Various 1-series questions
Anybody have a 1 series car with 3 cylinder engine and manual gearbox? I am wondering if it rev matches automatically, like the FWD cars with that engine.
With the M-Sport brakes, how small wheels is it possible to fit? On the newer cars with pressure sensors in the wheels, what happens if you install a wheel set without sensors, is it possible to drive without restrictions? |

I've test driven a 218i with ZF transmission.
the engine revs up real good between 1500-3500. after that it is a bit dead let's say. however, it sounds amazing. much better than 4 cylinder turbo engines. On the prototype testing videos of the 3 cylinder engine you can see that it can reach up to 170 hp and more which makes me think that the B38 engine has a serious hidden power in it waiting to be unleashed. About M-Sport brakes, you'll be needing 17" or more. When you install a set without sensors, the tyre pressure warnings will pop-up of course but you will be fine. There are a lot of people who hate run-flat tires here, and they are using regular wheels with non rft tires. Haven't heard any problems so far |

The B38 with some electric modifications is putting out around 230 hp in the i8. Quote:

With non-OEM 17" some care should be taken: http://f20.1addicts.com/forums/showt...0#post13117040 (the rim is three posts above there).
Then you don't seem to like BMW other than true ///M anymore: it looks like runflats are (suggested) mandatory otherwise. Why two? Aren't the rims available standalone? |

And even if runflats are mandatory when you buy the car, it doesn't mean it is mandatory to drive around on them. I don't know. Maybe they are. |

I wonder where all the runflats end up, because everybody I know replace them with normal tyres. Maybe a big pile at the dealer backyard? Or they deliver all the new cars with the same set of tyres, and just wait for the customers to get something else, so they can reuse them one more time?

RFT's remain no cost option but seems now for lci you to specify nRFT's if you want MPSS's implying RFT are the default. Shame as MPSS's are great as std fit to pre-lci M135i.

Yes, it looks they do, I just don't consider M135i so I missed that , my conclusion was based on BMW wheel configurator.
I had a small puncture recently and had to decide if I'd like to go for non-RFT Michelin Sport "whatever" they put on M135i and everybody here praised so hard in case of replacement. I have no issue with RFT and I did appreciate I had to do nothing to reach my home to research about probable replacement and then the tyre shop where they luckily just repaired it (at 10% of the replacement cost ): only half the pressure was lost so I guess it's all right now. |

Actually, it was about 1 bar which is roughly 1 atmosphere (thus it could be exactly nothing in fact ). Yet, the manometer did show the pressure making me believe it wasn't so bad and there was some compressed air preserved by the RFT technology and preserving the RFT empty run resource in return. I might have been wrong.

Yes, I finally leaned to the same interpretation too, recalling how the manometer worked (the school is so far behind! ). Thanks for the confirmation!
