    What are the pros and cons of diesel?
  • cericceric Posts: 1,093
    Mark, I don't think Honda make diesel engines, do they? I believe the Honda they sell with diesel engines in Europe are bought from other. The chance we see diesel RL is much slimmer than a Hybrid RL.

    In fact, I have been wondering why diesel engines can't rev as high to generate hp? Is it because they run w/o spark plugs? My impression with diesel vehicles stays at my dad's diesel truck. Outdated, I know.

    Diesels make boatloads of torque. Mercedes new E320 CDI makes something like 370lb.ft, more than the E500 does. HP is roughly 200. Im pretty sure that its faster than the gasoline E320, but not as fast as the E500. Diesel's problem in the US is largely its image. Americans have a perception of diesel cars as being dirty, smelly, and unreliable. (From '70s era european cars). While our European friends have seen diesels get modernized to the point where they are just as refined as gasoline, most companies just assumed "Americans just want gas" and so nobody really bothered to try and sell diesels other than a few VW small cars and the E class. Untreated diesel has a lot of sulfur content, which leads to dirty emmisions that wont pass some US emissions laws. (The new E320 CDI is only legal in 45 of 50 states). We're supposed to get "clean diesel" in 2006, which reduces the sulfur content and should allow the E to be sold in all 50 states. The E makes 27 city / 37 highway, and if combined with a hybrid system, it could probably get Prius levels of fuel efficiency, which would be spectacular.

    A turbo charged Honda engine (other than their jetskis) is REALLY unlikely. Like BMW, Honda simply doesnt do forced induction.

    My remarks are in no way meant to imply that I thought or think that Honda or Acura will bring an oil burner, blown or not, to the US or anywhere for that matter.

    In the US, the worm will soon be turning for oil burners. Why?

    Clean diesel fuel is coming soon. A 200HP E class with some 370foot pounds of torque would be both plenty fast (130mph no problem) and plenty plenty quick. Moreover, it would last longer and get better economy -- and with the afforementioned clean fuel, would actually be able, utlimately, to be considered an LEV.

    Honda may elect to go hybrid -- some are even considering hybrid with the internal combustion component of the marriage to be diesel.

    I do not claim, or at this point, believe, that Honda is one of these companies -- but stranger things have happened.

    And, who knows about turbo or other forced induction thought processes -- they are a potent way to increase volumetric efficiency and CAN reduce weight. Again, I have no notion that this will show up anytime soon in any Honda product.

    Diesels in the US suffer ONLY one true problem (or with the advent of clean fuel will only have one hurdle left to clear -- Image!).

    This, too, will change. As they say, money talks! Diesel is economical AND the high performance alternative, so far, if you want both economy and performance in the same package.

    Whoda thunk it?!?

    Honda Diesel Sets New World Records

    Honda’s new Accord 2.2 i-CTDi Sport has this week set no fewer than 19 world speed records and achieved 3.07 litres / 100 km (92 imperial mpg, ~76.6 US mpg) fuel economy to boot. British racing driver Robin Liddell and freelance journalist Iain Robertson were part of the European record-setting team.

    Amongst the speed records set, which were all achieved in Production Car Class B (2000 – 2500 cc), were 133.04 mph (1 mile flying start), 84.25 mph (1 mile standing start) and an average speed of 130.38 mph over a 24-hour endurance period. These records were all set at Papenburg high-speed oval test track in north-west Germany on 1 and 2 May, and are all subject to FIA ratification.

    Two production cars, randomly selected by FIA officials, were used to undertake the speed records, and apart from the fitting of roll-cages, racing harnesses and radio equipment for track-to-pits communication, no other modifications were made to the cars.

    Following the speed record attempts, the same two cars were then driven 419 miles from Papenburg test track to Wiesbaden, near Frankfurt in order to complete the fuel economy run. The route comprised of a mixture of motorway and non-motorway driving, during which one of the Accords achieved a staggering 92 imperial mpg (US mpg=~76.6) average.

    The project, whose aim was to demonstrate the performance and economy of the Accord i-CTDi, was a joint production between Honda, the FIA and Italian-based JAS Motorsport, who managed fuelling and pit-stops.

    Honda UK’s driver in the speed record attempt, Robin Liddell, who has previously raced at Le Mans 24-hours, as well as the American Le Mans Series and the BRDC British GT championship, commented: "The car’s performance is very impressive, demonstrated by the records we’ve achieved. Honda has made real steps forward in styling, ergonomics and interior design with the new Accord Diesel and now has a package that can take on the best cars in its class."

    A complete list of speed records, all subject to FIA ratification, is as follows:

    There is another attribute that stands out in modern diesels. In the past, gasoline engines had advantage in terms of power production for a given displacement, but thanks to the development of common-rail turbo diesel technology, the peak power numbers are close to gasoline engines (and at lower rpm) with more torque (at an even lower rpm).

    2.2-liter I-4 (gasoline): 145 HP @ 5500 rpm / 147 lb.-ft @ 4700 rpm (1994-97 Accord EX)
    2.2-liter I-4 (diesel): 140 HP @ 4000 rpm / 250 lb.-ft @ 2000 rpm (2003+ European Accord)

    But, even with use of aluminum block (a rarity in diesel engines), which makes the Honda diesel one of the lightest in its class, it is still about 100 lb. heavier than a comparable displacement gasoline engine. And although this diesel is considered one of the most refined in its class compared to BMW, Mercedes and VW diesels (from reviews in European magazines), the tag line “for a diesel” still goes with it. So, while diesels are getting impressive output, they continue to have some (diminishing) weaknesses.

    Now, Honda has come up with its own version of direct ignition gasoline engine, which is supposed to improve mileage considerably (capable of going as lean as 64:1). I believe it is being offered in one of the Japanese market vehicles using Honda K-series DOHC I-VTEC, and without VCM at the moment.

    So, development continues on both fronts (diesel and gasoline). As far as RL is concerned, I hope it gets some “hybrid treatment” instead of diesel for the American market.

    Hi, legendman: Thanks. I stand corrected. I remember reading the news in vtec.net, but didn't pay attention to the fact that it was a diesel engine.
  • lexusguylexusguy Posts: 6,419
    A hybrid RL seems like a much more likely option. Lexus isnt doing diesel any time soon, and if they want to compete with a hybrid GS350, gasoline\electric seems the most likely route.
  • varmintvarmint Posts: 6,326
    If Honda builds another diesel, it'll one for the European market. I expect they will soon build their own >2.0 for the Civic line overseas. That same 2.2 engine described above will soon be going into the CR-V.

    However, building one for the RL would be kinda dicey. I think that would be a lot of work for a small number of cars. Compare that with the need for more diesels in Europe and I think Europe will win.

    On turbos... Honda is not exactly anti-turbo. During development, they considered a turbo for the S2000. It was rejected as a result of concerns over turbo-lag. But as technology advances, turbo-lag is being reduced. The HSC concept mule was powered by a variable vane turbo of their own design. Never say never when it comes to these Honda guys. They use whatever tool gets the job done.

    All that said, if the RL gets an alternative power plant, I expect it will be a hybrid. The biggest hurdle for hybrids is their expense. When we're talking about the market north of 50K, buyers tend to me a little less cheap. ;-)

    I am glad to see this post. I was pretty excited myself to read it along with the various engine awards Honda received once more this year!
    In addition, I wanted to share my perception for the feasibility of diesel powertrains. Recent advancements in diesel engines have been ignited by the creation of a multinational effort to design more advanced engines. My knowledge is that all major automobile companies have participated to these efforts and have led to the development of "common rail" diesel engines. There have been already a few generations of diesel engines based on the "common rail" specification and basically that is the spec used in all diesel-powered european cars for the last 5-7 years.
    I bring this up because I believe that both BMW and HONDA are partners in the consortium overseing the "common rail" development. So I guess both can easily attain production of diesel-powered production models (as the Honda post clearly suggests).

    Do you know if Honda has the technology to compete with Toyota when it comes to hybrids though? For its high performance cars, Toyota is talking about 150+hp electric motors. Im not sure if Honda can match that.
  • ksomanksoman Posts: 590
    one thing interesting... in public perception, everybody mentions the prius when they talk about hybrids, but factually more than 50% registred hybrids in 2003 were civic hybrids from publicly available data.

    i dont know, why 150+ HP electric motors are such a big deal, toyota or not... the non-automotive world has some amazing array of high output ac & dc motors with some really fancy materials. given that so far all electric motors in hybrids have been DC powered, i'm not too concerned about either torque or HP. DC motors inherently pump lots of torque and fairly good amounts of HP starting at very low RPMs, that's just the way it is. As long as the manufacturer has the will and mechanism to balance the weight aspect or justify the weight aspect, the HP is a non-issue. I dont think toyota or honda really have done anything special about the motors themselves, its the application which is of interest and both seem to be in the same boat.

    Honda has showcased several hybrids with powerful electric motors. Here are the major Honda Hybrid Prototypes/Concepts showcased over last three years…

    2001 Honda Dual Note / 2002 Acura DNX (400 HP/AWD)
    3.5 liter DOHC I-VTEC V6: 300 HP
    Three Electric Motors (two front “in-wheel” mounted, and one mounted beside the “mid-mounted” gasoline engine): 100 HP

    2002 Acura RDX (250 HP/AWD)
    2.4 liter DOHC I-VTEC I-4: 190 HP
    Two front “in-wheel” mounted electric motors: 60 HP

    2003 European Honda Accord Hybrid (350 HP/AWD)
    2.0 liter DOHC I-VTEC I-4: 200 HP
    Two rear “in-wheel” mounted electric motors: 150 HP

    While Honda hasn’t offered a production hybrid with more than 15 HP (Civic Hybrid), it certainly has showcased several prototypes with more powerful electric motors (combinations) than are seen in Civic Hybrid and Insight. The Accord Hybrid is expected to have a 30 HP electric motor.

    For a car like RL, even 30 HP would do the magic because the top end is good already, and where the electric motor will really help will be the low end.

    BTW, while Honda’s current hybrids use “ultra-thin brushless” DC motors, Honda also makes it very own 80 HP AC motor, developed originally for Honda EV-Plus (electric vehicle) and currently used in FCX (fuel cell vehicle).

    Please join in! Things I'd like to see, and not necessarily in this order:

    1. 3.5L DOHC engine

    2. 300 ft-lb torque

    3. 19-20" wheel/tire option

    4. 0-60 in 5.5 seconds

    5. Top speed 156 MPH (simply to exceed the volunteer governor-limited 155 MPH top end imposed by some European manufacturers)

    6. Skidpad performance of 1.0

    7. Maintenance data display that shows number of hours on the engine - extra nice would be percent of time spent in various rpm ranges (does this make sense?)

    8. Nav system that could display dvd movies (Disabled if car was moving)

    9. Connection conduit to the NAV display system for radar detection devices

    10. Passenger seatback that completely folds back (180 degrees)

    11. Compartments to conceal goodies (especially one for a KelTec .380mm P3-AT)

    12. Audio system capable of playing MP3 files. That way I can listen to custom music and audio books.

    13. Power rear seats - simply for the "cool" quotient
  • legendmanlegendman Posts: 362
    These are a few of my favorite things:

    1. Wide, comfortable driver seat that will not pinch or squeeze a 200 lb. man

    2. Lose the metal in the center column and replace it with wood

    3. Lose the 3 small, round dash gauges and provide instead a one piece luminscent display like in Mercedes S class

    4. Lose the BMW 7 series trunk hump and offer clean lines

    5. Redesign the front end and make it less bug-eyed

    6. Vibrating massaging driver seat

    7. Leather wrapped steering wheel - no WOOD wheels!

    8. HVAC controls completely independent of the navi system screen

    9. Radio that will play cassettes too. I have tons of 'em!

    10. Fuel efficiency/fuel saving technology

    11. Good exterior color choices -- similar to BMW metallic offerings.

    12. Fold down rear seat(s) with trunk access

    13. An excellent braking system equivalent to BMW or better.

    14. Superlative ABS system equivalant or better than BMW's

    15. On-Star or equivalent

    16. One year complimentary XM satellite service

    17. Robust anti-theft system
  • cericceric Posts: 1,093
    Things I like to see available or standard:

    1. engine: DOHC 3.5L 300hp/270ft-lb
    2. chassis: able to pull at least 0.92g
    3. manual transmission - 6 speed
    4. hybrid - adding at least 100hp
    5. excellent brake (good point legendman!) Acura isn't really famous for excellent brakes.
    6. 18" wheels, at least 235mm wide tires.
    7. Reliability!!! Otherwise, I could have stayed with my '98 540iA

    See, my list is short considering all the known standard/available features.

    shotgun, I haven't seen a 3.5L engine naturally aspirated can put out 300ft-lb of torque. Has anyone? Nissan VQ can put out 270ft-lb. By projection, BMW M3 3.2L(255ft-lb) can put out 278ft-lb if increased to 3.5L. I hope to be wrong, though.
  • shotgunshotgun Posts: 184
    Ceric, I haven't heard, read about or seen a naturally aspirated 3.5L put out 300 ft-lb either...its simply "wishful" thinking on my behalf. It would be a major engineering feat if Honda/Acura could pull that off. Can you imagine the field day the automotive press would have if Acura came out with a 300HP & 300 ft-lb torque engine and the impact that would have on the performance capability of the RL. On its way to "smokin" most V8's in acceleration and top-end, Honda would lay to rest, for once an all, the criticism showered on it for not offering a V8 - it would become an instant cult "classic". I'm not, by any stretch of the imagination, an automotive technophile, however I do believe there are some engines out there whose ft-lb capacity equals or exceed their HP rating...And finally, you know, "300HP & 300 ft-lbs" simply has a very nice "ring" to it...

    cassettes???
  • hjcanterhjcanter Posts: 31
    I would like on the new RL:

    1. Most of what the other posts said

    2. Heated AND cooled seats

    3. Enough head room for a 6'3" guy who wears baseball caps

    4. Enough of a price difference from a 2005 a6 4.2 to get my 300+ hp

    I believe the RL will come in at about $49k and the a6 at $55-57k.
