When diesels first hit the American market after the gas shocks of the 70's, they were unreliable, smelly, loud, and rough. They did get better gas mileage than comparably-sized gasoline engines, but in the eyes of the American public, the negatives of diesel tech far outweighed its positives. Diesel engines have gotten far better in the past 25 years, with Europeans buying more oil-burners than petrol engines. $3.00 per gallon gas (or worse) is helping to usher in a second renaissance for the diesel, and Honda is going all-in with a 3.5L dieselV6 for the US market.
Honda's forthcoming engine, which should be arriving around 2010, should achieve 30% better fuel economy (or more) than a comparably-sized gas engine, which should alleviate some of our pain at the pump. Honda plans on installing this V6 diesel delight on larger vehicles like the Odyssey minivan, the Ridgeline, and the Pilot. We think the new V6 will go along nicely with the planned four-banger in the Accord, and it will certainly help the folks from Tokyo compete with the many diesels the competition has planned for the near future.

      You would hope for 30% better mileage. Diesel has 30% more energy measure for measure with gas.
        • 7 Years Ago
        No.
        Without bio-diesel try 11% at best over 'straight' gasoline. 10% ethanol reduces the energy by 3% so it is always going to be less than 15% until the ethanol goes to ~15%

      Hello from Ireland,

      The european accord (looks like one of your acuras) has had a 2.2 diesel for a few years now it develops 153bhp and i think 295lbft of torque. It delivers its power very like a petrol but with much more mid range punch, and is one of the quietest diesels I have driven. Diesels cost a lot more to produce and i would think it would be around $3,000 more expensive then the petrol version. This engine is also in the crv but I have not had the pleasure yet. Based on the size of your gallon the car will achieve about 40mpg.

      Ian -yes.

      The Fiat group makes some of the world's best diesel engines - 1.9 litres and 190bhp, with realtime economy in the very high 40s - and they too are close to production with a new petrol (gas) engine (electro-magnetic valve actuation) delivering 90-110bhp and delivering fuel economy in the high 60s. (All mileage UK figures). This motor is only the smallest part of a new modular engine which, in two litre form, might well give similar economy to a good diesel?

      Euro regulations are forcing manufacturers to improve CO2 emissions, and Fiat is the corporate leader here.

      I hate to be negative, but I heard this song an dance before. I will believe it when I see it.

      Someone please correct me if I am wrong, outside of trucks, is VW the only car company here in the states that has cars with diesel?
        • 7 Years Ago
        Mercedes sells diesel
        E320 bluetec
        GL 320 CDI
        ML 320 CDI
        R 320 CDI

        • 7 Years Ago
        VW isn't currently producing diesel cars for the U.S., though you can get a Touareg TDI. The only diesel car available right now is Mercedes' E320 BlueTec (and they're also selling ML320 and GL320 diesels if memory serves).

        But, 2008 will bring a few more diesels. For VW, I'm hearing March 2008 for the Jetta TDI (including the wagon version), and earlier news had the Tiguan crossover getting a TDI in late 2008, but we'll see.
        • 7 Years Ago
        No, in '89 Ferrari brought a NA 2.2L diesel mini van to the states. It really wasn't all that popular though so they've stuck with the regular petrol engines for the minivans they bring here. They still have great aerodynamics and low weight, so that helps MPG.

      Prediction: GM will jump on the Diesel bandwagon and build passenger cars with crap diesels, and once again ruin the American public's interest in diesels.
      • 7 Years Ago
      This isn't that new in terms of news. You'll have all the lemmings who used to hate diesels jumping on the bandwagon now that honda "thought of it."

      Solid replacement for their sh*t pile hybrid though.

      I'll be happy to see clean diesels from everyone.
        • 7 Years Ago
        Good point Aaron, if it was Ford who bring a diesel here, there'll be lots of sceptimism, but to quote Pete DeLorenzo of "Autoextremist", if it's "holier than you" Honda.....

        "The brilliance of Japanese car manufacturers is that they actually LISTNED to what the customers wanted and built cars that catered to what the buying public wanted."

        I think they menaged to believe then they listened to us, when I saw the Civic being "bigger, longer and wider" over the years, dropping the Prelude and over the years Accord looking to be more and more like "granny grocery-getter" and being more common (to the point of being "too common") with the same bodystyle (do you wish to have variations like a hardtop sedan? ;-)) well Mazda still have some "zoom-zoom" spirit in their cars (I hope the next-gen Mazda 6 will retain some "zoom-zoom").

        And bringing Acura with a V10 engine like the future NSX(?) http://www.autoblog.com/2007/04/25/one-powerful-nsx-acura-supercar-to-have-500hp-at-23-5-mpg/ even for 23.5 mpg, I hope it won't have the same fate as the original NSX.

      A 2.0 L diesel in a heavy van would be quite a wickedly SLOW performer on the road IMHO.
        • 7 Years Ago
        From all I have heard Honda were going to shp a NA diesel engine. I have heard nothing of a turbo variant for NA in the near future. Have you?
        • 7 Years Ago
        Don't forget that many on this site hate hate anything Japanese. The loyal and blind allegiance to American Crap Cars is the reason why the American car companies faltered. The brilliance of Japanese car manufacturers is that they actually LISTNED to what the customers wanted and built cars that catered to what the buying public wanted. I can't wait for the Honda Diesel to come ashore. Finally Honda will address the issue of not having any low end torque!
        • 7 Years Ago
        No offense, Honda Lover, but your name and much of your post exemplifies the other end of the "loyal and blind allegiance" spectrum. For every reader of this blog that touts American cars as the best, there is at least one reader insulting those people and touting Japanese cars as the best.

        Neither statement is an absolute truth. The reality has many variables and falls somewhere in the middle depending a customer's needs/wants.

        That being said, I am very happy to see more diesels coming. I like Honda engines and am eager to see what they can do with diesel. My dream is to see turbo diesel hybrids. Anyone want to venture a guess as to who will bring that to the US market first?
        • 7 Years Ago
        Note that the 2.2l 4-cylinder diesel is destined for the Accord:

        http://www.autobloggreen.com/2007/06/07/2009-honda-accord-diesel-to-hit-52-mpg/

        ...but they're working on a 3.5l V6 for heavier vehicles. A 3.5l diesel in a minivan would rock!
        • 7 Years Ago
        2.0l inline 4 turbo diesel can deliver 204hp and 400Nm 1800rpm(latest BMW 2.0l diesel engine) running extrem clean with CO² 138g/km with great mpg... diesel have extrem torque at low rpm and can move things much quicker as petrol engines of the same size.. the lack in knowlege about state of the art diesel engine technology here at autoblock is amazing
      • 7 Years Ago
      Most of the Japanese car makers provided diesels in the eighties. In comparison to gas, few were sold. They weren't unreliable and in fact very reliable. A diesel that smells and sound like diesel, won't sell and as long as people smell diesel oil when filling up, they will not like them. There will be no great demand for diesels and Honda is taking a chance.
        • 7 Years Ago
        "and Honda is taking a chance"

        And I think they will be richly rewarded.
      • 7 Years Ago
      Next to hybrids, diesel would be next in line for less co2 emissions (latest diesel engines, mind u)
      • 7 Years Ago
      I still hate the smell of diesel fuel though. Just the fumes from tracking some of it onto my car's floormats makes me nauseous.
        • 7 Years Ago
        Not to fret, no one will be forcing you to buy a diesel car.
      • 7 Years Ago
      The diesels will cost a lot more than the gas version, though--think $2000-$3000 more. Doing the math, for 12K mi/year, 30% FE savings on $3/gal gas gets you about a 5 year payoff timeframe (assume 25mpg for gas version).
        • 7 Years Ago
        welcome in the year 2007... long time ago that diesel were much more expansive... most modern diesel powered cars are as cheap/expansive as their petrol powered counterpart..

        example in Germany the 2.0l TFSI Golf 200gp/280Nm and the 2.0l TDI Golf 170hp/350Nm cost nearly the same... the petrol is little bit quicker in 0-60 acceleration and topspeed.. in daily drive with rolling acceleration the petrol cant drive away the diesel... and the diesel get much better mpg... diesel 50mpg > petrol 26mpg... the reason why over 50% of all cars in Europe are diesel powered..
        • 7 Years Ago
        other good example...

        petrol
        Audi A4 3.2l FSI V6 quattro 255hp/330Nm
        38,350Euro in Germany
        diesel
        Audi A4 3.0l TDI V6 quattro 233hp/450Nm
        38.900Euro in Germany
      • 7 Years Ago
      Mercedes also sells the R320 Diesel. :)
