Hybrids have now been hyped up beyond their own capabilities, so we find ourselves eagerly anticipating the comeback of the diesel engine. Volkswagen is sure to be one of the big diesel players in the beginning, having just announced its new TDI engine yesterday. But it looks like Honda might be in an even better position to bring oil burners back. Peter Nunn, Winding Road's roving reporter embedded on the isel of Nipon, claims that Honda's first diesel application in the Accord sedan will replace the Accord Hybrid sedan when it goes on sale around 2009.
The diesel in question will be an ultra clean 2.2 - 2.4L four-cylinder able to meet the toughest emissions standards in the world, i.e. California's Tier II / Bin 5 standard. Nunn reports that the Accord Hybrid will be "quietly retired" upon the arrival of the four-cylinder Accord Diesel, which should be able to handily trounce the outgoing hot-rod V6 hybrid in fuel mileage at the same time delivering decent get up and go. For those wanting more power, Honda is also planning a diesel V6 that will first be used in the Ridgeline before being disseminated across the lineup in its vans and SUVs.

Honda's enthusiasm for diesels is exactly the kind of support this old yet new again technology needs to get back on its feet in the U.S. Honda's aggressive R&D dept. is no doubt developing diesel engines that will change many a mind when it comes time to choose a new a green vehicle.

      Hate to burst your bubble: Peter Nunn is an idiot. Honda's not going bail out on an Accord Hybrid in favor of a diesel model. You can call it ultra-clean or whatever, a diesel is still a diesel. With the exception of the ten or so bitchy diesel whiners on this blog site, no one wants to buy a diesel car in America. Diesel is a stigmatized word in this country after the crap Mercedes rolled out thirty years ago.

      Dead-on. I have Jetta IV TDI bought new in 1999 that has logged over 400,000 miles. The engine and 5-speed transmission have been great. Not so the two turbochargers, numerous MAF sensors, broken glovebox, windows falling into doors, non-existent radio reception, peeling rubber interior, seized windshield wipers, burnt out heated side mirrors, two heater motors, on schedule (every 30000 miles) burnt out tail and/or headlamps, CEL on since 80000 miles and incredibly ignorant dealers who think it is all normal. Needless to say, a Honda with a diesel is my daydream and VW's nightmare.

      "JP, I agree, but I think it should be a Diesel Hybrid that works in Series as opposed to in parallel"

      LOL, you're selling it to the wrong crowd. Series hybrid is still a hybrid, which is really an EV. The pro-diesel crowd here will not accept any EV car, even if it's supported by a diesel engine, otherwise, they'd be hypocrites.

      "Erm, Audi's V6 A6 TDI hits sixty in 7 seconds..."

      Sure, BMW makes a great, fast diesel too...

      ...but we are talking about the Honda 2.2l diesel, which is NOT in the same category as the Audi or BMW diesel.

      Second, just because Audi, DCX, and BMW have performance diesel doesn't mean that they would put diesel into EVERY model that they make. The truth is that diesels are NOT cheap, and manufacturers have to price them accordingly. The diesel price premium will put a limit on sales, and it makes no sense for DCX to be putting diesels into lower-profit models.

      It took YEARS for Jeep Liberty to sell pass the 10,000 units figure, and with poor sales of the 300C, DCX would be a FOOL to sell more diesels outside the Mecedez, SUV and trucks market.

      YES !!!! TO Honda.

      It is a matter of time, refinement or design before virtually all auto manufacturers will offer diesel power plants in all types of vehicles.

      The time is now.

      Audi has been sucessfully racing with diesel powered cars lately.Wonder why? Probably have diesel engines in European Audis now. Sure as hell impressed me to know a diesel engine can compete with the slick, mega powered gasoline/alcohol engines.

      A diesel hybrid? Sounds ideal considering all technology that is currently available. Do wonder if premium $$ will eliminate that cominination ?

      As technology evolves I'm sure ther will be better alternatives for power sources for autos.

      Will the increase in diesel autos cause an increase in diesel fuel prices?? I know the BIG burner's are the 18 wheel trucks but perhaps the oil refiners will produce more diesel fuel as gasoline use declines in autos.
      And hey, can't diesels burn other sources of fuel and not just petroleum based fuel? Or are the the new ultra clean diesel fuel burners designed specifically for petroleum derived diesel fuel?

      What did Mr. Diesel use as a fuel when he developed the engine that bears his name?

      I'm thinking way too far into the future. Honda has just made the announcement.

      Enuff

      "It does not take a rocket scientist to figure out that combining into a Full Plug-In BioDiesel Hybrid that gets about 80 MPG to 100 MPG is the way to go."

      It does not take a rocket scientist to figure out that such a car would be cost-prohibitive. Take a one turbo-diesel engine (with an added cost of $1000), make it meet the new emissions regs, (an added cost of another $1000), add in the hybrid powertrain (an added cost of another $3000), and enough batteries to make it a useful plugin (another $3000). $8000 will buy quite a bit of gas.

      I'll be one of the first people in line to buy an Accord diesel. Just let it come with a 6 speed manual, OK Honda?

      #19: On the Mercedes models, the urea will last the duration of scheduled maintenance intervals, which is 1 year or 13,000 miles. Drastically different from, "where you have to actually fill the reservoir every month."

      Now, all honda will need to do is convince the fuel industry to get more diesel (or biodiesel) pumps out on the streets.

      Sometimes i wonder if its a good thing these cars have such great range, just to be sure you've got enough legs in your to help you find the next diesel filling station!
      Or you could get a biodiesel conversion and run on old fryer oil... so long as you live in a warmer climate where the oil won't solidify in your fuel lines.

      #4: Taxes.

      About 10 years ago or so, most states raised taxes on Diesel up to "price match" that of gasoline. The ULSD rules haven't helped.

      When I started driving Diesel cars in 1982, Diesel fuel was half the price of gasoline. When others were paying $1.20 to put unleaded in their firechicken V-8s, I was paying .58-.63¢ to put barely refined crude into my VW Rabbit, and getting 50 MPG to boot.

      #40 - OK I accept your calculations that the Full Plug-In BioDiesel Hybrid that gets about 90 MPG would cost about $8,000 more in initial cost. I (and a few million other folks) will gladly pay the premium up front to have super high mileage and feel good about our minimal impact on the environment.

      I know for a fact that the 2005 Honda Accord is already a CA Tier II Bin 5 LEV II vehicle. So, they're coming out with this "eco friendly" vehicle at least 4 years later that is somehow better?
