It's not actually a twin turbo, that would imply that the turbos are the same size. But actually a bi-turbo like the 135 and the 335 where there is a lower RPM one and a high RPM one.
If it comes down to cost and the diesel is available over here, I'd have to take the 123d over the 135i. If cost isn't a factor, then the 135i will be in my driveway. |

Actually, you have that backwards. The N54B30 engine in the 335i and 135i is a twin-turbo, i.e., two same size units each driven by exhaust from 3 cylinders. The bi-turbo diesel's two units are of different sizes, the smaller for quick response and the larger taking over at higher rpm for max power. But perhaps that is what you were trying to say and I misunderstood.

And as far as performance goes, it's been proven that diesels can be fast, too, while maintaining much better MPG figures. Don't forget how much cheaper it is in most of the world as well.

Tell yah what.
If a Diesel BMW is going to ruin the image, I'll gladly strip the blue mit white off, and enjoy the exceptional handling AND performance AND MPG all to myself... Then, after a bit of software upgrades, I would almost bet that the only thing most gassers would see -is the rear bumper. And if I come across any church buses...

^ haha great post and profile.
why do you say that? because there is traditionally no love in the luxury market for anything with 4 cylinders? to me, thats the best reasoning as to why we will actually get the 123d, it sure as shit wont feel like what the 4 cylinder haters are afraid of.. (no power at low rpms). id like to reiterate the point that was made earlier that this has the potential to completely change the US perception of diesels. |

There's a reason why I chose a 318i over a 323i/325i/328i when I bought my (current) E36. Unfortunately, if BMW doesn't start offering 4-cylinder diesel cars, I may not invest in a new BMW and may just stick with my current ride...or see if I can sneak an M47 motor over from a UK wrecking yard and install it myself. :wink: And with regards to the 'sporting' nature of BMW diesels, especially 4-cylinder diesels, keep in mind that BMW has successfully raced a 4-cylinder diesel, and it won races based upon speed, not mileage: "If environmental friendliness doesn’t rev your engine, you may be interested to learn that a tweaked version of the 320d became the first diesel car ever to win a 24-hour endurance race, arguably motorsport’s toughest test. It won by an amazing six laps - not because it had to stop for fuel less often, as BMW are at pains to point out, but because it consistently posted the best lap times." Motoring iAfrica.com -D |

I feel for, and agree with, all of you 4-cylinder diesel fans. However, it's just not going to happen in the forseeable future. BMWNA has repeatedly gone on record that the 6-cylinder will be the low-end engine for North America. When we finally get a diesel in a car (not SAV) it will be the twin turbo 6. Mark my words.

BMW has stated that they will be bringing diesels into the US with the the X5 in 2008, so you're correct again. This will in all likelihood be the 6-cylinder TT diesel, so again you're spot on. The other 5 series will then likely receive the diesel to followed by the 3 and hopefully the 1. Although a 135d sounds very nice, I think that a 123d is more likely. A 135i already has a cramped engine bay and weight issues, so I suspect that 135d would be even worse. If the US 1er gets a diesel, I would bet on a 4 cylinder. Of course there's that big "If". I would love a 123d, but if I have to get a 135i or 128i my life will hardly be over. They all look to be great cars. :roundel: IMHO BMW's diesel technology has the potential to really change some perceptions in the US. Time will tell. |

Oh well, we can still hope and besides a 135i is so good that I wouldn't even feel that cheated if the 123d was not available. |

Every car model/engine combination that BMW sells in this country has to get certified to be allowed to sell here. That costs millions of dollars to do. There would be no return of investment in the certification process, likely only shifting sales from one BMW model to another (no net new sales), and they would lose a ton of money.
I don't see it happening without a huge campaign to push deisels in this country, along with biodeisel education. Biodeisel availability or not, deisels are viewed as dirty and rough by most in this country. I still think about those old Benz deisels with cakes of soot on the back bumper when I think about deisel cars. |

I agree it's going to be an uphill battle to change the viewpoint of most Americans regarding diesels. However, those of us that have rented current small diesels in Europe know that viewpoint is no longer applicable. My only concern is the US emisions requirement for adding the urea based mixture at regular intervals. That will slow the acceptance of diesels here--too bad.

The last diesel I drove in europe was an Alfa 156, which had the 2.4l tdi. Even with my wife and 2 kids, plus luggage for 4, that thing could sit there and burn the tires off the wheels. There wasn't a lot of top end, but that torque down low was a blast.

^IF they just bring it over, period -I'm in.
Also. With the latest switch to a low sulfur fuel here in the states, my 3/4 ton 4x4 Cummins Turbo Diesel has NO black smoke that I've been able to spot. No black around the tail end either. Thats saying allot when I see tons of old decrepit cars that "somehow" pass emissions testing every year, belching smog more so than my 7000lb diesel truck...! Which, by the way -averages 20-23 MPG and has enough torque to pull over a house and has been known to last over 500,000 miles before major engine rework is ever needed...

For those of us that have way too much free time at work, there was an interesting study completed by UBS Investment Research that focused on---- "Is diesel set to boom in the US?" dated May 24, 2007 vs. HybridsThe conclusion were:
Lowering CO2 emissions in the US: Is diesel or hybrid best? US regulators may soon move to set higher fuel economy standards, accelerating demand for fuel-efficient vehicles. At present, hybrid technology appears to be the preferred route in the US, but diesel can deliver similar benefits at lower cost. Diesel already dominates in Europe. The conditions may be right for a diesel boom in the US, in our opinion. A detailed cost/benefit analysis of the two technologies This report is produced in collaboration with Ricardo, experts in automotive technology. We have undertaken detailed analysis of the relative economy benefits, cost penalties and legislative constraints of diesel and hybrid. Diesel is a lower cost option; legislation - the key obstacle Ricardo forecasts growth in both technologies, but expects diesel to prevail by 2012 (1.5 million units versus 1.2 million hybrids). Diesel's cost burden is lower than hybrid's for similar fuel economy - even with the 'clean' technologies needed to meet tough US emissions regulations (including California). Diesel's cost lead over hybrid is most marked for larger vehicles (crossovers/SUVs). Diesel is easier to invest in than hybrid: Key stock ideas Diesel and hybrid growth should benefit key stocks within our coverage. Diesel plays are Toyota and battery makers (JCI).looks set to benefit the German OEMs (BMW, Mercedes, VW) and Honda, plus key suppliers (BorgWarner, Denso, perhaps Continental). The only obvious hybrid Basically, they predict 15% of the light duty vehicles sales will be made up of both Diesels and Hybrids by 2012. |
