British motoring mag Autocar is reporting that the new Accord diesel we recently told you about will get really good mileage. That might seem like a no-brainer, but when we say "really good," we mean it. Like more than 60 mpg really good. Autocar says the diesel will be good for as much as 62.8 mpg when it appears in a dealership near you. That's 52.3 mpg here in the States, by the way. Honda's new clean diesel is apparently based on the current 2.2 i-CTDi, and when fitted in a Euro Accord, it achieved that staggering 62.8 mpg at a recent diesel technology convention in California.
Besides the stellar fuel economy rating, these new diesels wear the "clean" tag proudly. The catalytic converter on these Honda diesels is helping it meet the strict US (especially in California) emissions standards, running as cleanly as gas engines. They do it by converting nitrogen into ammonia, which is then used to further diminish the remaining NOx gases. The new Accords should show up in September, but we're not sure if the diesel will be available from the get-go or if it will appear down the road.

      How did you convert from the European 62.8 mpg to the American 52.3 mpg? The source article at Autocar made no reference to the 52.3 number.
        • 8 Years Ago
        The British (Imperial) gallon is 20% bigger than the U.S. customary gallon. Apparently we use wine gallons while the Brits use ale (beer) gallons. Anyway, simply divide 62.8 by 1.2 to get 52.3.

      Like Oblatt, I'd rather have a Jetta TDI. The last gen got 50 mpg highway, and the new version is supposed to get 60. That and I'm looking to replace my Saturn wagon with a new wagon anyhow...

      If there was one new car that has my attention, it is this. I have always liked diesels and Accords. The two fused together sounds most interesting. Now if they just don't make it look like a flamey Bangle piece, which I am starting to think they have... =(

      So what will Toyota's response be? Will they build a Diesel Camry or will they tweak the Hybrid Camry to get more mileage.
      • 8 Years Ago
      62.8 MPG was achieved by the Accord CTDi in California! Last time I checked California was one of the "states" and no conversion from Imperial Gallon to US Gallon is required to determine how many California miles per gallon equal in the remaining states.

        However, Autocar is a Brit car magazine with Brit readers and they use Brit measures. So it follows that they'd be reporting the Accord's economy according to the imperial miles per gallon their readers use and are used to, rather than changing to US mpg to report on something that happened in the US. Because that wouldn't make very much sense now, would it?

      Autocar, a British magazine quotes the 63 Imperial for the UK Accord. Which is much smaller then the US accord. Its the Acura TSX. The US model Accord will not get 50 mpg, and the mileage should be closer to other larger diesel saloons. Also the diesel unit only makes 140hp.

      "A European-market Accord fitted with a sophisticated version of the 2.2 diesel, and capable of 62.8mpg, was recently shown at a diesel technology convention in California."
      • 8 Years Ago
      Don't forget that the European Accord is the same as the Acura TSX. So I'd imagine that this would end up being an Acura diesel.

      BMW have just released a 118d that does about the same mpg. Have you reported on this Autoblog? I haven't seen.

      How about a Diesel Hybrid???

      One that gets about 80 MPG in a full size sedan.
      • 8 Years Ago
      1 imperial gallon = 1.200949 gallon (1.2 is good enough)
      • 8 Years Ago
      I live in the UK and drive a Accord 2.4 Type S (TSX to you guys) and average 30 - 35 mpg (imperial gallon). The diesel saloon is rated at 52 mpg and a real world recent test put the mpg at 48.

      I am considering the station wagon which is sold here and have driven the diesel 6 speed. Honda does lose sales by not having an auto and would need one for the us market. Impressions - not as fast as the 2.4 but not really by much at least up to the speed limit !- very quiet at motorway speeds partly due to the high 6th gear - about 2000 rpm at 70 mph. - but i did miss being able to rev to 7000 rpm !

      So what will Toyota's response be?

      Toyota is selling their soul to hybrid technology. Honda did the cost/benefit analysis on a hybrid version of both the Accord and CR-V and passed. With the new EPA test procedures the improvements in MPG are just not that significant for larger cars and trucks.

      A diesel Ridgeline would rule.

      The stated fuel economy for the Euro Accord with the CTDi is 42.2 city/61.4 hwy/52.3 combined. I ran this through a conversion (see below for link) and arrived at:

      35 MPG city
      51 MPG highway
      44 MPG combined

      Still not shabby, but I think 52 miles per gallon is a bit optimistic.

        • 8 Years Ago
        The "new clean" Honda diesel is said to operate in the "lean" mode 95% of the time. I suspect that will add between 8% to 16% to the mpg ratings.
