Diesel Drivers Report Higher Fuel Economy Than EPA Rating; Hybrid Lower

WASHINGTON, DC -- Diesel-powered vehicles deliver more real-world miles per gallon than the numbers on new-car window stickers currently indicate, according to the U.S. Environmental Protection Agency's "YourMPG" database. The findings were detailed in EPA's "Final Technical Supporting Document" accompanying the agency's new fuel economy labeling rule released Tuesday.

The "YourMPG" data, compiled by the Oak Ridge National Laboratory, includes 221 diesel drivers measuring their own fuel economy and providing their real-world MPG to an Internet database. EPA then compared this real- world data with the projected fuel economy calculations it requires for all new cars.

"As can be seen, diesels appear to perform the best with respect to their label fuel economy, outperforming the label by 4.3%," the EPA technical support document said. Diesel was the only power source to see an increase in real-world MPG. Gasoline cars decreased by between 1.4%-1.7%, while hybrid owners saw their real-world mileage drop by over 8% compared to the current fuel economy label.

The link provides complete information about the new EPA test that will on average drop car fuel economy 12% in the city and 8% on the highway

Rest In Peace, old friend, your work is finished.......

If you want on or off the DIESEL "KNOCK" LIST just FReepmail me........

This is a fairly HIGH VOLUME ping list on some days......

A hunting buddy of mine has a Dodge cummings diesel. He got a 2 MPG increase just by replacing the air filter with a K&N performance filter.

Cool! I'm sure the extra breathing room will be included on future diesels.............

I got similar results on my gas Crown Victoria. Good product.

He'd get even more by increasing the diameter of the exhaust plumbing and removing the muffler as well.

Diesels don't like air restrictions.

Diesel contains more energy per gallon, because it is denser than gasoline. It would be stupid to compare diesel fuel consumption to gasoline on a volumetric basis.

What about removing the catalyctic converters? Heck I don't even know if Diesels need cats...

Thanks for the air filter tip, Hydro! Will be sure to check out those filters this weekend. I drive a Toyota 4 banger diesel. It averages 38 mpg. around town and 43 mpg. on the highway. Diesel fuel costs more in Oregon than most states. But I figure to save more money as I drive. My Toy is paid for and goes up in value every year. I figure it still has another 500,000+ miles to go.

E85 ethanol contains much less BTU's per gallon than gasoline, so is it also stupid to compare gas mileage of E85 vehicles to those of Gasoline vehicles?

If the price per gallon is similar (only the recent low sulfur requirement has caused a divergence), the mpg comparison is still valid.

Yes!

The mpg comparison is not valid. The cost per mile is; however, the old higher sulfur diesel put out more pollution which is an externality. A proper accounting of their relative economic efficiencies should take include external costs like pollution.

the amount of pollution emitted by a vehicle is a function of the vehicle, not the fuel.

A modern Diesel (even burning 2005's higher sulfur fuel) puts out way less pollution than a 70's gasoline powered car.

Diesel emit no CO and much less VOC's than even an 80's car.

The Pollution of Diesels is soot which pours unregulated from MD-80's by the ton with no-one dropping dead at the airport because of it.

My Liberty CRD is rated 22-26 mpg. I actually get 30 mpg on the road.

That's why everyone is looking forward to Honda's new I-4 and V-6 turbodiesel engines coming in 2008. Imagine on a Honda Civic getting around 46-47 mpg on freeway driving with no loss of power compared to the current gasoline-fuelled engine.

If you don't mind letting a little more dirt into your engine. K&N filters just don't filter as well as good paper filter elements, especially when freshly cleaned and oiled - as they pick up dirt they actually become better at filtering, although also more restrictive.

I have a 2005 CRD and get similar mileage: 22 in town, 28+ on the interstate. I'm pissed I can't buy a Diesel 300 or Charger or a 1500 truck.

Stupid emission laws that allow gross pollution, but bar economical cars from being built are killing the diesel car.

Diesel cars with European emission limits (If it's good enough for them...) would be a huge step towards energy independance for the US. But noooooooo.

Just be sure not over oil the filter when you clean it. The extra oil will gunk up your air flow sensor.

However, due to complaints from countries with lots of high mountains (Switzerland, Austria, and the Czech Republic) about diesel exhaust causing serious pollution problems in mountain valleys, the Europeans are changing their diesel emission standards to equal that of the EPA Tier 2 Bin 5 from 2010 on. That's why we're seeing next-generation diesel emission controls in Europe such as DaimlerChrysler's BlueTec system.

Yawn...

That's 4 years we could be buying and driving Diesels that meet the current Euro specs.

If you are worried about Diesel exhaust, work on banning Trains, garbage trucks, duramax, powerstroke and Ram quad cab duallies and 18 wheelers. Good Luck.

What's interesting is that European automobiles companies are seriously working on cleaning up diesel emissions as I type this. Expect new European cars to be fully compliant with the Euro 2010 standard for diesel emissions by 2008 at latest. Why do you think DaimlerChrysler spent so much money working on the BlueTec emissions control system?
