Replying to: gagrice (Mar 19, 2006 9:28 pm) Do folks remember that woman rookie almost winning the Indy 500, sans a man's math miscalculation on the fuel MPG????? So say an Indy car gets 4 mpg. A 37% advantage pumps that up to a whopping 5.48 mpg. She would have made history. |

Replying to: gagrice (Mar 18, 2006 5:10 pm) To bring any car, gas or diesel powered to SULEV compliance costs money. I am sure that if you took off all of the emissions systems from any car, the price of that car would drop several thousand dollars. Gassers have had emission systems for years and we have become accustom to paying for them. I believe that a good portion of the yearly price increase in new cars/trucks is related to the increasingly stringent emissions requirements. I feel that if diesels were presented to the public as nice green cars/trucks with great fuel economy, performance, durability and simplicity then they would probably sell like hot cakes.

Replying to: winter2 (Mar 20, 2006 7:57 am) While I understand and actually agree with the point you are making, of which the above is a part, the increase in new cars/trucks (year to year) is really the cost of "SEX". This is in addition to the fact the auto oems want to keep up with the cost of inflation. Generally year to year presents no radical design changes. This would be in stark contrast with say the 2006 Honda Civic vs the 2005 Honda Civic. (next generation) So what you are saying about the "costs" would be true if they were trying to jump one category, i.e., have to meet more stringent requirements. I would make this swag and please note I am no where near an emissions guru, but I would dare say the emissions for the Prius it NOT radically different from the Corolla. However since the Prius engine is smaller and combine with they hybrid action that makes the gasser engine run app 20% less, that is probably enough to let the Prius get the numbers it does.

Replying to: ruking1 (Mar 20, 2006 8:08 am) Many years ago VW put an autostop feature on their diesels. It helped with fuel economy and probably with emissions too. If an autostop feature were put on every vehicle including diesels, fuel economy would improve as well as emissions. As to the emission systems of a Corolla being similar to the Prius, you are probably right. The combustion cycle on the Prius is different and a little cleaner. |

Replying to: gagrice (Mar 20, 2006 8:35 am) On my CRD, the EGR is watercooled and has some electronic controls applied to it. I am sure it costs several hundred dollars as a part sans labor to install it. Talking about EGR valves, my wife's 1998 Chrysler does not have one.

Perhaps this might be hard to graphically visualize but CAFE standards might indeed be instrumental in keeping OUT higher mileage vehicles like the VW TDI and Honda cTDI's.: economy of scale and cost per unit. Any current upgrade to say a Corolla/Civic/whatever type vehicle can be literally spread over hundreds of thousands ie multiples of 100,000) of vehicles. And the cost per unit is FAR less VW and Honda TDI's can barely get traction say over 10,000 vehicles. Now I can really not fault the range of 36-41 mpg I get in the Honda Civic. By most measures I should count my blessings. However since I also have real world experiences with the TDI or more to the point 44-62 mpg AND having a HOOT doing it, I do wonder out loud!

Replying to: w9cw (Mar 20, 2006 11:38 am) Again a very well known but probably unfactored is the 150,000 mile guarantee of the Prius CC vs how ever long for the Walker Muffler one? |

Replying to: w9cw (Mar 20, 2006 11:38 am) When I had to replace the EGR valve on my Dodge truck, the dealer was $30 less than several after market vendors. Not always the case though. I have also found that using dealer PCVs and thermostats worked better than aftermarket vendor parts. |
