There is nothing better than finding a few stray horses that were previously unaccounted for. Honda engineers were running tests on the Accord's 3.5L V6 engine when they realized it was spinning the dyno with more horsepower and torque than originally thought. It caught the Honda team off guard, as the powerplant has received no design changes to warrant the extra power. Regardless, the marketing folks have been quick to update the power ratings of the 3.5-liter 24-Valve SOHC i-VTEC powerplant. Here are the new numbers for 2009: 271 hp replaces 268 hp on all V6 models, 254 lb-ft. replaces 248 lb-ft. on automatic transmission models and 251 lb-ft. replaces 248 lb-ft. on manual transmission models. One would have to assume that the 2008 model made the same power, it just wasn't noticed... Thanks for the tip, Steve!

Excerpt from Press Release dated 8/7/2008

Testing of production engines for horsepower and torque output of the 2008 Accord V-6 has revealed that the average horsepower and torque produced by these engines is higher than originally estimated prior to the start of mass production. Though there have been no design changes to the engines to create more power, the horsepower and torque ratings for the 2009 models have been increased to reflect the actual output of the engines. For 2009, 271 hp replaces 268 hp on all V-6 models, 254 lb-ft. replaces 248 lb-ft. on automatic transmission models and 251 lb-ft. replaces 248 lb-ft. on manual transmission models.

      Accord vs. Camry? I'll take the Mazda6 (2009) over both of them on any given day.

        You can get more gizmos and desperate domsestic dealer rebates if you buy a Fusion though.

      At first Honda thought that they had built a simple engine: a basic powerplant for their people-movers. The engineers, as they walked away from the tired fruits of their labor, nodded to one another with a muted respect, for they felt that what they had done was good.

      They placed this mechanical heart within the metallic skin of one of the beasts which we call "cars". Deep within this skin and skeleton of steel and iron was a soul, and this soul was called: The Honda 3.5 liter V-6.

      And they thought that it was good. They placed, within the chassis, upholstery of cloth and leather and wood and beautiful materials the likes of which Chryslers have not seen in many a long year. To manage the cylinders' pounding heartbeat they used a box of strong gears and transmission fluid, and thus was the lifeblood of the beast directed to its wheels.

      But then, they discovered that the 3.5L V6 was more powerful than first thought.

        LOL. It's beautiful.

        "the likes of which Chryslers have not seen for many years."

        ROFL. How did you think of that?

        LOL. I haven't commented on a single article all day (boring topics IMO) but this post did make me laugh. Good one.

        It popped into my head. I thought it was funny.

        Thanks man.

      well this explains the upadted ratings form the new CandD.

      Considering the fact that there are still 'monday' and 'wednesday' motors out there... how accurate is any rating of power?
      by the title of the post, i was expecting 15 or 20, or to find out that honda down-rates their engine hp numbers.

      from the engine pics, nice to know they still use some of the same supporting hardware and cans from the early 90s (and possibly earlier than that)
      • 7 Years Ago
      I wonder if this bump in power affects the Honda 3.5-litre V6 delivered to other markets?

      They did this because of the MAZDA6 coming out right now. (272 HP).

      The V6 sedan is still gutless in the midrange because of VCM.

      >,>;; Funny, weird, and wow you have a lot of time. Should make this car poop diamonds and I'll get it in a heart beat.
      • 7 Years Ago
      Isn't this the same motor that lost 20HP on the last re-measuring?
      • 7 Years Ago
      What's the tolerance range on an engine power test? 3 hp seems like it doesn't warrant a change in the marketing numbers. But then again it is just a marketing number.
        • 7 Years Ago
        If the change is actually legitimate than it's definitely worth changing. Quite a few people spend a thousand dollars for a 3hp performance boost, as shown by many tuners.

        It's a lot more than what they are admitting to. Honda wants you to know there is more power there but at the same time they must protect the Acura powerplants.

        I bet the motor makes the same 286hp as the TL's did.

        I hate to toot my own horn....but I posted the following months back about the Accord Coupe.......

        Nov 1st 2007 3:24PM
        Has anyone else had the chance to drive the 6-speed Accord Coupe?? I did and this car is one fast ride!!! There is no doubt in my mind that if anyone hooks this car to a dyno they will prove that the 268hp number is only there to protect Acura. This car jumps out of the hole while the TCS is barely noticeable, although it is working hard, and pulls hard all the way to the top of 4th gear.

        Go drive one, you will be shocked. I have an '04 6-Speed Coupe and I never thought the extra HP and TQ numbers would feel that different.

        The Altima coupe is no match after you've stepped out of the Accord.

        @ Matt,

        Honda didn't want to get into a horsepower race with Toyota, like Nissan and Mazda have done. Toyota, as they should bumped up for a year-over-model and Honda subsequently followed. Not sure how you see this as a "ridiculous find". They knew it was there because that's what it was originally rated. If everybody else was trying to sell a vehicle saying it's "more powerful than yours", would you not turn around and say..."ahh...not really..."? A number of automakers do this, not just Honda. I see nothing wrong with it.

      Holy slow newsday, Batman!
      • 7 Years Ago
      GM's underrated their motors for years and I have yet to ever see anybody complain about it. Where have you been?
      • 7 Years Ago
      Whye does their manual transmission model have less hp? Usually, if there is variation in output with the transmission choice, it is the other way around.

      @ MikeW

      "How about Honda put variable valve timing into their V6 engines? That would require dual overhead camshafts"

      Do you know what VTEC stands for???
