Drive 55 Conservation Project Update 9/11/05

By Tim Castleman

On the 4th anniversary of the tragedies of 9/11/01 I am inspired to provide an update on the status of the Drive 55 Conservation Project because it was born in the days following the tragedy that has since been used to engage the U.S. in military aggression worldwide and suspension of much of our freedom here in the ‘homeland’.

At last gasoline has reached $3 per gallon and this has helped swell the online petition to congress and pledge to obey speed limits, never exceeding 55 MPH, from 69 to 84.  

Visits to the website have doubled since June from about 75 to 150 per day. There have been 34,007 visits in the last 12 months. Maybe when gas hits $6 we will break 100?

A TDI Club member sent in a report establishing a 76-MPG record in part by driving 55 the entire 1,375-mile journey. This is important enough to include as the balance of this update.

VW Beetle wins fuel economy prize: 76 MPG

Hi, I thought this story should be of interest to you. I did drive 55 (52 to 53 true speed) to set this mileage record. I don't recall passing anyone on the entire trip.

Over the Labor Day weekend, the TDI Club had it's annual get-together called "TDI Fest." The club has a large percentage of car efficiency enthusiasts that have chosen diesel technology instead of hybrids. TDI (short for "Turbocharged Direct Injection" is Volkswagen's label for it's highly-efficient automobile diesel engines. 150 people showed up for the three-day affair near Madison, Wisconsin. They were a small segment of the approximately 35,000 club members that have registered at <> . The meeting was about efficiency and also about high performance. With a TDI-powered car, you can definitely have both.

Attendees drove to the meeting from all over the U.S. and Canada to show off their beloved fuel-sipping cars. Cars were entered in a variety of competitions from road rallying to extreme fuel economy.

The fuel economy prize was won by Ernie Rogers from Pleasant Grove, Utah. His winning car is a 2003 VW Beetle TDI. He drove 1375 miles to get to the meeting using just 18 gallons of fuel-- 1200 miles of which was accomplished on just one tankfull (15.5 gallons). His trip fuel economy was 76 miles per gallon.

Rogers' car included several small refinements that added up to the exceptional mileage: a drag reducing device he designed and built himself (pictures at <> ), lower-rolling-resistance tires, low-friction engine oil, and use of a B5 biodiesel blend fuel to increase efficiency and improve emissions.

The hottest topic of conversation at the meeting, and the subject of a popular technical session, was on the benefits of using biodiesel or biodiesel-blend fuels. Most of the attendees were either already using biodiesel or had decided to start. It was noted that research in Canada had shown that a fuel blend with only 1% biodiesel can increase a car's fuel economy by as much as 14% while substantially lowering emissions.

Biodiesel is one of many new sulfur-free diesel engine fuels now entering the market in small quantities. Most of the new fuels (including biodiesel) are not made from petroleum, but from a number of renewable sources. Biodiesel can be made from soybean oil, canola oil, or other seed oils, and from many oily wastes such as animal fats. Low-grade oils and fats that are not fit for use in foods have now found a new usefulness. In the future, we will be able to make renewable diesel fuels from other wastes such as garbage and leftovers from harvesting of many crops including wood.

Diesel engines provide exceptionally high torque at low rpm, as well as 43% peak efficiency, higher than any other type of engine. While diesels gained a bad reputation in the past for high emissions, newly developed engines have overcome the problem, running clean on fuels with very low sulfur content.

Diesel engines naturally emit less carbon dioxide (a greenhouse gas) because of their higher efficiency.
