Actually what was non sequitur was the original "don't blame me"conclusion of the quote of the quote. in msg# 6170. Was it terrible the numbers upset the illusion? So while the pew # was similar, the church was entirely different.  I still am not sure why the Prius/TDI adversarial relationship continues. Latest flash on CNBC, the USA has HUGE reserves of other than light sweet crude. The problem is the MOST US refineries are geared to refining light sweet crude. Seems like an upcoming trend will be refined (from light sweet crude ) RUG to PUG will come from INDIA!!!! Not a good time or situation to be a 98% plus RUG to PUG consumer when there is a HUGE abundance of refine able diesel fuel!!! (from other than light sweet crude- and up to 40% cheaper per barrel) |

Replying to: hypnosis44 (Jun 23, 2008 9:09 am) One of the biggest mistakes with a VW TDI is babying it. They like to be wrung out now and then to blow the soot out. If the car is from another state it could be buildup of very dirty diesel. If it was run on dirty diesel then she started using biodiesel mix she flushed some of the crap into the injectors. Biodiesel is an excellent solvent. Keeping a clean fuel filter is essential. With so few VW TDI vehicles in CA it is hard to find a dealer with a mechanic that is competent to repair and advise the owner. Fuel Filters When first using biodiesel it is recommended to replace the fuel filter on your engine. Because of the solvent properties in Biodiesel, it may cause the release of accumulated deposits inside the fuel tank and fuel lines from years of diesel-fuel use. These deposits can flow down the fuel line and may plug the fuel filter. Luckily, most of the time the filter's don't plug all at once, but slowly, causing slight hesitations in engine acceleration, missing (cylinder's not all firing), or other sluggish behavior.

Replying to: gagrice (Jun 23, 2008 10:45 am) We can thank the USA regulatory agencies. The major mistake was not requiring diesel ( D2 specifically) sold in this country for as a min of the last generation (30-40 years) to be ULSD.(to have coincided with the switch from leaded to unleaded RUG to PUG and subsequent lowering to 30 ppm sulfur) So if one bought a diesel before the October 2006 time (delayed cut over to ULSD) frame (with an ultimate 20 year full implementation time) , the most widely form of diesel available was LSD or 500 ppm (or CA 140ppm) This means/meant that one was in effect destined to run a less than optimium fuel, with the inherent problems and issues. This of course played right into the "dirty diesel" scenario/mantra, even as the combination was no dirtier than a Ford Taurus/Honda Accord/Toyota Camry. The real hidden secret which is SLOWLY getting out is that bio diesel not only is cleaner than electric cars and renewable vs non renewable Prius fuel, but consumes C02 in part of the cycle but can be adapted to use waste from ongoing and to be developed processes vs NON for the hybrid Prius. Indeed the extra batteries have been stated by Toyota as being more consumptive in the total life cycle than even SUV's. Another secret hidden in plain sight that is getting out is RUG to PUG is a min of 2 x dirtier than D2  30 ppm (vs 15 ppm) So how would it sit with all you RUG to PUG users to now get it as clean as ULSD to bio diesel? Would stricter regulations and 10-15 cents per gal more for RUG to PUG be in the cards? Goverments have not been inattentive, as the % of revenues has decline with the higher RUG to PUG per gal prices and they will likely be looking to increase both the % and vol of taxation. The decrease (however slight) in mileage has SEVERELY impacted government/s revenues also. 98% of gasser users could give a DARN about this, but another internal truth is ULSD to bio diesel burns FAR cleaner than RUG to PUG. I can run a normal 25,000 mile OCI. So does a 3-5,000 mile OCI use more/less oil than a 25,000 mile OCI?? |

And its a 6, not a V-8 or V-10 Article doesn't specifically mention the US market, but does state that the engine choice is to help avoid CAFE fines that start in 2016: http://www.leftlanenews.com/porsche-confirms-diesel-cayenne-updated-boxster-to-d- ebut-in-january.html

Replying to: roland3 (Nov 19, 2007 7:05 am) the tenth annual engine expo show in Stuttgart Germany. Their revolutionary injector has over *five* times the pressure of the latest common rail systems. Should the reg bodies be looking at the superior carbon footprint of this system, and offering incentives to bring this to market ???

This one will be moving to the head of my list: With the diesels winning the big races Porsche may start using diesels in their sports cars  We have been expecting a diesel engine option for the Porsche Cayenne for a while, and it appears that March of 2009 may be the date. While Porsche purists the world over may be upset over an oil-burner underhood (or under trunk) of any Porsche model, we don't see the big deal. After all, it's not like the Cayenne, despite what Porsche would have you believe, has all that much 911 DNA in it anyway. A modern diesel engine could help Porsche meet new fuel economy regulations for a lower cost than a hybrid, and the diesel V6 engine sourced from Audi should prove plenty capable of hauling the SUV's mass-tonnage around. Though Audi's current TDI six displaces 3.0 liters and is good for 240 HP and 406 lb.-ft. of torque, rumors indicate that Porsche will be using a 3.2 liter version of this engine that makes at least 300 horses. We think that should do rather nicely. http://www.autoblog.com/2008/06/17/porsche-cayenne-i-diesel-i-arrives-in-early-0- 9/ Porsche purists will recoil in horror, but desperate times require desperate measures: The German sports carmaker is developing its first-ever diesel. With the gas-electric Cayenne Hybrid delayed until at least 2010 and fuel prices spiraling ever higher, the company needs an interim measure. The obvious answer, for the European market, at least, is a diesel. It's not so un-Porsche as you might think. The plan calls for using the 50-state-legal 3.0-liter turbocharged direct-injection V-6 from the forthcoming Audi Q7 3.0 TDI. In U.S. trim, the engine produces 221 horsepower and a very stout 406 pound-feet of torque — notably more torque than the either the direct-injection gasoline V-6 from the base-model Cayenne or the direct-injection gasoline V-8 from the Cayenne S and GTS. In testing the diesel-powered Q7, we were pleasantly surprised to discover that the engine pulled very much like a gas-fed V-8, with the quick-witted six-speed Tiptronic transmission compensating for narrower rev range of the diesel V-6. It launches the Q7, all 5,100 pounds of it, from zero to 60 in about 8.4 seconds while returning a respectable 25 mpg. Considering the 3.0 TDI accounts for more than 80 percent of Audi's Q7 sales in Germany, there's little doubt Porsche will find homes for the 15,000 diesel Cayennes it plans to build each year, starting with the European market in March. Meanwhile, the Q7 3.0 TDI arrives in North America later this year. It looks to me like it will be a close call if they offer them in the USA. If Audi & VW are successful with diesels, I imagine Porsche will jump on the bandwagon. Diesel dropped in price over the last week. While gas held steady. Just 34 cents difference now in CA.

Replying to: alltorque (Jun 24, 2008 6:41 am) I think if GM really wants to knock the cover off the baseball (almost literally) in crushing another home run; they will give or support the assignment to Chevrolet Corvette to come up with a twin turbo diesel (Corvette) sports car!! This would be a high speed LONG distance tourer PAR Excellence!! I would cite what Corvette did with a poorly selling "hard top" entry level Corvette, which has morfed into one of GM's quintessential (-my take but I might be WRONG) success stories...the Z06 Corvette. Both of course would face EXTREME resistance from the ( each brands') faithful. My take is the good news if they do not like it, don't buy it. Next, it is not likely for any of those faithful to drive their current selections off a cliff. Lastly it would definitely increase each brand's reach. |
