Click above for high-res gallery of the 2009 Acura TSX

At the 2008 Detroit Auto Show, Acura showed off a new 2.2-liter four-cylinder diesel engine and announced it would debut a production version in 2009. Informed speculation says that the oilburner would be equipped in the new TSX, a re-badged version of the European Honda Accord that currently offers the engine. Honda engineers have even presented documents outlining the new exhaust developed for the engine in the last two editions of the Society of Automotive Engineers World Congress.

Unfortunately, it looks like we might not get a chance to sample a diesel TSX in the U.S. after all. An anonymous poster on the MotorTrend forums is claiming that Honda has not been able to pass emissions certification with the automatic transmission TSX diesel. The manual transmission version is fine, but the poster claims there wouldn't be enough demand in the U.S. market for the manual-only model and Honda will therefore drop the diesel altogether. We don't know if this is true, and Acura has not yet responded to our request for a comment. It will most like be a "no comment" anyway.

For what it's worth, we're suitably dubious about the source and the information, particularly considering that modern cars with electronically controlled automatic transmissions typically perform better on emissions and fuel economy. This is primarily due to the engineer's ability to have more control over the interaction between the engine and the transmission, and less to do with the person behind the wheel. Hopefully the story is untrue, because it would be nice to finally get a Honda/Acura with some low end torque.

      That style of short-sightedness is what cost the domestics so dearly.

      Diesel prices are dropping as well at an incredible rate, albeit perhaps not as incredibly fast as regular is dropping.

      If the market has shown us anything, its that you can't predict the prices of fuel one month from now, let alone 5 years from now.

      Its best to have options on the table.

        So do you want the diesel?

      Just looks at the sales of the Jetta TDI. This would be a win win, if they brought over the diesel TSX (Accord).
      • 6 Years Ago
      That's a shame. However, I would have thought anyone seriously interested in a diesel wouldn't have considered an automatic tranny anyway. I would have wanted the manual.

      A part of me died upon reading the headline, but thankfully it's likely an untrue rumor, especially coming from an anonymous blogger with dubious information.

      Wait what?? Honda couldn't pass emission regulations?? Are you telling me that foreign cars don't make the greenest vehicles? wow lol
      • 6 Years Ago
      uh,
      so they'd need to recal the software for hte tranny and lower the power a bit for hte auto in order to pass emmisions

      sound like a bogus call from that ananyomous poster

      Had sad for Autoblog to be trolling for information at that kiddy forum Motortrend.

      "An anonymous poster on the MotorTrend forums is claiming that Honda has not been able to pass emissions certification with the automatic transmission TSX diesel."------------ Are you serious?

        Seriously it probably was one of those Domestic Groupies who posted it.


        I wonder if other Auto Blogs use me as their "source"
        • 6 Years Ago
        um, no... it was me who posted it and I got it from the temple of vtec website so it wasn't one of the domestic groupies considering I am a Honda Fan Boy.

      Finally, the Yen is rising which should bring the competiton closer for our ailing automakers.
        • 6 Years Ago
        Yes the Euro was higher but the prices did not go up much if at all, which means they've been eating the deficit and its not good.
        • 6 Years Ago
        True, however, the Euro is falling, which means that the European offerings are going to be cheaper.
        • 6 Years Ago
        But Euro has been stronger than Dollar for a while, plus they have super strong Unions, that did not help Detroit much.



        Product, that's what matters.

        @ RG, IT IS FALLING NOW, LAST TWO YEAR DOLLARS WAS LOWER

      This article is why blogger's continue to NOT be taken seriously.

      Even if it turns out to be true, you've used an "anonymous poster" on a message board as your source. So friggin what if you qualified your article by saying that it might not be true. You shouldn't have posted this to begin with.

      In the end, you look unprofessional and just flat out stupid.
        • 6 Years Ago
        I wish I could say that blogs are rising to the challenges and standards of so-called "professional journalism", but it seems that in far too many magazines and newspapers the opposite is true. It's not unusual to quote unknown or anonymous sources these days.

        That being said, how often does one read about Honda not rise to an engineering challenge? Maybe they will have to take a different approach than what they intended, but I can't believe they would just give up. (If the story is true, that is.)

        No kidding, this kind of garbage is ridiculous!
