Those of us Stateside have been deprived of more diesel models than you shake an oversized fuel nozzle at, but it looks like the folks over at BMW may be on their way to curing our high-mileage, high-torque lust. The automaker's 286 HP, 427 lb.-ft. of torque 3.0-liter twin turbo engine may find a way under the hood of various models throughout BMW's lineup, likely to append the "35d" designation to the 3-, 5- and 6-series models. Fuel mileage should be up over 35 MPG, but there's no word on when it will arrive. If we had to guess, we'd say late next year.

      I will believe it when I see it. Seems like every company has "said" they are brining one. Months go by and all we have are petrol engines.

      I am hoping someone has done a "big picture" study of petrol vs diesel (emissions per "mile", like a petrol engine produces X of emission per gallon, and diesel produces Y of emissions per gallon), and shown that overall diesel are "worse". What I am trying to say is diesel might be "dirty", but they get better fuel mileage. So does the extra miles per gallon make up for the increase in emissions? If no one has done this....then we really can only say that diesel puts out more emissions standing still.

      I found a comparison of a diesel/petrol Aygo

      Diesel Petrol
      (g/km) C1/Aygo 107/Aygo/C1

      CO2 109 109
      NOx 0.240 0.010
      PM 0.011 0
      CO 0.180 0.370

      So really the only down side is the Nitrogen Oxide. IIRC the most concentrated element in the air is Nitrogen (with oxygen being second). I wonder if there is a way to filter/break out that compound to have just nitrogen and oxygen. Then diesels would be almost better :)

      Finally...i wonder how the acceleration will compare with the standard '35 models...
        • 7 Years Ago
        Poorly. Diesels accelerate slowly in all-out tests because they are low on HP.

        The good news is that due to greater torque availability at day-to-day RPMs, Diesels tend to accelerate quite well comparatively under more common conditions to what normally aspirated gas cars do.
        • 7 Years Ago
        BMW ... there are a lot of dieselheads in the US who lust after european diesels (as if there was anybody else making good diesels). That engine would probably be better served in the X5 but get it over here!

        BMW factory claim

        the 3.0l diesel with 286hp is avaible since a long time in Germany in different models

        335d (sedan 286hp)
        0-100km 6.2s
        0-1000meter 25.4s
        80-120km/h 4/5.gear (no 335d data avaible)
        80-120km/h 4./.gear 5.0/6.4s < 330d 231hp
        330d data just to get a idea what torque is made for
        6.7l 100km mix = 35mpg

        335i (sedan 306hp)
        0-100km/h 5.6s
        0-1000meter 24.6s
        80-120km/h 4/5.gear 5.3/6.3s
        9.1l 100km mix = 25.8mpg

        330i (sedan 272hp)
        0-100km/h 6.1s
        0-1000meter 25.5s
        80-120km/h 4/5.gear 6.2/7.7s
        7.2l 100km mix = 32mpg

        The big different... you need to drive a petrol car slow to get that mpg...if you push hard a 335i the mpg drops easy under 20mpg... if you push a 335d hard the mpg drops to 30...if you constant drive at 60mph over long distance the mpg easy gets over 40 to 45mpg

      I took these pictures of a 535d in San Francisco 2 weeks ago:

      Just the thing to make me consider BMWs again......I loved the 320D I rented in Portugal four years ago. Could only imagine what the six cylinder diesel is like. If only Mercedes sold their C220 CDI in the US, I wouldn't have gone for the '07 C230 I just bought...
        • 7 Years Ago
        I rented a new '08 C220 CDI in Italy last month. The thing was a real pleasure to drive, and the turbo-diesel had plenty of power for 150+ km/h driving (and good brakes when TomTom warned of a speed camera). Great handling and real comfortable. Like the looks too, except for the boxy front end.

      Umm...they announced this months ago. And its coming to CA. And the acceleration is decent...mid 6's I think. They've been selling this in europe for a while now so not like its a mystery.

      Sadly, forget us Californians, as CARB will stop that Bimmer diesel from crossing our borders.

      It'll nearly have to be shooting H20 out of it's tail pipe before CARB will give a tentative OK.

      We have such a messed up vehicular emissions policy in our state. In turn our state seems to lead a following of other states also, into the abyss of stupid, pie in the sky, environmental extremism.

      Because California and these other states seem to comprise so many potential consumer auto sales, many very clean diesel powered vehicles from abroad haven't made it to our shores. The R&D to qualify a diesel car or SUV for California and it's wacky ally states, shuns-away so many great diesel powered vehicles from being offered to the remaining consumers in the more environmentally "sane" states.

      So goes California, and the rest of the nation's drivers and or auto consumers suffer for our extremist-green policies.

      We even have to burn our own blend of unleaded gasoline, refined in our own California based refineries. Yet it has been proven that our unleaded isn't any better or cleaner burning than the Federal EPA Unleaded. In fact our California unleaded up to a couple years ago had MTBE's in it, and was poisoning our environment. This was to oxigenate our gasoline. Found out CARB had a sweet heart deal with a Chemical firm in Texas that provided the poison to our gasoliine.

      Sorry, bimmer........you got a great product, but California will stop it as it has done with Mercede's latest Blue Tech offering.

      So sad. :(
        • 7 Years Ago
        Amen. In addition to the lovely things you mention, I personally love it when, twice a year our gas prices skyrocket when supplies dwindle while all of the refineries switch over from winter blend to summer blend and vice-versa. Stupid and wasteful.
        • 7 Years Ago
        It'll come to CA or BMW won't bother. We're BMW's number 1 market by far. And from all I've read, they'll make it happen.
        • 7 Years Ago
        First off, none of the automakers with any brains are going to bother with a diesel that doesn't meet the 50-state standard.

        Second, there is no changeover from summer to winter gasoline anymore. Most of the price spikes we see in Calif. are because of refineries shutting down for maintenance or the occasional explosion.

        The political fights over air quality in the San Joaquin Valley have gone as far as state reps with ag interests proposing stricter limits on ag in exchange for having any and every car older than X years rendered unable to be licensed or crushed. Thank god for SEMA, which helped stop that nonsense.
          • 7 Years Ago
          Chrysler's, Jeep division just started offering a Daimler sourced diesel in their Cherokee line for U.S. consumers a few months ago, but California isn't getting it.

          So much for 50 state compliant diesels being the norm. :(
        • 7 Years Ago
        Oxygenated gas isn't a California-only thing. It was mandated by the EPA in the winter for all cities over a certain sized based upon a (flawed) study in Seattle many years ago. California has recently been authorized to be exempted from oxygenating gas, the only state to get an exemption.

        We have a huge problem with smog in valley areas here in California. The primary component of this smog is NOx. Even the cleanest Diesels (like this) emit 7x as much NOx as a gas car.

        There's a reason we require these companies to clean up their Diesels, and that's because they are filthy. If companies want to sell Diesels here, all they have to do is meet the emissions standards for NOx that gas cars had to meet 10 years ago. If they cannot, I don't feel bad for them.
        • 7 Years Ago
        Great Valley? It's called the Central Valley by everyone I know.

        And I'm located in San Jose, CA. People don't burn crops here.

        Either way, it wasn't me who identified NOx being the problem, it was the EPA, and when they started to lower NOxes in the 70s, smog levels went down dramatically in the LA Basin (also not a crop burning area) and elsewhere. We have a lot more cars now, so we need to continue to drive NOxes (on a per car basis) lower.

        Again, get over the oxygenated gas thing, oxygenated gas is is an EPA mandate, not CARB. The study it was based upon wasn't even done in a CARB area!

        http://www.epa.gov/otaq/oxygenate.htm

        You cannot blame oxygenated gas on CARB. The use of MTBE instead of ethanol for oxygenation in California is partially California's fault, as CA didn't approve ethanol for oxygenation use until after MTBE was found to be a problem.

        Anyway, the real solution to that problem isn't to use ethanol (which drops fuel economy 1.5%) or MTBE (which hangs out in groundwater), it's to stop using oxygenated gas. It doesn't even work. The study was flawed.

        You say that the air has gotten cleaner and cleaner as we have tightened emissions controls (it's documented!). So why do you want to allow Diesels which don't meet the controls? If Diesels are reintroduced, air quality will get worse, as surely as if people switched to the least clean gas cars (which are allowed to put half as much NOx into the air as a Diesel).

        It's simple what the Diesel cars have to do to get on the market: be as clean as gas cars were 10 years ago. Is that too much to ask? I don't think so.

          It is referred to as the Great Valley in geologic terms.

          I happend to have been a geology major and use that terminology.

          I, too, reside in San Jose, and have resided in the S.F. bay area fro 59 years.

          I've seen the changes, I witnessed the onset of smog in the late 1950's to early 60's in the Santa Clara Valley/Silicon Valley.

          I also have witnessed the cleaner years as the smog has not dominated our yearly days as they did some years ago.

          We have made great strides.

          We also are beset with government graft, and favoritism. Extremist environmental policies lacking balance and fairplay to humanity in total, has cause loss of jobs and ruination of local economys.

          We are making strides, but I refuse to sign-up to the environmental army and say "Heil" to every thing that they spit out of Sacramento. :)
      • 7 Years Ago
      BMW has insisted, ever since they announced US diesel availability, that they will only do it if it'll be a 50-state car. And yes, I believe it's because BMW says CA alone would be BMW's 5th or 6th largest market. ~30 US MPG in mixed driving (my 325i does 22) and more torque than a C5 Z06? Not much to not like there.
      • 7 Years Ago
      Awesome!

      There was a time when it seemed like only old men with green VW's had diesel engines.

      This car is going to change a lot of opinions.
      • 7 Years Ago
      For those wondering about the california emissions, it's the same with the mercedes bluetec motors. while currently not legal in all 50 states, they will be along with the BMW lineup as the new diesels will get a special catalyst that will inject urea which in turn will reduce the NOx emissions.
      • 7 Years Ago
      @ Gary Blomquist -

      the Mercedes E320 CDi achieved EPA Tier 2 Bin 6 with a lean NOx trap, part of the basket of technologies that make up BlueTec. CARB's LEV II level is identical to EPA Tier 2 Bin 5 - they pushed Mercedes down the LNT path even for engines that large because they do not much like the idea of the alternative - urea injection.

      However, having demonstrated that LNTs simply aren't good enough for the larger diesels, CARB finally relented and produced a guideline that would allow diesels with urea injection systems to be sold in California and the other states that follow CARB emissions standards. Since these states account for roughly 1/3 of all light duty vehicle sales in the US, the decision has prompted virtually all auto makers to put their diesel projects for the US market into high gear.

      VW, Mercedes and BMW will all be selling clean turbodiesel LDVs in all 50 states by late 2008/early 2009 - that does include California!

      Audi, Toyota, Honda and others will all follow soon after, because high fuel prices mean consumers are now willing to spend more up front for fuel economy. Because of the high cost of both diesel engines and NOx aftertreatment, expect the bulk of offerings to feature displacements of 3.0L and above. SUVs and trucks are prime candidates. Only a few mid-sized models will feature ~2.5L engines with LNTs will be offered early on.

      Single-stage turbodiesels in the 1.5-2.0L range probably won't be coming to US shores anytime soon, the economics just aren't attractive enough.
        • 7 Years Ago
        Let's hope these diesels stay out of California. The effort required to keep them clean from day one does not set a pretty picture for these vehicles 10 years down the road. The last thing we need is more of those older Mercedes diesels shooting the black soot all over the freeway in a pass attempt.
