(Not a hybrid, but will be Hybrid competition if they bring it to the USA)

Accord Diesel, 2.2 liter engine, 92 miles per gallon on a 419 mile run....Amazing !!

Wayne, did you recently spend some time in Germany?

Keep in mind that this 92 mpg is using the UK gallon, which is 1.2 times the size of the US gallon. Adjusting for that difference, it's about 76.6 US mpg, which is still outstanding.

OK, so that 52.3 MPG rating UK converts to 43.5 US MPG. So they got 76.6 out of a car rated at 43.3 mpg. That's over 419 miles, so they had to be using some sort of special driving technique, no?

Not bad, but still not world shattering. And who wants to breathe those diesel fumes? They make me nauseous.

The special driving technique is that it was mostly downhill.

Hi Lars-ss:

___How I wish! If they would allow that car here, I bet most of us could darn near average 75 mpg (US) let alone a one time record mileage run

___I have been watching the Accord iCDTi’s development and implementation for well over a year now. It is based off the TSX (slightly smaller) and is a bit more slippery (.26 Cd) then the std. Accord sedan/coupe (.30/.29). The only issue I have is that it is the first mid/high performance consumer based diesel with an all-aluminum block. Honda designed it with just a 16.x:1 compression ratio and I am sure that low a compression ratio had something to do with the blocks makeup. It is the superior all-around performance with the high fuel economy that impressed me however … It is only Euro III spec’ed as far as emissions are concerned so it is far dirtier by comparison to any hybrid.

___Anyway, to bad for us poor blokes that it isn’t available in here in the States as I would own one in a heartbeat

___Good Luck

A TDI is able to do north of 90 mpg (US) on a closed course too, it's not earth shattering.

Diesel fumes?

New diesels don't smoke nor they smell.

They have become as quite (if not more) than gasoline engines.

The low cr will allow more boost, thus more torque xcel.

Are you selling your insight in order to buy a diesel? Never know....

Different and efficient by choice!

Wayne, in regard to this:

the Honda Accord diesel 2.2 is actually Euro IV rated - I noticed that on a UK Honda site yesterday.

Another site compared the emmisions to a Prius and showed that the Honda was at 143 in one of the categories as compared to the Prius which measured 104 on that measurement (can't recall what it was) but that shows again, like you said, that the Hybrid is cleaner.

Hi Lars-ss:

___One of the iCDTi Honda design managers posted a small piece on the web about the iCDTi’s emissions. It had a NOx emissions rating in g/mi of .28. This does not meet the Euro IV spec of .25 g/mi

___In terms of CO2, it is directly proportional to the amount of fuel you consume. A car that gets 40 mpg whether gasoline running a hybrid or std. ICE will output the exact same amount of CO2. There are CO2 emission refining differences between gasoline and Diesel which never show up in the figures but diesels always run lean so that helps on their side of the equation. I can’t go into any more specifics because it has been a long while since I was well versed …

___Rammstein, the Accord iCDTi broke 19 world records right off the lot with nothing more then a roll bar and communication gear for an automobile and engine in its category/class. The TDI’s did not accomplish anything similar to this. My Insight is for sale because some point in the very near future, my commute will be shortened significantly. At that point in time, it will not make financial sense to own 2 automobiles (4 door sedan and commuting coupe) for the same purpose(s).

___Good Luck

While its true that diesels are *slightly* dirtier than a gasoline car (more NOx, but virtually no carbon monoxide/evaporative emissions), the diesel engine's higher fuel efficiency reduces pollution along the entire fuel chain. Less fuel. Less tanker trucks. Fewer oil ships. Fewer wells.

That's why the EPA's GREET analysis *from well-to-wheel* ranks diesel-hybrids as cleaner than gasoline-hybrids & fuel-celled cars.

Tank to Wheel GHG rates are better for the gasoline engines by about the same percentage that WTW is better for the diesels, so it's about a wash.

As far as "which fuel pollutes more." diesel exhaust has at LEAST three known carcinogens and at least 40 harmful-to-human chemicals, while gasoline exhaust has many but fewer of the severely damaging chemicals.

From the California OHHEA website:

"Gasoline exhaust also contains cancer-causing 1,3-butadiene, formaldehyde and acetaldehyde. Diesel exhaust contains several dozen toxic substances and scientific studies have shown that workers exposed to diesel exhaust are more likely to develop lung cancer. Long-term exposure to particles in diesel exhaust poses the highest cancer risk of any toxic air contaminant evaluated by OEHHA. ARB estimates that about 70 percent of the cancer risk that the average Californian faces from breathing toxic air pollutants stems from diesel exhaust particles. The microscopic particles making up diesel exhaust particulate matter are less than one-fifth the thickness of a human hair. They are small enough to penetrate deep into the lungs, where they can contribute to respiratory disease."

So my guess is that the more diesel engines we keep off the road, the lower the lung cancer rates will be.
