SUVs! This ignores two decades of vehicle improvements (air bags, anti-lock brakes, side impact beams, superior crush zones, increased vehicular weight) and improvements in driver behavior (more DUI stops, seat belts, child safety seats, etc...). By concentrating on percent light truck versus traffic fatalities a really incorrect picture is drawn. Just crash various light-truck versus various cars and cars versus cars from the current years and look at the results - oh just wait the NHTSA and insurance institute equivalent have done that comparison and guess what they reported.

    Once again, 1994-1997.

    It's amazing that a think tank that does such a shoddy analysis can reject years of actual crash tests by governmental organizations and private insurace research groups. I'm not saying that my critique is perfect, but their methodology is pretty goofy. I tend to trust actual research.

    Take a look at the controls in this study:
    • Light truck and SUV registration per licensed driver
    • Dummy variable identifying states with 55 mph interstate highways
    • Average inches of rain
    • Inches of snow
    • Proportion of licensed drivers who are male and under 25 years of age
    • Proportion of licensed drivers who are are over 60 years of age

    and a bunch more I'm too lazy to list. These are two Ph.D's in Economics at Rutgers; we're not talking community college here. You're saying we shouldn't trust academic research? I realize I didn't make it perfectly clear when I posted, but Regulation was simply the magazine that published the study.

    Consider the study. What if it's right? If it's right, then opposing SUV's can cost lives. Of course, any choice that anyone makes can potentially "cost" lives; the point is, what public policy goals are we going to pursue, and do the choices we make further them?
