I am a little bit fundamentalist on that. Diesel (especially 6 cyl) can be good on some kind of cars, but not on a sport coupe. I also practice cycling and I can tell you that there is really a difference when I train around cars in US and in France. Diesel exhaust gas really sucks with the particules, but the diesels you will get in US will be the cleanests, and you will get 6 cylinders, so not so bad. But even a 6 cylinders diesel vibrates at idle and what is really diferent is how the engine behaves, the torque just decreases after 2500 rpm which make the sensations really differents. |

No, LSD standard for the 135i. Probably something that will be available through the new BMW Performance catalog.
And yes, in the US it is officially called the 135i. No 2-series designation.

torque yes but i believe that diesels are still far behind in hp/L even with the recent advancements(higher rev limits etc.)-the petrol engines also get revvier all the time. also, although the torque is great it's my impression that often these super-torquey diesels aren't offered with manuals because of lack of a manual clutch with an adequate torque rating. i personally would be very interested in a 335d for example or a torquey 1er if it came with stick.

Very important...Many 335i owners wish that an LSD was optional. The car really needs it to keep the power down on the road. The 1-Series coupe will certainly need it even more due to the shorter wheelbase and the loss of some weight compared to the 3-Series. |

[quote=PierrePHRWEAUX;3312]Actually, the main difference is that the carnot cycle (gasoline engine) has a theoretical efficiency of 37% and the diesel cycle 42% (So just 5% gap in efficiency)....quote]
would not the difference in efficiency be better conceptualized as 13.5%(42/37) in the sense that this ratio would translate to perhaps a comparabe fuel-efficiency ratio? |

Otto cycle = 37% Diesel cycle = 42% (42-37)/37=13,5% difference. (I thought too fast) I think the problem with diesel engine is that to have the best combustion possible and thus the best efficiency, the engine has to run slow. It's probably due to tha fact that fuel is injected in a very high pressure cyclinder which make it difficult to spread. That's why it burns in excess of air and produce NOx. The fact that it has to run slow make it very suitable for big engine (trucks) an for industrial applications. |

Edit: I do agree with MPower that is is highly doubtful that we will see LSD as an option on the 1-Series Coupe As he mentioned BMW AG is reserving that for M cars only. |

But, the bad news is if all that is true (brakes, LSD...), I doubt there will be a M1. |
